Description

The invention relates to the field of use of jet engines.

In the future, when characterizing the developed technical solution, the following terms will be used:

- Air-Jet Engine (WFD) - any type of Air-Jet Engine, including Direct-flow VRM, Pulsating VRM, Turbo-Jet VRM, Air-Fan VRM, etc .;

- An additional pipe is a complex mechanical device capable of changing its geometry, as well as the volumes of supplied seawater (this is not shown in the images)

Known (US patent 3,684,054) is the design of a Jet engine exhaust augmentation unit, in which the exhaust gases of a turbojet engine are partially cooled using water injection and supplied to the nozzle inlet to increase the mass of the jet exhaust. Such a solution uses the internal energy of the heat jet to a minimum extent to perform additional useful work.

Also known (US patent 8092265) is a design of a vehicle with a jet propulsion device designed to move in water, according to which water is added to the reaction chamber of the engine and evaporated, the generated steam helps to create a vapor cavity around the vehicle, which reduces the resistance of the medium. Such a solution also only indirectly uses the energy of the thermal jet as such.

It is also known (RU 2093411) a solution for water injection into a jet engine with 2 goals:

1.Reduction of the partial pressure of oxygen in the combustion chamber (due to the fact that pure oxygen is supplied there, and the jet engine is designed for air supply)

2. The exhaust of the jet engine is produced in an unregulated outlet nozzle, which additionally receives water.

The disadvantage of the known solution should be recognized:

1. As you know, the normal pressure for combustion chambers of jet engines ranges from tens to hundreds of atmospheres. In the presence of high temperatures and pressures, this requires high-strength temperature-resistant materials, the use of thermal insulation systems, and the problem of throttling (thrust control) for jet engines has not yet been completely solved.

2. Non-adaptability (impossibility of changing the amount of water inflow, changing the shape) of the outlet nozzle does not allow such a combination to choose the optimal mode. There is no additional pipe in this solution (it is designed specifically to optimize the work with the exhaust jet at different engine operating modes.

3. The service life of jet engines is rather low, incl. therefore they are not used in long-term transport systems.

This application does not mention a jet engine, only all types of VRM.

Known solution SU 1743995 - "Hydrojet propulsion device containing a water flow pipe with a combustion chamber located in it"

In this solution, the combustion chamber is located in a profiled tube, the hydrojet propeller itself does not belong to any of the types of engines considered in this application (Air-Jet Engines).

There are also known methods of using the thermal jet of a jet engine to perform useful work outside vehicles, for example, for the needs of fire extinguishing. For example, it is known (CN, patent 1026756) the design of a Fire-extinguishing device by use of a turbojet tall-gas and water-fog, in which the energy of the thermal jet of a jet engine mounted on a fire-fighting vehicle is used to spray a jet of water supplied from the outside to a state of fine droplets (fog) and directed action of such a jet on the ignition source. In this case, the energy of the heat jet is not fully utilized, because does not mix directly with water for maximum energy output, but is used to break the external water jet into droplets. A similar principle with corresponding disadvantages is implemented in the utility model Urban turbo jet fire truck CN 202822566, which additionally provides for spraying not only water, but also fire-fighting powder (which is a dubious decision: fire-fighting powders reduce the temperature of hot gases and reduce the presence of oxygen at the combustion site, therefore, if the powder is added to a hot stream, it will work until it enters the combustion site). These solutions are designed for large-scale fires (extinguishing burning oil and gas fountains, etc.

The closest analogue is (US patent 3396538) the solution Water injection for thrust augmentation. According to this solution, a standard air-jet engine, mounted on a watercraft above the water level, is additionally equipped with a valve for taking seawater and injecting this water into the engine exhaust pipe. This mixes exhaust gases with water and increases engine thrust. The disadvantages of this solution are the incomplete use of the energy of the heat jet (due to the absence of a special additional pipe), limited by the throughput of the crane, the presence of a gas flow (with a residual high temperature, and therefore with a residual high level of internal energy) under the craft itself, which negatively affects stability and buoyancy (The flow of gases under the boat reduces its buoyancy according to Archimedes' law). It can also be seen that the engine is located in the ship's hull and operates in an air environment.

