The problem of attitude stabilization of a fighter aircraft is investigated in this paper. The practical aspects of a real physical system like existence of external disturbance with unknown upper bound and actuator saturation are considered in the process of controller design of this aircraft. In order to design a robust autopilot in the presence of the actuator saturation, the Composite Nonli...

Measurement of aircraft attitude is a necessary step for the autonomous control of the aircraft. Autonomous aircraft are useful for a range of military and civilian purposes. A method of very low computational complexity is presented that allows the pitch and roll angles of an aircraft to be measured onboard an unmanned aircraft from real-time video of the horizon. This method can be used for m...

Previous research on civil aircraft inspection and maintenance has shown the important role teamwork plays in completing aircraft inspection/maintenance tasks. Hence, it is necessary to develop team training tools for aircraft maintenance technicians (AMT) to enhance team skills and team performance within the aircraft inspection/maintenance environment. In response to this need, this paper des...

This paper describes updated results from a partnership between the Sikorsky Aircraft Corporation and the Georgia Institute of Technology to develop, improve, and flight test a sensor, guidance, navigation, control, and real-time flight path optimization system to support high performance Nap-of-the-Earth (NOE) helicopter flight. The emphasis here is on optimization for a combination of low hei...

Multiple classifier systems (MCS) are considered as one of the most significant advances in pattern classification in recent years. Numerous studies (both theoretical and empirical) have proved that MCS are effective in achieving improved classification performance for various application problems. Aircraft engine fault diagnosis plays a crucial rule in costeffective operation of aircraft engin...

Recent advances in navigation and data communication technologies make it feasible for individual aircraft to plan and fly their trajectories in the presence of other aircraft in the airspace. This way, individual aircraft can take advantage of the atmospheric and traffic conditions to optimally plan their paths. This capability is termed as the free flight concept. While the free flight concep...

Air Traac Management Systems (ATMS) of the future allow for the possibility of Free Flight, in which aircraft choose their own optimal routes, altitude and speed. In a free ight environment, the trajectories of diierent aircraft may be connicting, in which case aircraft may or may not cooperate in resolving the connict. In this paper, noncooperative connict resolution methods based on game theo...

At airports with closely-spaced parallel runways, the inability to conduct simultaneous approaches in all weather conditions is a cause of significant delay. One concept for reducing delay is paired approaches, where two airc raft on closely spaced approaches are ‘paired’, and the ‘trail’ aircraft stays within a safe zone relative to the ‘lead’. This positioning guarantees that neither aircraft...

Planetary exploration may be enhanced by the use of aircraft for mobility. This paper reviews the development of aircraft for planetary exploration missions at NASA and reviews the power and propulsion options for planetary aircraft. Several advanced concepts for aircraft exploration, including the use of in situ resources, the possibility of a flexible all-solid-state aircraft, the use of ento...

Due to the large increase in the density of aircraft arrivals at airports in recent years, it has become important to optimize the scheduling of aircraft landings in order to reduce wait time, improve airport efficiency, and minimize fuel consumption while maintaining safety. As the density of aircraft arrivals increases, however, so too does the complexity of trajectory planning and generation...
