Abstract:
An actively deforming converging-diverging nozzle was designed using a compact piezoelectric stack actuator coupled to a micronozzle. The nozzle was designed to achieve a Mach number of 1.5 and 20%-30% change in Mach number during piezoelectric actuation. The design of the actuator is given and preliminary data is presented. A set of key parameters were identified and used to guide the design of the actuator. Supersonic flow was achieved as illustrated using micro-schlieren techniques to quantify the flow field. The new actuator is expected to provide a route towards compact broadband pulsed microjet actuation for a broad class of aerospace flow control surfaces.
