Description

The invention relates to the aviation industry and may find application in the creation of a new type of aircraft that does not have an analogue.

The present invention improves a passenger aircraft in which the fuselage cross section is round.

The disadvantages of this aircraft are: the fuselage has a large area, but does not perform the lifting force function, and the wings, performing the lifting force function due to the wing profile and angle of attack, are not effective, as a result of which the wingspan reaches large sizes. On the wings, the lifting force starts to work at a speed of 250 km / h. And this is a dangerous speed, which often leads to an accident and even disaster.

The design of the aircraft is not rational, metal-intensive, and an alternative to this has not been found so far. The fuselage section is too large in diameter, this leads to significant drag and loss of speed.

The “ramjet engine” is still not in demand, since it has large dimensions, so it cannot be put on the wing, it cannot be combined with a modern aircraft, and this engine would increase speed and increase efficiency.

The aim of the present invention is to remedy these disadvantages, i.e. elimination of drag, which entails the elimination of the sound barrier.

Creation of a new type of lifting force and due to this, wings are eliminated. Take-off and landing speed, i.e. take-off and landing are carried out at zero speed from one point and to one point, at a low altitude and on a small site, and due to this, the runway is eliminated. The landing gear is removed and landing is carried out on small wheels, like in a helicopter, which are designed for parking.

This goal is achieved by the fact that the body of the ramjet engine is converted into a fuselage of an airbus, which is a rectangular tube, on the lower and upper shelves of which are installed flat passenger lounges with lowered ceilings and passenger passages, in the height of a person, through which passengers pass to their seats . See invention patent No. 2297951 "Aircraft with a flat fuselage." Priority of the invention August 31, 2005. Author Sustin I.F.

The upper and lower passenger cabins are interconnected by vertical side walls and a central wall passing along the central axis of the two passenger cabins, thereby creating an airbus fuselage, which includes two internal cavities in the rear of which turbojet engines are installed, which create due to air intake high-speed air flow, and according to the law of physics (Bernoulli's law of 1700-1782, “The flow of liquid and gas”), the pressure in the gas (air) stream decreases.

As a result of this, the airbus cavity is transformed into the airship cavity and performs a lift function superior to the lift function on the wing profile. In the nasal part of the fuselage cavity, in vertical and horizontal planes, rotary shutters are installed, designed to control an airbus at the time of take-off, landing and in flight. These dampers are located in high-speed air flow, so the aircraft is controlled even at minimum speed. The same rotary flaps are installed in the rear of the fuselage cavity and taken together create effective control of the aircraft and can withstand the side wind. In the nose of the fuselage, the flat passenger cabins have an arrow-shaped shape in plan and from the lower compartment, a pilot cabin is installed on the central axis. In the rear part of the fuselage, under the lower plane, "Flow-forced air-propelled engines" are installed. Patent for invention No. 2300006. Priority of the invention August 31, 2005.

This engine is connected through an outlet to the side of the turbojet engine between the compressor and the turbine. The compressor has increased performance, which provides air to the turbine and the "Forced forced-air jet engine." Since this engine does not have a rotor, because he doesn’t need it, the temperature in it is maximized, he works in the mode of a constantly operating afterburner and even more, because afterburner is switched on for a short time. A gentle temperature is applied to the turbine, which protects the turbine blades from destruction. This engine, due to the high temperature, accelerates the aircraft, after which the fuselage cavity is switched on as a ramjet engine, and all other engines are turned off and on before landing.

See the invention “Mechanized casing of a continuous-flow jet engine”. Patent for invention No. 2318699. Priority August 31, 2005. Author Sustin I.F.

This engine is an analog of the above. The jet nozzle is blocked for it in order to direct the gas-air flow through the outlet under the lower plane of the fuselage to create an air cushion, which creates additional lifting force needed at the time of take-off and landing, and slows down the speed to make the plane take off from one point at a low height and landing on one point without touching the ground until it is fully landing. The aircraft has small wheels or arches, like a helicopter, for parking. Chassis and wings are eliminated, as well as the runway, as in this case, it is not needed. See the invention “Plane with flat hovercraft”. The priority was set on August 31, 2005. Application No. 2005127412/11.

