The J46 engine was developed as a larger, more powerful version of Westinghouse's J34 engine, about 50% larger. Later models produced as much as 4,900 lbs with the addition of an afterburner. Essentially an enlarged version of the earlier Westinghouse J30, the J34 produced 3,000 pounds of thrust, twice as much as the J30. The following is some information on the F34 Turbojet Engine from Wikipedia: The Westinghouse J34, company designation Westinghouse 24C, was a turbojet engine developed by Westinghouse Aviation Gas Turbine Division in the late 1940s. The brochure shows some light wear but is 100% complete, fully intact and in good shape overall. This brochure is a vintage original published by Westinghouse around 1950 or so. The back cover has photos of several military airplanes powered by the Westinghouse J34 including McDonnell F2H Banshee, XF85 Goblin, XF88 Voodoo, Douglas F3D Skyknight and D-558-II Skyrocket, Lockheed XF90, Chance Vought F6U Pirate and F7U Cutlass. This brochure is nicely illustrated with an exploded view of the J34 Turbojet Engine and has information on Principle and Design of the Engine and another section titled Operation with performance characteristics and other information. I don't find a date on this brochure but I believe it was probably produced in the late 1940s or perhaps 1950 or so when these J34 Turbo Jet Engines were being produced by Westinghouse. This brochure is a four page oblong pamphlet format measuring about 7" x 4.5" per page. The F6U-1 could also be loaded with four 20 mm M3 cannon located under the nose.This is an original vintage catalog type sales brochure on the Westinghouse J34 Turbojet Engine published by the Aviation Gas Turbine Division of Westinghouse. It can fly up to 46,260 feet and can climb at a rate of 8,060 feet per minute. The aircraft has a maximum speed of 517 knots and a travel range of 1,020 nautical miles. It produces a maximum dry thrust of 3,150 lbf and an afterburning thrust of 4,224 lbf. It has a single-spool eleven-stage axial compressor, annular combustors, and a two-stage turbine.
The F6U-1 was powered by a single Westinghouse J34-WE-30A turbojet engine. The aircraft has an empty weight of 3,320 kg, a gross weight of 5,850 kg, a maximum payload of 600 kg, and a fuel tank capacity of 650 US gal. It has a wingspan of 10 meters and a wing area of 18.9 square meters. The tail height is 3.39 meters and the wheelbase is 4.8 meters. It has an external length of 11.46 meters, an external height of 2.4 meters, and a fuselage diameter of 1.2 meters. The F6U-1 was an afterburner-equipped production variant fitted with a single seat for the crew.
On June 29, 1949, the first production version designated as F6U-1 conducted its first flight. The new aircraft was fitted with an ejection seat, a newly designed vertical stabilizer, and two auxiliary fins. In 1947, a total order for thirty production aircraft was placed. On November 10, 1947, the third prototype performed its maiden flight. On October 2, 1946, the first prototype powered by a Westinghouse J34-WE-22 rated at 3,000 lbf was designated as Pirate and took to the air for the first time.
The aircraft was also fitted with Metalite on its skin which is an uncommon feature for the XF6U. It was designed with a retractable nose gear to fit better into crammed hangars. The Vought XF6U was a prototype fitted with tricycle landing gear, short and straight wings without needing to fold, and tail surfaces.
