Abstract: |
Introduced a kind of the multi-functional structure and manufacturing process in the spacecraft. This multi-functional structure was mostly applied in the honeycomb sandwich panel. The devices with the functions of mechanical connection, telemetry, tracking and command, power supply, communications and temperature control were simultaneously embedded in the panel. These devices were assembled bonded in the honeycomb sandwich panel after the effective protection and position by the vacuum-autoclave molding method. This integrated structure possessed the functions of different sub-systems such as structure, telemetry and command, power supply, antenna and thermal control. The advantages of the multi-functional structure and its manufacturing process were lightening the structure weigh, increasing the effective space and improving the quickly responding ability. |
