=== Propeller applications ===
[[Hartzell Propeller]] developed their "Q-tip" propeller used on the [[Piper PA-42 Cheyenne]] and several other fixed-wing aircraft types by bending the blade tips back at a 90-degree angle to get the same [[thrust]] from a reduced diameter propeller disk; the reduced propeller tip speed reduces noise, according to the manufacturer.<ref name=HP/> Modern [[scimitar propeller]]s have increased [[sweepback]] at the tips, resembling a raked tip on an aircraft wing.
