From custom phenolics to the first and largest student-built fully composite solid rocket motors, composites are the backbone of SRL’s technologies. Tremendous R&D effort has gone into scaling manufacturing while refining part quality for our flagship project Spaceshot. We are working to implement a 2-week Spaceshot production cycle via flexible tooling and tight process control.

4-axis CNC Filament Winder
This is the machine that makes the machine. Designed in-house, it will replace our current 2-axis commercial winder we’ve been reverse engineering for 3+ years. Starting from scratch gave us the opportunity to create a system capable of evolving in a rapid feedback loop with our vehicle and propulsion technology. It will be responsible for producing
- Airframe sections up to 15′ long/18″ diameter
- R-class solid rocket motors
- Carbon overwrapped pressure vessels (COPVs)
- Liquid engine nozzles
Additionally, interchangeable tooling will enable us to machine radial holes and slots, finish part surfaces, and perform automated welds. Integrating a plethora of tooling into a single CNC machine pushes more manufacturing effort into software. More software defined manufacturing complexity results in a higher degree or quality control. Our software stack is comprised of:
- CADWIND for wind toolpath generation
- Custom gcode generator machining and welding operations
- Mach4 for machine interface and motion control
Our motor casing and airframes are wound on cylindrical mandrels which have to be removed from the finished part post-cure. This process grows more difficult as the mandrels see more use and lose their concentricity. Our mandrel extractor, also known as “The Negotiator”, uses a set of hydraulic jacks to pull the mandrel out from the cured composite.
