Chase XC-123A
The Chase XC-123A was an experimental transport aircraft developed by Chase Aircraft. The first jet-powered transport built for the United States Air Force, it was intended for use as a high-speed transport for high-priority cargo and personnel. The XC-123A was determined to have insufficient advantages over existing types in service, and did not go into production. The sole prototype was converted into the piston-powered Stroukoff YC-123D to evaulate boundary layer control systems; following the conclusion of testing, it was sold onto the civilian market, and still exists, having been converted to turboprop power.
==Design and development==
In the late 1940s, Chase Aircraft had developed the XG-20, the largest glider ever built in the United States.〔Sergievsky et al. 1998, p.128〕 By the time it was ready for operations, however, U.S. military doctrine had been altered to remove the requirement for the use of transport gliders in combat.〔Mitchell 1992, p.164.〕
However, the XG-20's aircraft had been designed to allow for the easy installation of powerplants, and Chase modified the two prototypes into powered aircraft, one becoming the XC-123, with twin piston engines.〔Adcock 1992, p.4.〕 The second XG-20, however, was taken in hand for a more radical reconfiguration, being fitted with two twin-jet engine pods, of the type used by the Convair B-36 and Boeing B-47 bombers, to become the XC-123A.〔 As there was no provision for housing fuel in the former glider's wings, fuel tanks were installed underneath the cabin floor.〔
