説明
The deformation of the bow-shock and the pressure fluctuation inside of a simplified model of the supersonic parachute canopy were investigated. As a result, for the time-averaged characteristics in the reconstruction mode, the deformation of the canopy-bow-shock is decreased and the time-averaged pressure inside of the canopy is increased monotonously with the increase in the distance between the capsule and the canopy. These time-averaged characteristics were explained on the basis of simple analytical models. On the other hand, time-varying characteristics are more complicated. In the Separated mode, there was a peak around at the frequency of 2kHz in the spectral of the pressure fluctuation. In the reconstruction mode, the fluctuation of the pressure decreased with the distance between the capsule and the canopy. The distinguishing non-Gaussian probability-distribution-functions were found in the Separated mode and also in the reconstruction mode when the suspension lines were inserted between the capsule and the canopy models. These experimental data of the statistical characteristics in the pressure fluctuation will play an important role to evaluate the numerical methods for the Fluid-Flexible-Structure-Interference (FFSI) phenomena.
