Embodiment Construction
[0019] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0020] The invention provides a method for test spraying of an engine on an earth-moon transfer track, which considers implementing the test spraying of the engine when the earth-moon transfer is corrected midway. The midway correction of the earth-moon transfer is used to correct the orbit deviation caused by errors such as loading into orbit and orbit determination, so as to ensure that the probe can reach the moon in the expected near-moon state. Generally, 3 midway corrections are arranged for the Earth-Moon transfer segment, and 1-2 midway corrections will be canceled in actual flight according to orbital parameters and control implementation. However, the amount of orbit change in the midway correction is usually small, and it is not necessary to use a large-thrust engine to implement it. Especially in the case of launch and orbit determination with...
