Here's why:
* Propeller rotation: The right-handed propeller rotates clockwise.
* Aerodynamic force: As the propeller blades move through the air, they create a force that pushes the air backwards. This force is primarily in the direction of flight, but there is also a small component of force that acts perpendicular to the direction of flight.
* Transverse thrust: This perpendicular force is called the transverse thrust.
* Direction of transverse thrust: Due to the clockwise rotation, the transverse thrust is directed to the left, as the force is generated on the left side of the propeller blades.
Implications of transverse thrust:
* Torque effect: This transverse thrust creates a torque on the aircraft, which tends to roll it to the left. This effect is particularly noticeable during takeoff and landing.
* Yawing: The transverse thrust also contributes to yawing (turning around the vertical axis). Aircraft designers must account for these effects when designing and operating aircraft.
* Maneuvering: Pilots can use the transverse thrust to assist in maneuvering, especially during taxiing and low-speed flight.
Note: The magnitude of the transverse thrust depends on several factors, including the propeller's diameter, blade angle, rotational speed, and air density.
