Description

The X-1 was a rocket engine-powered aircraft. It was a joint National Advisory Committee for Aeronautics, U.S. Army Air Forces and U.S. Air Force supersonic research project built by Bell Aircraft. Conceived during 1944 and designed and built in 1945, it achieved a speed of nearly 1,000 miles per hour (1,600 km/h) in 1948.

Historical Background

The X-1 (originally designated XS-1) is the legendary rocket engine-powered research aircraft that became the first airplane to break the sound barrier in controlled, level flight.

Key Milestones & History
• The Historic Flight: On October 14, 1947, Captain Charles "Chuck" Yeager piloted the X-1 #46-062—which he famously nicknamed "Glamorous Glennis" after his wife—to a speed of Mach 1.06 (approx. 700 mph / 1,127 km/h) at an altitude of 43,000 feet over the Mojave Desert.
• The Rib Injury: Famously, Yeager broke two ribs in a horse-riding accident the night before the historic flight but concealed the injury, using a broom handle to help latch the cockpit door shut.
• Peak Performance: The original aircraft eventually reached a maximum speed of Mach 1.45 (957 mph) in March 1948 and a peak altitude of 71,902 feet in 1949.
• Current Status: Following its retirement in 1950 after 78 flights, the historic Glamorous Glennis was transferred to the permanent collection of the Smithsonian National Air and Space Museum in Washington, D.C.

Design & Technical Specifications
Developed as a joint project between the NACA (the predecessor to NASA), the U.S. Army Air Forces, and Bell Aircraft, the X-1 was built entirely to gather aerodynamic data in the transonic and supersonic speed regimes.

Fuselage Shape: Modeled after a .50-caliber machine gun bullet, an object known to be inherently stable at supersonic speeds.
Engine Type: Powered by a four-chamber Reaction Motors XLR11 liquid-propellant rocket motor generating 6,000 lbs of thrust.
Fuel System: Burned a volatile mixture of liquid oxygen and diluted ethyl alcohol. The engine was unthrottleable; the pilot adjusted speed by physically toggling the 4 individual combustion chambers on or off.
Launch Method: The aircraft could not take off autonomously due to fuel capacity limits. It was carried to an altitude of ~25,000 feet inside the bomb bay of a modified Boeing B-29 Superfortress mothership and air-launched.
Structural Load: Engineered to an extraordinary ultimate load factor of 18g to protect the pilot against intense high-speed buffeting.
Dimensions: Length: 31 ft (9.42 m) | Wingspan: 28 ft (8.53 m).

Additional Information

The model was created based on blueprints, photos and historical documentation. It was created with precision in detail and in real units of measurement to be a faithful digital reproduction of the original.
Cockpit NOT INCLUDED.
LIGHTWAVE and BLENDER - The scene contains the model with uv materials assigned and in the rigged version a basic setup to control each movable part, such as ailerons, rudder, elevators, propeller and wheels.
If you need to animate the airplane you have to make your own setup according to the 3d software you are using. You may need to reassign uv textures when open the files with different software. The aircraft is subdivided into parts each one with its uv map. To reassign textures you only have to load texture maps and assign each of them to the respective channel.
