---|---|
Role | Experimental twin-rotor helicopter |
National origin | United States |
Manufacturer | McDonnell Aircraft |
First flight | August 1944 |
Number built | 1 |
The McDonnell XHJH Whirlaway was a 1940s American experimental twin-rotor helicopter designed and built by McDonnell Aircraft for the United States Navy.[1][2] It was the first successful twin-engined, twin rotor helicopter in the world.[2] The Whirlaway was the largest helicopter flown up to that time.[3]
Design and development
In 1944, the United States Navy issued a requirement for a large rescue helicopter with a capacity for ten occupants. The design was originally designated XHJD-1; shortly after flying it was re-designated the XHJH-1. The XHJH-1 first flew in August 1944, and had twin side-by-side 46 ft (14 m) rotors at the end of pylon wings which turned in opposite directions. Each rotor was powered by a 450 hp (336 kW) Pratt & Whitney R-985 engine.[2]
Variants
- XHJD-1
- Original United States Navy designation.[1]
- XHJH-1
- Designation changed before first flight.[1]
Aircraft on display
The sole XHJH-1 is held by the National Air and Space Museum.[citation needed]
