Comparison of flight test results and 6-DOF calculations using the incremental coefficient method for store releases from the F-111 weapons bay

OSTI ID:7212074
Wind tunnel incremental coefficient data were used to calculate the six degree of freedom motion of a 2400 pound store being released from the weapons bay of the F-111 aircraft. Subsequent flight test results have been compared with these calculations to show an excellent agreement over an airspeed range of 300 to 500 KCAS. Additional flights will provide comparisons up to approximately 650 KCAS. The comparisons to date indicate that the simplified grid simulation method gives a very reasonable prediction of the motion for weapon bay releases of low static margin stores. Of special interest is the method for obtaining the incremental aerodynamic coefficients inside the weapons bay which is detailed.
