Abstract:

The basic high performance helicopter HPH will cruise at 175 knots with a payload of 2 tons. Maximum speed with this payload is 182 knots, and the aircraft is capable of a maximum speed without payload of 195 knots 224 mph. Minimum design ferry range capability was set at 1600 nautical miles, but a value in excess of 2000 nautical miles was achieved with a vertical takeoff. Higher speed and payload capabilities were achieved with various modifications of the basic aircraft. The HPH is inherently stable in forward flight, meeting Military specification flying qualities requirements without artificial stabilization of any kind. The high performance helicopter incorporates a number of basic advances.
