CU SRL was the first thing I sought out when I came to CU as a freshman. Since joining over two and a half years ago, projects I’ve done with this team have taught me an immense amount about rocket propulsion engineering, manufacturing, composites, CAD, simulation, and more. For a little over two years, I was the team lead responsible for developing a composite rocket motor capable of launching our Spaceshot vehicle past the 100km barrier known as the Kármán line for about two years, and have made a lot of flames happen in the process. Now, I’m in charge of pushing our incredible team to implement better engineering practices to make good products on extremely tight timelines. I have done a lot of work for almost every team we have over the past two and a half years, and in doing this have developed a solid understanding of everything we do. I am also in charge of turbopump development for our liquid engine team!

owen kaufmann- liquid engine development

Liquid engines are a technology that very few student organizations have ever attempted. They are where the rubber meets the road in terms of when rocket science becomes “rocket science”. By developing our first two liquid engines, SRL is furthering the tradition of setting the next bar high. As team lead, I am working to get a liquid bipropellant rocket engine tested Spring 2021, and to give Spaceshot a run for its money (or an alternative propulsion option) before Spring 2022. It is a uniquely opportune time for SRL to pursue liquid engine development, as we now have the capability to merge the composites technologies we have perfected with additive manufacturing of exotic materials.
My particular investment in this project stems from my passion for inspiring people. I want to work with my peers to build something that inspires the next generation of innovators, the same way that aircraft like the SR-71 and XB-70 inspired me to pursue my dream job as a vehicle engineer in Northrop Grumman Special Programs.

Chris lolkema- obsidian lead

Hey! I’m Chris and I’m a Sophomore, and more importantly an aspiring Aerospace Engineer, out of Washington State. For as long as I can remember I have always had a passion for engineering and aerospace, some of my earliest memories include building elaborate Lego spaceships and space ports. It was only natural that I would end up half a country away at the University of Colorado. I have been involved with SRL since my first semester at CU and was immediately drawn to the community and support this club offers. The main projects that I have helped with have been Diamondback, Space Shot and the Obsidian Launch Vehicle where I eventually became the project lead for. SRL has and will continue to be an amazing club to be a part of and I am excited to see what the future holds for us.

ian faber- Ground control systems lead

Hey there! My name is Ian Faber, and I’m the Ground Control team lead here at SRL! I’m currently a freshman pursuing a degree in aerospace engineering sciences as well as a double minor in applied mathematics and electrical engineering (or signals and systems, I can’t choose…). I’ve always had a sweet spot for electronics, and I’ve dabbled in everything from Arduino to Raspberry Pi, creating projects ranging from RC holonomic robots to camera vision navigating pirate ships! I love all things space and science, and I’m incredibly excited to have the opportunity to lead this integral part of SRL. On a personal level, I’m a pretty chill guy. I love playing video games, reading, and messing around with whatever “higher-level” concepts I can get my hands on. I also dabble in making synthwave music from time to time, and I’m always down for a card game.

sam ciesielski- fiberwinder lead

Greetings! I am a sophomore studying Engineering Physics interested in materials science. At SRL I’ve worked on vehicle design, composites manufacturing, and liquid propulsion development. I lead a team dedicated to finding elegant means of going from fibre and epoxy to space-quality parts through process engineering of our filament winder. In short, we make the machine that makes the machine. The winder allows us to manufacture custom composite airframes, nosecones, solid rocket motors, liquid rocket engines, and propellant tanks. Our current focus is the construction of a new 4-axis fiber winder which we’ve designed in house. Soon to be operational, this machine will allow us to wind larger parts faster with more complex contours while maintaining complete control over the process. This is essential to our goal of implementing a spaceshot vehicle production system and the development of COPVs for our liquid propulsion endeavors.
