Fluidic proximity sensing apparatus for use with a linear induction motor car. The apparatus is comprised of a floating sensor head in operative combination with a dual flapper valve which forms two air gaps. A change in the proximity of the sensor head to a track surface is converted to a dimensional variation in the air gaps, which in turn is sensed by fluidic oscillators.

Fluidic proximity sensor and related process

A rotary pneumatic motor provides initial acceleration and starting of a rapid firing gatling-type gun, and also provides motive drive power for the gun in another embodiment. Upon reaching operating speed, a fluidic control system modulates application of a disc brake and/or meters fluid flow to the rotary motor to maintain a constant preselected firing rate. After completion of gun firing, the rotary motor briefly drives the gun to clear the chambers of ammunition.