The technical problem solved using the developed method is that the existing designs and methods of using air-jet engines are based on the use of jet thrust - the force arising from the interaction of the air-jet propulsion system with a jet of expanding exhaust gases flowing out of the nozzle - products combustion of fuels with kinetic energy. The thrust is based on the law of conservation of momentum. In this case, the hot exhaust gases escaping from the nozzle have additional internal energy due to the high temperature, and this energy can be used to perform additional useful work.

The technical result achieved by implementing the developed method consists in increasing the momentum of movement.

To achieve the indicated technical result, it is proposed to use the developed method of using the internal energy of the thermal jet of an air-jet engine.

According to the developed method, an additional pipe is connected to the exhaust nozzle of the air-jet engine, the air-jet engine is installed on the boat below the waterline level, air is supplied to the air intake of the air-jet engine (patent No. 2661633), the flow of exhaust gases from the air is supplied to the additional pipe. a jet engine, as well as water, the resulting gas-steam-water mixture is used as a means of imparting an additional impulse to the movement of the floating craft.

Installation of an additional pipe (its shape and dimensions are variable during operation and depend on the characteristics of the air-jet engine, its operating mode and the required degree of conversion of the internal energy of the exhaust jet into an additional impulse of movement - not shown in the images) allows converting the internal energy of the exhaust jet into an additional mass of water, which turns into a gas-steam-water mixture.

The operation of an air-jet engine is always accompanied by a powerful high-speed flow of exhaust gas with great internal energy (high temperature of exhaust gases - up to 700 degrees C).

The proposed technical solution provides for the use of these properties of an air-jet engine to perform additional useful work or to influence external objects.

The specified technical result is achieved in that the exhaust nozzle of the air-jet engine is supplied with a sufficiently long additional pipe, in which the engine exhaust gases are mixed with significant volumes of water. Due to internal energy, the flow of gases turns into a flow of a gas-steam-water mixture, adding to the flow rate (which changes insignificantly due to the calculated geometric shape of the additional pipe in order to maintain the same pressure along the entire length of the additional pipe) an additional mass of evaporated and heated water, thereby increasing (in proportion to the mass of water passed through the additional pipe) the impulse of movement according to the formula P = M × V, where P is the impulse, M is the mass, V is the speed. The result is a significant increase in the outflow momentum.

The resulting impulse increment is the greater, the greater the mass of water entering the additional pipe, and, accordingly, the greater the mass of the working fluid formed in the additional pipe of the air-jet engine - a mixture of exhaust gases of water vapor and non-evaporated water.

The presence of an additional pipe implies a structural and functional unity, located behind the zone of high-speed high-temperature gas flow and connected to the engine exhaust nozzle, allows you to regulate the flow of water into this pipe (not shown in the figures) and its mixing in optimal quantities with exhaust gases to form a gas-steam-water mixtures at any engine operating conditions.

Let's calculate the efficiency of conversion to motion:

Standard ship:

GTU (Technically the same turbojet engine) (0.33) - Electric generator (0.9) - (we neglect losses in the transmission of electricity) - Electric motor (0.86) - Running blame (0.6)

Total maximum efficiency of such a scheme: 0.33 * 0.9 * 0.86 * 0.6 = 0.153.

In the variant of the proposed application, the turbojet engine in conjunction with an additional pipe is analogous to a water jet engine and a propulsion unit at the same time. An additional plus at high speeds in water - there is no effect of cavitation on the propeller (due to its absence).

Turbojet engine (0.3) - Water jet propulsion unit (0.6): 0.24 * 0.6 = 0.21

The parameters were selected at the maximum efficiency of individual elements (moreover, the efficiency of the water jet is taken from the device of a water jet with a propeller, clearly lower than the implementation described in this application, since it does not have a propeller, the efficiency of which is quite low in itself).

