Unlike an aeroplane a boomerang spins as it moves through the air and the combination of spin … WebReturning boomerangs have a special curved shape and two or more wings that will spin to create unbalanced aerodynamic forces. These forces — sometimes called “lift" — cause …
WebNormally a boomerang is thrown with its axis of rotation at an angle to the horizontal - this provides a force to counter gravity (the component of lift is partly vertical, and partly inwards). Throwing the boomerang in the same way, it would execute a helix upwards. Better have a high ceiling on your gym.

Web26 jan. 2024 · A close approximation is to take the wing lift using the general lift formula (CL for the airfoil, wing area, angle of attack). Subtract wing lift from aircraft weight, equals amount fuselage is lifting. i.e. if aircraft weighs 10,000lbs and CL wing lift = 9500lb, then everything else (mostly fuselage - but some engine) is 500lbs.
