The XF-88B had both turbojet and turboprop engines and could taxi and take off without the turboprop operating, thus without subjecting the ground crew to the painful noise. See more ideas about fighter jets, experimental aircraft, aircraft.
The flight program lasted from June 1955 until October 1956 with the program being taken over by the McDonnell XF-88B which flew until January 1958. The design, despite its faults, did go on to serve as the framework for other related aircraft projects including the swept-wing F-model 'Thunderstreak' and the developmental minded XF-84H 'Thunderscreech' and XF-91 'Thunderceptor' forms (all detailed elsewhere on this site).

The Republic XF-84H 'Thunderscreech' was an American experimental turboprop aircraft derived from the F-84F Thunderstreak.Powered by a turbine engine that was mated to a supersonic propeller, the XF-84H had the potential of setting the unofficial air speed record for propeller-driven aircraft, but was unable to overcome aerodynamic deficiencies and engine reliability problems, resulting in the. Another novel feature was a "take-off fin" or "vortex gate" aft of the cockpit to overcome the effects of the propeller torque. It was the 1st US aircraft built with a Ram Air Turbine (RAT) which provided emergency electrical and hydraulic power in subsequent US aircraft, but provided needed power for the XF-84H when landing. The sickening noise gave the aircraft its nickname "Thunderscreech". Ginter didn't want to pay eBay prices to obtain this kit, but included it as it was made. The XF-84H development attempted to mate the existing Republic fighter airframe to a turbine engine arrangement utilizing a supersonic propeller system to produce a speedy fighting. They being the Main Track 1/72 vacuform XF-84H kit number PX-030, the Anigrand 1/72 resin XF-84H kit number AA-2059, the Execuform 1/72 XF-84H kit and finally the Collect-Aire model 1/48 resin XF-84H kit 4835. Two aircraft were built and briefly tested as noise produced by the propeller even at idle was too severe for safe ground crew activities. The Republic XF-84H was an experimental airframe based on the jet-powered, single-seat Republic F-84F Thunderstreak fighter.
Production delays on the F-84F resulted in another order of the straight-wing version.
The F-84F swept wing version was intended to be a small variation of the normal Thunderjet with only a few different parts, so it kept the basic F-84 number. The XF-84H was derived from the RF-84F as a supersonic propeller test vehicle driven by an afterburning Allison XT-40 turboprop engine. The XF-84H Thunderscreech (not its official name) was an experimental turboprop version of the F-84F. Republic XF-84H ‘Thunderscreech’ Posted on AugSeptemThe Republic XF-84H is probably one of the most disliked aircraft the United States has ever put in the air.
