Plasma unmanned aerial vehicle

Abstract

The invention discloses a plasma unmanned aerial vehicle. First plasma exciters are distributed on the leading edges of a left wing and a right wing of the aerial vehicle; second plasma exciters are distributed in the one fourth positions of chord lines; and third plasma exciters are distributed in the maximum thickness positions. Meanwhile, a miniaturized plasma power supply is designed and integrated into the aerial vehicle, and a switch and relevant discharge parameters of the plasma power supply can be controlled through a program or in a remote control manner. When the plasma exciters start to work, the adverse pressure gradient resistance of a boundary layer is enhanced by means of plasma jet generated by the exciters, a flow field of the upper wing surface of the aerial vehicle can be controlled, and the aerodynamic characteristics of the aerial vehicle are improved; starting of the plasma exciters in the different positions is appropriately adjusted, and aerodynamic moment can be produced, so that the flight attitude of the aerial vehicle can be controlled; and the plasma aerial vehicle has the characteristics that the aerodynamic characteristics are improved, control plane flight controlling is not required, the invisibility is good and the like.

Description

technical field [0001] The invention relates to the field of aviation technology, in particular to a plasma aircraft. Background technique [0002] The attitude control of modern aircraft is mainly realized by the deflection of ailerons, elevators, and rudders, but there are some problems in the hinge mechanism that controls the deflection of the rudder surface: when the rudder surface is flying at a high angle of attack, the efficiency is low, and the control is invalid or even reversed. The controllable flight of the aircraft brings hidden dangers; the hinge mechanism, rudder surface, and hydraulic system increase the weight of the aircraft, which is not conducive to increasing the range and flight time of the aircraft; the existence of rudder surfaces and flat and vertical tails is not conducive to the stealth of the aircraft. [0003] Especially for aircraft with flying wing layout, although the distribution of aerodynamic load is better than that of conventional layout ...

[0002] The attitude control of modern aircraft is mainly realized by the deflection of ailerons, elevators, and rudders, but there are some problems in the hinge mechanism that controls the deflection of the rudder surface: when the rudder surface is flying at a high angle of attack, the efficiency is low, and the control is invalid or even reversed. The controllable flight of the aircraft brings hidden dangers; the hinge mechanism, rudder surface, and hydraulic system increase the weight of the aircraft, which is not conducive to increasing the range and flight time of the aircraft; the existence of rudder surfaces and flat and vertical tails is not conducive to the stealth of the aircraft

However, at present, the intelligent technology is immature or quite complicated, and does not meet the requirements of low cost and high range, and it is difficult to realize it in a short period of time.
