碩士 / 國立中央大學 / 機械工程研究所 / 95 / The purpose of this paper is to demonstrate the design approach for the mechanical structurre of reentry capsule for Sounding Rocket VI Mission in Taiwan. The design of the reentry capsule must ensure the re-use of the carried precise instruments and the retrieve-back of valuable data. The reentry capsule must also resist high reentry heat and suffer the impact forces when separating from the rocket and falling into the water. Meanwhile, during reentrying into the erath, the reentry capsule must keep a steady fly and a stable posture to let the parachute open smoothly. The other requirement for the design task is that the control system and the instruments must be operated steadily in Sounding Rocket VI Mission.
During the design process, from defining the structural requirements to the final ground tests, a comparative method was used to realize the difference between the various existing designs and their mechanical structures. The outline of the mechanical structure was made based on the comparison. Finally, the strength of the structure and the optimal dimensions were also analyzed by using COSMOSWorks software.
The reentry capsule’s structure, developed in the study, includes the heatproof-shield with the requirements of counterweight and strength, the main part of the capsule, the top cover with sealing and the parachute-protected shell structure for protecting and opening the parachute, and the othe accessories for fixing the electronic components.
A serie of ground tests for the body of the reentry capsule were conducted by Chung-Shan Institute of Science and Technology to verify whether the structure design fulfills the requirements of the reentry mission. After design changes and the corresponding validation, the reentry capsule has been verified from the necessary ground tests and is available for the launch of the sounding rocket mission.
