# Simpson Aerospace - **Website:** - **Primary alias:** `simpsonaerospace.com` ## Description Simpson Aerospace is the engineering practice of Dr. Christopher R. Simpson, focused on propulsion, state estimation, and astrodynamics. Its guiding principle, “Engineering with intent. Built to light,” reflects a body of work centered on research, published writing, open tools, and technical education. The practice explores advanced propulsion and combustion topics, including rotating detonation engines, scramjets, combined-cycle systems, combustion stability, and alternative fuels. It also investigates state estimation and mission planning for responsive launches of small-satellite constellations, drawing on theoretical study, published literature, and openly available code. Simpson Aerospace offers instructor-led short courses, with a complete Orbit Determination course available online. Courses on hypersonic propulsion, combustion stability, detonation, and shock tubes are in development. Its open engineering tools include On-Demand Launch mission planning, ground-station development through the SatNOGS network, and trajectory and launch-window resources. The site also shares articles on orbital mechanics and responsive constellation launch planning, alongside research and educational materials for people interested in aerospace engineering. ## Industries - 🏭 Heavy Industry and Engineering - 🏭 Aerospace and Defense _(under Heavy Industry and Engineering)_ - 🧪 Science and Education - 🧪 Physics _(under Science and Education)_ ## Logos & icons - logo _(primary)_ — PNG — [download](https://cdn.brandfetch.io/idLJgHfeT2/w/180/h/180/theme/dark/logo.png?c=1bxid64Mup7aczewSAYMX&t=1792862990893) ## Colors | Name | Hex | Theme | | --- | --- | --- | | Crimson | #c8102e | accent | | Cod Gray | #0a0a0a | dark | | White | #ffffff | light | ## Fonts - Helvetica — asset _(custom)_ --- _Source: _ _See [/llms.txt](/llms.txt) for a full list of agent-readable pages, and [/auth.md](/auth.md) for how agents authenticate._
