1 Civil-transport wing design concept exploiting new technologies Prasetyo Edi * Aerospace Engineering, University Putra Malaysia, Serdang, Selangor DE., 43400, MALAYSIA J. P. Fielding † Aerospace Engineering Group, Cranfield University, Cranfield, Bed’s MK43 0AL, UK Current trends in the design of transport aircraft have shown that in order to be economically viable and competitive it is necessary to investigate technologies which may give an improvement in performance and operational flexibility goal, but must be shown to be cost-effective. The current competitive environment forces the airlines to buy advanced technology aircraft and requires manufacturers to provide more operational flexibility, without drastic performance penalties. This is a challenging task, which might be solved by the use of new technologies. It is believed that the application of a Hybrid Laminar Flow Control (HLFC) and Variable Camber (VC) to a wing would assist in achieving such a task. This paper describes an investigation aimed to examine the suitability of an aerodynamic wing design, allowing for the use of a combined HLFC-VC concept for transonic transport aircraft. The paper describes the phenomenon of laminar flow and outlines the wing design process. It then discusses the benefits and penalties of the variable – camber wing concept. Description is then given of the aerodynamic design of a wing which incorporated both laminar flow and variable camber technologies. It concludes with a discussion of the results and recommendations for future work. * Lecturer, Aerospace Engineering, Universiti Putra Malaysia, Serdang, Selangor DE., 43400, MALAYSIA; p_edi@eng.upm.edu.my. † Professor of Aircraft Design, Head, Aerospace Engineering Group, Department of Power, Propulsion and Aerospace Engineering, School of Engineering, Cranfield University, Cranfield, Bed‟s MK43 0AL, UK; j.p.fielding@cranfield.ac.uk., Senior Member of AIAA.
