Project LARSS - Low Altitude Rocket Stability System

The objective of Project LARSS is to build a Low Altitude Rocket Stability System and testbed as a proof of concept for future Saint Louis University Rocket Propulsion Laboratory (SLURPL) rocket projects. This stability control system guarantees pitch and roll rates in order to keep a desired orientation. This system has been developed particularly for application to amateur, multi-stage rockets or rockets with deployable payloads. The control system uses four canards, or winglets, located at the top of the rocket to keep the rocket oriented along its initial launch angle from motor burnout to apogee. The canards are actuated by servos via a custom controller, with the goal of keeping the rocket’s pitch and yaw orientation within five degrees of its launch angle. Initial controller design verification was performed with wind tunnel tests. Final proof of system’s functionality will come from a series of full-scale flight tests. These tests will see the controller fit to a custom-built testbed rocket, dubbed Adiona. Adiona was designed and built using SLURPL’s design methodology, so final success of the flight tests will verify the control system’s performance and demonstrate its applicability to SLURPL rockets in the future.

The group would like to thank their faculty sponsors Dr. Raymond LeBeau and Dr. Srikanth Gururajan for their support of this project.

T. Alex Ambro

Alex is a senior at Parks College majoring in aerospace engineering. Born and raised in Kenosha, WI, Alex can trace his passions for space and rockets back to many hours spent watching Star Wars as a kid and building model rockets with his uncle in middle school. Upon starting at SLU, Alex got involved with the Saint Louis University Rocket Propulsion Laboratory and has served as Director of Payload for the lab since 2018. Next year, Alex is looking forward to continuing his education here at SLU pursuing a master’s degree in aerospace engineering. Outside of academics, Alex enjoys cooking, reading, playing with his dog, and video games.

Aidan Maloney

Aidan Maloney is a senior at Parks College of Saint Louis University studying aerospace engineering. He has always been interested in math and science and was drawn into the world of engineering after attending the Parks College Engineering Summer Acadamy. During his time at SLU, Aidan was involved in the Space Systems Research Lab assisting with the development of research based CubeSats. After graduation, Aidan will be moving to Colorada to work with Lockheed Martin Space.

Andrew Riddle

Andrew is a senior, aerospace engineering student in Parks College of Saint Louis University. He grew up in Greenville, IL and was always interested in things that fly. His fourth-grade teacher was a huge space nerd who greatly influenced his interest in rockets and outer space and helped him build his first model rocket. At SLU, Andrew became involved in the Rocket Propulsion Laboratory and has worked as Co-Director of Structures since 2017. After graduation Andrew hopes to find a job in which he can continue to work with rockets eventually hoping to work on programs that will establish permanent settlements on the moon and Mars. In addition to rocketry, Andrew enjoys playing soccer, listening to and playing music, and studying Spanish.

Jonathan Schaefer

As a senior Aerospace Engineer, Jonathan has been building high-powered rockets for the last 3 years as co-director of structures. Jonathan’s fascination with rockets, satellites, and outer space formed in his hometown Dubuque, IA where he spent countless nights gazing at the night sky. His interest in what lies beyond Earth only escalated after being introduced to the Star Wars franchise by his father. Since then, he has spent more time learning about the lore than breathing. In addition to being a full time Star Wars nerd, Jon enjoys competing for the Saint Louis University varsity cross country and track and field team where he has won two 4x800m conference medals as well as leading a weekly bible study and playing piano in his free time.

Henry Wright

Henry Wright is a senior Engineering Physics student with a focus in aerospace engineering. Henry first got introduced to aerospace engineering in his high school in Nashville, TN when he joined the school’s rocketry club. He and his teacher were the only active participants and they spent their time constructing experimental rockets and motors. His interest only grew after entering SLU and joining the SLU Rocket Propulsion Laboratory. After graduation, Henry will be pursuing his master’s degree in aerospace at SLU.

Parker Krueger

Parker Krueger is a senior studying Engineering Physics with a background in Aerospace. Growing up in Arnold Mo, his interest in the Aerospace industry began in a first-grade summer school class on The Aerodynamics of Paper Airplanes. However, a spark for invention existed from early on with his creative and inquisitive family. His summers were spent repairing cars and constructing new things to play with, from trebuchets to fireworks. Now, with the end of his undergraduate education he will pursue a career in Aerospace and then hopes to continue education on the topic of Magnetofluid Dynamics and Plasma Physics. Some of Parker’s other interests include brewing Mead, Hiking, and Camping.
