ABSTRACT:
A means for interfacing between low pressure, low flow fluidic circuits and he high pressure, high flow input requirements of fluidic digital thrusters to control the roll, pitch or yaw rate of missiles is provided. Input pressures from the fluidic circuitry cause a fluidic digital amplifier to go to one of its two stable states. The output from the digital amplifier operates one piston in the interface means, causing it to close off a digital thruster control port. The same output is ported to the opposite side of the other interface means piston, causing it to unblock the other digital thruster control port. Blocking of the first control port causes the digital thruster to switch to either a left or right output leg to initiate a corrective thrust. The pistons are interlocked so that only one piston can be extended to cover a given control port at any time.
