Determination Of Human Powered Helicopter Stability Characteristics Using Multi-Body System Simulation Techniques, Sean M. Brown

Master's Theses

Multi-Body System Simulation combined with System Identification was developed as a method for determining the stability characteristics of a human powered helicopter(HPH) configurations. HPH stability remains a key component for meeting competition requirements, but has not been properly treated. Traditional helicopter dynamic analysis is not suited to the HPH due to its low rotation speeds and light weight. Multi-Body System Simulation is able to generate dynamic response data for any HPH configuration. System identification and linear stability theory are used to determine the stability characteristics from the dynamic response. This thesis focuses on the method development and doesn't present any …

STAR Program Research Presentations

The Telescope Assembly Alignment Simulator (TAAS) calibrates scientific instruments (SI’s) that are installed on the Stratospheric Observatory For Infrared Astronomy (SOFIA). An SI’s accuracy is directly dependent on the consistent performance of the TAAS, which has never been fully characterized. After designing various thermal and optical experiments to identify the current unknowns of TAAS, we now have a far better grasp on how the equipment behaves.

Nonlinear Uav Flight Control Using Command Filtered Backstepping, Brian M. Borra

Master's Theses

The aim of this effort is to implement a nonlinear flight control architecture, specifically flight path control via command filtered backstepping, for use in AME UAS's Fury® 1500 unmanned flying wing aircraft. Backstepping is a recursive, control-effort minimizing, constructive design procedure that interlaces the choice of a Lyapunov function with the design of feedback control. It allows the use of certain plant states to act as intermediate, virtual controls, for others breaking complex high order systems into a sequence of simpler lower-order design tasks.

Work herein is a simplified implementation based on publications by Farrell, Sharma, and Polycarpou. Online approximation …

The Art And Beauty Of Flight, Edmond Ing Huang Tan

The Hilltop Review

This picture nicely represents the art and gracefulness of flight with the beauty of sunset in a tranquil setting. In the picture is a powered paragliding, also known as paramotoring in the plains of Nebraska. The ability to fly both low and slow safely, the 'open' feel, the minimal equipment and maintenance costs, the portability, minimally regulated and requires no license are claimed to be this type of flying's greatest merits. Paramotors can be flown during any season of the year anywhere but not in high wind conditions which typically means at low Sun azimuths as shown in the picture …

Microgas Turbine Engine Characteristics Using Biofuel, Edmond Ing Huang Tan, William W. Liou

The Hilltop Review

Aviation fuels commonly used today are extracted from the kerosene fraction of the crude oil that is distilled between the gasoline and the diesel. Crude oil is not renewable and the world oil reserve is generally believed to be on the decline. In 2006, 6.3% of the world's refinery production was used for aviation fuel (Nygren et. al., 2009). At an estimated rate of 3% increase of fuel demand per year, aviation use alone will consume the world fuel production by 2026. Therefore, there is a need for the aviation industry to reduce its dependence on fossil fuels and, perhaps, …
