Title: Fluidic direct-impact modulator accelerometer

Abstract: A fluidic accelerometer employing a direct-impact modulator for measuring celeration or velocity of a body along a specified axis of the accelerometer. This device uses two similar collinear power-input tubes directed toward each other. The axially opposing power jets from the tubes impact where the flow meets an air-bearing supported proofmass containing annular rings and produce symmetrical radial flow cones at the balance point. A change in the position of the proofmass causes the balance point to move which causes the radial flow cones to become asymmetrical and a net pressure difference is developed in the output receivers.
