Book Description
This book introduces a stability and control methodology named AeroMech, capable of sizing the primary control effectors of fixed wing subsonic to hypersonic designs of conventional and unconventional configuration layout. Control power demands are harmonized with static-, dynamic-, and maneuver stability requirements, while taking the six-degree-of-freedom trim state into account. The stability and control analysis solves the static- and dynamic equations of motion combined with non-linear vortex lattice aerodynamics for analysis. The true complexity of addressing subsonic to hypersonic vehicle stability and control during the conceptual design phase is hidden in the objective to develop a generic (vehicle configuration independent) methodology concept. The inclusion of geometrically asymmetric aircraft layouts, in addition to the reasonably well-known symmetric aircraft types, contributes significantly to the overall technical complexity and level of abstraction. The first three chapters describe the preparatory work invested along with the research strategy devised, thereby placing strong emphasis on systematic and thorough knowledge utilization. The engineering-scientific method itself is derived throughout the second half of the book. This book offers a unique aerospace vehicle configuration independent (generic) methodology and mathematical algorithm. The approach satisfies the initial technical quest: How to develop a ‘configuration stability & control’ methodology module for an advanced multi-disciplinary aerospace vehicle design synthesis environment that permits consistent aerospace vehicle design evaluations?

Book Description
Flight Dynamics, Simulation, and Control of Aircraft: For Rigid and Flexible Aircraft explains the basics of non-linear aircraft dynamics and the principles of control-configured aircraft design, as applied to rigid and flexible aircraft, drones, and unmanned aerial vehicles (UAVs). Addressing the details of dynamic modeling, simulation, and control in a selection of aircraft, the book explores key concepts associated with control-configured elastic aircraft. It also covers the conventional dynamics of rigid aircraft and examines the use of linear and non-linear model-based techniques and their applications to flight control. This second edition features a new chapter on the dynamics and control principles of drones and UAVs, aiding in the design of newer aircraft with a combination of propulsive and aerodynamic control surfaces. In addition, the book includes new sections, approximately 20 problems per chapter, examples, simulator exercises, and case studies to enhance and reinforce student understanding. The book is intended for senior undergraduate and graduate mechanical and aerospace engineering students taking Flight Dynamics and Flight Control courses. Instructors will be able to utilize an updated Solutions Manual and figure slides for their course.

Book Description
This book presents a detailed look at high-lift aerodynamics, which deals with the aerodynamic behavior of lift augmentation means from various approaches. After an introductory chapter, the book discusses the physical limits of lift generation, giving the lift generation potential. It then explains what is needed for an aircraft to fly safely by analyzing the high-lift-related requirements for certifying an aircraft. Aircraft needs are also analyzed to improve performance during takeoff, approach, and landing. The book discusses in detail the applied means to increase the lift coefficient by either passive and active high-lift systems. It includes slotless and slotted high-lift flaps, active and passive vortex generating devices, boundary and circulation control, and powered lift. Describing methods that are used to evaluate and design high-lift systems in an aerodynamic sense, the book briefly covers numerical as well as experimental simulation methods. It also includes a chapter on the aerodynamic design of high-lift systems. FEATURES Provides an understanding of the physics of flight during takeoff and landing from aerodynamics to flight performance and from simulation to design Discusses the physical limits of lift generation, giving the lift generation potential Concentrates on the specifics of high-lift aerodynamics to provide a first insight Analyzes aircraft needs to improve performance during takeoff, approach, and landing Focuses on civil transport aircraft applications but also includes the associated physics that apply to all aircraft This book is intended for graduate students in aerospace programs studying advanced aerodynamics and aircraft design. It also serves as a professional reference for practicing aerospace and mechanical engineers who are working on aircraft design issues related to takeoff and landing.

Book Description
The largest weapons development effort ever undertaken by the State of Israel, the Lavi fighter program envisioned a new generation of high-performance aircraft. Controversially, Israel Aircraft Industries intended to develop and manufacture the fighters in Israel with U.S. financial support. The sophisticated planes, developed in the mid-1980s, were unique in design and intended to make up the majority of the Israeli Air Force. Though a great deal of prestige and money was staked, developmental costs increased and doubts arose as to whether the Lavi could be the warplane it was meant to be. Eventually, the program became a microcosm for the US-Israel relationship and of Israeli society itself--a study in the ambitions, fears, and internal divisions that shaped them. The fighter never made it to operational service. Despite the passage of time since its cancelation, the Lavi remains a controversial subject within Israeli society to this day. Until now, the full breadth and significance of the Lavi story has never been told. "Lavi: Israel's Lost Winged Lion" traces the evolution of the Lavi fighter from its genesis in the 1970s to its demise in August of 1987. Painting the era's political landscape on both sides of the ocean, author John Golan examines the roles of such Israeli military icons and political leaders as Ezer Weizman, Ariel Sharon, Menachem Begin, and Yitzhak Rabin. On the American side, Golan traces the evolution of U.S. government policy towards the program, detailing a complex, nuanced picture of the U.S. foreign policy apparatus and of U.S.-Israel relations in general--from President Reagan's public endorsement of the program on the White House lawn to Defense Secretary Caspar Weinberger's unremitting attempts to cancel the program in succeeding years.
