International Journal of Aerodynamics (IJAD)

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 Articles will not be published until the final proofs are validated by their authors.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.

  • Aerodynamic performance improvement of wings using supercritical airfoils and various winglets   Order a copy of this article
    by Mosfequr Rahman, Evan Cathers, John Crowe, Valentin Soloiu, Marcel Ilie, Hossain Ahmed 
    Abstract: This study serves to investigate the performances of several innovative and established wing-tip devices upon wings composed of supercritical airfoils. Comparisons of the effects of these wing-tip devices are made between wings composed of traditionally cambered airfoils. Winglets selected for analysis include blended, raked tip, split scimitar, fence tip, spiroid, and tip-sails. Respective lift and drag forces, coefficients (CL and CD), the CL/CD ratio, and vorticity generation were the results examined to evaluate aerodynamic performance. Results were obtained through simulations performed in ANSYS Fluent, and the trends were substantiated by subsonic wind tunnel testing. It was identified that there exists a distinct difference between performances of similar winglets on dissimilar airfoils. The wing utilising supercritical airfoils benefitted most from spiroid and tip sail winglets, combinations which provided approximate efficiency improvements of up to 21% and 18% respectively at cruise attitude.
    Keywords: supercritical airfoils; traditionally cambered airfoils; winglets; aerodynamic performance; k-epsilon model.

  • Effect of different cant angle blended winglet addition to different aircraft wing designs   Order a copy of this article
    by Mosfequr Rahman, John Crowe, Eric Pernell, Valentin Soloiu, Marcel Ilie, Hossain Ahmed 
    Abstract: The goal of this research is to determine the effect of adding winglets with different cant angles to three types of aircraft wings at various angles of attack. Blended winglets with cant angles of 30, 60 and 90 were considered for this study. Three different wings: rectangular shape, tapered shape and swept shape were modelled and simulated. Results from two data acquisition systems were compared to the corresponding results from Computational Fluid Dynamic (CFD) simulations. The addition of winglets to each wing had a positive effect on the lift coefficient while reducing drag. The Cessna 172 aircraft wing model experienced peak results with the 60 winglet. The Piper PA-46 aircraft wing model demonstrated maximum performance with winglet at a 30 cant angle, while the Boeing 737-300 aircraft wing model achieved the best performance with a winglet at a 90 cant angle.
    Keywords: blended winglets; cant angle; wind tunnel; k-ω SST model; lift coefficient; drag coefficient.
