The principle of the Coffman starter is to use the controlled, high-pressure gas from a pyrotechnic cartridge to provide a powerful, high-torque impulse that cranks an internal combustion engine to start it. The system acts as a powerful alternative to heavier and more complex electric or inertial starters, especially in remote or extreme conditions. #science #education #medical #knowledge #mediterraneanfood #valueformoney #short #sciencefacts #sciencefiction | Life Boat Science Academy

This World War II airplane engine was hand-started with a shotgun shell. The Rolls-Royce Griffin and other massive aircraft engines used a device called a Coffman starter. Essentially, a miniature cannon that fired a blank cartridge to crank the engine. It blasted compressed gas into a piston, which turned the engine over. Why use explosives? Batteries were unreliable and electric starters were too heavy. That bang meant lift off. Mechanics had to load it like a weapon. Imagine needing ammo just
