ABSTRACT:
A device for producing thrust has a variety of uses, such as pumping liquid, compressing or blowing air, or powering an aircraft. The device has a chamber with a sound driver located therein. The sound driver creates a compression standing wave in the chamber which will have at least one low pressure node and at least two high pressure peaks. An intake port extends through the chamber and is located adjacent the low pressure node for drawing in a fluid into the chamber. A discharge port extends through the chamber and is located adjacent the high pressure peak for discharging fluid from the chamber.
