The Static and Magnus Aerodynamic Characteristics of the M823 Research Store Equipped with Fixed and Freely Spinning Stabilizers

Pagination or Media Count:
The report is the first in a two-part series of technical reports on the dynamics and aerodynamics of free-fall stores using freely spinning stabilizers. Presented are the results of recent wind-tunnel measurements of the normal force, pitching moment and Magnus force and moment on the M823 Research Store in transonic flow. Comparisons are made between configurations equipped with fixed and freely spinning stabilizers, with regard to sign and relative magnitude of the Magnus force and moment. A method is presented and applied whereby the Magnus force and moment are corrected for flow angularity.
