Notice that mirrored propeller and one rotated by 45° behave completely different despite looking the same.Īt 22.845° from the default angle, big propeller’s drag and lift vectors cancel out allowing it to fly straight. Angled up flies backwards, down, forward. Low α might mean the plane flights straight at high speed while high α might mean the plane is performing a narrow turn or is flying at low speed and had to increase its lift.įrom a plane building perspective, it is better to use propellers rather than wing panels as they can generate much more lift than the wing panels.Ĭhanging the angle of the propeller changes it’s drag and lift.Īt the default 0°angle the propeller drops down slowly. The higher the AOA the higher the lift generated, until stall. Is an angle between the velocity vector and an imaginary line that goes through the middle of the wing (or whole plane to simplify).
