<p>An aircraft crash sensor activates an aircrew safety device upon sensing an impact in any direction to reduce the possibility of injury caused by the crash. The crash sensor includes a triaxial accelerometer (86) to sense accelerations along any vector by simultaneously sensing accelerations along three orthogonal axes. These acceleration signals are inputted to a microcontroller (80) which evaluates them, by comparing them with predetermined acceleration characteristics contained in memory (101), to determine when a crash has occurred. If so determined, an output signal is provided to operate an aircrew restraint system which secures aircrewmen in their seats to reduce injuries to them. Program modules (108) can input acceleration characteristics of a specific aircraft, armament or mission to the microcontroller to tailor operation of the restraint system to any given vehicle situation.</p> |
