Bloodhound SSC is a British supersonic land vehicle currently in development. Its goal is to match or exceed 1,000 miles per hour (1,609 km/h) achieving a new world land speed record. The pencil-shaped car, powered by a jet engine and a rocket engine is designed to reach 1,050 miles per hour (1,690 km/h). It is being developed and built with the intention of breaking the land speed record by 33%, the largest ever margin.
A prototype Eurojet EJ200 jet engine developed for the Eurofighter and bound for a museum, was donated to the project. This will take the car to 300 mph (480 km/h), after which a bespoke hybrid rocket designed by Nammo will boost the car up to 1,000 miles per hour (1,609 km/h). A third engine, a Jaguar supercharged V-8, will be used as an auxiliary power unit and to drive the oxidizer pump for the rocket.
Development testing of the initial Bloodhound SSC hybrid rocket motor was conducted by Daniel Jubb of The Falcon Project with tests conducted in 2008-2013. Publicly disclosed tests were conducted in 2009 and 2012 including a run at Newquay Airport in GB. In addition Daniel Jubb designed, manufactured and test fired a full diameter 18" monopropellant HTP thruster for the subsonic ground tests for Bloodhound SSC. "The Bloodhound team had been developing its own hybrid power unit in collaboration with Manchester based Falcon Project Ltd, and gave this rocket its first UK test firing in October 2012. And although this demonstration was deemed a success at the time, it became clear that considerable sums of money and time would be needed to perfect the design." "Nammo will have test firings next year in Raufoss and when we get the data off those we can decide on precisely what the packaging requirements will be," said Mr Chapman, Bloodhound's chief engineer.
The Nammo hybrid rocket will be fuelled by solid hydroxyl-terminated polybutadiene and liquid high-test peroxide oxidiser.
In order to accelerate the Car to 800mph, the monopropellant rocket will produce around 40kN (8992 lbf) of thrust and the EJ200 jet engine will make 90kN (20,232 lbf) in reheat. For the 1,000mph runs, the Nammo hybrid rockets will provide a thrust of 123.75kN (27,820 lbf), generating about 212kN (47,659 lbf) in total
