RESEARCH AIRCRAFT, XV-5A
Abstract
This report traces the development of the XV-5A research aircraft. The aircraft, though purely experimental, demonstrates the practicability of VTOL lift-fan propelled flight, combined with conversion from the VTOL mode to the CTOL mode and flight in the purely conventional mode. The XV-5A is an all- metal, twin engine, gas-propelled, subsonic, tri-fan, tricycle landing gear, VTOL/CTOL aircraft. It is 44.52 ft. long. Its wingspan is 29.83 ft., and its height to the top of the vertical stabilizer is 14.75 ft. It is powered by two J85-5B turbojet engines. Its two X353-5 wing fans(lift) are 62.5 in. in diameter. Its X373-A nose fan (pitch control, and lift) is 36 in. in diameter and is located in the nose ahead of the cockpit. All fans are operated by diverting engine exhaust gases through crossover ducts to the tip turbines on the rims of the fans. Thrust louvers below the fans control the thrust generated by the revolving fans and exhaust gases. Modifications suggested as a result of tests are being made and possible military applications of lift-fan principles of propulsion to heavy aircraft are being made.
