Abstract

Abstract: Blended-wing-body configuration could be the most promising irregular configuration in the future. The verification of its aerodynamic layout is usually carried out through a scaled model flight test. Using the numerical method, this paper analyzes the instability in both transverse and longitudinal directions during the verification flying test and proposes an improvement plan of adding slat. We designed the aerodynamic layout of the slat for the testing aircraft, and 2D and 3D slat for the typical wing-shape. Results are analyzed on both the transverse and the longitudinal directions through numerical simulation, indicating that the designed slat can significantly enlarge the stall angle of attack and improve the moment characteristics on transverse and longitudinal directions.

Key words: blended-wing-body, civil aircraft, low speed testing aircraft, slat, longitudinal characteristics, transverse characteristics
