Embodiment 1

[0035] see Figure 1-4 . Such as Figure 1-4 As shown, the embodiment of the present invention provides a compartment separation device for a space vehicle, including a base 1, a sleeve 2, a push rod assembly 3, a push spring 4 and an adjusting gasket 5, and the separation device passes through the sleeve 2 External mounting lugs 23 can be mounted on one of the two compartments to be separated,

[0036] The base 1 is a cover-shaped structure with an internal thread, which is combined with the sleeve 2 to form a relatively closed cylindrical cavity; the bottom end of the sleeve 2 is fixedly connected to the base 1, and the sleeve 2 It not only provides the circumferential constraint of the push spring 4, but also acts as a guide for the push rod 31, and also serves as a component of the installation interface.

[0037] The push rod assembly 3 is a metal element, including a push rod 31 and a piston 32. The top of the push rod 31 is in the shape of a truncated cone. Compared ...

Embodiment 2

[0057] On the basis of Embodiment 1, an embodiment of the present invention further provides a space vehicle, the space vehicle includes the compartment separation device described in the above-mentioned Embodiment 1.

[0058] To sum up, the cabin separation device of the space vehicle of the present invention is applied to the on-orbit separation between the two cabins of the on-orbit vehicle, and the spring force of the push rod spring is adjusted by using the adjusting gasket, which can ensure that multiple separation devices The consistency of the thrust when working together, the separation device combined with the point connection method between the cabins can effectively improve the smoothness of the aircraft cabin separation process and reduce the attitude disturbance caused by the separation of the cabins; the sleeve, The ejector rod and the base have been optimized for weight reduction. While ensuring their functional performance, the product quality has been reduced....

Abstract

The invention provides a compartment separation device for a space vehicle, comprising a base, a sleeve, a push rod assembly, a push spring and an adjusting gasket, the bottom of the push spring is in conflict with the base, and the top of the push spring is in contact with the push rod In contrast, there is a groove on the base, and the adjusting gasket is located in the groove to adjust the push force of the push rod by adjusting the push spring. The sleeve is installed on the docking ring of the first cabin of the space vehicle, and the push rod is arranged on The end face of the docking ring of the second cabin of the space vehicle, when there is no external force constraint, the piston is placed on the top of the sleeve; when the space vehicle is launched, the ejector rod is pressed into the sleeve; Promote the reverse movement of the first compartment and the second compartment to complete the separation. The invention can ensure the consistency of the thrust when a plurality of separation devices work together, can effectively improve the smoothness of the cabin section separation process of the aircraft, and reduce the attitude disturbance caused by the cabin section separation.

Description

technical field [0001] The invention relates to the technical field of space vehicles, in particular to a space vehicle and a compartment separation device thereof. Background technique [0002] With the development of aerospace technology, the application of point connections has gradually increased, and higher requirements have been put forward for the design of the separation device used for the separation of the two compartments of the spacecraft, including higher product reliability, lower product quality, The stricter consistency of the thrust of multiple products makes the design more and more refined, concise and intensive. These requirements are crucial to ensure the smooth separation of the two cabins in orbit and the realization of relevant technical indicators. [0003] The Chinese utility model patent with the publication number CN202670104U provides an aircraft cabin interstage separation device, which includes a connecting and separating device body, and one ...
