They Made a Supersonic Propeller Plane

About this video

Max discusses the Republic XF-84H ThunderScreech, an experimental aircraft built by Skunk Works with a supersonic propeller. He explains that the aircraft was designed to be a supersonic fighter driven by a propeller, but according to Max, it had severe problems including extreme noise audible from 25 miles away, structural vibrations that damaged the control tower at Edwards Air Force Base, and chronic instability and mechanical failures. Max notes that while the program failed, it contributed to the development of the ram air turbine used in modern aircraft.

Key takeaways

• Max explains that the XF-84H had a 12-foot supersonic propeller with blade tips traveling at 1.18 Mach, creating sonic booms that could be heard 25 miles away and shook the Edwards Air Force Base control tower
• Max recounts that test pilot Lynn Hendrix flew it once and refused to fly it again due to instability and ‘snaking,’ and that test pilot Hank Beard made 11 flights with 10 emergency landings
• Max argues that despite the program’s failure, the development of the ram air turbine from this project has saved lives in modern commercial and military aircraft