The parking of this aircraft is located not far from the city or even in the city itself, through which the route of public transport passes. This aircraft is not hindered by bad weather, as he has take-off and landing speed equal to the speed of a pedestrian, he is not afraid of snow drifts, as well as a side wind, he has devices (see below for a description of the operation of the dampers) that can withstand a side wind.

Due to air intake, turbojet engines create high-speed air flow in the cavity of the airbus fuselage, ahead of the speed of the aircraft, thereby not only eliminating the formation of dense air mass in front of the nose of the fuselage, but also creating reduced pressure in front of the aircraft, which entails not only completely eliminating the frontal resistance and sound barrier, but also creates additional force, pulling the plane into this low pressure zone formed in front of the plane. And when a ramjet engine is turned on and since it is more efficient and besides, work occurs throughout the entire volume of the fuselage cavity, since the entire volume of the fuselage cavity is a ramjet engine, the speed flow and rarefaction in the fuselage cavity and in front of it increases many times . Thus, the aircraft flies in a rarefied air atmosphere, and the higher the speed of the aircraft due to air intake, the more rarefied atmosphere is created in front of the nose of the fuselage, this factor will dramatically change the speed of the aircraft in the direction of increase. In addition, the load on the aircraft body is reduced, which means that the resource of the aircraft body can be increased and, moreover, the aircraft can be made lighter. Due to the increase in thrust, first on a turbojet engine, and then on a ram engine, the air flow rate in the cavity of the airbus fuselage increases and due to this, the lift increases, the airbus acquires the properties of an airship and is pushed into the upper atmosphere spontaneously. At the time of take-off, the flaps installed in the front of the fuselage can partially block the fuselage cavity, which will cause a vacuum to form inside the cavity and thereby increase the airship effect and, in addition, partial blocking of the air flow will limit the aircraft’s forward thrust and, therefore, the aircraft will take off vertically .

Airbus includes the fuselage body of Fig. 1, which is a rectangular tube, on the lower and upper planes of which are installed flat passenger cabins 1 with lowered ceilings, forming an internal cavity 3, inside of which, in the rear of the fuselage, turbojet engines 4 are installed , and on the side they are connected to the flow-forced air-jet engines 7.

Air duct 5 is an air-jet engine, the thrust vector of which is directed towards the flight. Passenger passages 6 allow passengers to go to full height, and bend down to the seats 8. In Fig.6, the bomber-missile carrier is a side view, in Fig.7 is a front view, the compartments are loaded with missiles, in Fig.8 is a plan view.

At the moment when the airbus is ready for flight, the boarding of passengers begins. Passengers pass through the passenger passages 6 to their full height, and they bend down to their seats, since the ceilings in the passenger compartment 1 are lowered in order to reduce drag and, thus, increase speed. The round section of the fuselage of a conventional aircraft is converted into thin, separate passenger cabins 1, which are dispersed on the lower and upper planes of a rectangular pipe, form an internal cavity 3, in the rear of which turbojet engines 4 are installed, which create high-speed air flow due to air intake and according to the law physicists (Bernoulli's law) lower the pressure, as a result of which the fuselage gets the airship effect and is pushed into the upper atmosphere, without wasting energy on it. And if you also create an obstacle to the free intake of air using the rotary shutters 14, then you can get a vacuum in the cavity 3. In this case, the plane will quickly fly up.

Cavity 3 performs four functions: due to the high-speed air flow - the effect of the airship.

Cavity 3 meets the necessary parameters that allow you to include in the operation of "ramjet engine", and this is a high-speed engine and more economical.

