While aircraft engines are advanced apparatuses that are self-sustaining when in operation, they often require assistance to efficiently start up. While the process may seem mysterious to the average passenger, understanding the basics of how an aircraft starts its engines can provide a fascinating insight into the marvels of aviation technology. In this blog, we will explore the essential components and processes which permit a piston-powered engine to kick off operations.
The Aircraft Starter
The aircraft starter itself serves as the catalyst for engine ignition, and similar to a car's ignition key, it is responsible for initiating the rotation of the engine's crankshaft. Once activated, the starter motor engages with the engine assembly, setting the entire starting process in motion. Put simply, the starter is an electric motor that converts electrical energy into mechanical energy, enabling the rotation of the engine's crankshaft. Starter motors are usually powered by the aircraft's onboard battery and controlled by the pilot or automated systems. When activated, the starter motor engages with the engine's flywheel, a large gear attached to the crankshaft, initiating the engine's rotation.
The engine crankshaft is a fundamental component of an aircraft engine, serving to convert the linear motion of pistons into rotational motion. This rotational motion is then harnessed by a propeller assembly for thrust generation, allowing for flight to be made possible. In order for the crankshaft to be operated, it is engaged with the starter motor through a flywheel.
Pistons play a crucial role in general engine operations, and their functionality is paramount for the starting process. Pistons are cylindrical components that move up and down inside the engine's cylinders, and they are connected to the crankshaft via connecting rods. During the starting process, the pistons are positioned in a specific arrangement to facilitate the intake, compression, combustion, and exhaust strokes required for the engine to run smoothly. Once they begin their motion during the starting process, the standard combustion cycle will begin as the engine reaches a sustainable speed.
