The initial testing justified all expectations in terms of aerodynamic characteristics and performance, unfortunately on the third flight the pilot was unable to lower the landing gear and had to land with the undercarriage extended, damaging the propellers and engines.

The aerodynamic characteristics become apparent to the greatest extent at speeds on the order of Mach 0.85 . The airplane s aerodynamic quality at such a cruising speed equals 10 instead of the 6 7 in modern airplanes, V . Klimov emphasized.

"' NACA Report No . 964-The effects of variations in Reynolds number between 3.0 x 10 6 and 25.0 x 10 6 upon the aerodynamic characteristics of a number of NACA 6-series airfoil sections "'was published by the United States National Advisory Committee for Aeronautics in 1950.

Now the wings were covered with cardboard to the half swing instead of cloth which resulted in an improved overall stiffness of the aircraft . This also enabled the landing gear and aerodynamic characteristics of new aircraft to be upgraded, while the weight was only slightly increased.

Single-engine airplane types certified in the normal category must be demonstrated to recover from a spin of at least one turn, while single-engine aircraft certified in the utility category must demonstrate a six turn spin that cannot be unrecoverable at any time during the spin due to pilot action or aerodynamic characteristic.

Losing power in an engine shortly after takeoff, which apparently happened to the plane that crashed near Centennial Airport, presents unusual challenges to any MU-2 pilot because of the aircraft's special aerodynamic characteristics, said John " Rusty " Allman, a Texas lawyer whose firm has represented the heirs of those killed in crashes of Mitsubishi aircraft.

Basic aerodynamic principles dictate that the downforce created by air pressure on a surface increases exponentially with speed, thus, as with many aerodynamic modifications the bumper canards are primarily suited to the high speed conditions of GT Cars where the car s essentially stock bodies ( designed for road-use ) have not already been designed to provide optimum aerodynamic characteristics for track use.
