Thrust-Vectoring Characteristic of a Novel Synthetic Jet Actuator

Abstract

The synthetic jet actuators (SJA) have large potential applications such as jet vectoring , boundary layer control, the lift and flight control , combustion control , underwater vehicles maneuvering , and micro -pump etc . A novel synthetic jet actuator is composed of a slide block , two emitting slots , and two sealed cavit ies bounded on one end by a single diaphragm . The character istics of the novel synthetic jet actuator are investigated . The novel synthetic jet actuator not only resolves the problems of pressure loading and energy inefficiency of the trad itional synthetic jet actuators, but also has thrust -vectoring characteristic that the traditional synthetic jet actuators haven’t . A primary jet vectoring using the novel synthetic jet actuator is numerically simulated , and the results show a single novel synthetic jet actuator can play both push and pull function s of vectoring the primary jet. These indicate that the novel synthetic jet actuator may potentially replace the traditional synthetic jet actuators in various applications , and also extend the ap plications of the synthetic jet actuator s to more flow control systems that can no t be implemented by the traditional synthetic jet actuators .
