Research ArticleOpen accessEvery word in the titleDesign and Analysis of a Helium-Assisted Hybrid Drone for Flight Time EnhancementGeronimo Macias, Kooktae LeeIn this study, a new design of a helium-assisted hybrid drone is proposed for flight time enhancement. As is widely known, most of the drones with a Vertical Take-Off and Landing (VTOL) feature have a short operation time, limiting their capability to carry out sustainable operations for the given missions. Thus, with the clear goal of enhancing flight time, this … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 4 · 23 Dec 2022 · 6,373 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFDIR Strategy for Sensor Faults During Re-entry FlightGianfranco Morani, Mariangela Di LorenzoIn this study, a Fault Detection, Isolation and Reconfiguration (FDIR) strategy is proposed for dealing with the problem of single sensor faults during a re-entry flight. The proposed algorithms rely on a model based Fault Detection and Isolation. After the generation of a residual through a Kalman filter observer, detection is obtained via the estimation of residual signal statistics while … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 7 Apr 2018 · 8,690 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Modern FlightRelly Victoria Petrescu, Florian Ion Tiberiu Petrescu, Antonio Apicella et al.A modern flight involves both a great flight quality and high safety throughout. You can’t speak of a quality of flight today unless it provides increased comfort to all passengers in full safety and relaxation. Regardless of the aircraft design type, a minimum level of comfort is required in the passenger cabin so that they feel safe, comfortable, quiet, plus … …Journal of Aircraft and Spacecraft Technology, Vol. 1, Issue 4 · 19 Oct 2017 · 8,318 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePREDICTION OF FIGHT OR FLIGHT RESPONSE USING ARTIFICIAL NEURAL NETWORKSAbhijit Suresh, Sai Swarna Latha, Pooja Nair, N. RadhikaThe modern society has posed several threats to the public. Public security is declining with increasing anti-social behaviour. Cases of rape and terrorist attacks have become increasingly common and there is a strong demand for a security system to control such modalities. Anti-social behaviour is a key issue of public concern. Public perceptions, however, have been improving recently. The vital … …American Journal of Applied Sciences, Vol. 11, Issue 6 · 3 Apr 2014 · 8,041 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMerging Autopilot/Flight Control and Navigation-Flight Management SystemsKhaleel QutbodinIn this abstract the following commercial aircraft 3 avionics systems will be merged together: (1) Autopilot Flight Director System (APFDS), (2) Flight Control System (FCS) and (3) Flight Management Systems (FMS). Problem statement: These systems perform functions that are dependant and related to each other, also they consists of similar hardware components. Each of these systems consists of at least … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 4 Nov 2010 · 8,520 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRobust Flight Control Design for a Turn Coordination System with Parameter UncertaintiesAri Legowo, Hiroshi OkuboThis paper presents a method of robust control system design for aircraft flight control systems with the existence of uncertainty parameters such as stability and control derivatives resulted by parameter identification process using real flight test data. A nonlinear model of aircraft turn coordination system is considered where the problem is to find the optimal controller by using the H∞ … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 7,498 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleAbout Supersonic Flight and Mach 3 FlyingRelly Victoria Virgil PetrescuAerospace-BAC Concorde was a supersonic passenger aircraft. It was the result of a government treaty between the French and British governments, combining the efforts of Aerospace and British Aircraft Corporation. With only 20 aircraft built in total, the cost of the development phase was a major economic failure. In addition, Air France and British Airways were subsidized by the government … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 3 · 28 Aug 2020 · 8,926 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Vision System Based on Time-of-Flight and RGB Cameras Applied to Robotic Tree Peony Fruit HarvestingJiaming Liu, Dong Zhao, Tianxing Li, Jian ZhaoTree peony is a deciduous shrub endemic to China and the Peony Seed Oil (PSO) is an important plant oil resource. However, at present, fruits harvesting of peony are mainly completed by manual work with low efficiency. In response to the need for a mechanized operation, a multi-sources vision system based on Time-Of-Flight (TOF) and RGB cameras was set up … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 3 · 19 Aug 2020 · 6,329 accessesView PDFCite
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 · 9,538 accessesView PDFCite
Research ArticleOpen accessIn the keywordsData Clustering using Two-Stage Eagle Strategy Based on Slime Mould AlgorithmRachid Oucheikh, Achraf Touil, Mouhsene FriDataclustering is considered an important component of data mining which aims tosplit a given dataset into disjoint groups having the same similarities. Thedeveloped techniques for clustering have some challenges to cluster entities incomplex search space and most of them aim to maximize the sum of inter-clusterdistances and minimize the sum of intra-cluster distances. This objectivefunction is nonlinear and hard to … …Journal of Computer Science, Vol. 18, Issue 11 · 7 Nov 2022 · 5,791 accessesView PDFCite
