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. . Its sound was measured to be at approximately 200 dB and was so loud that it could be heard almost 25 miles away. A naval development of the bomber is designated Tu-142. On the ground "run. The XF-84H development attempted to mate the existing Republic fighter airframe to a turbine engine arrangement utilizing a supersonic propeller system to produce a speedy fighting platform as an. Unlike standard propellers that turn at subsonic speeds, the outer 24–30 inches (61–76 cm) of the blades on the XF-84H's propeller traveled faster than the speed of sound even at idle thrust, producing a continuous visible sonic boom that radiated laterally from the propellers for hundreds of yards. This was an Air combat aircraft; although it didn’t take part in any, it still made history because of the loudest sound. One of the ways to solve it was the equipment of aircraft turboprop engines - more economical than turbojet. S. Sign In.
