WebAug 31, 2024 · For a theoretical approach the propeller diameter would need to be as large as the half span of the aircraft, with both propellers mounted at mid span. … Spiral slipstream, also known as propwash, prop wash, or spiraling slipstream, is a spiral-shaped slipstream formed behind a rotating propeller on an aircraft. The most noticeable effect resulting from the formation of a spiral slipstream is the tendency to yaw nose-left at low speed and full throttle (in centerline tractor aircraft with a clockwise-rotating propeller.) This effect is caused by the slipstream acting upon the tail fin of the aircraft: The slipstream causes the air to rotate around th…
