And....
 
In 1957, Curtiss Wright purchased five engine test bed B-17G 44-85813 from the USAF (earlier modified by moving the cockpit aft and used to test the Wright XT-35 turboprop) and modified it further by "installing a TC18DA1 Constellation Model 1049 nacelle" that was used as the mount for the test engine, a version of the Wright Aeronautical Division Turbo Compound 18 Cyclone engine...a civil development of the R-3350. Specifically, tests were being conducted by Wright toward Power Recovery Turbine development. The tests were conducted from 1957 until 1965 or so. The B-17 had recorded 579 hours of flight time when Wright began operating the aircraft, and it ended the program with over 1581 hours logged...so over 1,000 hours of test use was made of the B-17 through that test program on the engine.
