核動力衛星 的英文怎麼說
中文拼音 [hédònglìwèixīng]
核動力衛星
英文
nuclear-powered satellite-
In 1978, a nuclear - powered soviet satellite plunged through earth ' s atmosphere and disintegrated, scattering radioactive debris over parts of northern canada
1978年的今天，一顆蘇聯造的以核能為動力的衛星在穿過大氣層時候發生砸裂，其具有發射性的部分殘劾散落在加拿大北部The air bearing is the most important part of an attitude control system simulator for simulating a satellite moving in the weightless circumstance. performance of a satellite attitude simulation system based on air bearing is decided by the inertia matrix and gravity disturbance torque arising from a difference between mass center and rotation center, and air bearing can be used to simulate the algorithm of on - line mass - property parameters identification on the ground. so the problem of mass - property and gravity disturbance torque identification for satellite and air bearing is studied in this thesis
氣浮臺能夠模擬衛星在軌失重條件下的姿態運動，是衛星姿態控制系統物理模擬的核心部件，其轉動慣量和質心偏移引起的重力干擾力矩等決定了基於氣浮臺的衛星姿態物理模擬系統的性能，並且利用氣浮臺可以實現衛星質量特性在線辨識演算法的地面物理模擬驗證，因此本文對衛星和氣浮臺的質量特性及干擾力矩在線辨識問題進行深入研究。
