The Republic XF-84H "Thunderscreech" is 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 ...

xf-84h起初为f-84战斗机的一个变体，计划安装更强的 涡轮螺旋桨发动机 ，一方面让飞机获得比常规螺旋桨飞机更好的飞行速度，另一方面可以直接在航母上起飞，当然这其中也有技术探索的作用。

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.

2018年1月24日 · The Republic XF-84H Thunderscreech, developed in 1955, was an attempt to solve the problem by putting a stubby, high-speed propeller on a jet. The airplane’s nickname resulted from the fact that the prop tips went supersonic and stayed there as soon as the engine reached operating speed, making the XF-84H probably the loudest airplane ever built.

The Republic XF-84H, a joint Navy/Air Force project, was planned to combine jet-like speed with propeller-driven aircraft’s extended range, low fuel consumption, and low landing speed. The XF-84H’s altered F-84F airframe featured a T-tail and a triangular fin behind the cockpit to minimize torque from the propellers.

2024年7月22日 · Since its first flight the Republic XF-84H Thunderscreech has been known as The Loudest Aircraft in the World. The painful scream that emanated from its supersonic propeller tips sickened ground crewmen and could be heard for miles.

2024年9月26日 · 这就是 XF-84H Thunderscreech 的情况，它是美国空军原型机，搭载 最吵闹的飞机的位置一点也不令人羡慕. 这架老牌飞机已经近 70 年没有“尖叫”了（这让大多数人感到高兴），但它的故事仍然令人印象深刻。 即使在第二次世界大战期间，共和航空就已经观察到了 喷气发动机的出现 我不想被抛在后面。 在考虑了 P-47 Thunderbolt 战斗轰炸机的喷气版本后，制造商选择了全新的设计，从而诞生了我们今天所知道的 F-84 雷霆喷气机。 F-84 于 1946 年进行了 …

2022年5月16日 · XF-84 ground crews nicknamed the plane "Thunderscreech," a play on the nickname of the operation F-84 fighter bomber, because it was so loud. The propeller tips of the XF-84 traveled at Mach...

2023年2月6日 · The US Air Force has developed a number of experimental aircraft over the decades, but none was as interesting as the Republic XF-84H Thunderscreech. A derivative of the F-84 Thunderstreak, it was the “loudest aircraft ever built” – and among the most issue-riddled. As a result, it was canceled after just a handful of test flights.

2018年7月22日 · Republic came up with the XF-84H by taking the wings from an RF-84F Thunderflash and modifying the fuselage to park a 5,850 horsepower Allison XT40-A-1 turboprop engine where the turbojet engine would normally be. The T40 engine, housed behind the cockpit and driving a three-bladed 12 foot diameter Aeroproducts propeller via extension shafts ...
