This programme evaluated the suitability of using CuCrZr for additively manufacturing rocket engine combustion chambers, under a UKSA Pathfinder grant with maunfacturing partner 3T AM. Small test pieces were printed in CuCrZr to analyse the flow properties of various printed geometries. These included a full combustion chamber and injector head …

As part of a global drive to move towards less toxic propellants, Nitrous Oxide Fuel Blends (NOFB) have been identified as a potential monopropellant to replace hydrazine. These have high performance and the potential to be long term storable, but little is known about their combustion performance or long-term storability …

The Stoic engine was designed as part of the Advanced Nozzle programme by Reaction Engines under ESA funding. The Stoic engine has many subscale features of REL Sabre engine concept, most importantly that it has two combustion chambers for both air-breathing and rocket modes, and the ability to change between …

If rocket propellants can be made on Mars then huge savings can be made in vehicle size for return missions. This UKSA funded programme studied the combustion performance of various propellants that could be made in-situ on Mars, and studied the performance of the injection system. Propellants included oxygen, carbon …

The STRICT engine evaluated the altitude compensating performance of an expansion-deflection nozzle using hydrogen and air propellants. This was a direct follow-on from the STERN programme, but with higher massflows and total thrust. It required careful measurement and control of the propellant massflows and high-speed measurement of nozzle wall-pressures to …

The Static Test Expansion-deflection Rocket Nozzle (Stern) engine was a 5kN gaseous hydrogen-air rocket engine with an expansion-deflection nozzle and a copper heat-sink chamber. It was tested in both cold and hot flow conditions. The experiments were designed to test the altitude-compensating performance of a nozzle with this geometry, which …
