Close formation flight involving aerodynamic coupling through wingtip vortices shows significant promise to improve the efficiency of cooperative aircraft operations. Impediments to the application of this technology include internship communication required to establish precise relative positioning. This report proposes a method for estimating the lateral relative position between two aircraft in close formation flight through real-time estimates of the aerodynamic effects imparted by the leading airplane on the trailing airplane. A fuzzy algorithm is developed to map combinations of vortex-induced drag and roll effects to relative lateral spacing. The algorithm is refined using self-tuning techniques to provide lateral relative position estimates accurate to 14 in., well within the requirement to maintain significant levels of drag reduction. The fuzzy navigation algorithm is integrated with a leader-follower formation flight autopilot in a two-ship F/A-18 simulation with no intership communication modeled. It is shown that in the absence of measurements from the leading airplane the algorithm provides sufficient estimation of lateral formation spacing for the autopilot to maintain stable formation flight within the vortex. Formation autopilot trim commands are used to estimate vortex effects for the algorithm. The fuzzy algorithm is shown to operate satisfactorily with anticipated levels of input uncertainties.Hanson, Curtis E.Armstrong Flight Research CenterFORMATION FLYING; FUZZY SYSTEMS; WING TIP VORTICES; LATERAL CONTROL; F-18 AIRCRAFT; AUTONOMOUS NAVIGATION; AUTOMATIC PILOTS; ROLL; DRAG REDUCTION; FEEDBACK CONTROL; REAL TIME OPERATION; FLIGHT SIMULATION; ALGORITHMS

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.

Flight mechanics is the application of Newton's laws to the study of vehicle trajectories (performance), stability, and aerodynamic control. This volume details the derivation of analytical solutions of airplane flight mechanics problems associated with flight in a vertical plane. It covers trajectory analysis, stability, and control. In addition, the volume presents algorithms for calculating lift, drag, pitching moment, and stability derivatives. Throughout, a subsonic business jet is used as an example for the calculations presented in the book.

Introduction to Avionic Systems, Second Edition explains the principles and theory of modern avionic systems and how they are implemented with current technology for both civil and military aircraft. The systems are analysed mathematically, where appropriate, so that the design and performance can be understood. The book covers displays and man-machine interaction, aerodynamics and aircraft control, fly-by-wire flight control, inertial sensors and attitude derivation, navigation systems, air data and air data systems, autopilots and flight management systems, avionic systems integration and unmanned air vehicles. About the Author. Dick Collinson has had "hands-on" experience of most of the systems covered in this book and, as Manager of the Flight Automation Research Laboratory of GEC-Marconi Avionics Ltd. (now part of BAE Systems Ltd.), led the avionics research activities for the company at Rochester, Kent for many years. He was awarded the Silver Medal of the Royal Aeronautical Society in 1989 for his contribution to avionic systems research and development.
