Abstract
An inlet of waverider formed by two step wedge was design to investigate the application of plasma flow control on the airframe/scramjet integration design of waverider.First the performance parameters of this inlet was investigated at different condition,then the effects,such as total pressure recovery coefficient of different kinds of plasma flow control to the cases of off-design was studied.The results show that,the shock-on-lip condition can not be met at Mach numbers higher or lower the design Mach number.At Mach numbers lower than the design value,a portion of the air compressed by the shock misses the inlet and the air mass capture decreases.At Mach numbers higher than the design value,the total pressure recovery coefficient will increase.At Mach numbers lower than the design value,the effects of MHD flow control method is invalid,but the effects of virtual cowl flow control method is very well,the total pressure recovery coefficient,the compression rate and the flow coefficient of inlet will increase.At Mach numbers higher than the design value,ohmic heating flow control of quasi-DC electrical discharge will decrease total pressure recovery coefficient,but the compression rate and the flow coefficient of inlet will decrease.MHD flow control method will increase the compression rate and the flow coefficient of inlet,but the total pressure recovery coefficient will decrease sharply.
