LOCKING SYSTEM FOR FIGHTER AND TRAINER AIRCRAFT CANOPIES WITH MISTAKE PROOFING WHICH OPERATES ONLY WHEN CANOPY IS CLOSED

摘要

A mechanical system is needed to facilitate locking of the canopy of the aircraft in opened and closed positions. The system-should also ensure that the canopy does not get opened unintentionally due to vibration during fight. The system requires safety features which ensures partial locking is not stable. Also need an in-built mechanism which prohibits the lock operation itself in any partially closed condition of the canopy. The system also requires indication for locked / unlocked conditions. The system required to be simpler in design and operation, occupy less space and require less maintenance. Such a system was developed indigenously and proved successful on fighter aircraft.
