Piasecki H-21 Shawnee
Design & Development
Piasecki Helicopter designed and successfully sold to the US Navy a series of tandem rotor helicopters, starting with the HRP-1 of 1944. The HRP-1 was nicknamed the "flying banana" because of the upward angle of the aft fuselage that ensured the large rotors did not hit each other in flight. The name would later be applied to other Piasecki helicopters of similar design, including the H-21.
In 1949, Piasecki provided the H-21 Workhorse to the USAF, which was an improved, all-metal derivative of the HRP-1.
