Firehawk Aerospace aims to revolutionize rocketry with safe, cost-effective hybrid engines – TechCrunch

While SpaceX and its ilk in the commercial rocket launch market have changed the economics of space and ushered in an era of small satellite entrepreneurship, the actual rocket engine technology they use isn’t that different from what was in use 50 years ago when NASA was making its first forays into outer space.

Firehawk Aerospace, a new startup founded by CEO Will Edwards and Chairman and Chief Scientists Ron Jones, wants to change that with a stable, cost-effective hybrid rocket fuel that employs additive manufacturing (industrial-scale 3D printing) to overcome the hurdles and limitations of previous hybrid fuel engine designs.

Hybrid rockets themselves – ones that use a combination of solid fuel and liquid oxidizer – aren’t new, but they have always faced significant limitations in terms of their performance metrics and maximum thrust power. Jones, a longtime rocket propulsion researcher and aerospace structures and advanced composite engineer, has been fascinated with engine technology and how to overcome the limits of past hybrid engine designs, while also retaining the benefits – including safety and cost.

Jones had been very interested in physics and engineering through high school and college, but ultimately joined the Navy and became an aviator before later coming back around to working in the aerospace industry. Meanwhile, he took advantage of the advent of the internet in its early days to begin diving deeper into his early love of rocketry, specifically researching hybrid engine technology and trading notes
