The Convair P6Y (factory designation Model 24) was a flying boat designed in the 1950s by the manufacturer Convair .
history
In the mid-1950s, the US Navy planned the development of a seaworthy flying boat that would be used for submarine hunting using a diving sonar . The tender published by the Bureau of Aeronautics at the beginning of 1956 called for an open ocean seaplane to be capable of landing and take-off in the open sea up to a wave height of 12 ft. (3.60 m), which corresponds to strength 5 on the sea state scale .
The proposal submitted by Convair competed with designs by Grumman ( Grumman G-132 ) and Martin ( Martin P7M ). The structural design envisaged a three-engine high-decker with 3700 hp Wright R-3350 . The wings should be arranged on pylons high above the fuselage. Also unusual was the large vertical stabilizer, which, including the dorsal fin, reached up to the middle of the aircraft. In order to achieve the low speed of around 35 to 40 mph (56 to 64 km / h) required for landings in rough seas, an elaborate boundary layer control was planned. The compressed air required for this was to be provided by two General Electric J85 jet engines installed in the middle engine nacelle . In take-off and landing mode, the outlets of the J85 should be rotated so that the air could flow over the flaps and ailerons, while in normal flight the jet engines generated additional thrust for level flight.
In February, Convair was announced as the winner of the competition and the construction of two XP6Y-1 prototypes was commissioned. The intended serial numbers were 147207/147207. However, the US Navy stopped financing before construction began. One reason for this was certainly the decision made in 1958/59 to start developing the land-based Lockheed P3V . Interestingly, some of the engineering concepts envisaged for the P6Y were later applied to the Shin Meiwa PS-1 . Aircraft comparable to the XP6Y are also: Beriev Be-6 , Consolidated PBY and Martin P5M .
