Abstract:

The large extensible door is an indispensable part of the re-entry space vehicle, such as space shuttle and X-37B transportation vehicle. The length of the door can reach 1/3 to 1/2 that of the airframe. The development process of the door is very difficult due to the complex environment condition and multiplicity function requirements in the full duty cycle. The state of the art of the development of large extensible door is introduced. The common characteristics of the door are given through the analysis of the space vehicle. It is summarized that the key technologies included in the overall design, the thermal protection and heat sealing technology, the repeated deploy and close technology, the repeated lock and unlock technology, etc. The related technical solutions are also given.

Key words: re-entry space vehicle, space shuttle, spacecraft, door, overall design
