Overview

The goal of the Liquid Propulsion subteam is to continually learn more about bi-propellant liquid rocket engines, by designing, manufacturing, and testing

our own engine. While the other subteams on Rocket Team support a central rocketry project, Liquid Propulsion instead focuses on design of

an

independent

engine. Currently, the team is getting ready to hot fire their Helios engine

,

and is

finishing the design of their Romulus engine.

Helios

Image Added

In the Fall of 2018, the team began the Helios engine project. Helios is a pressure-fed bi-propellant liquid engine designed to produce 350lbf, and is fed with diluted Ethanol & LOX by an accompanying test stand. Helios's main goals are to understand basic engine design principles and learn how to efficiently and safely test high-pressure engines. As of now, Helios has been successfully assembled, and was successfully hot fired on May 16th, 2024.

Romulus

Image Added

Romulus, a Kerosene-LOX regeneratively cooled engine designed to produce 450lbf, expands on lessons learned from the design of Helios. Romulus uses a pintle injector to balance thrust and temperature requirements. This project was discontinued because there was not enough time and members to finish it.

Learning Curriculum

The liquid prop team has developed an on-boarding curriculum to provide new and existing members with an introduction into various important concepts that are necessary to know on the team. These topics include basic engine design, incompressible flow fundamentals, combustion fundamentals, feed system design, as well as more advanced topics. Click the header above to explore the different learning resources.

Research

Through the design of engines, and recent research endeavors, the team has compiled various write-ups and findings relevant to our work. Past findings from previous projects can be found here, along with findings from the research initiative that the sub-team began in October 2020 (which then became Project Romulus!).

Project Helios

In the Fall of 2018, the team began the Helios engine project. Helios is a pressure-fed bi-propellant liquid engine designed to produce ~350lbf, and is fed with diluted Ethanol & LOX by an accompanying test stand. Helios's two main goals are to:

Understand basic engine design principles by building a simple engine.
Learn how to efficiently and safely test high-pressure engines by building a pressurized feed stand.

As of now, Helios has been successfully assembled, and is nearly ready for its hot fire test. To read more about Project Helios, click the link above.

Project Romulus

Having been forced off-campus for some time, the team began their Romulus engine project in the Summer of 2020, springing off the research initiative started the Fall prior. Romulus expands on lessons learned from the design of Helios, being a Kerosene-LOX regeneratively cooled engine designed to produce ~450lbf. Romulus' main goals are to:

Incorporate active and passive cooling methods, including regenerative cooling.
Design a pintle injector to balance thrust and temperature requirements.
Continue to expand the team's experience in system design and safe testing.

As of now, the Romulus engine is being manufactured, and other aspects of the feed system are being worked on. To learn more about Project Romulus, click the link above
