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 Articles will not be published until the final proofs are validated by their authors.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

Online First articles are published online here, before they appear in a journal issue. Online First articles are fully citeable, complete with a DOI. They can be cited, read, and downloaded. Online First articles are published as Open Access (OA) articles to make the latest research available as early as possible.

Open AccessArticles marked with this Open Access icon are Online First articles. They are freely available and openly accessible to all without any restriction except the ones stated in their respective CC licenses.

  • Performance improvement of the Fixed Wing UAV through wing span optimisation   Order a copy of this article
    by Paul P. Okonkwo, Paul O. Jemitola 
    Abstract: This article describes the wing optimisation of an already designed and manufactured fixed wing UAV. The objective of the study was to improve the aircraft aerodynamic efficiency and flight performance with minimal disruption to the aircraft geometry. Accordingly, the study performed the optimisation by varying just the span within an acceptable limit and then determining the aerodynamic characteristics of the resulting geometry. The results obtained from the ensuing activities showed that the model with a span of 5.8m produced the best aerodynamic performance of 6% increase in lift coefficient and a 16% increase in L/D compared to the baseline aircraft. Nevertheless, since this study did not consider structural, aero-elastic and stability effects in this optimisation, there is the need for a multidisciplinary optimisation to ascertain the weight penalty and stability variations of increased span on the overall performance of the concept.