Due to air intake in front of the nose of the fuselage, low atmospheric pressure is formed, which eliminates the compaction of the air mass in front of the nose of the fuselage, creates reduced pressure and thereby pulls the aircraft forward, performing the function of a propulsor together with jet propulsion coming from turbojet engines 4, and also provides breaking the sound barrier.

The round fuselage section of a conventional aircraft is dispersed along the planes of a rectangular tube, converted into flat, thin passenger cabins, which allows to reduce drag and increase speed.

A rectangular pipe allows you to rationally place the necessary devices inside, for example, jet engines 4 and 7, rotary shutters 14, steering wheels 10 and 11, etc.

Before takeoff, turbojet engines 4 are switched on, on which axial compressors of increased productivity are able to provide engines 4 and 7 with air. Engines 7 are switched off at the time of takeoff. Air with fuel is supplied through branch 5 and a jet thrust towards flight is created. Turbojet engines 4 take air through the cavity 3, thereby creating high-speed air flow in the cavity 3, lower the pressure, and the cavity 3 is converted into an airship. And so that the airbus (airplane) does not enter flight mode ahead of time, air and fuel are fed to branches 5 to create jet thrust directed towards the flight, thereby creating an air-cushion under the lower plane of the airbus fuselage, which rises to a certain height. Jet thrust on engines 5 is weakened and the airbus enters flight mode. At this time, the engines 7 are turned on, which allows you to quickly gain speed. The lower plane of the fuselage has a heat-resistant coating (for example, Carbon Fiber, developed by Samara scientists at the Tupolev Design Bureau for the Russian space shuttle). Small wings can be mounted on the fuselage for in-flight control.

Figure 5 in the cavity 3 installed in-line forced-air jet engines 7, with which the acceleration is carried out to 2000 km, after which the cavity 3 begins to function as a "ramjet engine" (ramjet). Turbojet engines 4 are turned off, and therefore engines 7 are also turned off, shutters 8 are closed, and then the plane flies on the ramjet until the end of the flight. Before landing, the previous scheme is restored.

Engines 7 meet the requirements of aerodynamics and they easily withstand the high-pressure air flow in the idle position during the flight.

In Fig.9 - an airplane with one passenger cabin located on the lower plane of a rectangular pipe.

In the rear part, rotary shutters are installed that perform the functions of the elevator 10 and rudder 11.

The bow also includes rotary shutters 12 and 13, designed to control the bow individually. These rudders are in high-speed air flow, so they are able to effectively control the aircraft.

This aircraft is unique in that its flight speed can vary in a wide range, from zero, that is, it can hover in place, to extremely high, since its design is a flying “ramjet engine”, which, without meeting frontal drag, flies in a rarefied atmosphere. This aircraft is able to greatly increase the speed limit in aviation.

This aircraft is also unique in that it can fly at high speed at low altitude, and since it uses a ramjet engine, you can not be afraid that a bird can get into the engine and thereby a catastrophe occurs, which means that it can be used and for military purposes and not to be seen for radars. Using the aircraft for military purposes, the passenger cabin in the aircraft can be eliminated by replacing it with a thin plane.

This aircraft, Fig.9, does not need a runway and a ramp. He can make a landing anywhere. Passengers enter the cabin like a bus, from the floor of the site, the ceilings are high. This aircraft is used where there is no transport structure, for example, in the tundra, taiga, extreme north, on short airlines, without pursuing high speed. It performs the function of a flying bus.

The advantage of this aircraft, Fig.9, also lies in the fact that the absence of a runway and low speed during takeoff and landing make it possible to operate in deep fog, and orientation is carried out only by satellite navigation system, such as GLONAS. Also, the ability to hang on the spot makes it possible to use it in rescue operations, and the airship’s properties make the aircraft very load-bearing and make it possible to use it in other areas, for example, in construction, lifting heavy structures.

This aircraft, Fig. 9, will create an analogy to railway transport and competition to the sea, help to master the coast of the Arctic Ocean and lay a new air route - St. Petersburg - Chukotka - Alaska.
