“…For these reasons, we have decided to develop a new tool, called Liquid-Propellant Rocket Engine Simulation (LPRES), a simplified library for EcosimPro ® presented in [18]. The tool is, therefore, a simplified version of the ESPSS professional libraries, developed mainly for educational purposes.…”

“…The design step serves both to determine the efficiencies that would make a particular model with the simplified formulation perform closely enough to the available real data, and to perform the basic sizing of the geometry (this is, to calculate the characteristic lengths, radii and free-flow cross-sectional areas of the different components) so that off-design calculations (for which both the efficiencies and the geometry are kept constant) can be tackled subsequently. More details about the formulation used within each component can be found in Sierra et al [18].…”

Successful implementation of active learning strategies in the engineering classroomand in particular in certain subjects which are highly technological in nature such as, for instance, rocket engines and space propulsion-means overcoming certain challenges that arise from the fact that these are extremely complex systems to analyze. In this paper, we address the specific means to overcome one of such challenges: the lack of readily available software tools that are suitable for implementing this sort of teaching strategies within the engineering training. In particular, we develop a new tool for the modeling and simulation of liquid-propellant rocket engines specially tailored for the classroom, taking a systematic approach to the development of such tool based on the needs of modern teaching practices. After a thorough review of the available literature on the topic, the few most critical features that our tool should have in order to serve its purported goal are identified. Subsequently, a pilot experience to assess the impact of the usage of said tool on the learners' performance was carried out, showcasing excellent results, both in terms of the students' perceived quality of their training as well as in terms of their grade of retention and understanding of the matter. The conclusions of this study, especially the guidelines for the development of software tools aimed at the classroom, nevertheless, should be applicable to any other highly technological discipline, extending the scope of this paper beyond merely the subject of rocket science in engineering.
