What is the Fixed Pitch Rpm & How does it work?

The fixed-pitch propeller is a type of aircraft propeller that has blades with a constant pitch angle, meaning the blade angle relative to the plane of rotation remains unchanged. This design simplifies the propulsion system but limits its efficiency across different flight conditions.

The RPM (Revolutions Per Minute) of a fixed-pitch propeller at cruise speed is crucial for optimizing engine performance and fuel efficiency. It is influenced by factors such as airspeed, altitude, and engine power settings.

RPM = \frac{Power}{Speed \times Torque}

RPM = Revolutions Per Minute
Power = Engine power in horsepower (HP)
Speed = Airspeed in knots
Torque = Propeller torque in pound-feet (lb-ft)