As a jet engine, for example, a ramjet engine, a pulsating jet engine, a turbojet engine, a turbofan engine, a turboprop engine, a turboshaft engine, a propfan engine, etc. can be used.

The operation of an air-jet engine includes the following processes involved (individually or in various combinations) in the implementation of the proposed technical solution:

- suction of a powerful air flow,

- the product of a powerful high-speed exhaust gas flow with high internal energy (high temperature of the exhaust gases).

According to one embodiment of the technical solution, it is proposed to use the internal energy of the thermal jet of an air-jet engine to increase engine thrust.

In one particular implementation, the engines can be installed with rotation in two planes (below the waterline), several from each side, to increase maneuverability when moving. With this solution, the propeller-steering group and the engine room as such are not necessary on the craft. The efficiency of this system can be increased significantly. The results of using engines for floating craft installed below the waterline and rotating in two planes - full compensation for rolling without the use of additional devices, compensation for rolls during turns, no negative aspects of using the rudder, "super maneuverability" of the craft, significant savings in internal space, natural integration into the engine of an expensive a separately mounted and space-saving scrubber-type device.

In another particular embodiment (for small boats - an outboard motor option), the air-jet engine is placed on the floating craft, the air-jet engine is supplied with an additional pipe, an additional pipe and engine or only an additional pipe can be submerged under water - constantly or only for a period operation - due to which the most efficient use of the energy of the thermal jet is achieved to ensure the movement of the floating craft

In the version with the immersion of the air-jet engine under water, it is envisaged to equip the engine with an additional channel for supplying air to the engine (patent No. 2661633).

In one of the private embodiments, the engine for the period out of operation can be closed with a sealed hinged cover (cap), to prevent contact of the internal elements of the engine with the seawater.

In one of the private embodiments, the exclusion of contact of the internal elements of the engine with the seawater is achieved using an additional hydraulic locking mechanism, including at least a water-filled bladder for sealing the engine. The water-filled bladder can be made of, for example, high-temperature silicone.

Alternatively, the spent gas-steam-water mixture can be cleaned from harmful impurities by the circulation method and stored in a special container and cleaned from harmful impurities. This embodiment provides for the additional supply of an additional pipe with a vane system in the area of the gas-steam-water mixture outlet, which ensures a high rotation speed and, accordingly, the effect of centrifugation of the gas-steam-water mixture. Due to the effect of centrifugation, i.e., under the influence of centrifugal force, the separation of harmful impurities is carried out.

In the latter case, an additional effect of reducing the level of harmful impurities emitted into the environment during engine operation is achieved. This particular implementation meets the requirements of the International Maritime Organization to reduce emissions of greenhouse gases and harmful impurities. Moreover, the proposed technical solution is many times cheaper and easier to implement than the currently widespread so-called. "Scrubber", since it does not require the use of additional complex special equipment, but realize the effect achieved directly during the operation of an air-jet engine.

In some embodiments, the resulting gas-steam-water mixture is additionally used to influence external objects, in particular, it is used to heat the liquid in the liquid heating tank.

In the particular case of the implementation of this solution, the additional pipe converts the intake air flow into a source of powerful vacuum for the subsequent performance of additional useful work. Examples of such an embodiment are various vacuum cleaners, gas pumping systems, etc., made using an air-jet engine and an additional pipe enclosing it.

In another case, the implementation of this solution is a powerful flow of exhaust gas with a high temperature and high speed: the additional pipe allows you to use the internal energy of the exhaust gas flow at high temperature and speed to influence external objects. Devices implemented on this principle are steam generators, fire extinguishers, sandblasting machines, boilers for heating buildings and premises, etc.

