Piasecki HRP Rescuer

Piasecki Helicopter Corporation · United States · first flew 1945 · transport aircraft

The Piasecki HRP Rescuer was one of the first practical tandem-rotor helicopters to enter military service, pioneering the configuration that would later become the Piasecki/Vertol/Boeing Chinook lineage. Its curved fuselage earned it the 'flying banana' nickname.

WEFT is AircraftIQ's four-point recognition method — how it works.

Spot it by:

The banana-shaped fuselage curving upward at the tail end to raise the rear rotor clear of the forward one, tandem rotors without a tail rotor, and the fabric-covered construction of early examples are the primary identification features.

History

First flown in March 1945, the HRP-1 was ordered by the US Navy and Coast Guard. The tandem rotor layout overcame the torque limitations of single-rotor designs, allowing a larger and heavier fuselage. It demonstrated the viability of tandem-rotor heavy-lift helicopters.

Variants

The HRP-1 Rescuer had fabric covering over a steel-tube frame; the HRP-2 introduced an all-metal fuselage. The US Navy and Marine Corps both operated the type. A small number also served with the USAF.

Where you'll see it

Operated by the US Navy, Coast Guard, and Marine Corps from the late 1940s into the mid-1950s, primarily for utility, rescue, and experimental operations. The type laid the groundwork for Piasecki's later and more capable tandem-rotor helicopters.
