Suspension device for linking a sight means to a vehicle's structure, particularly for a rotorcraft

摘要

The infra-red sensor mounting for a combat helicopter has a controllable locking system (20) to selectively prevent relative movement of the sections (5,6) of the sensor mounting. The sections are formed as plates attached to the helicopter airframe and the sensor. The plates are connected by suspension torsion bars to allow damped relative movement between the plates when not locked. The lock can be formed by multiple releasable tongue and groove joints.
