What does the ejection seat catapult cartridge produce to facilitate ejection?

The ejection seat catapult cartridge operates by generating pressurized gas to facilitate the rapid ejection of the seat from the aircraft. When the catapult cartridge is fired, it ignites a propellant that converts into high-pressure gas. This pressurized gas pushes the ejection seat out of the cockpit, allowing the pilot to exit the aircraft quickly and safely in an emergency situation.

The use of pressurized gas in this manner is crucial, as it provides a swift and powerful means of ejection while minimizing the weight and complexity of the ejection system compared to hydraulic or explosive systems. Additionally, the quick response of the gas-generating mechanism is vital for achieving a successful ejection while ensuring the pilot's safety at high altitudes and speeds.
