Fluids and Internal Structures

The Fluids and Internal Structures Team manages propellant storage, delivery systems, and internal structural components that support the rocket's operation. This team ensures proper fluid management throughout the rocket system, from storage to delivery to the engine.

Our work encompasses the design and analysis of propellant tanks, feed lines, valves, and all internal structures that support these critical systems. We work closely with the Engine and Pumps teams to ensure seamless integration and optimal performance.

Projects

IRIS

IRIS is a vertical integrated static fire test stand for LRI’s IPA-LOX ablative engines. IRIS is designed to mimic the structural and fluid line design of LRI’s future liquid flight vehicle, allowing us to get a head start with optimizing the systems we will eventually need on a flying vehicle.

This project brings together plumbing layout, structural design, and systems integration in one hardware platform that can support future engine testing and overall vehicle development.

IRIS Full Stack

Flight Vehicle Preliminary Design

The team is also working on preliminary flight vehicle design, especially the internal structures and mounting strategies needed to support future propulsion and avionics systems.

That includes bracket design, structural analysis, and electronics packaging work that helps turn high-level vehicle concepts into hardware that can actually be built and integrated.

Bracket FEM Analysis

Electronics Box and Plumbing Layout

Alongside structural work, the team is also building out the electronics and plumbing architecture that supports these systems in practice. That includes enclosure layout, routing, and interface planning between the fluid system and the control hardware.

These design studies help make sure future test and flight systems are not only functional on paper, but organized and integration-ready as the hardware matures.
