摘要

A new technique for propulsion and control using Micromachined ACoustic Ejectors (MACE) is described. Past investigations have demonstrated synthetic jets using acoustic streaming. By employing micro electromechanical systems (MEMS) fabrication methods these jets have been studied at micro scales. Here the plan is to use acoustic streaming from up to six small (~ lmm x 1 mm x 30 |am) high frequency (120 kHz) Helmholtz resonators distributed about the periphery of an ejector to create thrust. An ejector is used to mix the acoustic streams with air above the craft to entrain flow and improve thrust efficiency. The use of large arrays (～1000) of acoustic ejectors is investigated for propulsion and control of micro airborne platforms.rnThis is an enabling technology to create inexpensive and mass-producible small air vehicles that are almost entirely fabricated on a single silicon wafer. The idea here is that the propulsion, sensors, control logic and perhaps even the power source might be entirely mass-produced. This would allow the deployment of a constellation of such craft to act in concert to survey volumes of space. Described here is an overview of the development of this hierarchy from small resonators, to ejectors, and the prospects of creating a flight capable Micro Air Vehicle (MAV).
