0 - 1000 MPH IN 20 SECONDS

The work in building Aussie Invader 5R is now in full swing, with preliminary planning and design work having taken a decade before the build could start. The science and technology behind such a project is staggering and only now is some of that coming into the reach of people like us, a dedicated and committed small team, driven with a passion to achieve the seemingly impossible.

Rosco McGlashan OAM leads the team, and is also the driver of Aussie Invader 5R. Rosco has 45 years in the Land Speed Record environment, chasing records and becoming the Fastest Aussie on the planet, having driven Aussie Invader III to a one way pass of 638 mph (1,028 km/h) in 1996.

Our wheel rating at maximum velocity is a major concern; we do not want to exceed their safety margins and must limit the wheel speed to 10,000 rpm +/- 5%. At these speeds there is a massive force exerted on the wheel rim (50,000 G) and the wheels have been designed to withstand these forces.

The car should exit the mile in well under four seconds and then the fun begins. The driver will have to shut the down the motor in stages, otherwise the car and driver will experience a negative G of such high proportions, that the driver would black out and it would send the wheels into a frenzy searching for traction. For safety, the motor will be reduced to half throttle to maintain driver control and traction and then reduced further as the car slows, allowing air brakes, parachutes and more conventional braking systems to assist the stopping process.

Throttling down our motor in stages adds extra distance to bring this “missile” to a standstill. It then has to be turned around, towed back to the staging point for the mandatory return run. We then need to re-fuel, re-oxidise, recharge our nitrogen tanks, pack chutes and do a total check over before doing it all again within one hour. The combined average speed in both directions hopefully establishes a new World Land Speed Record… simple really!
