Model Predictive Power Management Of A Hybrid Electric Propulsion System For Aircraft, Tyler J. Wall
Model Predictive Power Management Of A Hybrid Electric Propulsion System For Aircraft, Tyler J. Wall
Masters Theses
This work presents the switched optimal power flow control for an aircraft with a hybrid electric propulsion system. The propulsion system is a switched system that operates in either of two modes: (i) battery discharging and electric motor propelling and (ii) battery charging and electric motor generating. The aircraft model and components that form the hybrid propulsion system are modeled as either an algebraic power source/sink or as a dynamic model with appropriate power and state interconnections. With the system model defined, a model predictive control power management strategy is set fourth which minimizes a performance index that includes altitude …
Six Degrees Of Freedom From Six Degrees Of Separation: The History Of Flight Simulators, David Keck, Morgan Lopez
Six Degrees Of Freedom From Six Degrees Of Separation: The History Of Flight Simulators, David Keck, Morgan Lopez
Publications
Some of today's advanced flight simulators have the capacity to provide pilots with experiences of six degrees of freedom: forward/backward, up/down, or left/right (or pitching, rolling, or yawing in either direction). These incredible devices are the product of over 100 years of design developments that come from a series of technological discoveries and historical events.
Optimum Design Of Composite Wing Spar Subjected To Fatigue Loadings, Juan Reuben Lazarin
Optimum Design Of Composite Wing Spar Subjected To Fatigue Loadings, Juan Reuben Lazarin
Master's Theses
Composites are now being incorporated into aircraft designs because of their high strength to weight ratio compared to traditional metal materials. Due to the complexity of the material, composite parts are presently being over designed to satisfy static and fatigue requirements. A greater understanding of composite fatigue behavior will allow for even greater weight savings leading to increased fuel economy. A critical part of an aircraft that is subjected to fatigue bending loads are its wings. The forces acting on the wings include its lift distribution, powerplant, and fuel which can be carried in the wing body. When in flight …

Specialist Communities In China’S Aerospace Technology And Innovation System: The Cultural Dimension, Alanna Krolikowski
Specialist Communities In China’S Aerospace Technology And Innovation System: The Cultural Dimension, Alanna Krolikowski
History and Political Science Faculty Research & Creative Works
Only two decades ago, China was a marginal player in the global aerospace industry. Today, the pace of China’s space programs is unparalleled and it has joined the sector’s leading ranks. China is the only country after the Soviet Union/Russia and the United States to independently send humans into orbit and a rover to touch down on the Moon. A Chinese station will likely soon be only the only long-term human habitat circling the Earth alongside the International Space Station. Within a decade, China could become only the second country in history to land a person on the Moon’s surface. …

A Method For Evaluating Aircraft Electric Power System Sizing And Failure Resiliency, Cory Kenneth Kross
A Method For Evaluating Aircraft Electric Power System Sizing And Failure Resiliency, Cory Kenneth Kross
Master's Theses
With the More Electric Aircraft paradigm, commercial commuter aircraft are increasing the size and complexity of electrical power systems by increasing the number of electrical loads. With this increase in complexity comes a need to analyze electrical power systems using new tools. The Hybrid Power System Optimizer (HyPSO) developed by Airbus SAS is a simulator designed to analyze new aircraft power systems. This thesis project will first provide a method to assess the reliability of complex aircraft electrical power systems before and after failure and reconfiguration events. Next, an add-on to HyPSO is developed to integrate the previously developed reliability …
