This paper aims to present a preliminary study on a disruptive vertical take-off and landing (VTOL) configuration based on the best wing system concept by L. Prandtl. A preliminary design has been addressed from several points of views: a conceptual design has been carried out thanks to in-house optimization tool; aerodynamic performances, propulsion design and […]

Overall Preliminary Sizing and Optimization of the Metallic Structures of a PrandtlPlane Civil Transport Aircraft The paper aims at presenting and summarizing the activities carried out on the structural aspects of a box-wing aircraft, called PrandtlPlane, proposed as a more efficient alternative to present commercial aircraft. The results hereby shown represent the major achievements in […]
A new paper published in Aircraft Engineering and Aerospace Technology (Emerald): “Preliminary stability analysis methods for PrandtlPlane aircraft in subsonic conditions”
The present paper aims to assess the reliability and the limitations of analysing flight stability of a box-wing aircraft configuration known as PrandtlPlane by means of methods conceived for conventional aircraft and well known in the literature. Results obtained by applying vortex lattice methods to PrandtlPlane configuration, validated previously with wind tunnel tests, are compared […]
A new paper published in Aerotecnica Missili & Spazio (Springer): “Preliminary design of a Tiltwing UAV with a box wing configuration”
In the last years, aircraft disruptive configurations have been studied on view to increase civil air transport and safety of flight and, also, to reduce air pollution and noise. One of the promising configurations is the so called box wing, based on the Best Wing System concept by L. Prandtl. This paper presents an application […]
A new paper published in Aerotecnica Missili & Spazio (Springer): “Design, Optimization and Manufacturing of Metallic Wings of Light Aircraft”
Most of the wing structures of modern leisure and sport aircraft, such as LSA, VLA, ultralights, etc., are made of composite materials. These latter allow for high surface quality and lower costs, if compared to metallic solutions with conventional riveted technology, which would be adopted as production volumes are small. Assuming a greater production volume, […]
