Exciting advancements in space technology are on the horizon, as Champaign-Urbana Aerospace (CUA) prepares to demonstrate a series of cutting-edge micropropulsion systems designed for small satellites. These innovative technologies aim to provide a responsible solution for satellite manufacturers grappling with the increasing challenge of orbital debris.

CUA's suite of micropropulsion systems encompasses a diverse range of capabilities tailored to meet specific mission requirements, from high thrust to exceptional specific impulse. Here are some key benefits of these life-cycle propulsion solutions:

Collision avoidance

Orbit raising and lowering

Inclination adjustment

Rendezvous capabilities

Orbit maintenance and drag compensation

Safe deorbiting at the end of a satellite's operational life

As concerns over orbital debris escalate, CUA’s propulsion technologies will play a crucial role in addressing these issues, particularly by adhering to newly established regulations by the U.S. Federal Communications Commission (FCC) that mandate deorbiting satellites within five years of mission completion.

The Game-Changing Technologies

Fibre-fed Pulsed Plasma Thruster (FPPT) The FPPT is a remarkable innovation that vaporizes Teflon and accelerates ions using a high-energy short pulse, achieving a specific impulse greater than 3500 s. Remarkably compact, with sizes ranging from under a liter to over 50 liters, the FPPT can deliver total impulses between 1,000 and 600,000 N-s. This technology is not just efficient but also offers unique capabilities, including electromagnetic thrust vectoring, making it suitable for a variety of maneuvers in space.

Monofilament Vaporization Propulsion (MVP) Utilizing a novel approach akin to 3D printer technology, the MVP system employs a low-power resistojet to provide continuous electrothermal thrust. Generating a specific impulse of 66 s, this system remains cost-effective while ensuring safety, making it ideal for various micropropulsion needs such as drag compensation and collision avoidance.

Cubesat High Impulse Propulsion System (CHIPS) This versatile propulsion option integrates a main thruster with a highly efficient attitude control system in a compact package. CHIPS features proven technology capable of extensive operation cycles and employs non-toxic propellants, thus ensuring high performance while minimizing risk. With customization options for specific missions, CHIPS represents a state-of-the-art solution in satellite propulsion technology.

Monopropellant Propulsion Unit for Cubesats (MPUC) Introducing a groundbreaking non-detonable monopropellant, CMP-X combines ethanol and hydrogen peroxide to create a powerful yet safe propulsion system. With the ability to maintain thrust levels and operational convenience, the MPUC is an excellent choice for larger CubeSats and small satellites that demand high performance without the risks associated with traditional propellants.

Cycle Automated Mass Flow (CAMFlow) Technology This innovative system ensures precise flow control in electric propulsion systems, enhancing reliability through a simplified control scheme. CAMFlow has been successfully tested in Hall thrusters and is set to revolutionize flow control technology in the industry.

A Dual Propulsion Experiment to Watch

CUA is also set to launch the Dual Propulsion Experiment (DUPLEX) CubeSat, which will serve as a flight demonstrator for both FPPT and MVP technologies. Funded by NASA's Space Technology Mission Directorate, DUPLEX will embark on its mission in early 2025, paving the way for the broader adoption of these groundbreaking propulsion techniques.

A Vision for Responsible Space Operations

With an eye on sustainability, CUA’s advancements not only promise enhanced performance but also focus on ensuring a clutter-free space environment. By facilitating collision avoidance, orbital adjustments, and timely deorbiting operations, these new propulsion systems are poised to redefine how satellites operate and coexist in increasingly crowded orbits.

In a world where space is becoming ever more vital, CUA’s innovative propulsion technologies stand to significantly alter the aerospace landscape, making the cosmos safer for future generations. Keep an eye out as these developments unfold and prepare for a new era of responsible space exploration!
