The Challenge:

Our aim is to set a world record above 1000MPH (1600KM/H) or Mach 1.4 which is well above the speed of sound. At sea level the speed of sound is approximately 1225 km/h or 760 MPH. Our unique vehicle will require multiple runs to test and refine the car. Some current world records will be broken on our adventure to reach the holy grail of motor racing. Our car needs to be checked, re-fuelled and turned around to run in the opposite direction in under one hour to set a world record (the speeds of the two runs through a Kilometre and Mile are averaged). 

Design Principles:

The overall principle of AI5R is KISS (Keep it SAFE & SIMPLE) which states that "most systems work best if they are kept simple". For example, the main body of the AI5R started as a rolled and dimpled 12 metre length of 914mm diameter 10mm thick steel pipe. The dimples were formed in unicum along the length of our mainframe to create a boundary layer of air that clings to the car and reduces aero drag. This mainframe is naturally quite rigid so, apart from separation bulkheads, no further internal bracing was required. The rollcage has heavy walled, forward and aft, hollow bar sections which also support the cutout area of the mainframe where the driver sits. With its nose cone, front suspension & wheels pack removed the car fits neatly into a standard 40' shipping container so that it can be easily and safely transported to any location in the world. 

Vehicle Specifications:

Length: 16 metres
Height: 2.5 metres ground to top of the tail fin
Width: 2.3 metres rear track
Weight: 6 tonnes dry and 9 tonnes fully loaded (i.e. she carries 3 tonnes of propellants)

The car is deliberately built heavy to keep acceleration forces down to around 3G to allow the wheels to stay in synch with the rate of acceleration that the chassis is undergoing. 


0-1000MPH (1609 KM/H) in 20 seconds


These were produced by Calm Aluminium using 7075 grade aerospace aluminium. They are 915mm in diameter x 198mm wide and weigh 140kg each. At 1000 MPH the wheels will be spinning at over 10,000 RPM and will undergo centrifugal forces of 50,000 G at the periphery of the wheel. 

The Rocket Motor:

Our motor is known as a B3 bi-propellant liquid rocket motor with several static tests performed at the Mojave Rocket Range in California. The motor produces 62k lbf force or the equivalent of 200,000 horsepower (149,139 Kilowatts) making Aussie Invader 5R the most powerful car ever built. The huge amount of power needed to get us to our design target means one of our biggest R&D issues is overcoming the car's launch inertia without the motor tearing itself out of the chassis. Apogee Rocket Motor Systems P/L has been tasked with overcoming the launch inertia issues and also perfecting a horizintally firing bi-propellant rocket motor. 

Currently under development are two motor options - (1) using liquid oxygen as an oxidiser and Jp-1 as our fuel, force fed through an Atlas ICBM injector using our own-design gaseous Helium system and (2) a 90% Hydrogen Peroxide catalyst method to our HTP/JP-1 injector or Apogee pintle injector. This HTP motor will have the ability to be a switching stage motor and be hypergolic, whereas we cannot achieve hypergolic ignition with our lox/JP-1. Another plus for HTP/JP-1 is that our blowdown gas can be gaseous nitrogen.


As the rocket motor is shut down at high speed a huge amount of drag will rapidly reduce it's Mach number to M+1.1 and generate a very high negative G. Once our car has stabilized through this aero drag onslaught and our wheels have regained traction, bringing them into synch with the car's chassis, our air brakes will then be deployed. A highspeed braking chute is then fired from the rear of the car bringing her speed down to Mach 0.66. A low speed chute is then fired to stabilize and slow our car down to 200 MPH (320 KM/H). The car is then brought to a standstill with the application of her wheel brakes and in the event of a chute deployment failure we have a ground brake that penetrates the playa surface. Should our car be in a Code RED situation, where she is still travelling too fast, an aircraft style catch cable buried at each end of our race track playa will contact our ground brake and bring our car to a standstill. 

Where will the Aussie Invader run? 

A few options are being considered and this is still to be decided by the support we can gain via sponsors and local support. The car is designed to run on a smooth, dry mud surface (not salt). The track ideally needs to be 30km long and 1km wide. 

Our 3 most likely options already explored include Diamond Valley Nevada USA, the Bilpa Morea Claypan Western Queensland and the base of the Cockburn Ranges in Western Australia. 

Why do this? 

Setting a World Land Speed Record for Australia is Rosco McGlashan's life's work and obsession which first started at age 12. His contribution towards putting Australia on the world stage showcasing his team's mammoth amount of desire, dedication, determination, ability and guts is unprecedented. This seemingly impossible endeavour is not about an ego trip for him or his team of extremely loyal volunteer crew members, it's all about proving to our youth that "achieving the impossible" means not quitting!
