Autogyros survive just as fun aircraft, capable of very slow but safe flight and very suitable for recreational flight. Bensen-type gyros, with fixed-pitch, seesaw rotors, are –with very few exceptions– the only extant type. Concerning speed, the autogyro is limited (as the helicopter) by retreating-blade stall, and ...

WebSep 15, 2010 · In simple terms, the retreating side has lower air speeds over it when compared with the advancing side which, in consequence, requires the pitch angle to be greater on the retreating side.
