Forthcoming articles have been peer-reviewed and accepted for publication but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

Forthcoming articles must be purchased for the purposes of research, teaching and private study only. These articles can be cited using the expression "in press". For example: Smith, J. (in press). Article Title. Journal Title.

  • Experimental assessment of a double-element Clark-Y airfoil as a flap for its lift capabilities at high Reynolds numbers   Order a copy of this article

    Abstract: Introduction of secondary wing elements allows the overall aircraft system to attain higher lift coefficients even at lower cruise speeds. Introduction of such secondary wing elements allow the overall aircraft system to attain higher lift coefficients even at lower cruise speeds. Experiments involved under this paper observes and works around the lift behaviour of Clark-Y airfoil system through comprehensive understanding of localised pressure coefficients at a considerably higher Reynolds numbers up to 54,000 and presents a study summary of its lift coefficient for flap orientation up to an attack angle of 15 while the main element remains at 0 throughout the experiment. The study was conducted by accumulating static pressure data from multiple sensors of a pressure transducer at given Reynolds number inside a wind tunnel whose air velocities reached a maximum of 8 m/s. The results show signs of stall right after 10 flap AOA with lift coefficient (CL) dropping below 0 only after 12 of flap AOA. Among all prevalent orientations, flap AOA at 5 promised greatest pressure difference between the upper and lower surfaces and caused the lift coefficient (CL) to reach a maximum, i.e., 2.33.
    Keywords: Clark-Y; double-element; high reynolds number; lift capability.
