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

reportActive / Technical Report | Accession Number: AD0632838 | Open PDF

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.
