卫星轨道辐射热流的计算对于卫星的热控设计和卫星红外特征研究等都具有重要意义。论文根据描述卫星运动模型参数的卫星轨道六要素,利用坐标变换方法确立了卫星任一表面与太阳、地球的位置角度关系,建立了卫星的表面辐射热流计算模型,可用以计算任意轨道参数的卫星在任意时刻太阳辐射、地球反照和地球辐射等主要轨道辐射热流,并以某轨道上六面体卫星为例给出了其不同表面在整个轨道运行期间的接收到的辐射热流计算结果。结果表明:卫星不同表面接收到的辐射热流密度随时间的变化是不一样的,主要取决于各表面与太阳和地球的角度关系。
衛星軌道輻射熱流的計算對于衛星的熱控設計和衛星紅外特徵研究等都具有重要意義。論文根據描述衛星運動模型參數的衛星軌道六要素,利用坐標變換方法確立瞭衛星任一錶麵與太暘、地毬的位置角度關繫,建立瞭衛星的錶麵輻射熱流計算模型,可用以計算任意軌道參數的衛星在任意時刻太暘輻射、地毬反照和地毬輻射等主要軌道輻射熱流,併以某軌道上六麵體衛星為例給齣瞭其不同錶麵在整箇軌道運行期間的接收到的輻射熱流計算結果。結果錶明:衛星不同錶麵接收到的輻射熱流密度隨時間的變化是不一樣的,主要取決于各錶麵與太暘和地毬的角度關繫。

The calculation of radiant heat flux on satellite orbit is of great significant for satellite in both the thermal design and control and research of its infrared features. In this paper, firstly combined with the six elements of satellite orbit parameters which describing satellite motion model, and with the use of the coordinate transformation method, the position relationship and angle relationship of the satellite′s each surface and the sun. The earth were established. Secondly, the satellite surface radiation heat flux calculation model was established. And the major orbit radiation heat flux such as solar radiation, earth-reflection and the earth radiation of satellite with any orbit parameters and at any time can be calculate with the model. Thirdly, taking a hexahedron satellite in an orbit for instance, the radiant heat flux on its different surfaces during the period on the orbit was calculated. Results show that different surface received radiant heat flux are not the same, which mainly depend on the angle relationship of the surface and the sun and the earth.
