The aircraft body is made in any longitudinal section along a cubic parabola with a blunt stern and a sweep angle along the leading edge of at least 60 °. The elevator is made in the form of a pivotally mounted front of the housing.
The disadvantage is the relatively low flight speed of the aircraft M = 4 ... 6 ..

Starting propulsion systems are made in the form of gas turbine engines - gas turbine engines, and marching engines - in the form of ramjets, specifically in a patented development it is proposed to use pulsating detonation air-jet engines.
The disadvantages of this aircraft: the relatively low flight speed of the aircraft and its long acceleration to hypersonic speeds due to the low thrust of the gas turbine engine.
The tasks of creating a hypersonic aircraft: improving the combat qualities of the aircraft.
The solution to this problem was achieved in a hypersonic aircraft containing a fuselage, a nose conical part, wings, stabilizers, fuel tanks, a rocket propulsion system and pipelines for supplying fuel components to it, in that a combat laser of aviation bwsing is installed on the upper part of the fuselage along its longitudinal axis, a rocket propulsion system is installed in the rear of the fuselage and contains a turbopump assembly, with oxidizer and fuel impellers mounted on the shaft, a turbine, a starting turbine and coaxially an installed gas generator, two combustion chambers and a flat central body between them, a turbopump unit and an aircraft-based combat laser are connected by a gas sampling pipeline containing a gas flow regulator. Aircraft lasers are mounted on the wings of the aircraft. Four control jet nozzles are connected radially in the nose conical part, which are connected through regulators to an auxiliary gas generator. A regulator is installed in the gas duct of one of the combustion chambers.
The solution of these problems was achieved in an aircraft-based combat laser due to the fact that it is gas-dynamic and connected by a gas extraction pipe containing a gas flow regulator to a turbopump assembly behind the turbine.
The proposed technical solution has novelty, inventive step and industrial applicability. The novelty is confirmed by patent research, the inventive step is that a new set of essential features made it possible to obtain a new technical effect, namely, a decrease in the acceleration time of an airplane to hypersonic speeds and an increase in flight speed. Industrial applicability is due to the fact that the implementation of the invention does not require the creation of new unknown from the prior art parts and assemblies and new technologies.

The combustion chamber 21 comprises a nozzle 33 formed of two shells with a gap "A" therebetween and head of the combustion chamber 34 within which formed the outer plate 35 and inner plate 36 to the cavity "b" between them. Inside the head of the combustion chamber 34, the oxidizer nozzles 37 and the fuel nozzles 38 are installed. The oxidizer nozzles 37 communicate the cavity “B” with the internal cavity of the combustion chamber “D”, and the fuel nozzles 38 communicate the cavity “B” with the internal cavity of the combustion chamber “D”. On the outer surface of the combustion chamber 21, a fuel manifold 39 is installed, from which the fuel lines 40 extend to the lower part of the nozzle 33. An outlet from the fuel valve 41 is connected to the fuel manifold 39, the inlet of which is connected by a fuel pipe 42 to the outlet of the fuel pump impeller 25. Exit from the additional the fuel pump 27 is connected by a high pressure fuel line 43 through a flow regulator 44 having an actuator 45 and a high pressure valve 46 with a gas generator 32, specifically, with a cavity “E”.

Approximate characteristics of a hypersonic aircraft:
Flight speed M = 12
Starting weight, t 150
Propulsion of a rocket propulsion system, t 2 × 80
Speed gain time M = 12, s 120
Propellant Components for LRE
Oxidizer: oxygen
Fuel: kerosene
Combat Laser Power, MW 5
Time of continuous operation of laser weapons, s 600
Conventional armaments can be additionally installed on a hypersonic aircraft: machine guns and an aircraft gun.
When starting the rocket propulsion system 21 from the control unit 7, signals are sent to the start valve 52. High pressure air from the ground system through the high pressure pipe 51 is supplied to the start turbine 26 and untwists the TNA rotor 22. The pressure of the oxidizer and fuel at the outlet of the impellers of the oxidizer pumps 22 and fuel 23 is increasing. A signal is issued to open the valves 41, 46 and 48. The oxidizing agent and fuel enter the combustion chamber 21 and the gas generator 32. A signal is supplied to the ignition devices 49 and 50, the fuel mixture in the combustion chamber 21 and in the gas generator 32 are ignited. Starting rocket engine 4 started. The flow controller 44 using the drive 45 carry out the regulation of its mode of operation.
When you turn off the starting rocket engine from the control unit 7, a signal is supplied to the valves 41, 46 and 48 and 55, which are closed. Then, a signal is sent to open the purge valve 52, and inert gas through the purge pipe 51 enters the fuel manifold 39 and then into the cavity "A" to remove residual fuel.
At the start and acceleration of a hypersonic aircraft, the flight angles are controlled by mismatching the thrust of the combustion chambers 9 using a regulator 55, which reduces the supply of gas from the gas generator 32 to one of the combustion chambers 9. When flying in the atmosphere, the airplane is controlled by control unit 7 using actuators 6 that deflect stabilizers 4. When flying outside the atmosphere (in space) or in a rarefied atmosphere at an altitude of more than 200,000 m, an auxiliary gas generator 19 is launched (Fig. 3) and, using the regulators 20, the combustion products are fed into one from the jet nozzle control 18.
To use an aviation-based combat laser 15, a gas sampling regulator 61 is opened, and high-pressure gas and temperature gas (up to 20% of the total gas flow rate generated by the gas generator 22) is supplied to the aviation-based combat laser 15 via a gas sampling pipeline 60, where the gas energy is converted into laser beam energy. The exhaust gas is discharged into the gas discharge system 62. The laser beam exits the optical head 63.
Landing of the aircraft is carried out horizontally on the chassis 21.
The application of the invention allowed:
1. To increase the combat capabilities of the aircraft through the use of powerful laser weapons and their high-energy gas supply from the TNA of a rocket engine.
2. Increase the flight speed of a hypersonic aircraft to M = 12.
3. Raise the ceiling of the flight of the aircraft to the level of space heights, because its flight and control do not need an atmosphere.

5. Simplify the fuel supply scheme of starting and mid-flight engines.
6. Improve the reliability of hypersonic aircraft.
7. Increase the power and specific characteristics of a hypersonic aircraft,
