Control of Aerodynamic Characteristics of a Varioform Sectional Wing

Abstract

Within the framework of this work the concept of using a special system as a bearing surface of new types of aircraft is presented. The concept is based on the use of the varioform-sectional wing (VFS wing) device developed and patented by the authors. This bearing surface consists of a rigid bearing frame and with flexible force elements and elastic cladding. On the one hand, the design of the device allows you to organize the control as a current on the surface of the wing due to what significantly improves aerodynamic performance in the area of critical angles of attack. On the other hand, the system allows to control the deflection of the vehicle trajectory by changing the pressure distribution on the carrier surface. In this case, the aircraft does not need classical articulated-section steering elements and associated drive systems and units. This publication demonstrates theoretical and experimental data confirming the effectiveness of the proposed methods.
