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 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.

This is an ideal book for graduate students and researchers interested in the aerodynamics, structural dynamics and flight dynamics of small birds, bats and insects, as well as of micro air vehicles (MAVs), which present some of the richest problems intersecting science and engineering. The agility and spectacular flight performance of natural flyers, thanks to their flexible, deformable wing structures, as well as to outstanding wing, tail and body coordination, is particularly significant. To design and build MAVs with performance comparable to natural flyers, it is essential that natural flyers' combined flexible structural dynamics and aerodynamics are adequately understood. The primary focus of this book is to address the recent developments in flapping wing aerodynamics. This book extends the work presented in Aerodynamics of Low Reynolds Number Flyers (Shyy et al. 2008).

Flapping-wing propulsion was studied experimentally through Laser Doppler Velocimetry. Measurements were both time-averaged and unsteady, and were conducted on a Micro- Air Vehicle (MAV) model developed at NPS by Professors Max Platzer and Kevin Jones. The objective of this work was to further understanding of the aerodynamics of flapping-wing propulsion. In specific, this study examined separation control on the leading fixed wing due to entrainment by the trailing flapping wings. Further, a study of wake topology examined differences between the optimal and off-optimal cases. Experimental studies took place in the NPS 5' x 5' low speed wind tunnel. The model was supported on a test stand and LDV measurements of the flow field were taken. Studies were made at varying freestream velocities, angles of attack, and flapping frequencies. The test stand was instrumented with force balances to show forces in both the streamwise and vertical directions.

Flapping wing vehicles (FWVs) have unique flight characteristics and the successful flight of such a vehicle depends upon efficient design of the flapping mechanisms while keeping the minimum weight of the structure. Flapping Wing Vehicles: Numerical and Experimental Approach discusses design and kinematic analysis of various flapping wing mechanisms, measurement of flap angle/flapping frequency, and computational fluid dynamic analysis of motion characteristics including manufacturing techniques. The book also includes wind tunnel experiments, high-speed photographic analysis of aerodynamic performance, soap film visualization of 3D down washing, studies on the effect of wing rotation, figure-of-eight motion characteristics, and more. Features Covers all aspects of FWVs needed to design one and understand how and why it flies Explains related engineering practices including flapping mechanism design, kinematic analysis, materials, manufacturing, and aerodynamic performance measures using wind tunnel experiments Includes CFD analysis of 3D wing profile, formation flight of FWVs, and soap film visualization of flapping wings Discusses dynamics and image-based control of a group of ornithopters Explores indigenous PCB design for achieving altitude and attitude control This book is aimed at researchers and graduate students in mechatronics, materials, aerodynamics, robotics, biomimetics, vehicle design and MAV/UAV.
