McDonnell Model 78 Marine Assault Transport - Twin Engine Jet-Rotor helicopter Military designation: XHCH-1 US NAVY MARINE Powerplant: 2x 3750eshp Allison XT56-A-2 1x 726kg thrust McDonnell 12JP20 The McDonnell Model 86 was the first helicopter specially designed for the Navy vert-rep (vertical replenishment) mission . The powerplant installation, derived from that developed for the XHRH-1, consisted of two 3750es hp Allison XT56-A-2 turbines mounted atop the fuselage and providing compressed-air to the 726kg thrust McDonnell 12JP20 pressure jet at the extremity of each rotor blade. The crew of two consisted of a pilot on the starboard side and an aft-facing winch operator to port. There was no provision for carrying loads internally. Loads were to be carried externally on a sling, in a net, or in a specially-developed pod. This pod was to be fitted with a detachable tail unit to stabilize the load in flight and with large wheels to enable it to be towed on uneven ground after it had been delivered Three XHCH-1 prototypes were ordered on 11 April, 1952, under Contract NOa(s)52-947 and a mock-up was inspected However, the programme was later cut back due to lack of funds. No prototypes were completed but a much revised mock-up was inspected on 15 and 16 November, 1956, and a full-scale rotor was tested Additional budget cuts forced the Navy to terminate the contract on 18 January, 1959, before completion of a prototype. McDonnell kept working on the Model 86 sky crane until June 1961.
