W IND disturbances are a common factor in aviation accidents. Among 126 airplane accidents that occurred between 1979 and 2009 involving loss of control in flight, 14% listed windshear, turbulence, or thunderstorms as a cause or contributing factor. Moreover, 86% of the accidents initiated by atmospheric disturbances led to an upset flight condition, which usually entails an excursion of the ai...

Timely identifying flight diversions is a crucial aspect of efficient multi-modal transportation. When an airplane diverts, logistics providers must promptly adapt their transportation plans in order to ensure proper delivery despite such an unexpected event. In practice, the different parties in a logistics chain do not exchange real-time information related to flights. This calls for a means ...

The accelerated growth in aircraft industries desire effectual schemes, programs, innovative designs of advanced systems and facilities to accomplish the augmenting need for home-free air transportation. In this paper, a contemporary conceptual design of a cambered airfoil has been proposed in order to providing augmented effective lift force relative to the airplane, and to eliminating drawbac...

Aerodynamic design optimization of an airfoil for the Mars exploration airplane has been demonstrated by using an evolutionary algorithm. The adaptive range genetic algorithm is used for efficient and robust design optimization. Two-dimensional Navier-Stokes solver is used for accurate aerodynamic performance evaluation. The present computation is parallelized on the SX-6 vector computers in In...

This paper describes a general sensor model for the georeferencing of imagery from CCD linear array sensors with along-track stereo viewing, carried on airplane or satellite. The model combines the standard photogrammetric triangulation with a sensor external orientation modeling. The sensor attitude and position, which are different for each image-line, are modeled with time-dependent piecewis...

In this paper a combination of Fuzzy Logic Control (FLC) and Model 1 Reference Adaptive Control (MRAC) will be developed to stabilize and control a 2 fixed-wing unmanned aerial vehicle (UAV). The control must be able to direct the 3 airplane towards different waypoints while at the same time maintaining the UAV 4 stable. Also, the control should be transferable to similar UAV models with little...

A model of human visual detection performance has been developed, based on available anatomical and physiological data for the primate visual system. The inhomogeneous retino-cortical (IRC) model computes detection thresholds by comparing simulated neural responses to target patterns with responses to a uniform background of the same luminance. The model incorporates human ganglion cell samplin...

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 c...
