Abstract

The invention provides an outboard on-orbit operated ground test method of spacecrafts. The ground test method comprises the following steps of installing a test article to a servo mechanism, installing gloves of an outboard space suit, and closing the door of a vacuum tank; adjusting the test article to fit the operating position of the gloves of the outboard space suit, regulating the air pressure in the vacuum tank to a preset pressure value, and completing an outboard test operation by a user wearing the gloves of the outboard space suit; returning to the original state after the test operation. The ground test method achieves verification of the outboard on-orbit operated ground test of spacecrafts, and solves the problem that outboard on-orbit operated tests need verifying during long-term on-orbit flights of the spacecrafts.

Description

technical field [0001] The invention relates to a ground test method for on-orbit operation outside the cabin of a spacecraft. Background technique [0002] Spacecraft operating in orbit for a long time has high reliability requirements, and its development is unprecedentedly difficult. [0003] The "Mir" space station has extended its lifespan to 15 years through maintenance, and 75% of the time during the life extension period astronauts are performing maintenance work. The life of the International Space Station will be extended to 2024 through maintenance. Astronauts spend 40% of their daily maintenance work. As of September 2016, a total of 384 out-of-cabin maintenance have been carried out. In its more than 20 years of in-orbit operation, the Hubble Telescope has received multiple maintenance services such as the replacement of gyroscopes, batteries, and precision guidance sensors. On-orbit maintenance is an indispensable key measure to ensure the normal on-orbit ope...
