Revving up to a new speed record in the Kalahari

A loud hiss rips through the stillness of southern Africa’s Kalahari Desert. It sounds like a fighter jet flying low over the Hakskeen Pan, an isolated dry lake bed in South Africa’s Northern Cape province, near the Namibian border.

Then a thick cloud of sand appears on the horizon, growing steadily as it draws near.

In the blink of an eye, a racing car shoots by with a deafening screech and pelts toward the opposite end of the salt pan.

The “Bloodhound” is gearing up to try to break the current land speed record, which stands at 1,223.657kph.

There is still a way to go before the super racer is ready for that attempt, but today, driver Andy Green is pleased.

“We have reached 904kph,” he says, beaming as he lifts himself out of the cockpit, helmet in hand. “First thing in the morning, plenty of thrust, nice calm wind, so the car ran absolutely straight.”

The British-built Bloodhound stands sleekly behind him, dust still hovering in its wake. The white parachute that helps it brake lies crumpled on the cracked ochre soil.

“Good parachute deployment,” adds the Briton, as the vehicle is towed into a large air-conditioned tent nearby. “That’s pretty much the perfect run.”

The Bloodhound was designed exclusively for speed — the team hopes, if possible, to get up to 1,609.34kph.

The vehicle resembles a wingless jet on aluminum wheels, with a long white body topped by an engine and a stabilizer. Its design is way ahead of the bullet-shaped electric car in which French aristocrat Gaston de Chasseloup-Laubat set the first land speed record on Dec. 18, 1898 — pushing the vehicle’s spoke wheels to 63.15kph.

“You can call it that, a jet engine with wheels, but it’s far more sophisticated than that,” Bloodhound operations head Stuart Edmondson said.

Chief engineer Mark Chapman described the racer as “part Formula 1” and “part jet fighter.”

“The car, as it is a car, has a steering wheel, has a throttle pedal, has a brake pedal,” he added.

The engine, built by Rolls-Royce, once powered a British Royal Air Force (RAF) Typhoon fighter jet.

It was recycled from three decommissioned versions of the Typhoon’s engine, released by the British Ministry of Defense, “without the handbooks,” a Bloodhound team member said, chuckling.

“It’s a car designed to go at 1,600kph,” said Chapman, adding that at top speed, it would be almost 400kph faster than a Typhoon at the same altitude.

“The big issues were aerodynamics, keeping it on the ground,” he said. “You don’t want it to be a plane.”

As the engine’s nine tons of thrust are still unable to break the sound barrier, Chapman and his team plan to give it a boost with a rocket engine.

Green is not intimidated by the prospect. The 57-year-old RAF pilot has held the current land speed record since 1997.

“It’s a very different sensation,” to flying a fighter jet, Green said. “A very different environment ... [and] vehicle.”

The skills and the second-by-second decisions needed to stay in control are like flying a jet fighter “at the limits of its performance,” he said, adding that the main difficulty was keeping the land vehicle steady.

“The car starts to move around at about 300kph — at 350kph, it starts to almost skate on the surface,” he said. “It’s like driving on hard packed snow in a normal car.”

At such high speed, the slightest mistake or technical glitch can be fatal.
