The accelerator is coupled to the acceleration pipe (3) for acceleration, perpendicular start. The device is also applicable in water for ship propulsion in a reactive manner, without rotational parts, high surfaces and low characteristic speeds.

Description

Technical field

The technical solution concerns air blowers or other means of transport.

BACKGROUND OF THE INVENTION

Propulsion of air vehicles uses reactive engines in different versions according to category and size. The demands for high tractive power are solved mostly by using turbochargers in the design of by-pass turbines with a larger cross-section than the turbocompressor and the combustion turbine itself. The outflow of the combustion gases is thus mixed with the air flow into a larger discharge volume and thus with a higher drive efficiency.

The essence of the technical solution

Extending and favoring the advantages of turbochargers used in aviation to date is solved by a technical solution based on the induction air flow from the outlets in the rear part of the pressure plates, which form a system connected by a pipeline which is pressurized from the exhaust of internal combustion engines, turbines or other pressure sources such as compressors, rotary blowers or pumps.

The pressure plates are formed by joining two casing sheets thermally insulated by thermal insulation with internal joints and a shape that creates distribution channels for a continuous flow of the pressure medium into the outlet slots. Inner joints are formed by resistance welding or sintering of powdered materials when the application is of a high temperature nature.

The pressure plate interconnecting piping can also be connected in parallel to an accelerating pressure source, an accelerating piping that has different forms in various applications such as a pneumatic accumulator or an auxiliary power unit (APU), which is used to start turbines. The high short-term power allows a quick start or a perpendicular start when used in a convertoplane.

The slotted induction blower with its technical solution enables to use the reactive drive on a wider scale even at lower speeds and can use a larger range of elements as a source of pressure.

EXAMPLES

An efficient use of the slot induction blower is to drive amphibious vehicles (flying vehicles).

An example is a flying motor with a four-stroke engine M, where a small drive width and mechanical transmission of the engine power to the pusher is expedient. The motorbike is equipped with supporting surfaces above the level of standard motor vehicles for starting on the road. The drive is a slotted induction blower on the sides of the rear wheel in the shape of a rectangle from a set of pressure plates 1 with a height greater than the width of the pipe 2, which is connected to the exhaust 4 of the four-stroke internal combustion engine. The resulting pusher unit does not contain rotating parts and no mechanical gears and reducers to the pusher or auxiliary motor are required. The connection is through a two-way valve so that it is possible to convert exhaust gas from normal operation. The connection to the slot inductive blower generates a thrust which corresponds to a propeller pressure of the described surface area coinciding with a lattice area formed from the pressure plates 1 for a given engine power. At start-up it is possible to combine the thrust of the drive unit with the wheeled output by means of the acceleration accumulator A of the pressure by connecting the acceleration line 3, for a quick and short start. The exhaust pressure can take full engine M power during flight and must match the gas outlet velocity in the outlet slot 6, which is adjusted according to the engine M by the outlet slot control 5.

The pressure plates 1 are made of a casing 9 which forms their surface and which is interconnected by internal joints 8 e.g. resistive welds.

Another embodiment of the invention is the use of a slot inductive blower in a convertoplane for perpendicular take-off and landing. The propulsion units are easily tilted by 90 ° to perpendicular buoyancy. Short-term extreme power is using acceleration source A, which in parallel powers the drive unit with acceleration

SK60-2016 U1 via line 3 and at the same time feeds the internal combustion engine M by intensive supercharging In extreme cases, electric heating of the housing 9 is possible from an electrical storage source (supercapacitor) and thus achieves up to multiples of nominal power of the drive units. tilting the drive units to horizontal thrust (pressure).

Another embodiment of the invention is the use of a slot induction blower for the reactive propulsion of ships, especially river-driven vessels. You ^and functional ka ° grille flatness of the pressure plates 1 will increase the efficiency of the drive especially when navigating upstream. Propulsion units can also be placed on the side of the ship with adequate hydrodynamic effect by sucking water from the front. The essence of the effect is the relatively low characteristic reaction rate of water at a low discharge volume and a high but narrowly guided discharge rate. The temperature of the exhaust gases or vapors inside the pressure plates 1 is maintained by thermal insulation 7. If the pressure medium is water, thermal insulation 7 is not necessary. The dimension of the outlet slots 6 below 1 mm causes a decrease in the exit velocity v at increased internal pressure and reaction force. The velocity reduced in vr is the velocity produced by the inductive entrainment of ambient air or water into a proportionally increased flow cross section and thus a proportionally higher reactive force when the velocity decreases to the velocity reduced in vr. The speed of movement in a vehicle, ship or aircraft can thus be in a wide range, even for low-speed means.
