Download or read book Design and Development of a Micro Air Vehicle (MAV) written by SeWoong Jung and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: This thesis presents the design, fabrication, capabilities, and analysis of a test-bed Micro Air Vehicle (MAV) used in developing a vision-based flight control algorithm. Vision-based controlled flight and its further developments are geared towards use on MAVs of the future. A test-bed airplane was designed from MAV concepts, and was large enough to accommodate the current commercial components available on the market. Two generations of the vision-based MAV were developed and tested. Each generation had 0.6 m wingspan and used a pusher configuration with a flexible wing concept. The second generation, however, had an improved fuselage and wing design, drive system, and a unique morphing mechanism. Both vehicles were tested and compared during numerous flight and wind tunnel tests. Effects of the morphing mechanism on the flexible wing were analyzed in the wind tunnel using the digital image correlation method.
Book Synopsis Introduction to the Design of Fixed-wing Micro Air Vehicles by : T. J. Mueller

This book was released on 2007-01 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: This intriguing book breaks new ground on an emerging subject that has attracted considerable attention: the use of unmanned micro air vehicles (MAVs) to conduct special, limited duration missions. Significant advances in the miniaturization of electronics make it now possible to use vehicles of this type in a detection or surveillance role to carry visual, acoustic, chemical, or biological sensors. Interestingly, many of the advances in MAV technology can be traced directly to annual student competitions, begun in the late 1990s, that use relatively low cost model airplane equipment. The wide variety of configurations entered in these contests and their ongoing success has led to a serious interest in testing the performance of these vehicles for adaptation to practical applications. MAVs present aerodynamic issues unique to their size and the speeds at which they operate. Of particular concern is the aerodynamic efficiency of various fixed wing concepts. Very little information on the performance of low aspect ratio wing planforms existed for this flight regime until MAVs became of interest and the proliferation of fixed wing designs has since expanded. This book presents a brief history of unmanned air vehicles and offers elements of aerodynamics for low aspect ratio wings. Propulsion and the basic concepts for fixed wing MAV design are presented, as is a method for autopilot integration. Three different wing configurations are presented in a series of step-by-step case studies. The goal of the book is to assist both working professionals and students to design, build, and fly MAVs, and do so in a way that will advance the state of the art and lead to the development of even smalleraircraft.

