Safe and Arm Device with Variable Arming Delay by Liquid Explosive.

Authors: Lee R. Hardt; DEPARTMENT OF THE NAVY WASHINGTON DC
 
Abstract: A safe and arm device, which has an explosive train interrupted by a void to establish a safe condition, has the void filled with a liquid explosive to establish an armed condition. The void may be in a manometer-like device in which the liquid explosive is motivated by fluid pressure corresponding to free-fall or other velocities. Premature arming may be prevented by forming the explosive liquid by melting a solid explosive with heat generated electrically. A selectively variable arming time delay may be provided by a variable orifice controlling the flow of the liquid explosive or by varying the temperature of the liquid to select its viscosity.