For example, in a private implementation, it is proposed to use a jet of a gas-steam-water mixture to remove debris and / or snow by means of a directed jet. In this case, a high speed, mass is directly used (the temperature of the working fluid decreases in the case of snow removal due to the use of a high degree of bypass) - a gas-steam-water mixture - for, for example, removing snow deposits or, for example, removing thickets of grass and small shrubs (in this option, the temperature of the steam-gas jet is 150-180 degrees C), due to the high temperature, not only the transformation of fresh grass into hay is achieved, but also weed pollen is destroyed, harmful insects are destroyed without harmful effects on the soil, only a layer of soil of the order of a millimeter is affected, etc. .). With such a device, it is safe to fight the current misfortune of cities and towns in Russia - the spread of Barshevik. After processing with superheated steam, it loses not only its viability, but also its dangerous (in contact) toxins decompose. (In fact, this is an analogue of a household streamer.) In the afternoon, the ferry walked around the site, the next day I collected withered grass with a rake. Such a device is mobile (wearable) and is created using a low-power turbojet engine.

In one of the private implementations, it is proposed to use a stream of a gas-steam-water mixture to influence an open flame and an ignition source in order to extinguish local and forest fires. At the same time, the high speed and mass of the working fluid - a gas-steam-water mixture (deprived of oxygen) - is directly used in order to knock down flames in the area of fire and saturate combustible materials in the application area with water and moisture (with minimization of damage to rooms located below the combustible, and with minimization of water consumption in case of forest and area fires). The possibility of extinguishing fuels and lubricants remains. For movement inside the premises affected by the fire, and for movement through the forest affected by the fire - such a device is a mobile and manual mechanism based on a low-power and small-sized turbojet engine. Its big advantage will be water saving (under NU, 27 g of water is needed to create 1 cubic meter). The approximate steam output of such a mobile fire extinguisher is 3-25 cubic meters. steam per minute. In the minimum mode, such a fire extinguisher will extinguish a couple of m. KV with a steam cube. smoldering grass, at the maximum - in a minute it will extinguish a burning small car, a standard burning kitchen with an area of 6 sq. m.

In another particular embodiment, it is proposed to use a stream of a gas-steam-water mixture for steaming building materials, for example, steaming concrete in construction.

According to one embodiment of the technical solution, it is proposed to use a high temperature of a jet of a gas-steam-water mixture for heating. For this, it is proposed to place an air-jet engine equipped with an additional pipe (with the properties of dispersing a single high-temperature gas flow into a large number of small flows) as part of a liquid heating tank for rooms and buildings, while the thermal energy of the engine jet is used to heat the liquid in the tank.

According to one embodiment of the technical solution, it is proposed to use the internal energy of the thermal jet of an air-jet engine to convert the intake air flow into a source of powerful vacuum. To do this, it is proposed to supply the air-jet engine with an additional pipe that completely encloses the engine, while the internal energy of the thermal jet of the air-jet engine converts the intake air flow into a vacuum source used, for example, for sucking in dust, pumping out gas, creating powerful compact water pumps, etc.

According to one embodiment of the technical solution, it is proposed to use a compressor similar in design to the compressor of an automobile turbine as a compressor of a turbo-jet engine. This version is characterized by economy in production and reduced noise level.

According to one embodiment of the technical solution, it is proposed to design the working section of a turbo-jet engine similar in design to the hot section of a standard automobile turbine. This version is characterized by economy in production and reduced noise level.

FIG. 1 depicts one embodiment of the present invention for increasing thrust of a jet engine (Pulsating Jet Engine). The nozzle of the pulsating air-jet engine 1 is connected to an additional pipe 2, additionally equipped with nozzles - sprayers 3 for supplying water to the inner cavity of the additional pipe. When the engine is started, air is sucked into the combustion chamber, a hot (700-1000 ° C) high-speed (up to 300 m / s) flow of exhaust gases from the engine nozzle enters an additional pipe, mixing with water sprayed by nozzles - sprayers, the water turns into steam, a gas-steam-water mixture is formed. The flow rate decreases slightly, the flow mass (with a drop in temperature) due to the evaporated water (steam) increases significantly, significantly increasing the engine thrust.

