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 hinged front part of the body.
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 armament of the aircraft with conventional weapons: machine guns and cannons.
The task of creating an aircraft and aircraft-based combat laser: improving the combat qualities of the aircraft.
The solution of these problems was achieved in a military space aircraft containing the fuselage, front and rear wings, gas turbine engines mounted on the wings and a rocket engine mounted in the rear of the fuselage, in that an aviation-based combat laser was installed on the upper part of the fuselage along its longitudinal axis which is connected by air extraction pipelines containing a control valve to at least one gas turbine engine and to a rocket engine. The rocket engine contains a turbopump assembly, two combustion chambers and a central body between them, and an air exhaust pipe is connected to the turbopump assembly. Each gas turbine engine contains a compressor, a combustion chamber, and a turbine, and an air exhaust pipe is connected to a manifold arranged behind the compressor of the gas turbine engine. Aircraft-based combat laser can be pivotally mounted on the fuselage, and vertical and horizontal guidance cylinders are attached to its front.
The solution of these problems was achieved in an aviation-based combat laser containing an optical head and an exhaust system, in that it is gasdynamic and connected by air extraction pipelines containing a control valve to a compressor of at least one gas turbine engine and with a turbo pump unit behind the turbine.
The proposed technical solution has novelty, inventive step and industrial applicability, i.e. all the criteria of the invention.
The novelty of the proposed technical solution 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 the aircraft 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.

During take-off, the fuel pump 30 is unwound by the drive 31 and the fuel is supplied through the fuel line 29 to the nozzles 24 of the combustion chamber 23, where it is ignited. The combustion products spin the turbine 25. The turbine 25 through the shafts 27 spins the compressor 22, as a result of the jet nozzle 26 creates a jet thrust for flying in dense layers of the atmosphere.
For flight at high altitudes or in space, a rocket engine 16 is launched. For this, a rocket engine 16 is launched.
When the rocket engine 16 is started from the control unit 64, signals are sent to the start valve 62. High pressure air from the ground system through the high pressure pipe 61 is supplied to the start turbine 36 and spins the TNA rotor 17. The oxidizer and fuel pressure at the outlet of the impellers of the oxidizer pumps 32 and fuel 33 is increasing. A signal is sent to open the valves 51, 56 and 58. The oxidizing agent and fuel enter the combustion chamber 31 and the gas generator 42. A signal is supplied to the ignition devices 59 and 60, the fuel mixture in the combustion chambers 18 and in the gas generator 42 are ignited. Rocket engine 16 started. The flow regulator 54 using the drive 55 carry out the regulation of its mode of operation.
When you turn off the starting rocket engine from the control unit 64, a signal is supplied to the valves 51, 56 and 58 and 65, which are closed. Then, a signal is sent to open the purge valve 62, and inert gas through the purge pipe 61 enters the fuel manifold 59 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 18 with the help of a regulator 65, which reduces the gas supply from the gas generator 42 to one of the combustion chambers 18.
For the use of laser weapons in dense layers of the atmosphere, the control valve 14 is opened and part of the compressed air (up to 20% of the total air flow through the gas turbine engine 6) is taken from each gas turbine engine 6 for pumping a laser beam in an aircraft-based combat laser 7. Applied gas-dynamic laser, as the reserves of compressed air taken from engines 6 are practically unlimited, compared with a chemical or carbon dioxide laser.
The laser beam exits through the optical head 8 and is aimed at the target using the guidance system, which is not shown in FIGS. 1 ... 5 in detail, only the executive organs of the laser beam guidance system are shown on the target. Vertical guidance is carried out by a vertical guidance hydraulic cylinder 9. When the rod of the hydraulic cylinder 9 is extended, the angle α between the axis of the aircraft and the longitudinal axis of the aircraft-based laser 7 increases. Horizontal guidance during flight in dense layers of the atmosphere is carried out by plane, mismatch of engine thrust 6 and / or aerodynamic means. When flying in space or at high altitudes, another guidance system is used, described below. When flying at high altitudes or in space, horizontal laser control is preferred. To do this, include a drive 10 that rotates the airborne laser housing at + -40 degrees.
To use an aviation-based combat laser 7 at high altitudes or in space, a gas sampling regulator 71 is opened and high-pressure and temperature gas (up to 20% of the total gas flow generated by the gas generator 42) is supplied to the aviation-based combat laser 7 via a gas sampling pipeline 70, where the energy of the gas is converted into the energy of a laser beam. The exhaust gas is discharged into the gas discharge system 15. The laser beam exits the optical head 8 and hits the target. For aiming, guidance lasers can be used, which have significantly lower power and are installed on the front wings of a military-space aircraft. (In figure 1 ... 5 laser lasers are not shown).
The application of the invention allowed:
1. To increase the combat capabilities of the aircraft through the use of powerful laser weapons and their supply with high-energy compressed air taken from one engine or all engines of a multi-engine aircraft due to the compressor (behind its last stage) or gas extraction from the turbine engine of a rocket engine with a higher energy potential.
2. To ensure the possibility of using laser weapons for a long time throughout the flight both in dense atmospheric layers to protect the aircraft from fighter and air defense missiles, and against satellites and ballistic missiles flying at high speed in space or at high altitudes.
3. To ensure that the laser beam is aimed at the target without impairing the aerodynamic qualities of the aircraft in dense layers of the atmosphere and horizontal guidance in space and at high altitudes.
