03.2 - Experimental AerodynamicsADAPTIVE WING HIGH-LIFT SYSTEMA.V. Petrov¹, A.V. Potapchik¹, J.G. Stepanov¹, V.V. Gubskiy¹; ¹TsAGI, Russia Adaptive high-lift system contains the double-slotted flap deflected. Calculations shown increase the lift coefficient by 15%. Test are shown what the lift coefficient increases by 11–13%. Range of propeller load coefficients ?=0.5?1.5 increases the lift coefficient by 25% and 36%, respectively. Adaptive element facilitates the decision of the problem of longitudinal trimming of the airplane. |
