Every component and system in the P180 Avanti II is carefully crafted to provide the highest levels of efficiency and safety under all flight conditions. But the real key to its success is an advanced design with many innovative solutions, the most important of which is the Three-Lifting-Surface Configuration. The forward wing of the aircraft (which cannot be called a true "canard" because it lacks control surfaces) contributes to lift, since it is a fixed surface, and is equipped with high lift devices that move together with the flaps on the main wing. The pitch angle of the forward wing is configured so that it always stalls before the main wing. The resulting automatic nose-down effect assures excellent behavior at high angles of attack. The forward wing has a negative dihedral (~ 5 degrees) to keep its stream wash away from the engine intakes, the main wing and the horizontal stabilizer. Thanks to the aerodynamic advantages resulting from the aircraft's innovative design and construction, the airflow is laminar over a very high percentage of the wing chord. What's more, the push configuration of the propellers prevents propeller turbulence from interfering with wing aerodynamics, which effectively lowers total drag and provides performance that is significantly higher than in aircraft with pull propellers.
The small forward wing is the truly revolutionary innovation of the P180 Avanti II. This amazing design solution significantly reduces weight and drag, which translates into superior performance combined with remarkably economical operation.
A single, continuous aerodynamic curve surrounds the P180 Avanti II from nose to tail to create a perfect profile that maintains laminar flow, thus minimizing drag and maximizing performance.
The overall effect generated by the special architecture and configuration with three lifting surfaces reduces by 34% the surface area of the main wing required for a given payload and offers clear benefits in terms of reduced weight and drag, and higher performance.
What's more, the push configuration of the propellers prevents propeller turbulence from interfering with wing aerodynamics, which effectively lowers total drag and provides performance that is significantly higher than in aircraft with tractor type propellers.
