Book Description
Aircraft hardware-in-the-loop simulation is an invaluable tool to flight test engineers: it reveals design and imple,mentation flaws while operating in a controlled environment. Engineers, however, must always be skeptical of the results and analyze them within their proper context. Engineers must carefully ascertain whether an anomaly that occurs in the simulation will also occur in flight. This report presents a chronology illustrating how misleading simulation timing problems led to the implementation of an overly complex position data synchronization guidance algorithm in place of a simpler one. The report illustrates problems caused by the complex algorithm and how the simpler algorithm was chosen in the ned. Brief descriptions of the project objectives, approach, and simulation are presented. The misleading simulation results and the conclusions then drawn are presented.

Book Description
The first flight test phase of the NASA Dryden Flight Research Center Autonomous Formation Flight project has successfully demonstrated precision autonomous station-keeping of an F/A-18 research airplane with a second F/A-18 airplane. Blended inertial navigation system (INS) and global positioning system (GPS) measurements have been communicated across an air-to-air telemetry link and used to compute relative-position estimates. A precision research formation autopilot onboard the trailing airplane controls lateral and vertical spacing while the leading airplane operates under production autopilot control. Four research autopilot gain sets have been designed and flight-tested, and each exceeds the project design requirement of steady-state tracking accuracy within 1 standard deviation of 10 ft.

Formation Control of Multiple Autonomous Vehicle Systems

Formation Control of Multiple Autonomous Vehicle Systems PDF Author: Hugh H. T. Liu
Publisher: John Wiley & Sons
ISBN: 1119263042
Category : Science
Languages : en
Pages : 272

Book Description
This text explores formation control of vehicle systems and introduces three representative systems: space systems, aerial systems and robotic systems Formation Control of Multiple Autonomous Vehicle Systems offers a review of the core concepts of dynamics and control and examines the dynamics and control aspects of formation control in order to study a wide spectrum of dynamic vehicle systems such as spacecraft, unmanned aerial vehicles and robots. The text puts the focus on formation control that enables and stabilizes formation configuration, as well as formation reconfiguration of these vehicle systems. The authors develop a uniform paradigm of describing vehicle systems’ dynamic behaviour that addresses both individual vehicle’s motion and overall group’s movement, as well as interactions between vehicles. The authors explain how the design of proper control techniques regulate the formation motion of these vehicles and the development of a system level decision-making strategy that increases the level of autonomy for the entire group of vehicles to carry out their missions. The text is filled with illustrative case studies in the domains of space, aerial and robotics. • Contains uniform coverage of "formation" dynamic systems development • Presents representative case studies in selected applications in the space, aerial and robotic systems domains • Introduces an experimental platform of using laboratory three-degree-of-freedom helicopters with step-by-step instructions as an example • Provides open source example models and simulation codes • Includes notes and further readings that offer details on relevant research topics, recent progress and further developments in the field Written for researchers and academics in robotics and unmanned systems looking at motion synchronization and formation problems, Formation Control of Multiple Autonomous Vehicle Systems is a vital resource that explores the motion synchronization and formation control of vehicle systems as represented by three representative systems: space systems, aerial systems and robotic systems.

Book Description
One of the great aircraft of the Cold War era, the McDonnell Douglas F-4 Phantom II was the most heavily produced supersonic, all-weather fighter bomber. Capable of a top speed of Mach 2.23, it set sixteen world records including an absolute speed record of 1,606 mph and an altitude record of 98,557 feet. The F-4 flew Vietnam, in the Arab-Israeli conflict, and the Gulf War and amassed a record of 393 aerial victories. F-4s also flew as part of the USAF Thunderbirds and the U.S. Navy Blue Angels flight demonstration teams. Originally printed by McDonnell and the U.S. Navy in the 1960s, this flight operating handbook taught pilots everything they needed to know before entering the cockpit. Classified "restricted", the manual was recently declassified and is here reprinted in book form. This affordable facsimile has been reformatted. Care has been taken however to preserve the integrity of the text.
