The indoor propulsion test facility within the School of Engineering and Computing has a hybrid and bipropellant rocket test facility. The facility is used for propulsion testing of systems up to the low kN trust range and can provide a range of high-quality evaluation and data analysis options.

The Kingston University London indoor propulsion test facility is an indoor blast chamber that allows for the testing and research of small to medium sized propulsion systems (up to low kN thrust levels). The facility can withstand a 120g TNT equivalent blast whilst firing a system with an overpressure of 3 psi, whilst an extraction system is removing around 3m³ of air a second.

The facility has been designed to operate propulsion systems that operate with a maximum pressure of 70BarA. Current approved oxidizers and/or flammable propellants, with maximum flowrates (as dictated by insurance purposes) include:

To add additional oxidizers or flammable propellants to the approved list will cost a one-off payment of £10k for a full safety report (conducted by an industrial subcontractor).

Restriction on propellants are based on the by-products produced and are reviewed on a case by case basis. Generally, carbon dioxide, water and carbon monoxide are currently acceptable by-products.
