Cobham pneumatic weapon ejection actuation systems feature cold
gas deployment with nominal pressures up to 6,000 psig.
Nitrogen or compressed air can either be stored in an
attached pressure vessel or fed from an onboard compressor.
The systems control the flow of gas allowing for the rapid
unlock of release linkages and extension of ejector pistons for
safe weapon separation from the aircraft. Pneumatic weapons
release technologies offer highly repeatable, clean ejection
capability with greatly reduced lifecycle costs due to reduced
In addition to the on weapon ejection actuation systems, Cobham
also offers complete, compact pneumatic compressor systems to
generate compressed gas for the use in the weapon ejection
Weapon ejection systems and subsystems include:
pneumatic airborne compressor systems
- Pneumatic weapons ejection valves and manifolds
- Specialty motor and motor controllers
