Largest propeller on an aircraft
Garuda propeller
Germany (Breslau)
The largest aeroplane propeller ever to fly was the 6.9 m (22 ft 6 in) diameter Garuda propeller, fitted to the Linke-Hofmann R II which flew in 1919 and was built in Breslau, Germany (now Wroclaw, Poland). It was driven by four 195 kW (260-hp) Mercedes engines and turned at only 545 rpm. Today, typical single-engine aircraft have propellers of roughly 2 m (6.56 ft) diameter, and turn at approximately 2,500 rpm.
