A large body of wind tunnel data was generated by tests | |
of a smooth missile model with several interchangeable | |
nose parts. The tests were conducted at subsonic through | |
supersonic speeds at angles of attack from 0 to 180 | |
degrees. They were part of the FDL and SAMSO technology | |
studies which preceded design of the MX missile. | |
Measurements of both surface pressures and total forces | |
and moments were made at a variety of Mach numbers and | |
Reynolds number combinations. This data was supplemented | |
with wake flow-field measurements of the impact pressure | |
and flow direction at angles of attack where maximum | |
induced side force was expected to occur. A review of the | |
literature for subsonic and transonic aerodynamic | |
characteristics of bodies of revolution was conducted. A | |
comprehensive discussion is provided of the important | |
variables of the high angle of attack flow phenomena. The | |
test data provided insight into the effect of several | |
variables that had not been adequately treated in the | |
past. The high angle of attack data was analyzed to | |
deduce the vortex shedding location, the vortex strength, | |
and the vortex paths in the wake. Discrete vortex theory | |
was examined as a method which could be modified, based | |
on experimental data, and used to predict the aerodynamic | |
characteristics of missiles to greater accuracy. An | |
alternate approach to developing a prediction method was | |
explored by means of a correlation of the surface | |
pressure data. | |
