DESIGN
Dumitru always kept design in the highest regard, aiming at the creation of not only functional, but memorable products too
Stabilo
Stabilo was transported by the world's largest solar balloon and launched from the stratosphere where the drag has a significantly lower impact on the vehicle's performance. This was the main reason for which Dumitru chose to a spherical tank and a spherical capsule to save weight. The engine was bolted directly on the tank, with the valves placed directly in the propellant to increase simplicity and offer a streamlined design.
The same solution with the exposed spherical tanks and capsule was used for the Helen 2 rocket which was successfully launched at 40km altitude in 2010, which proved the design's viability.
AirStrato
The AirStrato was a high altitude, long endurance, solar powered, air-robot designed to create a network of high altitude drones to deliver internet access in remote areas.
The aircraft exhibits two prominent sections, at the front and the rear of the fuselage. These sections were used to house receiving and emitting equipment for the network, with a large dish in each section. Besides functionality, these also lead to a beautiful design for the aircraft.
ArcaBoard
For the ArcaBoard, Dumitru focused on creating the smallest possible package for an electric hoverboard able to fly above any terrain.
The challenge to pack inside of a 15cm thick structure a 272 HP propulsion system, the same as a Moto GP was tremendous. It was however a must to create a design as thin and light as possible.
EcoRocket
The EcoRocket is a sea launched rocket which raise specific challenges.
Once placed on the sea surface, the rocket needs to get into vertical position for the launch. Therefore, Dumitru chose to expand the stabilizers under the engine to allow the attachment of the ballast needed for the sea verticalisation. Immediately after the launch the excess stabilizers were to be detached. This created a unique design which was also validated in flight.
