Download or read book Investigation of Unsteady Airloads on Wings with Oscillating Control for Active Control Purposes written by W. Geissler and published by . This book was released on 1981 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intensive experimental investigations have been carried out on a wing section with oscillating control including a streamlined gap between both wing parts. Steady as well as unsteady pressure distributions have been measured outside and inside the gap region for various incidences, flap angles and frequencies. In addition to the experimental investigations, a calculation procedure has been developed taking into account the real boundaries of the configuration including the gap region and assuming the fixed wing part and the oscillating control as two lifting systems with two Kutta conditions and correspondingly two wakes behind wing and control. Comparisons between theory and experiment are discussed in detail and the major influences and effects of viscosity are pointed out. The results lead to special conclusions for the applicability of lifting systems for active control purposes. (Author).
