In this study, active fault tolerant flight control technique with actuation reconfiguration is proposed. For this purpose two-stage Kalman filter (TSKF) is designed to identify the control distribution matrix elements corresponding to the faulty actuator, and a control reconfiguration action is taken to keep the performance of the impaired aircraft same as that of the unimpaired aircraft. Thus...

The current Air Force aircraft logistics system is reactive in nature, meaning that once a fault is detected, maintenance personnel must perform fault isolation procedures and then take steps to repair or replace the faulty item. The Autonomic Logistics System (ALS) concept changes this reactive process into a proactive one. This new approach to the logistics process shows the potential for cos...

Abstract This paper develops and compares two fuzzy logic based and a traditional rule-based pattern recognition system, which perform target recognition with data from a typical range and doppler resolving radar. The parameters used by the pattern recognition systems are target altitude, velocity, range from nearest base, and radar cross section. The pattern recognition systems identify four c...

This paper presents a comparative analysis of two intelligent reference learning techniques to achieve better performance of pitch control of an aircraft. Fuzzy Model Reference Learning Controller (FMRLC) and Radial Basic Function Neural Controller (RBFNC) are designed for pitch control of a FOXTROT fighter aircraft. These controllers utilize a learning mechanism, which observes the plant outpu...

No fighter pilot ever flies a combat mission solo. \Ve always fly as a teamwith our wingmen, who provide mutual support and m<Lximizeour ability to accomplish our objectives. It's impossible to win solo because so much needs to get done in a rapidly changing environment, and the missions are extremely complex. In order to e:\l1loit the advantages of a unified team, we assign roles and responsib...

In this paper a classical feedback controller has been designed to furnish fast acting characteristics in the face of parametric perturbation using two parameters, Generalized Time Constant and Characteristic Ratios. The design is extended to develop a controller for the pitch control of a BRAVO fighter aircraft. This design allows reduction of overshoot, control of speed of the response and ro...

More than 100 of the worlds most potent fighter aircraft are depicted in superbly detailed cutaway drawings: from the canvas-and-string contraptions of World War I to the amazing stealth fighters that are taking air combat into the 21st century. Accompanied by fascinating technical and developmental descriptions, each drawing reveals and clearly identifies the aircrafts airframe structures, eng...

Years of training, practice and unique skills are required for a Fighter pilot to perform demanding challenging operations in technologically cutting-edge aircraft. To provide concise overview physical fitness, muscle cross-sectional area (CSA) GZexposure their interaction fighter pilots. A search PubMed, CINHAL, Google scholar database was conducted find relevant studies pertaining pilots, cer...
