context_page_description: Bloodhound LSR, formerly Bloodhound SSC, is a British land vehicle designed to travel at supersonic speeds with the intention of setting a new world land speed record. The arrow-shaped car, under development since 2008, is powered by a jet engine and will be fitted with an additional rocket engine. The initial focus is to exceed the current speed record of 763 mph in 2020 or 2021, with the vehicle believed to be able to achieve speeds up to 1,000 miles per hour.
  Driver Andy Green will attempt to break his own record set in 1997. The previous business behind Project Bloodhound went into administration in late 2018. Entrepreneur Ian Warhurst bought the car to keep the project alive. A new company called Grafton LSR Ltd was formed to manage the project, which was renamed Bloodhound LSR and moved to SGS Berkeley Green University Technical College.
  The venue for high speed testing and future world land speed record attempts is the Hakskeen Pan in the Mier area of the Northern Cape, South Africa. An area 12 miles long and 3 miles wide was identified as suitable, with hand-clearance of rocks by local volunteers before track markings could be applied, with the first runs in October 2019.
context_section_description: Three prototype Eurojet EJ200 jet engines developed for the Eurofighter and bound for a museum were loaned to the project. The car will use one EJ200 to provide around half the thrust and power the car to 650 mph (1,050 km/h). A custom monopropellant rocket designed by Nammo will be used to add extra thrust for the world land speed record runs. For the 1,000 mph (1,600 km/h) runs, the monopropellant rocket will be replaced with a hybrid rocket from Nammo. A third engine, a Jaguar supercharged V-8 is used as an auxiliary power unit to drive the oxidiser pump for the rocket, although this will be replaced by an electric motor.
  Initially Bloodhound SSC was going to use a custom hybrid rocket motor being designed by Daniel Jubb. The rocket was successfully tested at Newquay Airport in 2012. However, constraints on cost, time and test facilities led to a decision to instead use a rocket designed by Norwegian company Nammo.
  At first the plan was that the car would use a Nammo hybrid rocket or cluster of rockets, to be fuelled by solid hydroxyl-terminated polybutadiene and liquid high-test peroxide oxidiser. This plan was revised in 2017 and the car will use a monopropellant rocket for the land speed record runs.
  
  For the car to achieve 800 mph (1,300 km/h), the monopropellant rocket would need to produce around 40 kN (8992 lbf) of thrust and the EJ200 jet engine 90 kN (20,232 lbf) in reheat.
