When primary hydraulic landing gear systems fail, Cobham's pneumatic emergency landing gear blow down systems are used to unlock, lower and relock the main landing gear structure in the down position providing a backup method of landing gear actuation.  In the event of a failure to the landing gear hydraulic system, nitrogen gas contained within the storage vessel is distributed to the landing gear through the connected manifold assembly. Cobham's emergency landing gear blow down systems set the industry standard in performance, weight and reliability.

Since 1988, Cobham has supplied the Landing Gear Blow down System for various military aircraft platforms including unmanned air vehicles, tilt rotor aircraft, trainer/light attack and rotary aircraft platforms.
