The car is of hybrid construction with the forward half of the car carbon fibre and the rear section a metallic fabrication
The front section of the car consists of a carbon fibre monocoque, similar in concept to a Formula 1 tub. This provides the driver with a very secure, rigid safety cell. It is also the most efficient way to form the complex curvature at the front of the car ahead of the cockpit and main jet intake.
The rear of the car is a metallic fabrication split along its centreline.
The upper chassis is of a rib and stringer type, typical of aerospace construction. The ribs and stringers are fabricated in Titanium and the outer skin is also Titanium, this has been necessary to reduce the weight at the rear of the car whilst maintaining stiffness.
The upper chassis mounts the Eurojet EJ200, the intake duct and the fin.
The lower section consists of a series of aluminium frames and bulkheads that are skinned in steel. The lower structure mounts the Cosworth CA2010 Auxiliary Power Unit, the jet fuel tank and the rocket system.
The last portion of the lower structure forms the rear subframe and it is on this that the rear suspension mounts, together with the rocket thrust ring and the parachute cans and attachment.
