Embodiment Construction

[0018] See attached Figure 1~3 , in this embodiment, the laser propulsion vehicle with the vector nozzle is powered by a 100MW ground-based laser, and can be launched from the ground into a low-earth orbit at an altitude of 200km. The aircraft is about 7m long, 3m wide, and 2m high. Its shape is similar to the US space shuttle orbiter, but the fuselage is slightly flat. The shell of the aircraft is made of high-strength aluminum-copper alloy. The propellant storage tank 2 is filled with liquid hydrogen as propellant, and the quality of liquid hydrogen accounts for about 60% to 70% of the total mass of the aircraft.

[0019] The diameter of the concave parabolic reflector 4 is about 1m, which is made of light weight and small deformation material, and the concave surface is coated with a high reflectivity film. The convex parabolic reflector 5 and the plane reflector 3 are made of materials with high reflectivity and fast heat dissipation, and a water-cooled active cooling d...

Abstract

The invention discloses a laser propulsion aircraft with vector nozzle, comprising an effective load and control instrument bay (1), a propellant storage box (2), a plane reflecting mirror (3), a concave paraboloid reflecting mirror (4), a convex paraboloid reflecting mirror (5), a high transmittance plate glass (6) and a laser propulsion engine (7). The effective load and control instrument bay is set on the head of the aircraft; said propellant storage box is set in the middle part of the aircraft and is adjacent to the effective load and control instrument bay. The concave paraboloid reflecting mirror and the convex paraboloid reflecting mirror are set on the aircraft belly on the back position, wherein the two mirrors have the same axle line and focus. The high transmittance plate glass is set below the convex paraboloid reflecting mirror and is round plate glass, and diameter thereof is slightly bigger than that of the concave paraboloid reflecting mirror, and is embedded in the shell of the aircraft belly. The plane reflecting mirror is set on the top of the concave paraboloid reflecting mirror. The invention provides a laser propulsion aircraft, which has uncorrelated propulsion direction and laser beam direction, pollution free engine and lower requirement on performance of laser incoming window of the thrust chamber, for aerospace launch and proximity space flight.

Description

technical field [0001] The invention relates to the field of aerospace laser propulsion, in particular to a laser propulsion aircraft whose beam direction is not related to the thrust direction. Background technique [0002] Laser propulsion is a new concept propulsion technology that uses the reaction force of high-temperature and high-pressure plasma flow generated by the interaction of high-energy laser and working medium to propel the aircraft forward. Compared with the traditional chemical propulsion system, the laser propulsion system has three characteristics: firstly, the aircraft does not need to carry its own energy supply system, and the energy required by the aircraft can be provided by the high-energy laser transmitted over a long distance; secondly, the energy provided by the laser radiation breaks through the combustion Due to the limitation of temperature, the specific impulse is very high; finally, the laser propulsion system has low requirements on the work...