This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Micro air vehicles (MAVs) are a special subset of unmanned air vehicles (UAVs) that warrant a significant level of scientific interest. In general, MAVs are small, inexpensive and often expendable platforms, flown by remote pilot, or autopilot. Because they are often flown by inexperienced pilots or autonomous control, they need to have very reliable and benign flight characteristics govern the design. The University of Florida has developed a series of MAVs that adopt a flexible-wing concept, most notably featuring a carbon fiber structure and a thin extensible membrane skin. Because their design requirements mandate that they perform reliably in flight, careful thought and consideration must go into a MAV design. Some of the design may come from intuition and experience, but it must ultimately be verified through quantitative testing. In addition, the design process must be performed in a way that is accurate and repeatable. The purpose of this research was to develop an efficient and accurate methodology for designing, producing and reproducing MAVs. This approach evolved into a rapid prototyping process of designing and manufacturing MAVs while still maintaining geometric accuracy and aerodynamic integrity. The solution was the development of a software-based design tool, called MAVLAB, which incorporated specialized CAD design features, aerodynamic analysis tools and rapid manufacturing through automated machining. This thesis includes an overview of the University of Florida s design procedure, an example case study and a users' manual for MAVLAB.
Download or read book The DelFly written by G.C.H.E. de Croon and published by Springer. This book was released on 2015-11-26 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces the topics most relevant to autonomously flying flapping wing robots: flapping-wing design, aerodynamics, and artificial intelligence. Readers can explore these topics in the context of the "Delfly", a flapping wing robot designed at Delft University in The Netherlands. How are tiny fruit flies able to lift their weight, avoid obstacles and predators, and find food or shelter? The first step in emulating this is the creation of a micro flapping wing robot that flies by itself. The challenges are considerable: the design and aerodynamics of flapping wings are still active areas of scientific research, whilst artificial intelligence is subject to extreme limitations deriving from the few sensors and minimal processing onboard. This book conveys the essential insights that lie behind success such as the DelFly Micro and the DelFly Explorer. The DelFly Micro, with its 3.07 grams and 10 cm wing span, is still the smallest flapping wing MAV in the world carrying a camera, whilst the DelFly Explorer is the world's first flapping wing MAV that is able to fly completely autonomously in unknown environments. The DelFly project started in 2005 and ever since has served as inspiration, not only to many scientific flapping wing studies, but also the design of flapping wing toys. The combination of introductions to relevant fields, practical insights and scientific experiments from the DelFly project make this book a must-read for all flapping wing enthusiasts, be they students, researchers, or engineers.
Book Synopsis Development of a Tandem-wing Flapping Micro Aerial Vehicle Prototype and Experimental Mechanism by : Christopher DiLeo
Download or read book Development of a Tandem-wing Flapping Micro Aerial Vehicle Prototype and Experimental Mechanism written by Christopher DiLeo and published by ProQuest. This book was released on 2007 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the field of micro-aerial vehicles (MAVs), simplicity of design is an important design characteristic. Simplicity in this context implies light weight, a prerequisite for flapping flight, and from a practical standpoint it aids in the manufacture and operation of the mechanism on such a small scale. However, simplicity comes at a price: as mechanisms are simplified they have fewer degrees of freedom, lower controllability, less power output. All of these will effect the ability of the mechanism to generate lift, but the losses can be minimized through proper design and implementation. This thesis describes the design and fabrication of a flapping-wing MAV deriving inspiration from the biological mechanisms of a dragonfly. Dragonflies flap with an inclined stroke plane for hovering flight, which in conjunction with their two pairs of wings, presents an unexplored area of research for MAVs. Small changes in the hovering-flight wing kinematics create large simplifications in their mechanical reproduction. The MAV utilizes these simplifications while maintaining the most important characteristics of dragonfly hovering flight, including passive rotation of the wings, reliance on drag forces to generate lift, and the fluid interactions between adjacent wings flapping out-of-phase. Two successive prototypes are presented, focusing on component design and fabrication techniques. These prototypes allow for easy modification of kinematic variables (phase shift between the fore-and hind-wings and factors that affect wing angle-of-attack) and component variables (most importantly, wing characteristics: size, shape, flexibility), important for future optimization. Initial experimental validation of the prototypes is presented. To facilitate the experimental validation, a mechanical flapping wing mechanism has been designed and fabricated which is able to reproduce the high-stroke-plane kinematics utilized by dragonflies, an ability lacking in present flapping mechanisms. This flapping wing mechanism allows for the measurement of the instantaneous forces on a wing for a particular kinematics, by driving the wing with dynamically similar kinematics in a tank of oil. These experiments will be used in the future to analyze and optimize the lift generated by flapping-wing MAVs.

