Test and Evaluation of Magnus Rotors and Other Bodies, Flight Dynamics Data Reduction and Analysis
Abstract
The report documents three separate series of tests conducted for the purpose of determining if small Parafoils (4.5 square foot) can be used successfully for delivering bomblet munitions, the aerodynamic characteristics of BLU-58/B high-density, retarded bombs for supersonic carriage and release as a step toward eliminating serious flight instabilities which induce large wobbling motions, and the feasibility of supersonic dynamic wind tunnel testing to obtain both restoring and damping moment stability coefficients from a single test. After extensive testing of three configurations of small Parafoils (single flare, double flare, and triple flare) with various aspect ratios, conclusion was reached that a 4.5-square-foot Parafoil with an aspect ratio of 2.0 could be used successfully for bomblet munitions delivery. The BLU-58/B tests were not conclusive. Even though the results indicated that the bomb was statically stable in both the retarded and unretarded flight modes, due to the poor quality of the data used in the tests, no precise conclusion could be reached with respect to aerodynamic characteristics. A wrap around fin missile was used in the supersonic wind tunnel testing procedure with good results. The technique furnished both restoring and damping moment stability coefficients from a single test.
