Modeling and Analysis of a LOX/Ethanol Liquid Rocket Engine
Journal of Aerospace Technology and Management, 2018 This work studies the performance and dry mass of the under development LOX/Ethanol L75 liquid rocket engine. To this end, an object-oriented program written in C++ was developed. The program is intended to be versatile and easily extensible in order to analyze different configurations of liquid rocket engines.

A Reinforcement Learning Approach for Transient Control of Liquid Rocket Engines [PDF]
IEEE Transactions on Aerospace and Electronic Systems, 2020 Nowadays, liquid rocket engines use closed-loop control at most near steady operating conditions. The control of the transient phases is traditionally performed in open-loop due to highly nonlinear system dynamics. This situation is unsatisfactory, in particular for reusable engines.
