Republic F84H Thunderscreech

As the name implies, the Thunderscreech had some serious noise issues. The aircraft's supersonic propeller tips made it extremely loud. In fact the noise was so loud that it damaged neighboring structures and gave ground crew members headaches and nausea.

Debut of the XF84H Thunderscreech White Eagle Aerospace

The Republic XF-84H "Thunderscreech" was an American experimental turboprop aircraft derived from the F-84F Thunderstreak.

The turboprop-driven XF-84H -- a joint Air Force/Navy project -- was designed to combine the speed of jet aircraft with the long range, low fuel consumption, and low landing speed of propeller-driven aircraft.

Two XF-84H prototype aircraft were built by Republic Aviation. The use of a T-tail was required to keep the horizontal tail and elevator in clean air flow. In flight, they were destabilised by the powerful torque from the propeller, hindered by problems with the supersonic propeller blades, and plagued by engine-related glitches.

The turbojet-powered XF-84H was a variant of Republic Aviation's F-84 Thunderstreak. An Allison XT40-A-1 turboprop engine, rated at 5,850 hp, served as the power source for this novel aircraft. The XT40 drove a variable-pitch, 3-blade, 12-foot diameter propeller at 3,000 rpm. The propulsion system's thrust level was changed by varying blade.

The Loudest Airplane Ever Built The Republic XF-84H turboprop was so loud that ground crews were physically sickened by its noise. by Robert Guttman 1/24/2018 The XF-84H earned the nickname "Thunderscreech" because of the piercing howl of of it's engine during startup. (U.S. Air Force)

The XF-84H was constructed at Republic's fabled Farmingdale facility before being delivered to Edwards AFB by train. First flight was recorded on July 22nd, 1955.

The Republic XF-84H "Thunderscreech" was an 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 program.

The Republic XF-84H Thunderscreech was plagued with issues that made it dangerous to fly. Similar to aircraft equipped with the T40 - North American XA2J Super Savage and Douglas A2D Skyshark - its shafts suffered from aggressive vibrations when traveling at high speeds.

The Republic XF-84H Thunderscreech was a turboprob development of the F-84F Thunderstreak. The Thunderscreech had a supersonic propeller, and was a very loud.

Noise The XF-84H was almost certainly the loudest aircraft ever built, earning the nickname "Thunderscreech" as well as the "Mighty Ear Banger". On the ground "run ups", the prototypes could reportedly be heard 25 miles (40 km) away.

The XF-84H was a joint Air Force/Navy project created by modifying a jet-powered F-84 Thunderstreak fighter to carry the T-40 turboprop engine system. The two T-38 engines that made up the T-40.

Although the XF-84H was one of the fastest single-engine, propeller-driven aircraft ever built, it never approached supersonic speed. Due to poor performance and high maintenance requirements, the XF-84H never became operational. The XF-84H remains the loudest aircraft ever built. H/T Earl Belz. Photo credit: U.S. Air Force
