The Bell X-1 (Bell Model 44) is a rocket engine–powered aircraft, designated originally as the XS-1, and was a joint National Advisory Committee for Aeronautics – U.S. Army Air Forces – U.S. Air Force supersonic research project built by Bell Aircraft.

Bell X-1, U.S. rocket-powered supersonic research airplane built by Bell Aircraft Corporation, the first aircraft to exceed the speed of sound in level flight.

On October 14, 1947, the Bell X-1 became the first airplane to fly faster than the speed of sound. Piloted by U.S. Air Force Capt. Charles E. "Chuck" Yeager, the X-1 reached a speed of 1,127 kilometers (700 miles) per hour, Mach 1.06, at an altitude of 13,000 meters (43,000 feet).

2022年10月13日 · Seventy-five years ago, on October 14, 1947, the Bell X-1 Glamorous Glennis, piloted by U.S. Air Force Captain Charles E. “Chuck” Yeager, became the first airplane to fly faster than the speed of sound (Mach 1). The experimental purpose-built aircraft reached 1,127 kilometers (700 miles) per hour (Mach 1.06).

2014年2月28日 · Aircraft had begun to experience both subsonic and supersonic airflow over their wings. This created a range of undesirable characteristics—compressibility, increased drag, trim changes, severe turbulence, and loss of control effectiveness.

The first of the rocket-powered research aircraft, the X-1 (originally designated the XS-1), was a bullet-shaped airplane that was built by the Bell Aircraft Company for the US Air Force and the National Advisory Committee for Aeronautics (NACA).

The Bell X-1 is one of the most significant test aircraft in history since it was the first plane to conclusively break the sound barrier. The X-1 project began in 1944 when the US Army Air Force (USAAF) and the National Advisory Committee for Aeronautics (NACA) agreed on a joint program to investigate the possibility of supersonic flight.

2000年7月30日 · Starting with the first U.S. purpose-built X-plane, the Bell X-1 in 1946, and culminating in the still-to-be surpassed Mach 6+ X-15, these high-speed aircraft were helped along their paths to...

Powered flights began in Dec. of the same year and on Oct. 14 1947 the first X-1, piloted by Capt. Charles E. Yeager, became the first aeroplane to exceed the speed of sound, reaching 670 mph or Mach 1.015 at an altitude of 42,000 ft.
