abstract: This thesis uses an aircraft aerodynamic model and propulsion data, which represents a configuration similar to the Airbus A320, to perform trade studies to understand the weight and configuration effects of “out-of-trim” flight during takeoff, cruise, initial approach, and balked landing. It is found that flying an aircraft slightly above the angle of attack or pitch angle required for a trimmed, stabilized flight will cause the aircraft to lose speed rapidly. This effect is most not...

The development of large lightweight airframes has resulted in what used to be high frequency structural dynamics entering the low frequency range associated with an aircraft’s rigid body dynamics. This has led to the potential of adverse interactions between the aeroelastic effects and flight control, especially unwanted when incidents involving failures or extreme atmospheric disturbances occur. Moreover, the pilot’s response in such circumstances may not be reproducible in simulators and uniq...

Mineralogical complexity and declining ore grades poses new challenges to the mining industry. From the grinding point of view, this means that in order to liberate minerals, particles would have to be ground to a finer particle size. Already, comminution is the biggest energy consumer in the concentrating mill. When particles are ground to even smaller particles sizes, costs and energy consumption increase significantly. This coupled with the fact that conventional tumbling mills are ineffectiv...
