Maximum Thrust from O3400 Motor
For the first time we will be competing in the 30,000 ft division of AURC with Project Aurora. Unlike the previous Project Astra and current Project Halo which are designed to reach 10,000 ft, launching to 30,000 ft has newfound challenges. For example, supersonic analysis becomes necessary which in turn requires extensive prototyping, testing and systems analysis to ensure a safe launch. Such an undertaking will require an O-class motor and composite materials coupled with a streamlined design to lift the rocket to 30,000 ft.
While the colour scheme reflects the vibrant colours seen in auroras, the rocket’s geometry has been thoughtfully designed to minimise drag and fly effortlessly through the air. A Von Karman profile was chosen for the nose cone and boat tail due to its low drag coefficient during supersonic flight, minimising the forces of aerodynamic drag and hence allowing the rocket to achieve a larger apogee.
The rocket will house a 2U CubeSat and two GPS modules for location determination during the recovery phase of the flight. A temperature sensor will also monitor the nose cone and electronics as the 2210 km/h maximum speed will generate significant heat within the leading edges of the rocket.
The high dynamics leading due to atmospheric resistance will cause significant stresses within the rocket’s structure and hence strong and rigid materials must be selected. The body tube will be manufactured from filament wound carbon fibre epoxy to withstand these forces.
Project Aurora will be propelled by an O3400 motor which as a maximum thrust of 4699 Newtons or 479 Kilograms or pushing force and will produce a total impulse of 21041 Newton-seconds.The propellant itself weighs more than 11 Kilograms and will be needed to push the 2U CubeSat payload to 30,000 ft.
