Description

Flight tests of fifteen T-231 70-mm HEAA rocket projectiles (flight components of the T-263 HEAA rounds) were made at the Langley Pilotless AIrcraft Research Station at Wallops Island, VA., to obtain flight trajectories at high quadrant elevation launchings and to obtain drag data. Although all rounds were of the same general type, there were differences in nozzle cant angles, number of nozzles per round, shape of head and fuse, motor case length, and type of propellant. All projectiles were launched at an elevation angle of 60 deg. Two of the projectiles tumbled; the remaining thirteen flew successfully. Maximum velocities varied ... continued below

Description

Flight tests of fifteen T-231 70-mm HEAA rocket projectiles (flight components of the T-263 HEAA rounds) were made at the Langley Pilotless AIrcraft Research Station at Wallops Island, VA., to obtain flight trajectories at high quadrant elevation launchings and to obtain drag data. Although all rounds were of the same general type, there were differences in nozzle cant angles, number of nozzles per round, shape of head and fuse, motor case length, and type of propellant. All projectiles were launched at an elevation angle of 60 deg. Two of the projectiles tumbled; the remaining thirteen flew successfully. Maximum velocities varied between 2,775 and 3,185 feet per second. The time to reach maximum velocity varied between 1.3 and 1.95 seconds. Altitude measured 10 seconds after launching varied between 13,950 and 14,915 feet, ad maximum altitude varied between 19,500 and 21,000 feet. Drag coefficients were obtained over a range of Mach number from 0.7 to 2.6. Maximum drag coefficients varied between 0.45 and 0.50. Results obtained from the last five rounds hwich were identical within manufacturing tolerances were in close agreement.

National Advisory Committee for Aeronautics Collection

The National Advisory Committee for Aeronautics (NACA) was a U.S. federal agency founded on March 3, 1915 to undertake, promote, and institutionalize aeronautical research. On October 1, 1958 the agency was dissolved, and its assets and personnel transferred to the newly created National Aeronautics and Space Administration (NASA).
