Skybox: Innovative aerodynamics

SkyBox Engineering (SBE) is revolutionizing passenger and cargo air transport with innovative aerodynamics. Through years of research, the PrandtlPlane® architecture offers a boxwing aircraft that combines safety, environmental sustainability, and outstanding performance.

The Best Wing System

Ludwig Prandtl has demonstrated in 1924 that the wing system with minimum induced drag for given lift and wingspan is box-shaped with equal lift on the two horizontal wings and butterfly shaped on the vertical wings. The aircraft architecture has been named PrandtlPlane® in honor of Ludwig Prandtl, one of the fathers of moder aerodynamics who first published in 1924 the concept of the Best Wing System (BWS)

The PrandtlPlane® can: Improve the efficiency of air transport, reducing the environmental impact and costs of aviation

The PrandtlPlane® concept is scalable to a large set of applications: UAV or drones for surveillance and rescue, PAV, ULM, eVTOL, STOL, amphibious, freighters, airliners, with enhanced performances.

Products

Engineering excellence, Italian passion: crafting innovative solutions that take flight and inspire the world

Amphibious Airplane

The extreme flexibility of the PrandtlPlane® permitted to design IDINTOS, a 2-seats amphibious airplane for leisure time. The airplane has been designed according to the EASA CS-VLA (Very Light Aircraft) specification, and a full scale prototype together with a 1:3 scaled radio controlled flying model have been built and tested.

Airliner

The scalability of the PrandtlPlane® has been demonstrated during the PARSIFAL project. funded by the EU under H2020 program, is set to offer a leap forward in both efficiency and capacity. By leveraging the box-wing design, PARSIFAL envisions aircraft that are more spacious, environmentally friendly, and cost-effective to operate.

Drones and advanced air mobility

A 9-seats FAR part 23 PrandtlPlane® show a +15% in aerodynamic efficiency compared to the top class reference aircraft. This AIR TAXI means lower consumption, higher range, less noise. The high efficiency is an enabler for the future aviation of this class of aircraft with hybrid-electric propulsion.

Collaborative R&D partnerships

SkyBox Engineering has a proven track record of successful collaboration in international research and development projects, particularly within European Union-funded initiatives.
