Hybrid rocket motors for European defence
Non-explosive, COTS-based rocket motors for CUAV and loitering-munition integrators
The Technology
Hybrid rocket motors
Our hybrid rocket motors use paraffin wax and nitrous oxide, two common industrial materials. The two only meet inside the combustion chamber. A pressurised tank keeps the motor firing reliably in hot and cold conditions.
Inert until fuelled
No explosives licence anywhere in the supply chain. Storage, transport and integration stay outside explosive handling regulation.
Throttleable
Solids cannot throttle, with the mix of our fuel and oxidiser the hybrid rocket motor can.
Off-the-shelf components
COTS by design. Fuel and oxidiser are widely available chemicals, unlike solid propellants.
Use case
Where the motors go.
01
Main motor for missile systems
Integrated into the airframe as the primary propulsion of a missile system. The motor is designed around the customer's platform, delivering controlled thrust across the full flight profile.
02
Rocket-assisted take-off booster
A bolt-on boost stage that lifts drones and missiles to flight speed and altitude with rapid deployment using limited space. Jettisoned after burnout, leaving the platform to fly its mission.
Product Catalogue
The motor range.
Five motors covering light UAV to heavy-platform rocket-assisted take-off. Each unit is built around the customer's airframe and mission.
