What is the function of the throttle?

[EvaFitz]

The throttle refers to the control device that regulates the engine's power (thrust). In piston aircraft engines, the throttle controls the opening of the carburetor's throttle valve to regulate the cylinder's filling volume, thereby determining the engine's output power. In gas turbine engines, the throttle controls the metered fuel flow of the fuel regulator, thus determining the thrust generated by the engine. Here are the relevant details: 1. Throttle definition: The throttle, also known as the "air valve" or "throttle valve," is the control device that regulates the engine's power (thrust). 2. Working principle: The throttle position is controlled by the pilot in the cockpit through the throttle lever, which transmits the command via control system components such as pushrods, rocker arms, torque tubes, cables, pulleys, and sector gears to the carburetor or fuel regulator on the engine. In aircraft, pushing the throttle lever forward always increases power (thrust), while pulling it back decreases power (thrust).
