Title:
ROCKET LAUNCHING SYSTEM EMPLOYING THERMAL-ACOUSTIC DETECTION FOR ROCKET IGNITION
Document Type and Number:
WIPO Patent Application WO1999006276
Kind Code:
A3
Abstract:
A rocket launching system (40) employing ignition apparatus (12, 13, 14, 18) that is used with a small rocket (10) to launch the rocket from a gun (30). The rocket is equipped with acoustic (pressure) and optical (thermal) sensors (13, 14) that detect a pressure pulse and light flash of a primer charge (35) used to fire the gun. The simultaneous detection of the pressure pulse and light flash by the sensors generates output signals that are used to complete an electrical circuit in an electronic ignition circuit (12) that activates an igniter (18) that ignites a rocket motor (16).
