The X-1 program was first envisioned in 1944 when a former NACA engineer working for Bell Aircraft approached the Army for funding of a supersonic test aircraft. Neither the Army nor Bell had any experience in this area, so the majority of research came from the NACA Compressibility Research Division, which had been operating for more than a ...
TT: the maximum thickness in percent of chord, as in a four-digit NACA airfoil code. For example, the NACA 23112 profile describes an airfoil with design lift coefficient of 0.3 (0.15 × 2), the point of maximum camber located at 15% chord (5 × 3), reflex camber (1), and maximum thickness of 12% of chord length (12).
Prior submerged inlet experiments showed poor pressure recovery due to the slow-moving boundary layer entering the inlet. The NACA design is believed to work because the combination of the gentle ramp angle and the curvature profile of the walls creates counter-rotating vortices which deflect the boundary layer away from the inlet and draws in the faster moving air, while avoiding the form ...
USAF, NACA: 1946 High-speed and high-altitude flight First aircraft to break the sound barrier in level flight. Proved aerodynamic viability of thin wing sections. [10] X-1A X-1B X-1C X-1D: Bell USAF, NACA 1951 High-speed and high-altitude flight X-1E: Bell USAF, NACA 1955 High-speed and high-altitude flight X-2: Bell USAF 1952
Aug. 23—LIMA — A life-long dream has come true for Lima resident Karen Anderson. The Neighborhood Assistance Corporation of America aided in the process of Anderson becoming a homeowner.
Clark Y is the name of a particular airfoil profile, widely used in general purpose aircraft designs, and much studied in aerodynamics over the years. The profile was designed in 1922 by Virginius E. Clark using thickness distribution of the German-developed Goettingen 398 airfoil. [1]
A further expansion of the research program permitted Langley Research Center to orbit payloads, starting with NASA's Explorer 9 balloon satellite in mid-February 1961. As rocket research grew, aeronautics research continued to expand and played an important part when subsonic flight was advanced and supersonic and hypersonic flight were ...
Herbert Hoover presents the 1929 Collier Trophy to NACA Chairman Joseph Ames for the NACA cowling. The Robert J. Collier Trophy is awarded annually "for the greatest achievement in aeronautics or astronautics in America, with respect to improving the performance, efficiency, and safety of air or space vehicles, the value of which has been thoroughly demonstrated by actual use during the ...
