Projectile launched from submarine - has emergence detectors spaced along length to fire rocket when it emerges from water

摘要

The unit is used with a projectile fired through the water (14) into the air (20). It provides a launching or ignition signal (21), depending on the emergence of the projectile (11) through the surface of the water (15). There are two emergence detectors (25.1, 25.2) along the length of the projectile, staggered by a certain designed length relative to one another for controlling the time measuring unit (29) so that the ignition signal is released a given time after emerging through the surface, a time which is proportional to the difference between the reaction times of the two detectors. USE/ADVANTAGE - The ignition of the projectile can be timed with reliable accuracy with comparatively low cost in equipment. Suitable for missiles fired from submerged submarines.
