Research ArticleOpen accessEvery word in the titleOn Wing Tip Flow Around a Low Aspect Ratio Wing at Low Flight Speeds Using OpenFOAM® and Parallel ProcessingNikolaos Konstantinos Lampropoulos, Ioannis Eleftherios SarrisIn the present study, the effect of the wing tip geometry on the aerodynamic performance of a swept-back wing at moderate Reynolds numbers is investigated through numerical simulation and parallel processing. The aim is the identification of streamlines around the wing and subsequently the formation of the wing tip vortex. Due to the purely three-dimensional character of the flow, the … …Journal of Aircraft and Spacecraft Technology, Vol. 9, Issue 1 · 31 Jan 2025 · 9,549 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleLow Reynolds Number Wing Design for Unmanned Aerial Vehicle: A Case StudyMohammed El-Adawy, Alhassan H. Farid, Mohamed Ahmed Hassan et al.With the widespread utilization of Unmanned Aerial Vehicles (UAVs) in many fields, it is essential to identify the parameters governing their design process. By taking the wing as a showcase, this study intends to guide through the design process of the wing, elaborate on some important definitions, and show how different parts of an aircraft affect each other. The current … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 4 · 6 Dec 2022 · 7,367 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNumerical Analysis of Lattice Structures for Skin Layer in Camber Morphing WingBashir Alsaidi, Woong Yeol Joe, Muhammad AkbarUnlike conventional fixed wings and their static skin structure considering only expected aerodynamic loadings while filight, design strategies of skin structure for morphing wings require careful consideration of structural loading from shape changes and aerodynamics and their coupled effects in flight. Many morphing wings often overlook skin material and structure for the wing design. In addition to that, many works … …American Journal of Applied Sciences, Vol. 16, Issue 6 · 15 Jul 2019 · 7,742 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleNew Researches Examines the Wing Shapes to Reduce Vortex and WakeNicolae Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuIt is common to see clouds in the form of the sky, known as contrails, which are behind the engines of a reaction plan. What is not always visible is a wind whirl that comes out of the top of each wing - like two small horizontal tornadoes - leaving behind a turbulent awakening behind the vehicle. Awakening is a … …Journal of Aircraft and Spacecraft Technology, Vol. 2, Issue 1 · 19 Jun 2018 · 7,422 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleConceptual Design, Analysis and Construction of a Fixed-Wing Unmanned Arial Vehicle for Oil and Gas Pipeline SurveillanceAliyu Bhar Kisabo, Charles Attah Osheku, Sholiyi Olusegun SamuelOil and Gas Pipelines consists of pipes, compressors and pumps. These are frequently located in environments that are difficult to monitor and secure (e.g., creeks and remote areas). Attacks or damage to such installations can lead to enormous ecological impact and loss of revenue. Developing and implementing monitoring systems that can continuously assess the state and condition of oil and … …Journal of Aircraft and Spacecraft Technology, Vol. 1, Issue 1 · 1 Jun 2017 · 10,538 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRnai Induced Wing Modification in Leon Mutant Drosophila: A Developmental AnalysisSandeep Satapathy, Cheng Ting ChienThe precision of growth of an animal is meticulously regulated by extrinsic and intrinsic factors, with focus on maintenance of organismal homeostasis. The clue to change in physiology or metabolism of an organism, at times can be derived from the changes in phenotypes. In the Drosophila melanogaster model system, GAL 4-overexpressed RNAi driver males (Mini-White Marker), targeted against specific genes, … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 4 · 20 Dec 2013 · 6,719 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNumerical Investigation on Performance Improvement in Tube Inserted with Delta Winglets on Discrete Right-Angled Triangular PlatesAmnart Boonloi, Withada JedsadaratanachaiNumerical investigations on flow topology and heat transfer behavior in a round tube heat exchanger inserted with Delta Winglets (DW) on Discrete Right-angled Triangular Plates (DRTP) are performed. The influences of DW heights; b/D or BR = 0.05-0.25 and flow directions; DW with V-Downstream (DWVD) and DW with V-Upstream (DWVU), are studied for turbulent flow; Re = 3000-10,000. The finite … …Journal of Mathematics and Statistics, Vol. 13, Issue 1 · 16 Mar 2017 · 7,054 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMorphological Characteristics and Pathogenicity of Synchytrium psophocarpi (Rac.) Baumann Associated With False Rust on Winged BeanAbdollah Karami, Zainal Abidin Mior Ahmad, Kamaruzaman SijamProblem statement: Winged bean (Psophocarpus tetragonolobus L.) is an important tropical legume in countries like Malaysia due to its potential as a high protein value crop. However, bright-orange pustules observed on the veins of young leaves, stems, pods and sepals depict symptoms of false rust disease on beans. The causal agent of this disease has been found to be Synchytrium … …American Journal of Applied Sciences, Vol. 6, Issue 11 · 30 Nov 2009 · 9,581 accessesView PDFCite
