The dynamic stability of the reentry capsule configuration was investigated both experimentally and numerically. The dynamically unstable behavior was observed especially at transonic regime while, at subsonic regime, an intermittent unstable behavior was observed even though an oscillation amplitude is small compared with the one at transonic regime. At supersonic regime, the dynamically unstable behavior observed at transonic regime disappears. At transonic regime, the limit cycle oscillation was observed as a result of the dynamic instability. The results of both the experiment and the numerical simulation show a reasonable agreement. The dynamic pitching moment during the oscillation was modeled for the front and rear part, separately. It is shown that the pitching moment during the oscillation can be evaluated by considering the dynamic effect on the static aerodynamic characteristics. Based on the modeled pitching moment, a theory for the dynamical instability is proposed, which gives not only the growth rate of the oscillation but also the limit cycle oscillation amplitude. According to the theory, the primary cause for the dynamic instability is the dynamical part of the pitching moment at the rear part of the capsule, which is generated by the vortical flow behind the capsule. The dynamical part of the pitching moment at the front part of the capsule works as a stabilizer. Both the growth rate and the limit cycle oscillation suggested by the theory shows a reasonable agreement with the experiment and the numerical simulation. |
