Embodiment Construction

[0028] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0029] See attached figure 1 , the embodiment of the present invention provides an analysis and evaluation method for the contribution rate of the liquid launch vehicle system, the analysis and evaluation method is according to figure 2 The structure and levels shown in the evaluation are divided into three levels: target level, criterion level and program level. The first layer is the target layer, which is mainly for the evaluation of meeting the requirements of payload launch, including carrying capacity, target orbit, orbital accuracy, fairing envelope and launch cost, etc. Under the premise of satisfying the capability conditions, the second layer (rule layer) mainly focuses on the combat performance, economy, operation, safety, maintenance and other performance of the rocket. The rule layer mainly reflects the principles of comparison and classific...

Abstract

The invention discloses an analysis and evaluation method for the contribution rate of a liquid carrier rocket system. The analysis and evaluation method comprises the following steps: constructing a carrying capacity target parameter function for representing the capacity of the carrier rocket system; calculating a system capability value of the carrier rocket according to the carrying capability target parameter function; and calculating the system contribution rate of the carrier rocket according to the calculated system capability value. According to the analysis and evaluation method, the system contribution rate of the carrier rocket can be evaluated and quantified, and a quantitative evaluation reference is provided for project approval demonstration, development and construction and the like of the carrier rocket.

Description

technical field [0001] The invention belongs to the technical field of aerospace launch and transportation systems, and in particular relates to an analysis and evaluation method for the contribution rate of a liquid launch vehicle system. Background technique [0002] The launch vehicle is an important part of the space transportation system, and it is also an important guarantee for the construction of the entire space system and the formation of its capabilities. The effectiveness of the launch vehicle system is mainly reflected in the following four aspects: first, from the perspective of launch missions, the launch vehicle provides space entry tools for various satellite launches, manned space missions, and deep space exploration; second, from the perspective of launch orbits, the launch vehicle Rockets provide space entry tools for typical low-earth orbits, sun-synchronous orbits, geosynchronous transfer orbits, large elliptical orbits, and medium-to-high orbits; third...
