Faa Letter In Response To White House Letter Regarding Faa Changes To Air Traffic Control Specialist Hiring Process, Tim Brady, Gregory Mcguirk
Faa Letter In Response To White House Letter Regarding Faa Changes To Air Traffic Control Specialist Hiring Process, Tim Brady, Gregory Mcguirk
Publications
On July 18, 2014, you submitted a letter to President Obama regarding the Federal Aviation Administration's (FAA) recent changes to the Air Traffic Control Specialist (ATCS) hiring process. You expressed concern with the FAA's decision to implement a single all sources hiring strategy and, as a result, you feel that it has disadvantaged graduates who successfully completed the Air Traffic Collegiate Training Initiative (AT-CTI) program, such as xxx. You also expressed concern with the implementation of the Biographical Assessment. Your letter was forwarded by the White House to our agency to address your concerns.

This report describes work that was done under AFOSR Contract Number FA9550-11-1-0056, studying the structure of a model urban boundary layer flow. The model geometry consisted of a set of plexiglass blocks, and the flow around this geometry was studied both experimentally as well as computationally. For the experiment, a Stereoscopic Particle Image Velocimetry (SPIV) method was developed that allows for a three-dimensional description of this urban flow, and helps gain insight into the characteristic flow structures in the streets and canyons of our model urban geometry. On the computational side, a new spectral-element code was developed that was demonstrated …
Multi-Stage Axial Compressor With Counter-Rotation Using Accessory Drive, Vinod Gehlot, Magdy S. Attia
Multi-Stage Axial Compressor With Counter-Rotation Using Accessory Drive, Vinod Gehlot, Magdy S. Attia
Publications
A multi-stage axial compressor for counter rotation. A first series of rotor blade assemblies are mounted on and rotate with the driveshaft, each rotor blade assembly of the first series comprising a rotating stage of the multi-stage axial compressor. A second series of rotor blade assemblies provide a counter-rotating stage of the multi-stage axial compressor. An accessory drive links the second series of rotor blade assemblies to the driveshaft and causes counter-rotation of the second series of rotor blade assemblies.

On Uav Robust Nonlinear Control In Presence Of Parametric Uncertainties, Vladimir V. Golubev, William Mackunis

We examine a new robust nonlinear flight control technology that employs an array of synthetic-jet micro-actuators embedded in UAV wing design in order to completely eliminate moving parts (such as ailerons) thus greatly enhancing maneuverability required for small fixed-wing air vehicles operating, e.g., in tight urban environments. Estimated fast response times are critical in mitigating gust effects while greatly improving flight stability and control. The new controller design is particularly advantageous for high levels of uncertainty and nonlinearity present both in the unsteady flowpath environment and in the embedded actuator’s response. The current work focuses on a benchmark case of …

Small Solar System bodies such as asteroids, comets and Mars' moons Phobos and Deimos have relatively unknown regolith environments. It is hypothesized that dust preserved in the regolith on the surfaces will have similar mechanical properties to lunar dust because of similar formation processes from micrometeoric bombardment, low relative gravity for slow settling times, and virtually no weathering because there is no atmosphere.
Space Shuttle Case Studies: Challenger And Columbia, Scott L. Post
Space Shuttle Case Studies: Challenger And Columbia, Scott L. Post
Publications
The two Space Shuttle tragedies, Challenger and Columbia, have led to many papers on case studies on engineering ethics. The Challenger disaster in particular is often discussed due to the infamous teleconference that took place the night before the launch in which some engineers tried to postpone the launch. However, the space shuttle program itself is worthy of study as it relates to the engineering design process, and the details of the Challenger and Columbia disasters are worthy of discussion as they relate to a variety of sub-disciplines, including material science, thermodynamics, fluid mechanics, and heat transfer. This paper summarizes …

A wide range of legislation has been proposed or put into place that restricts the use of unmanned systems. These actions by legislators and regulators will stifle the growth of this technology and the associated surrounding industry. The largest obstacle to the proliferation of UAS in the U.S. is the FAA. The FAA has designated the location of six test sites that are anticipated to allow for less restrictive and formative research to assess the technologies that the FAA has claimed need to exist in order to integrate UAS into the NAS. Further complicating the adoption of UAS for beneficent …

White Paper On Tuition Based Ab Initio Training Programs For Air Traffic Controllers, Tim Brady, Gregory Mcguirk
Publications
Embry-Riddle Aeronautical University is proposing an evaluation to transform the legacy method for hiring and training air traffic controllers. This evaluation will examine a transition to a prospective employee-funded, tuition-based model, while reinvesting savings to create a state-of-the-art air traffic training center at the FAA Academy in Oklahoma City.
Space Tourism: Hurdles And Hopes, Robert A. Goehlich
Space Tourism: Hurdles And Hopes, Robert A. Goehlich
Publications
According to the Space Policy Institute (2002, Bib. section), “Space tourism is the term broadly applied to the concept of paying customers traveling beyond Earth’s atmosphere.” Operating reusable launch vehicles (RLVs) might be a first step toward achieving mass space tourism. Thus, the aim of this article is to investigate the potential hurdles and other aspects of importance that must be overcome in order to use RLVs for space tourism flights. The primary ones are social issues (e.g., “Is space tourism ethically acceptable?”), institutional issues (e.g., “Is environmental pollution caused by space tourism more harmful than other emission sources?”), and …
