US Patent 5511044: Thrust producing apparatus
US 5511044 ยท granted 1996-04-23
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.

Claim 1
An apparatus for producing thrust, comprising in combination: a chamber; sound driver means for propagating a compression standing sound wave in the chamber, the sound wave having at least one low pressure node and at least one high pressure peak, the sound driver means producing a higher pressure in the chamber atthe high pressure peak than at the low pressure node; intake means including at least one intake port extending into the chamber at a point adjacent to the low pressure node for drawing in a fluid from exterior of the chamber; and discharge means including at least one discharge port extending into the chamber adjacent to the high pressure peak for discharging fluid from the chamber so as to create thrust.