Download or read book Design and Prototype Development of a Wireless Power Transmission System for a Micro Air Vehicle (MAV) written by Robert L. Vitale and published by . This book was released on 1999-06-01 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microwave radiation at 1.0 GHz and 1.3 GHz is used to demonstrate remote powering of a micro air vehicle (MAV). Several prototype microwave rectifier systems were fabricated in microstrip using EEsof(registered) computer aided engineering (CAE) software to assist in their design. Radio frequency (RF) parameters of the rectifiers were measured on a vector network analyzer. RF-to- DC conversion efficiency was measured for several designs and with various circuit loads consisting of lumped elements and DC motors. A peak RF-to-DC conversion efficiency of 33 percent was achieved. MAV antenna designs were investigated by simulating 68 geometries using the GNEC(registered) numerical electromagetics computer program. Two prototype MAVs were assembled, each consisting of microwave rectifier, antenna and a miniature DC motor. It was demonstrated that a 1.8-Watt, 1.3-GHz microwave signal could power the DC motor at free space distance of 30 inches from transmitting antenna to prototype MAV. Greater operating distances are proposed by using higher transmitting power and antenna gain.
Book Synopsis Small Unmanned Aircraft by : Randal W. Beard
Download or read book Small Unmanned Aircraft written by Randal W. Beard and published by Princeton University Press. This book was released on 2012-02-26 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Autonomous unmanned air vehicles (UAVs) are critical to current and future military, civil, and commercial operations. Despite their importance, no previous textbook has accessibly introduced UAVs to students in the engineering, computer, and science disciplines--until now. Small Unmanned Aircraft provides a concise but comprehensive description of the key concepts and technologies underlying the dynamics, control, and guidance of fixed-wing unmanned aircraft, and enables all students with an introductory-level background in controls or robotics to enter this exciting and important area. The authors explore the essential underlying physics and sensors of UAV problems, including low-level autopilot for stability and higher-level autopilot functions of path planning. The textbook leads the student from rigid-body dynamics through aerodynamics, stability augmentation, and state estimation using onboard sensors, to maneuvering through obstacles. To facilitate understanding, the authors have replaced traditional homework assignments with a simulation project using the MATLAB/Simulink environment. Students begin by modeling rigid-body dynamics, then add aerodynamics and sensor models. They develop low-level autopilot code, extended Kalman filters for state estimation, path-following routines, and high-level path-planning algorithms. The final chapter of the book focuses on UAV guidance using machine vision. Designed for advanced undergraduate or graduate students in engineering or the sciences, this book offers a bridge to the aerodynamics and control of UAV flight.
Book Synopsis Style Guide for Micro Aerial Vehicle Operator Machine Interface Design by : Ming Hou
Download or read book Style Guide for Micro Aerial Vehicle Operator Machine Interface Design written by Ming Hou and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Little research has been conducted to study desirable handheld interface design approaches for the control of Micro Aerial Vehicles (MAVs). To address this issue, Defence Research and Development Canada (DRDC) - Toronto performed a focus group study, literature reviews, a spiral development of three Operator Machine Interface (OMI) prototypes, and an empirical experiment that tested various display modes and command control input methods for MAV control. The results of these OMI design research efforts are summarized in this style guide, which provides a generic framework for handheld OMI development. Detailed design solutions will be developed using, in part, the criteria provided in this document. The MAV style guide: 1) Identifies assumptions regarding MAV use that may affect design decisions; 2) Defines the essential components of a handheld MAV OMI; 3) Outlines style guidelines common to OMI control elements; 4) Outlines style guidelines common to OMI displays; and 5) Identifies ideal interaction response times for OMI functions. It is assumed that the major components of an OMI will include manual controls and a touch screen with a diagonal dimension of approximately nine inches. However, as new technologies and displays are developed these guidelines may change due to the evolving design and functionality requirements of MAV systems.

Available in PDF, EPUB and Kindle. Book excerpt: Unmanned Aircraft Systems delivers a much needed introduction to UAV System technology, taking an integrated approach that avoids compartmentalising the subject. Arranged in four sections, parts 1-3 examine the way in which various engineering disciplines affect the design, development and deployment of UAS. The fourth section assesses the future challenges and opportunities of UAS. Technological innovation and increasingly diverse applications are two key drivers of the rapid expansion of UAS technology. The global defence budget for UAS procurement is expanding, and in the future the market for civilian UAVs is expected to outmatch that of the military. Agriculture, meteorology, conservation and border control are just a few of the diverse areas in which UAVs are making a significant impact; the author addresses all of these applications, looking at the roles and technology behind both fixed wing and rotorcraft UAVs. Leading aeronautical consultant Reg Austin co-founded the Bristol International Remotely Piloted Vehicle (RPV) conferences in 1979, which are now the longest-established UAS conferences worldwide. In addition, Austin has over 40 years' experience in the design and development of UAS. One of Austin's programmes, the "Sprite UAV System" has been deployed around the world and operated by day and night, in all weathers.

Download or read book Model Update of a Micro Air Vehicle (Mav) Flexible Wing Frame with Uncertainty Quantification written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-06-21 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper describes a procedure to update parameters in the finite element model of a Micro Air Vehicle (MAV) to improve displacement predictions under aerodynamics loads. Because of fabrication, materials, and geometric uncertainties, a statistical approach combined with Multidisciplinary Design Optimization (MDO) is used to modify key model parameters. Static test data collected using photogrammetry are used to correlate with model predictions. Results show significant improvements in model predictions after parameters are updated; however, computed probabilities values indicate low confidence in updated values and/or model structure errors. Lessons learned in the areas of wing design, test procedures, modeling approaches with geometric nonlinearities, and uncertainties quantification are all documented.
