Abstract:

An analysis is presented of the full scale, free flight dynamic behavior of a tri-partite bomb of split-skirt and variable drag configuration. The angular data was obtained from internal instrumentation from the drop at the Woomera Test Range in Salisbury, Australia by the Australian Weapons Research Establishment. This test was part of a joint research program on instrumented bombs undertaken by the United Kingdom, Australia, Canada, and the United States. The analysis was carried out by the Department of Aero-Space Engineering, University of Notre Dame. The bomb was observed to experience Catastrophic Yaw in the early phase of the flight, while a Magnus instability was evident in the latter phase. An analysis of the last half of the flight data yielded an excellent determination of the aerodynamic stability coefficients.
