Abstract

A literature survey was conducted to determine the factors which affect aerodynamic drag of spheres. Graphs are presented which show the effect of each variable where such information was available. Equipment was designed and built for the purpose of studying the effects of acceleration on the aerodynamic drag of spheres. Special emphasis was placed on the measurement and control of each of the other variables which can affect the drag. Tests were conducted using large spheres in air and water to show that the method presented can produce a valid determination of the drag coefficients. The numerical values of the measured data cannot be considered accurate because of known discrepancies in the test equipment. Information is also presented on the use of this equipment for tests with small diameter spheres. Recommendations are made for further testing on the aerodynamic drag of spheres and for needed changes and additions to the test equipment.
