Republic XF-84H Thunderscreech – Photos & Videos

Čaj Republika XF-84H "Thunderscreech" je bio eksperimentalni turboprop avion izveden iz F-84F Thunderstreak. Napajan turbinskim motorom koji je bio parljen u supersonični propeler, XF-84H je imao potencijal da postavi nezvanični rekord brzine vazduha za avione pogonjene propelerima, ali nije uspeo da prevaziđe aerodinamičke nedostatke zuba, što je rezultiralo otkazivanjem programa

Čaj Republika XF-84H Thunderscreech was an experimental turboprop aircraft derived from the F-84F Thunderstreak. It was designed to be the world’s fastest propeller-driven aircraft, and was also one of the loudest. The XF-84H had a slender fuselage with a large, adjustable-pitch propeller in the nose and a T-tail. The propeller was driven by a turbine engine that could produce up to 5,800 horsepower. The aircraft had a top speed of over 670 mph (1,080 km/h), which was faster than the speed of sound at sea level. However, the XF-84H also had many problems, such as excessive vibration, poor handling, and engine failures.
Propeler je generisao kontinuirani zvučni bum koji se mogao čuti 25 milja (40 km) daleko, izazivajući mučninu i glavobolje među zemaljskom posadom i obližnjim stanovnicima. Buka je takođe ometala radio komunikacione i navigacione sisteme aviona. KSF-KSNUMKSH je nadimak "Thunderscreech" od strane pilota i "Mighti Ear Banger" od strane zemaljske posade. Samo dva prototipa su izgrađena i testirana između 1955 i 1956, pre nego što je program otkazan zbog tehničkih poteškoća i nedostatka interesovanja iz vazduhoplovstva.
