geometric twist — The variation along the span of the airfoil of the angle between the chord and a fixed datum. Propeller blades are designed with a twist (i.e., a higher angle at the hub than at the tip) to equalize the lift (thrust) distribution along the blade… … Aviation dictionary
Wing twist — is an aerodynamic feature added to aircraft wings to ensure that the wing tip is the last part of the wing surface to stall, for example when executing a roll or steep climb; it involves twisting the wingtip a small amount downwards in relation… … Wikipedia
blade twist — i. The undesirable variation in pitch from root to tip caused by aerodynamic loading. ii. The twist built into a propeller or rotor blade. In the case of a propeller, it is to ensure that the pitch angle at the root is greater than the tip. In… … Aviation dictionary
Stall (flight) — For other uses, see stall. In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack increases. This occurs when the critical angle of attack of the foil is exceeded. The critical angle of attack is… … Wikipedia

Rifling — refers to the helix shaped pattern in the barrel of a firearm, which imparts a spin to a projectile around its long axis. This spin serves to gyroscopically stabilize the projectile, improving its aerodynamic stability and accuracy.Rifling is… … Wikipedia
