First UK hybrid rocket engine


Bletchley, a nuclear fusion business, has designed and tested a high-power chemical rocket engine that is ready to be launched. Bletchley’s long-term goal is to develop a hyper-speed propulsion engine for interplanetary travel utilising nuclear fusion technology. It has been said that this development has the potential to reduce the transit time to Mars by half.

A series of successful tests exemplifies the company's quick design, development, and testing of high-performance technical components. The rocket engine proudly flashed the Union Jack flag when it was launched.

“ It is a hugely significant moment and we are proud this rocket is built in the UK“

Richard Dinan, chief executive officer, said “We are delighted with the UK test firings at COTEC. It is a hugely significant moment and we are proud this rocket is built in the UK. To have a British rocket test on UK soil is novel.”

The non-toxic hybrid rocket engine burns nitrous oxide oxidizer, high-density polyethylene fuel, and oxygen to produce thrust. It is a revolutionary model that allows the business to produce rocket engines incredibly quickly, with a higher level of safety compared to traditional liquid propulsion engines.

When being tested, the first ‘green’ high powered rocket engine only calls for management of one fluid (a liquid oxidiser). A control valve directs the flow of liquid oxidiser into a combustion chamber with patented technology.

Pulsar Fusion got its financing from the UK government in September of this year. This will be invested into the continuous development of its HET (Hall Effect Thruster) plasma satellite engines, which can achieve particle exhaust speeds of 20 km (about twice the cruising altitude of a commercial jet) per second. These Pulsar thrusters are capable of resisting 20g of vibration, imitating a rocket launch.