FIG. 2 depicts one embodiment of the present invention for increasing thrust of an air-jet engine. The nozzle of the turbojet engine 4 is connected to an additional pipe 2, additionally equipped with nozzles - sprayers 3 for supplying water to the inner cavity of the additional pipe. When the engine starts, the engine compressor draws air into the combustion chamber, a hot (700-1000 ° C) high-speed (up to 300 m / s) flow of exhaust gases from the engine nozzle enters an additional pipe, mixing with water sprayed by nozzles - sprayers, the water turns into steam, a gas-steam-water mixture is formed. The flow rate decreases slightly, the flow mass (with a drop in temperature) due to the evaporated water (steam) increases significantly, significantly increasing the engine thrust.

FIG. 3 shows an exemplary embodiment of the nozzle - atomizer 3 for injecting water inside the cavity of the additional pipe. The hot exhaust gas flow is indicated in FIG. 3 thin horizontal arrows, water flow into the nozzle - bold vertical arrow.

FIG. 4 depicts one of the embodiments of the present invention for increasing the thrust of a jet engine. The pulsating jet engine 1, used to move the floating craft, is located below the water level 5. The engine air intake is connected to the channel 6 for supplying air to the engine, the channel inlet is located above the water level. The engine nozzle is connected to an additional pipe 2. When the engine is started, air enters the combustion chamber through the channel, the hot (700-1000 ° C) high-speed (up to 300 m / s) flow of exhaust gases from the engine nozzle enters the additional pipe, mixing with the seawater , water turns into steam and is displaced from the additional pipe in the composition of the formed gas-steam-water mixture and non-evaporated water. The flow rate decreases slightly, the flow mass (with a drop in temperature) due to water and evaporated water (steam) increases significantly, significantly increasing the engine thrust.

FIG. 5 depicts one embodiment of the present invention for increasing thrust of a jet engine. The turbojet engine 4 used to move the craft is located below the water level 5. The engine air intake is connected to the channel 6 for supplying air to the engine, the channel outlet is located above the water level. The engine nozzle is connected to an additional pipe 2. When the engine is started, the engine compressor draws air through the channel into the combustion chamber, the hot (700-1000 ° C) high-speed (up to 300 m / s) flow of exhaust gases from the engine nozzle enters the additional pipe, mixing with seawater, water turns into steam and is displaced from the additional pipe as part of the resulting gas-steam-water mixture. The flow rate decreases slightly (this is ensured by the calculated geometric shape of the additional pipe in order to maintain pressure during the evaporation and heating of water along the entire length of the additional pipe), the flow mass (with a drop in temperature) due to water and evaporated water (steam) increases significantly, significantly increasing engine thrust.

FIG. 6 shows an exemplary embodiment of an additional hydraulic locking mechanism that ensures that the internal elements of the engine do not come into contact with seawater. The mechanism provides for equipping the end of the turbine shaft 7, facing the additional pipe, with a hydraulic brake 8, equipped with pressure supply pipes 9 with pressure-opening nipples. The mechanism is enclosed by a thin-walled casing 10, in the inner cavity 11 of which an elastic inflatable balloon 12 is located. The casing is mechanically connected to a piston 13 oriented inside the casing cavity and provided at the opposite end with a water pressure supply point 14. The mechanism operates as follows: at the moment of stopping the fuel supply to the air-jet engine is automatically triggered by the starting electric motor 15 (not shown in the drawing), which provides blowing and cooling of the air-jet engine. Pressure is applied to the place where the water pressure is supplied to the piston through an adjustable valve (not shown), the piston displaces the thin-walled casing and fills an elastic balloon with water, which seals the access to the air-jet engine. The pressure in the casing cavity is transmitted, by means of pipes equipped with nipples, to the hydraulic brake, which brakes and stops the rotation of the turbine shaft. When the fuel supply to the air-jet engine is resumed, the process is carried out in the reverse order, providing unblocking of the turbine shaft, compression of the bladder and opening of water access to the inner cavity under the casing, which provides cooling of the mechanism elements during the operation of the air-jet engine.

