Embodiment Construction

[0055] Such as figure 1 As shown, the steps of the method for designing a space station safe area that meets passive safety requirements in this embodiment include:

[0056] 1) No fly ball design;

[0057] 2) The radial pulse transfer is close to the ellipsoidal design;

[0058] 3) The tangential pulse transfer is close to the ellipsoidal design.

[0059] With reference to the experience of the International Space Station, the setting of the safety area of ​​the space station in this embodiment mainly includes two parts: a no-fly sphere and an approaching ellipsoid, such as figure 2 shown. The outer control area is called the ApproachEllipsoid (AE), which is an ellipsoid centered at the center of mass of the space station, and the minor axes of the R-bar and H-bar are equal to half of the major axis of the V-bar. In the process of guiding to the point S2 outside the approaching ellipsoid, it must be guaranteed not to collide with the approaching ellipsoid under any error ...

Abstract

The invention discloses a space station safe region design method capable of satisfying the passive safety requirement. The space station safe region design method comprises steps of the design of a keep out sphere, the design of a radial pulse transfer approach ellipsoid and the design of tangential pulse transfer approach ellipsoid. The design of the keep out sphere comprises steps of determining the design principle that the keep out sphere satisfies the passive safety requirement, establishing a relative dynamics and deviation forecast model of a visiting spacecraft and a space station, calculating the shortest ellipsoid distance between a spacecraft united enveloping sphere and a relative track error ellipsoid, assuming that the visiting spacecraft begins to fly around the V-bar boundary of the keep out sphere in dependence on the design principle that the keep out sphere satisfies the passive safety requirement, changing the radius of the keep out sphere, analyzing the relationship between the shortest ellipsoid distance when the visiting spacecraft flies around the keep out sphere and the change of the radius of the keep out sphere, and completing the design of the keep out sphere. The pace station safe region design method is advantaged in that the design method is correct and reasonable, safety of the space station is guaranteed, sufficient time is provided for the visiting spacecraft to remove the fault, and the design result is suitable for practical engineering tasks.

Description

technical field [0001] The invention relates to a space station safety area design technology, in particular to a space station safety area design method meeting passive safety requirements. Background technique [0002] As a long-term on-orbit scientific research platform, the space station can make full use of a variety of special space resources to carry out basic research in medicine, astrophysical sciences, biological sciences, and new materials science, which has important application value. During the construction and operation of the space station, it is necessary to frequently rendezvous with visiting aircraft to complete tasks such as load transportation, crew rotation, and material replenishment. The space station is expensive, bulky, and the rendezvous tasks are complicated and diverse, so it is necessary to pay enough attention to the safe rendezvous and docking of visiting spacecraft. At the beginning of the design of the International Space Station, correspon...
