摘要

本文概述了L75液体推进剂火箭发动机（LPRE）的设计和开发过程，该发动机将作为卫星运载火箭应用的上层。重点是选择可用的技术、适当的操作周期和最合适的推进剂组合。描述了开发过程中遇到的问题以及由此产生的解决方案。此外，还对上层进行了调查，包括目前全球运行的主要性能数据。由于与以前的开发计划和成本数字相比，经济约束在今天更为重要，因此也对其缺点进行了研究。最后，对巴西L75发动机的发展现状进行了总结。

Upper Stage Liquid Propellant Rocket Engine: A Case Analysis

This paper provides an overview of the design and development process for the L75 liquid propellant rocket engine (LPRE) foreseen as upper stage of a satellite launch vehicle application. Emphasis is put on the choice of available technologies, an adequate operational cycle, and the most suitable propellant combination. Problems encountered during the development and resulting solution approaches are described. Furthermore, a survey of upper stages including their main performance data currently in operation worldwide is presented. Since economical constraints are more important today compared to previous developments schedule and cost figures and their drawbacks are investigated as well. Finally, a summary regarding the development status of the Brazilian L75 engine is reported.
