Air-inflated floats are used for the recovery of the rocket’s spent stage. The floats enable the spent stage to stay afloat in water which is essential for recovery. The stability of the spent stage in ocean conditions with waves is studied as a multiphase CFD analysis solved with the VOF method with a 6 DOF solver and PISO scheme. The ocean conditions vary from calm sea to raging storms and with this wave parameters (wavelength, amplitude, wave velocity) also increase. The study of rocket spent stage retrieval in stagnant water available in the literature was mimicked. The depth of sinking and stress on the spent stage is focused on by studying the angle of inclination, displacement of the rocket stage and the velocity of impact during impact on the ocean surface. With increasing wave characteristics, the rocket stage becomes more unstable experiences more stress, and topples quickly.

摘要

Air-inflated floats are used for the recovery of the rocket’s spent stage. The floats enable the spent stage to stay afloat in water which is essential for recovery. The stability of the spent stage in ocean conditions with waves is studied as a multiphase CFD analysis solved with the VOF method with a 6 DOF solver and PISO scheme. The ocean conditions vary from calm sea to raging storms and with this wave parameters (wavelength, amplitude, wave velocity) also increase. The study of rocket spent stage retrieval in stagnant water available in the literature was mimicked. The depth of sinking and stress on the spent stage is focused on by studying the angle of inclination, displacement of the rocket stage and the velocity of impact during impact on the ocean surface. With increasing wave characteristics, the rocket stage becomes more unstable experiences more stress, and topples quickly.
