The combustion chamber is where the propellants release their energy. Cryogenic liquids enter the chamber and leave as exhaust gases travelling at supersonic speeds, all while the chamber is exposed to temperatures capable of melting most metals. Designing a chamber that can withstand these conditions while maximising performance is one of the central engineering challenges in rocketry.

The injector plate is where fuel and oxidiser first meet. Precisely machined orifices atomise the propellants into a fine spray, creating the conditions for stable and efficient combustion. Every hole diameter, angle, and spacing influences how the propellants mix, making injector design one of the most important factors in engine performance.

The main valves are responsible for controlling the flow of propellant into the engine. To achieve ignition, they must move to precisely the right position within fractions of a second and in perfect synchronisation. Designing reliable actuation systems that can operate quickly under high pressure is essential for achieving a clean and repeatable engine start.

The feed system is responsible for storing and delivering the propellants to the engine. We design the tanks, plumbing, mounting structures, and connect them with all the components in between - from valves and regulators to sensors and instrumentation. The challenge is ensuring that the engine receives fuel and oxidiser at the correct pressure and mass flow throughout the burn, while keeping the system lightweight, reliable, and easy to operate.
