An apparatus for suppressing shock-induced separation of high speed airflow from a relatively low-energy boundary layer. The apparatus may include an actuator or array of actuators configured to alternately inhale and exhale fluid and positioned to alternately inhale fluid from and exhale fluid into a boundary layer of a fluid mass flowing along the wall. The actuator may be positioned to inhale fluid from a boundary layer separation bubble induced by a supersonic shock wave propagated in the fluid mass.


1. An apparatus for suppressing shock-induced separation of airflow, the apparatus comprising; an engine inlet; andan actuator configured to alternately inhale and exhale fluid, the actuator being positioned to inhale fluid from a boundary layer separation bubble induced on a wall of the inlet by a shock wave in a fluid mass flowing along the wall. 2. An apparatus as defined in claim 1 in which the actuator is positioned to direct exhaled fluid back into the boundary layer in a generally downstream exhalation direction. 3. An apparatus as defined in clai...
