Described actuator generating a force action on a body by an air jet is based on the unusual and seemingly impossible mechanism of the jet “reflecting” from an impact on a wall. The trick is the wall is provided with perforations that allow a part of the jet to pass through. To be compensated by the remaining part, this changes its flow direction into the opposite side, forming the “reflected” jet. The phenomenon is investigated by flowfield computations.
