MAE Colloquium - Autumn 2013
The Aerospace Engineering Colloquium (AE 598) is a required course that satisfies the professional development component of the Master of Aerospace Engineering (MAE). MAE students are required to complete nine (9) credits of colloquium participation to satisfy the degree requirements. However, all students and faculty are welcome to attend.
Topics may include current research and advances in aerospace technology as well as other themes relevant to the professional development of aerospace engineers. To earn credit for this course, students must complete a required set of writing assignments.

Basics of Intellectual Property
- Andrew Graham, Patent Portfolio Manager
Center for Commercialization, University of Washington
Whether revered or reviled, intellectual property is often the subject of headline-grabbing news stories. But what exactly is it?
This talk is designed to inform students about the basics of intellectual property, including what it is and the process for obtaining it. Discussion will focus on patents and the requirements for protecting an inventive concept. Mr. Graham will also describe the services provided by the University of Washington Center for Commercialization to help members of the UW community make (or avoid) headlines.

On Blade Control of Rotor Vibration, Noise, and Performance - Just Around the Corner?
- Peretz Friedmann, Francois-Xavier Bagnoud Professor in Aerospace Engineering
Department of Aerospace Engineering, University of Michigan
A concise review of the evolution of active control approaches for vibration reduction in rotorcraft that have resulted in Higher Harmonic Control (HHC) and Individual Blade Control (IBC) will be presented. It will be shown that despite the success of these approaches, demonstrated by both full scale wind tunnel and flight tests, these implementations have not managed to earn their way onto a production helicopter. A more recent alternative, On Blade Control (OBC) is defined as a special implementation of IBC, where the control surfaces are located on the rotating blade and each blade has its own controller. The evolution and description of four OBC devices: (1) the actively controlled flap (ACF), (2) the active twist rotor (ATR), (3) the active tip (AT), and the (4) deployable Gurney flap, or microflap (MF), is presented. A detailed outline of an aeroelastic response modeling capability used to simulate active vibration and noise reduction using flaps or microflaps is presented. Next, selected scaled wind tunnel model tests are shown to produce excellent insight on the operational and modeling aspects of these systems. Full scale wind tunnel and flight tests are presented as culmination of the sustained research effort invested in research on OBC. The talk concludes with lessons learned and speculation about the potential implementation of OBC on production rotorcraft.

Pondus Hydrogenii - The Power of Hydrogen
- Jacob Leachman, Assistant Professor
School of Mechanical & Materials Engineering, Washington State University
Hydrogen is the high-performance fuel of choice for aerospace applications due to higher specific energy and increased utility over conventional chemical fuels. However, the extreme temperatures or pressures required to increase the energy density of hydrogen present substantial engineering challenges and opportunities. We will begin with quantum mechanical characteristics unique to hydrogenic molecules at cryogenic temperatures that have significant and tunable effects on macroscale thermophysical properties. My laboratory has, so far, utilized these traits for catalytic pressurization and vapor cooled shielding technologies. The heavy hydrogenic molecules of deuterium and tritium also exhibit these traits that can be exploited for the fueling of fusion energy machines. We are completing the development of a diagnostic twin-screw extruder for the continuous production of solidified thermonuclear fuel pellets. With this machine operational, plans are in place to continuously produce hydrogenic fuel mixtures, including cryogenic clathrates, which have energy densities up to two times higher than conventional RP-1. We will conclude with eventual system level testing of these hydrogen fuels in Genii– the first liquid hydrogen fueled drone completely designed, constructed, and operated by university students.