FIG. 7 shows one embodiment of the present invention for influencing external objects, including burning materials, containers for fuels and lubricants, snow deposits, vegetation, materials for steaming, and the like. In particular, an exemplary embodiment of the additional pipe in this embodiment is shown. Referring to FIG. 7, a turbojet engine 4, equipped with an additional pipe 2, equipped with nozzles - sprayers 3 for supplying water in the inner cavity of the additional pipe, is connected to the starting electric motor 15. The starting electric motor starts, the turbojet engine starts, the exhaust gas flow enters the additional pipe, through the nozzles into water is injected into the additional pipe, superheated steam (temperature up to 200 ° C) is formed in the additional pipe, which is used to influence external objects.

FIG. 8 depicts one of the embodiments of the present invention for heating an additional volume of liquid used for heating houses and structures, for operating snow melters and the like. The turbo-jet engine 4 is immersed in a liquid in a liquid heating tank for 16 rooms and buildings, the engine is located vertically in a "floating" state (no floats are indicated). When the engine is running, hot gases flow through an additional pipe 2, made in this case in the form of an exhaust jet splitter, which diverts the exhaust into numerous gas streams and their primary mixing with the coolant fluid. Then they float up through the coolant, giving off thermal energy to the coolant. Due to the fact that the cooling of the engine and the cooling of the engine exhaust occurs in the coolant, the efficiency is expected to be as high as possible for heat engines.

FIG. 9 depicts one embodiment of the present invention for converting an intake air flow into a vacuum source. The turbo-jet engine 4 is entirely enclosed by an enclosing additional pipe 2, equipped with an opening 17 for air injection by the compressor of the turbo-jet engine, an opening 18 for drawing in the main volume of air or gases, liquids and an exhaust opening 19. When starting a turbojet engine, the engine compressor provides air through hole 17 to ensure engine operation, the engine exhaust jet, moving in the cavity of the additional pipe, provides a high vacuum in the additional pipe, due to which the main volume of gas (or liquid) is drawn in through hole 18, exhaust removed through hole 19.

FIG. 10 depicts one embodiment of the present invention using a turbojet engine with a compressor that produces a reduced noise level. A centrifugal compressor with adjustable inlet and outlet diameters, equipped with a damper 20 with an inlet diameter adjustable according to the diaphragm principle, a damper 21 with the maximum required fixed inlet, compressor blades 22 located on the common shaft of a turbo-jet engine (for example, rectangular), damper 23 with the maximum required fixed outlet, damper 24 with an outlet diameter adjustable according to the reverse diaphragm principle. When the diameter of the inlet and outlet holes is changed, the operation of a classic rotary compressor vane is emulated.

FIG. 11 depicts one embodiment of the present invention using a turbojet engine working section that produces a reduced noise level. The work for one inter-blade space of one stage of the hot (working) part of a turbo-jet engine is schematically presented. The working part is equipped with a movable inlet flap 25, a fixed inlet flap 26, engine blades 27 (for example, rectangular in shape) located on the common shaft of a turbo-jet engine, a fixed outlet flap 28, a movable outlet flap 29. When flaps 25 and 29 rotate, the section for gas flow inlet and outlet. The gas flow entering through the adjustable section of the inlet flaps increases the pressure on the blades on its way, while the pressure on the remaining blades is lower and equal to the outlet pressure of the hot part stage, which forces the common turbine shaft to rotate. Thus, by adjusting the flow area between the inlet flaps of the hot stage and between the outlet flaps, emulation of the swivel blade of the standard hot part of a turbojet engine is carried out. By adding water (for example distilled water) to the space after the fire chambers (combustion chambers), the temperatures may drop to values that allow the use of heat-resistant stainless steel.
