这 共和国 XF-84H "雷尖叫"是一种实验性的涡轮螺旋桨飞机，源自F-84F雷电。XF-84H 由与超音速螺旋桨交联的涡轮发动机提供动力，有可能为螺旋桨驱动的飞机创造非官方的空速记录，但无法克服牙齿空气动力学缺陷，导致该计划被取消

这 共和国 XF-84H 雷鸣 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.
螺旋桨产生了连续的音爆，可以在25英里（40公里）外听到，导致地勤人员和附近居民感到恶心和头痛。噪音还干扰了飞机的无线电通信和导航系统。XF-84H被飞行员昵称为“雷鸣尖叫”，被地勤人员昵称为“强大的耳朵弹”。在1955年至1956年间，只有两架原型机被制造和测试，之后由于技术困难和空军缺乏兴趣，该计划被取消。
