The Development Of A Phase Locked Wind Turbine Blade Finite Element Model To Predict Loads And Deflections During Fatigue Testing, Kyle Freeman

Master's Theses - Daytona Beach

Full scale blade testing provides blade manufacturers with quantitative data in order to assess blade design, manufacturing and durability. Structural testing is a requirement in order to design reliable blades, and to develop a further understanding of the dynamics involved in a modern turbine blade. Blade tests can be conducted in either a single axis or dual axis configurations. Historically, fatigue testing has been performed by utilizing forced displacement systems. These systems do not allow for the load phase angle to be controlled, and the maximum load application in the edge and flap directions are allowed to vary. The PhLEX …

The Development Of An Adaptive Control System For A Phase-Locked Excitation (Phlex) Method For Advanced Wind Turbine Blade Fatigue Testing, William Michael Haupfear

Master's Theses - Daytona Beach

The National Renewable Energy Laboratory's (NREL) National Wind Technology Center (NWTC) provides the means necessary for advanced wind turbine blade testing. To improve on the current testing methods, a new testing method is being developed using the existing dual-axis fatigue testing capabilities in conjunction with another actuator to provide a phase-locked excitation method with adaptive algorithms and advanced control system strategies. This testing method will provide a more representative loading of the blade for fatigue testing as compared to loading seen in the field. The control system will integrate the MTS software and controller with a supervisory controller, programmed in …

Integrating Second Life Into A Chinese Language Teacher Training Program: A Pilot Study, Hsiu-Jen Cheng, Hong Zhan, Andy Tsai

Publications

Second Life (SL), a 3-D Multi-User Virtual Environment, has been found beneficial to foreign language education because of its immersive and interactive environments. This cross-continental study explored feasibilities of using Second Life to provide field experiences to pre-service Mandarin teachers in a program of Teaching Chinese as a Foreign Language in Taiwan. This study also investigated pre-service teachers‘ insights of teaching Chinese in such a virtual environment, as well as the difficulties these teachers encountered when integrating Second Life in teaching Chinese. The study found that the more teaching experience the pre-service teachers gained in teaching Chinese in Second Life, …

Gravity Couplings In The Standard-Model Extension, Quentin G. Bailey

Publications

The Standard-Model Extension (SME) is an action-based expansion describing general Lorentz violation for known matter and fields, including gravity. In this talk, I will discuss the Lorentz-violating gravity couplings in the SME. Toy models that match the SME expansion, including vector and two-tensor models, are reviewed. Finally I discuss the status of experiments and observations probing gravity coefficients for Lorentz violation.

A Comprehensive Rocket And Radar Study Of Midlatitude Spread F, G.D. Earle, P. Bhaneja, P.A. Roddy, C.M. Swenson, A. Barjatya, R. L. Bishop, Et. Al

Publications

An instrumented sounding rocket launched from Wallops Island Virginia has flown through a midlatitude spread F (MSF) event in conjunction with simultaneous ionosonde, HF radar, and 244 MHz scintillation observations from the ground. The in situ measurements include the electric field, horizontal neutral wind, and plasma density within the spread F region. The ground‐based HF radar measurements of wave signatures in the bottomside F region ledge reveal the presence of waves propagating to the north and northwest prior to and during the spreading event. The periods of these bottomside waves range from 16 to 60 min, and they are shown …

Nanoindentation And Plasticity In Nanocrystalline Ni Nanowires: A Case Study In Size Effect Mitigation, F. Sansoz, Virginie Rollin

Publications

We examine the processes of spherical indentation and tension in Ni nanowires and thin films containing random distributions of nanoscale grains by molecular dynamics simulations. It is shown that the resistance to nanoindentation of nanocrystalline Ni nanowires with diameters of 12 and 30 nm tends not to depend on the wire diameter and free surfaces, contrary to nanoindentation in single-crystalline nanowires. Accommodation of plastic deformation by grain boundary sliding suggests a mitigation strategy for sample boundary effects in nanoscale plasticity.

The November 2010 Elections: Verification And Nuclear Weapons Reduction, Ibpp Editor

International Bulletin of Political Psychology

The author discusses the results of the November 2010 elections in the United States (US), the transition of power between two very different Senates, and US participation in international treaties pertaining to nuclear weapons. Of note, are the roles of and problems with the idea of verification as per modern logical positivism.

Oh And Oi Airglow Layer Modulation By Ducted Short-Period Gravity Waves: Effects Of Trapping Altitude, Jonathan B. Snively, Victor P. Pasko, Michael J. Taylor

Publications

Perturbations to the OH and OI [O(1S) 557.7 nm] airglow layers by ducted gravity waves near the Brunt‐Väisälä period are investigated using a 2‐D numerical model. Airglow signatures of these waves are strongly determined by perturbations of O, O3, and H, which exhibit peak densities near and above mesopause. Strong periodic vertical wind components of short‐period gravity waves induce opposite relative density perturbations above and below the layer density peaks. Airglow signatures for ducted waves depend on the specific vertical shapes and altitudes of the wave packets relative to ambient species density profiles; waves perturbing only the bottoms or tops …

The U2 Spy Plane Crisis: Turning Point In The Cold War, William Weiss

ERAU Prescott Aviation History Program

When the Soviets shot down Francis Gary Powers’ U2 spy plane in 1960, it caused an international crisis. Thanks to recently declassified US and former Soviet archives, we can now hear the inside story of what really happened as told by an American History writer & lecturer.

Developing Proactive Methods For General Aviation Data Collection, Scott Shappell, Carla Hackworth, Kali Holcomb, John Lanicci, Massoud Bazargan, Jaclyn Baron, Rebecca Iden, Daniel Halperin

Publications

Introduction. Over the last 20 years, nearly 40,000 general aviation (GA) aircraft were involved in accidents, roughly 20% of which were fatal. To address this safety concern, scientists have often relied on accident data. Because of the rare nature of accidents, commercial aviation incident and near miss data may prove to be useful sources of safety information. In one such study, the National Transportation Safety Board interviewed GA pilots that were flying near a weather-related accident in pursuit of a different perspective than that of the accident pilot. Interviewing GA pilots about their own weather-related event may provide similar …
