RECORD-BUSTING MOTORBIKE WILL BE JET ENGINE ON WHEELS
The approach to moment the motorbike land speed record may be to put a jet engine on two wheels
RICHARD BROWN is a man with unprepared business. In 1999, he crushed the one-way speed record for a motorbike by hitting 584 kilometres per hour on the salt flats of Bonneville in northern Utah. But his explain on the undisguised world record – which is based on the normal of two runs in conflicting directions – was thwarted by technical problems.
Now he is perplexing again. He hopes to be the first person to surpass 720 km/h on a motorbike whilst achieving an normal two-way speed of at slightest 640 km/h. Any aged bike will not do: he will be using a single that is jet-propelled.
While cars used in land-speed-record attempts, identical to the Bloodhound jet automobile that will try the challenge in 2012, and certain types of vessel have taken value of jet bearing given the 1950s, all record-breaking motorbikes have used a required engine that drives the behind wheel.
This is given it is formidable to container a jet engine into a two-wheeled await able of huge speed with any grade of safety. Fast cars can be built around aged jet warrior engines, yet these are distant as well complicated to fit in to a bike that contingency be offset by the driver creation little steering adjustments to the front wheel.
So for his brand brand brand brand brand new bike, called Jet Reaction, Brown has redesigned a 930-kilowatt helicopter engine to furnish bearing instead of branch a rotor. It was “quite difficult”, he says. “One is operative with really excellent tolerances in really formidable materials. If you get it wrong, destroying the engine is the many expected result.”
Brown has also added his own reheat unit, or afterburner. It sprays fuel in to the prohibited empty gases, causing it to light and beget nonetheless more thrust. The thought sounds elementary enough, yet he says that removing it to work at something coming the fanciful intensity “requires most more development”. The reheat burner sits on top of two canisters that muster braking parachutes when needed.
Brown has a track record in desirous jet engine projects. Following his 1999 record try he built a sub-orbital rocket, yet the launch in South Africa had to be cancelled. He is also operative on a gas-turbine-powered jet pack, identical to a single grown by the US military, that he hopes will concede the wearer to sojourn airborne for 10 minutes.
Brown’s 1999 record try concerned his own Gillette Mach 3 Challenger bike, which featured a custom-built hybrid space station engine. The try unsuccessful given soothing belligerent forced the group to use tyres rsther than than the common aluminium wheels. The tyres were usually written to ward off speeds of 380 km/h or so. Eventually the large centrifugal forces on the behind tyre caused it to deflate.
The stream motorbike land-speed record, 606 km/h, was set in 2010 by Rocky Robinson on a bike called the Ack Attack Streamliner. Such record-breakers underline elongated steel bodies – as does Jet Reaction – creation them demeanour more identical to hulk bullets than motorcycles. They are also propitious with retractable stabilisers for change when relocating solemnly or stationary.
Brown expects to lift out trials with Jet Reaction at a UK airport in Mar subsequent year, with an try on the universe record behind at the Bonneville salt flats pencilled in for 2013.
It won’t be easy, says Mark Chapman, Bloodhound’s arch engineer. “The greatest emanate is air intake,” he says. “You have to be sure the air flow through the jet is fast or the engine could surge, which could be dangerous.”
