Propulsion R&D Division

Designing cutting-edge propulsion isn't easy. However, HSL’s Propulsion R&D Division is here to research, design, and test those systems like never before.

Propulsion Division Lab Work

Overview

In the Propulsion R&D Division at HSL, we focus on innovating a new era of propulsion solutions for small satellites. Our team dives deep into research and testing, working on various propulsion technologies including resistojets, electrospray thrusters, and chemical propulsion systems. From large scale trade studies to complex design manufacturing, this is where we push the boundaries on the propulsion for tomorrow.

Primary Objectives

  • Design and implement efficient propulsion systems that meet the size, weight, and power constraints of small satellites
  • Research novel propellant options with emphasis on safety, storability, and performance
  • Develop robust testing methodologies to validate thruster performance in simulated space environments
  • Collaborate with other divisions to ensure propulsion systems integrate within their mission parameters
