Research on Circulation Control System Design of Rotor/Wing Based on CFD
Publication: Journal of Aerospace Engineering
Volume 36, Issue 1
Abstract
For the canard rotor/wing (CRW) aircraft, the elliptical wing with blunt trailing edge poses challenges to control surfaces and flap design. Based on the characteristics of CRW aircraft, an active circulation control (CC) system was introduced for aircraft control and lift enhancement. The control system was designed and investigated based on numerical simulation. A benchmark problem was used to validate and calibrate the numerical simulation method of circulation control. Design parameters of two-dimensional (2D) circulation control system was determined by variant parameter analysis. A circulation control curved surface was optimized based on the above design parameters, and a well-performed 2D flow control system was achieved. Finally, the 2D design configuration was scaled and lofted to generate the three-dimensional (3D) circulation control wing (CCW). The 3D flow control wing was evaluated and analyzed. The results showed that the flow control concept was effective and can meet the lift enhancement and manipulation requirements of the CRW aircraft.
