Simpson Aerospace

Engineering with intent. Built to light.

The practice of Dr. Christopher R. Simpson — a propulsion and state-estimation engineer. Research, published work, and short courses in propulsion and astrodynamics.

Research

Advanced propulsion and combustion — rotating detonation engines, scramjets and combined-cycle systems, combustion stability, and alternative fuels. State estimation and mission planning for responsive launch of small-satellite constellations. Studied at the level of theory, published literature, and open code.

Teaching

Instructor-led short courses. The Orbit Determination course is published here in full; hypersonic propulsion, combustion stability, detonation, and shock tubes are in development. Start the Orbit Determination course →

Open tools

On-Demand Launch (ODL) mission planning, ground-station development on the SatNOGS network, and trajectory and launch-window tooling — developed in the open.
