In this paper, parametric and numerical model of the DC motor, connected to aircraft propellers are extracted. This model is required for controlling trust and velocity of the propellers, and consequently, an aircraft. As a result, both of torque and speed of the propeller can be controlled simultaneously which increases the kinematic and kinetic performance of the aircraft. Parametric model of...

Spatial disorientation (SD) has been a contributing factor in aviation mishaps for decades and efforts to mitigate SD have not been proportionate to the danger it poses to pilots. We argue that SD contributes to nearly 33% of all mishaps with a fatality rate of almost 100%. However, SD has not garnered the respect and awareness it requires from leadership and pilots because of historically inac...

The design requirements for a next-generation commercial aircraft can do much to secure its fate as a success or failure. New aircraft are often designed to meet or surpass the capabilities of an existing aircraft they are intended to replace. However, in the case of unconventional aircraft, this could lead to significant overdesign resulting in nonviable concepts. Instead, a method of analyzin...

ai = time aircraft i lands after the preferred landing time Pi (i 1; . . . ; N) bi = time aircraft i lands before the preferred landing time Pi (i 1; . . . ; N) C = cost coefficient vector defined in the linear programming problem Ei = earliest landing time for aircraft i (i 1; . . . ; N) fi = penalty cost per unit of time if aircraft i lands before the preferred landing time Pi (i 1; . . . ; N...

This paper describes an integrated solution to traffic conflict detection and resolution with weather avoidance in the Center-TRACON Automation System. An automatic conflict resolution algorithm developed and tested to resolve aircraft-to-aircraft conflicts is modified to reroute aircraft around convective weather constraints while avoiding traffic conflicts. The approach extends algorithms whi...

General aviation (GA) accounts for more than 82% of all air transport-related accidents and air transport-related fatalities in the U.S. In this study, we conduct a series of statistical analyses to investigate the significance of a pilot's gender, age and experience in influencing the risk for pilot errors and fatalities in GA accidents. There is no evidence from the Chi-square tests and logis...

In the process of the optimum design of aprons, solutions should be found for problems and such issues as the optimum area and dimensions of the apron, including the passenger and the cargo the number and dimensions of the gates on the basis of different types of aircraft parking configuration aircraft simulation and arrangement in different time periods of the given day at the airport. In this...

The behaviour of Escherichia coli O157:H7 was studied during the manufacture and storage of Iranian white cheese in brine. Cheese was manufactured using pasteurized cow milk and inoculated with E. coli O157:H7 with inoculum level of 103 cfu/ml. Four treatments were designed. Cheeses were made with or without starter culture and kept immersed in 6 or 8% salt brine during ripening and storage. Ch...

In this paper, the use of continuous mathematical models of an aircraft in an aircraft simulator is described. The models are of lower degree and less time-consuming for calculation. Computer implementation of the models capable to work faster and more accurately and efficiently is also described. The suggested approach allows to achieve the required precision at accelerated simulation speed us...

Monitoring the behavior of people in complex environments has gained much attention over the past years. Most of the current approaches rely on video cameras mounted on buildings or pylons and people are detected and tracked in these video streams. The presented approach is intended to complement this work. The monitoring of people is based on aerial image sequences derived with camera systems ...
