frontfläkt

A frontfläkt, in the context of aviation, refers to a propeller or fan designed to pull an aircraft through the air. This is in contrast to a pusher propeller, which is mounted at the rear of the aircraft and pushes it forward. The front-mounted propeller is the most common configuration for propeller-driven aircraft.

The frontfläkt is typically driven by an engine, which can be a piston engine or a turbine engine. The engine's rotational power is transferred to the propeller, causing it to spin. The angled blades of the propeller then interact with the surrounding air, creating a difference in air pressure that generates thrust. This thrust is the force that propels the aircraft forward.

The design of a frontfläkt involves several key considerations, including the number of blades, their shape, and their pitch. The diameter of the propeller also plays a significant role in its efficiency and the amount of thrust it can generate. Different aircraft types and operational requirements necessitate specific propeller designs. For example, aircraft designed for high speeds often have propellers with fewer, narrower blades, while those designed for takeoff and climb performance may have larger propellers with more blades. The efficiency of a frontfläkt is also influenced by factors such as altitude and air density.
