Supersonic flight is not without its rigors. Massive aerodynamic forces, compression wave heating, and the tremendous power of Eureka-1's engines all combine to place forces in excess of 12 Gs on internal components. Without a carefully designed internal bracing structure, vehicle skin, and control surfaces, Eureka-1 would crumple under its own thrust. SEB Airframe Division designs the systems that ensure Eureka-1 remains sleek, intact, and under control throughout its flight.



What goes up must come down*, but if you want that journey to be controlled, you need to have some sort of avionics package on board your vehicle. SEB Avionics designs the software and hardware that allows Eureka-1 to communicate with the ground, determine its position in space, modify its flight, and coordinate the timing of key events such as engine ignition, payload separation, and parachute deployment.



Eureka-1's first flight is not focused on the payload, but rather on proving the viability of the system for future missions. However, SEB Payload Division still plays a vital role in ensuring that no flight is wasted, and every launch brings back useful scientific data. For our upcoming launch, SEB Payload Division is independently developing a life sciences experiment intended to be run in the high atmosphere.

In the future, SEB Payload will coordinate with clients to plan their flights, integrate their payload, and deliver the final results.



The Ascella engine sits at the heart of Eureka-1, and the dedicated members of SEB Propulsion Division are tasked with designing not only the engine system, but the fuel tanks, pressurization systems, valves, and piping that combine to loft Eureka-1 higher than any amateur rocket before it.



Without a functional recovery system, Eureka-1 would not be able to return viable data from space. SEB Recovery Division is tasked with ensuring the nose cone, avionics bay, payload, and associated equipment returns to Earth's surface at a safe velocity. Through careful application of aerodynamics, kinematics, and mechanical engineering, the Recovery Division brings the speed of the returning payload from Mach 2 down to a gentle 3 m/s (6.7 mph).
