This Is How Engines Started in the 1930s This is a cartridge starter, also known as a Coffman starter or shotgun starter. It’s a historical engine-starting system used in aircraft, tanks, and tractors during the 1930s and 1940s. Instead of relying on heavy or unreliable electric starters, a small explosive cartridge was fired to generate the mechanical force needed to crank the engine and start it. #EngineeringHistory #VintageTechnology #MechanicalInnovation #techno #technology credits: @ Patch
