Use of Precision Trajectories to Determine Missile Flight Behaviour.
Abstract
The trajectories of five S-curve bomblets have been determined very accurately, on a small gas gun range. The coning behaviour and the trimmed incidence and normal force have been derived from the trajectory data. The general aerodynamic scattering performance is compared with the performance predicted using wind tunnel measurements, and the results are found to be quite consistent with wind tunnel data apart from one rather interesting discrepancy. The bomblets did not trim at the incidence value expected. This has eventually been attributed to small differences in the tail assembly between the models used in flight tests and those used in wind tunnel tests. The results have been verified by additional wind tunnel tests. The information derived from the trials demonstrates the value of simple instrumentation in assessing flight performance of missiles. A great deal of information on S-curve bomblet behaviour has been obtained with relatively little effort, mainly because of the accuracy of the data. (Author)
