Which type of thrust does a negative blade angle produce?

A negative blade angle produces what is known as negative thrust or reverse thrust. In the context of aircraft propulsion, the position of the blades in a propeller or rotor system significantly impacts the thrust generated.

When the blade angle is set to a negative position, it effectively changes the direction of the thrust produced by the propulsion system. Instead of pushing the aircraft forward, it redirects the airflow in a way that slows the aircraft down or pushes it backward. This principle is utilized in various scenarios, such as during landing phases where pilots may need to quickly reduce speed or achieve a reverse motion on the ground, particularly with certain aircraft types.

This functionality is crucial for aircraft operations, providing pilots with enhanced control and safety while landing or taxiing, especially in scenarios requiring immediate deceleration. Understanding the implications of blade angle adjustments is significant for effective aircraft maneuvering and operation.
