Abstract
A pneumatic gear motor application in which a tank filled to a predetermined pressure with an inert gas such as nitrogen is heated by a heat squib device to raise the temperature of the gas and also to increase the pressure of the gas in the storage tank and be supplied through a first frangible valve to a pressure regulator for regulating an outlet pressure to a servo valve for controlling flow to and from a pneumatic motor. The pneumatic motor drives through a reduction gear mechanism that drives a worm and worm gear to actuate a control fin of a missile. The missile has four drive motors and four control fins to provide guidance for the missile.
Claims6
A pneumatic device comprising a source of pneumatic gas supply, means supplying said gas at a predetermined pressure to a manifold, servo valve means connected to said manifold for receiving said gas at said predetermined pressure and connected to a pneumatic gear motor for supplying and exhausting said gas to and from said pneumatic gear motor, a gear of said pneumatic gear motor being connected to reduction gearing that is driven by said pneumatic gear motor, and said reduction gearing being connected for driving a control fin and a position feedback potentiometer to indicate the position of the control fin.
