Protolaunch is a chemical propulsion company changing the way rocket engines are designed to enable future small launch vehicles.

Profile Description

Satellites are getting smaller while the rockets that launch them have not.  A new generation of microlauncher vehicle is on the horizon targeting <1000kg payloads. Smaller rockets need smaller engines.

Reducing the size of engines intended for much larger vehicles results in spiralling complexity and cost.

​Protolaunch is taking a different approach.

Protolaunch has taken a bottom-up design philosophy to propulsion development, designing specifically for small payloads from the outset. Our technology leverages a new thermodynamic cycle and system-level optimisations. This eliminates the need for complex pumps & turbmachinery,  reducing manufacturing complexity and vehicle weight savings.

​Positioned as an engine supplier, Protolaunch works with launch partners to bespoke our standard propulsion units for particular customer use cases.

​Our propulsion technology presents a number of strategic advantages over turbomachinery or high-pressure blow-down and is a key enabler for a dedicated microlauncher to facilitate a future of dedicated launches for small payloads.

​The core technology is protected through UK Patent Application No: GB2102545.7
