What it is about for Brown is the engineering challenge of building a machine that goes that fast. “I’ve always been fascinated by propulsion and by how things work,” he said. “It’s the puzzling things out that really interests me, the solving problems.”
Brown is at a British equivalent to the American salt flats synonymous with land speed records this weekend, to tweak and test his machine. When the tide sweeps out at Pendine Sands in Carmarthenshire, south-west Wales, it leaves – as long as the wind is helpful – a long stretch of flat sand.
In 1924, Malcolm Campbell here in his Sunbeam 350HP car, Blue Bird. Earlier this month, the actor on Pendine in a Bentley Continental GT Speed. This weekend speed fans descended to whizz along the beach on modern and vintage motorcycles and souped-up cars.
The Jet Reaction is a league above even those customised vehicles, it is propelled by the sort of engine more usually found driving a Sea King helicopter’s rotor blades. Brown redesigned that engine so it would provide the forward thrust needed. He built a bespoke jet pipe that could jink past the rear wheel and added an afterburner to give the extra kick needed. Stopping is another problem – first a parachute is released to slow it down, before a rear-wheel brake can bite.相关的主题文章：
