Force Tests of the 4.5" Rocket, T38E3

This report covers the tests of a 2" diameter model of the 4. 5" H. E. Rocket, T38E3, to determine the force and moment coefficients and the location of the center of pressure. The tests were made in the 14" diameter working section of the High Speed Water Tunnel at the California Institute of Technology. The work was authorized by a letter of January 31, 1944, from Dr. E. H. Colpitts, Chief of Section 6.1, National Defense Research Committee, New York City.
