Aircraft Control Characteristics Control Performance Investigation of Single Pulse Plasma Synthetic Jet
摘要
Abstract
The high-speed plasma jet generated by arc discharge in plasma synthetic jet(PSJ)actuator can effectively improve the control efficiency and accuracy of aircraft.It can optimize the problems of long response time,large miss distance and low efficiency in traditional flight control technology.In this paper,the single pulse jet performance of PSJ actuator has been studied based on the phenomenological model.It is found that increasing the deposition energy can effectively improve the flow characteristics of the jet,and the peak velocity,duration and impulse of the jet are significantly improved.The increase of flight altitude will have a negative impact on the flow characteristics of the jet.When the flight altitude increases from 0 to 20km,the peak velocity of the jet decreases by about 20%,but the duration of the jet remains basically unchanged.The increase of the flight speed will reduce the peak velocity of the jet and prolong the duration of the jet,so that the impulse generated by the single pulse jet is significantly increased.The deflection rate of the aircraft under PSJ control is always higher than that of the traditional aerodynamic surface.Although the increase in flight altitude causes the pitch rate at 20km to be only about 4%of that at 0,the effectiveness parameter is as high as 12.66.The study results provide references for realizing high effective attitude control of aircraft.关键词
