Abstract
In the last few years, the interest towards solar powered aircraft has increased significantly for high altitude and long endurance (HALE) missions. Unmanned aircraft (UAV), which stay aloft for many months at 20000-30000 m of altitude, can be a less expensive alternative to present satellites, for munication, remote sensing, surveillance and control, both in civil and military field.
In a previous study, carried out at the Department of Aerospace Engineering of Pisa, a mathematical model has been set up and four different aerodynamic solutions have pared: a wing-tail configuration, a flying wing, a twin boom and a biplane with vertical link-wings (see Figure 1) [1].
As a preliminary results, it has been found that the biplane solution can provide an high aerodynamically efficient aircraft and, at the same time, a stiff structure. The lifting system of this kind of aircraft derives from the Prandtl’s Best Wing System[4], hence the aircraft has been called PrandtlPlane-Solar (PrP-Solar).
