- bigiain 14y agoRotor craft are limited by a combination of needing the advancing rotor blade stay under mach1[1], and having the retreating blade still moving fast enough[2] still be able to create lift. Flying much faster then 200kmh usually needs tricks like going to more than 2 blades, and exceeding 500knh (where the advancing blade needs to exceed mach1 if the retreating blade isn't moving backwards through the air) required very expensive blades (and becomes outrageously noisy) [1] 'cause breaking the sound barrier along parts but not all of the advancing blade makes things complicated and expensive. [2] and keep in mind this is backwards, relative to the body of the helicopter.autogyro
- spatten 14y agoI think it's actually about the same speed as a Cessna or something similar flies, which is pretty impressive if you ask me.
