ABSTRACT |
If a winged reentry space vehicle with non-planar wings such as a tip-fin is attached atop a launch rocket, lateral mode oscillation due to an attachment between the vehicle and the rocket and/or the rocket itself may have an effect on the flutter characteristics of the wings. A particular supporting system was developed for wind tunnel tests, which had a yawing elasticity as a lateral mode. Flutter experiments were conducted in NAL-TWT. Flutter characteristics were also computed by with the doublet-point method (DPM). Numerical results are consistent with experimental results. |
