ABSTRACT:
A sonobuoy suspension system is disclosed wherein a spring motor having a substantially constant output torque is mounted within an upper sonobouy unit secured to a buoyant flotation member. Formed from a coiled band, constant force extension spring wound in opposite directions about a pair of rotatable drums so that the spring is extended tangentially therebetween, the motor is coupled to a lower sensor unit by a non-compliant suspension cable for supporting the sensor unit at a predetermined underwater depth substantially isolated from the wave affecting the upper unit and flotation member.
