Next-Generation Chemical Propulsion Systems
ABOUT OUR COMPANY
Protolaunch is developing reliable chemical propulsion systems to enable a future of dedicated launch for small payloads.
For several decades, satellites have been getting smaller while the rockets that launch them have not. Existing launch vehicles are designed for large payloads, forcing this new generation of SmallSats to rideshare on enormous rockets. This is an expensive system of compromise where the secondary payload regularly loses out.
Companies racing to fill the demand for dedicated SmallSat launch are seeking to scale down existing large engine designs and are accepting the added cost and manufacturing complexity this involves.
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. Based on work conducted at the University of Cambridge, Protolaunch has developed a novel thermodynamic cycle that eliminates the need for any turbomachinery while enabling the use of cleaner biofuels, and simplifying propellant handling and storage.
Protolaunch technology leverages thermodynamic optimisations to eliminate the need for complex pumps & turbmachinery and reduce manufacturing complexity.
Our propulsion technology presents a number of strategic advantages over turbomachinery or high-pressure blow-down. Our technology is the key enabler for a dedicated microlauncher and will facilitate a future of dedicated launches for small payloads.
Additive manufacturing techniques enable reduced part counts, mass savings and flow geometries not possible through conventional methods, positioning Protolaunch engines for scalable development.
With few moving parts and vastly lower operating pressures, the reduced complexity of Protolaunch propulsion systems allow for a focus on simplicity at the core.
Our cycle design enables the use of renewable biofuels and eliminates the need for highly refined kerosene.
