Analysis of the pre-rotation engine loads in the autogyro

Czyż Z., Łusiak T., Czyz D., Kasperek D.

Advances in Science and Technology. Research Journal

2016

Vol. 10, nr 31

169--176

The paper presents the analyzes of the pre-rotation engine loads in the Taurus autogyro manufactured by Aviation Artur Trendak from Poland. Based on the NACA-9 H-12 airfoil characteristics of the drag coefficient, on which the rotor blade was made, forces acting on the rotor during pre-rotation have been calculated. The paper presents the characteristics of the drag coefficient as a function of angle of attack for Re = 1,800,000 and Re = 2,600,000. For the speed range of 0 to 400 rpm torque resulting from the drag forces and the power required to drive the rotor were calculated.
