Design of a typical aerospace interstage structure using orthogrid ...
2023年5月17日 · In this study, an interstage cylindrical shell structure of a Launch Vehicle is designed with isogrid and orthogrid configurations, which are integral-rib-stiffened-skin configurations to have mass-optimised aerospace structures.
Structural Design and Fabrication of a Rocket - CORE
Our senior project will focus specifically on the structure of the rocket. This includes the rocket body, and securing any subsystems. The motor, electronics bay, and recovery system are example of components which will need to be mounted. The project consists of two parts.
This structure performs several functions including primary launch vehicle load carrying, separation of the corresponding interior MPCV and DCSS environments through a spherical cap diaphragm, cable interface panels, access panels, and attachment interfaces for electrical cable wiring harness to span the ...
Study on panel flutter considering unsteady deceleration and …
1 天前 · Thin-walled elastic structures, which are frequently applied on reusable rocket bodies, can experience panel flutter issues easily under unsteady aerodynamic loads. After separation of the ascent stage or during the recovery stage, the first stage of the rocket may undergo a deceleration period in the transonic region.
