[0002] The instrument cabin, the "brain" of the launch vehicle, belongs to the upper stage structure of the launch vehicle. It is equipped with the control system, instruments and equipment of other systems, and the final stage correction system. The instrument cabin of traditional launch vehicles is often arranged at the front end of the rocket body, which is far away from the engine and has less vibration, which is beneficial to the instruments and equipment.

[0003] The traditional instrument cabin is generally connected to the fairing on top, and there is usually a transition frame between the two structures to support the separation of the fairing. Specifically, the top of the instrument cabin is connected to the bottom of the transition frame, and the transition frame has an explosive bolt box inside, which is connected to the fairing with explosive bolts. The outside of the transition frame is equipped with a separation hinge and a spring top seat, which are used to spring open the fairing and separate the half-cover. The advantage of this setting is that the upper and lower stages can be connected and separated in an orderly manner, and the structural reliability is high. However, the transition frame is generally a whole ring. In order to meet the strength requirements, the wall thickness is at least 5mm, which leads to a lot of redundant weight beyond the structural function, which greatly reduces the carrying capacity of the carrier and also increases the launch cost invisibly.
