ROCKET FIRE CONTROL OF XM16/XM21 ARMAMENT SUBSYSTEM FOR THE UH-1 HELICOPTER

Abstract

A rocket fire-suppression subsystem was designed and developed to arm helicopters with an increased air-to -ground defensive capability. The rocket fire control, i.e., the intervalometer, is a reliable and versatile electromechanical preset counter in which a solid-state gated relaxation- oscillator is used as a prime controller. Unique features of this subsystem are as follows: (1) All rockets are held at ground potential until ready to be fired. This completely eliminates premature and uncontrolled firing of rockets caused by electrostatic charges. (2) The firing circuit which incorporates solid-state switching is mechanically timed to prevent current flow until all switching functions are terminated. This provides a fire control with capability to perform 100,000 operating cycles with a minimum of attendant maintenance.
