Embodiment Construction

[0048] The present invention will be further described below in conjunction with accompanying drawing and example, but present embodiment is not intended to limit the present invention, and every similar method of the present invention and similar changes thereof should be included in the protection category of the present invention.

[0049] Depend on figure 1 It can be seen that the present invention provides a method for designing an energy optimal moon-earth transfer orbit based on a lunar ladder, which includes the following four steps:

[0050] Step 1: Design the moon-earth transfer scheme based on the lunar ladder

[0051] Such as figure 2 As shown, the moon-earth transfer scheme based on the lunar ladder is divided into four stages: the climbing section, the moon-centered elliptical orbit section, the moon-centered hyperbolic orbit section and the earth-centered elliptical orbit section. The relationship between these four stages is a sequential relationship in time...

Abstract

The invention provides an energy optimization moon-earth transfer orbit design method based on a moon high ladder. The method comprises the steps that 1, a moon-earth transfer scheme based on the moon high ladder is designed; 2, an energy analysis model of the transfer scheme is built; 3, an energy optimization model of the transfer scheme is built; 4, the transfer scheme is subjected to energy optimization. According to the energy optimization moon-earth transfer orbit design method, the novel moon-earth transfer scheme based on the moon high ladder is built, meanwhile, the energy optimization of a transfer orbit is achieved, the energy consumption in the moon-earth transfer process is lowered, and the problems of large energy consumption and high cost in the traditional transfer scheme are solved.

Description

technical field [0001] The invention relates to an energy-optimized moon-earth transfer track design method based on a lunar ladder, which can solve the problems of large energy consumption and high cost in traditional moon-earth transfer schemes, and belongs to the field of aerospace technology. Background technique [0002] With the continuous deepening of human exploration of space, the existing delivery technology is increasingly unable to meet the requirements. At present, the main vehicle for entering space in the world is the launch vehicle. The scale and level of the launch vehicle support the ability to enter space. However, the efficiency of the launch vehicle is very low. The mass of the payload is less than 10% of the overall mass of the rocket, and the propellant accounts for more than 90% of the mass. The delivery technology based on the ladder technology stands out for its novel concept and powerful advantages. [0003] Sky ladder, also known as space elevat...
