hydrodynamic piston to detect a high velocity of the delivery
envelope, in which the arming device is installed, while the
delivery envelope is traveling through the water. The detection
of high velocity travel through the water is used to unlock a
detonation explosive train which then, after an appropriate
delay, removes electrical shorting of detonation, connecting the
electrical firing circuit connection and completing the
detonation path in order to “arm” the device in order to await a
firing signal from a target detection device. By detecting water
impact and high velocity, through water, of the delivery
envelope, underwater explosive weapon deployment by aircraft
delivery is improved such that arming in response to dry land
impact is avoided and reduction in altitude and a decrease in
flight speed from conventional limits is said to be achieved.
Claim 1 is reproduced as follows:
1. A safety arming system adapted to be installed within a
delivery envelope together with an explosive device detonated in
response to a firing signal from a target detector, said system
comprising: means responsive to deployment of said delivery
envelope for establishment of an armed condition therein;
explosive path means operatively connected to the target detector
for conducting said firing signal only in said armed condition to
the explosive device; and environmental means responsive to
detection of a high velocity of the delivery envelop [sic,
envelope] during water travel for maintenance of a safe condition
during which said establishment of the armed condition is
prevented.
