THE JOINT NOL/RAE/WRE RESEARCH PROGRAM ON BOMB DYNAMICS. PART II. A LOW-DRAG BOMB WITH SPLIT-SKIRT STABILIZERS,

摘要

Research on the free-fall dynamics of bombs has been conducted as a cooperative program supported by organizations in the United States,United Kingdom and Australia. In addition to full-scale flight trials of instrumented research stores carried out by the Australian Weapons Research Establishment (WRE),wind-tunnel tests have been made on mutually agreed models at the Aircraft Research Association and Royal Aircraft Establishment (RAE) in England;the Naval Ordnance Laboratory (NOL) in the United States;and at the Aeronautical Research Laboratory in Australia. RAE,WRE and NOL have separately prepared digital-computer programs to simulate test vehicle trajectories using wind-tunnel measurements as inputs. Correlation between the predicted and observed flight results have provided considerable insight into problems associated with dynamic behavior during the critical release phase and stability criteria needed for good ballistics consistency. This is the second report on the research program and it presents results relating to the study of split-skirt stabilizers. (Author)
