Mary Jackson Lecture: A Wandering Fluid Mechanics Scientific Career

On-Demand Recording Available

In this seminar, Ivett Leyva, Ph.D., P.E. will describe her remarkable career journey, which has led her to study various fluid mechanics problems, as well as the challenges and rewards of holding management and leadership positions. She will discuss topics related to preventing rocket explosions, including the construction of hazardous facilities for testing rocket propulsion and enhancing the scientific understanding of hypersonic flight. Leyva will also share insights from two hypersonic flight experiments she initiated at the Air Force, along with the portfolio she managed. Finally, she will conclude with her experiences as department head and her current efforts to establish a new research enterprise aimed at addressing applied research challenges from industry while tailoring graduates to meet industry needs.

The Mary Jackson Named Lecture is given in honor of Mary Jackson (1921–2005), who became the first black female aerospace engineer at NASA in 1958. The lecture is jointly sponsored by the Royal Aeronautical Society and AIAA.

Multiple-Time-Scale Nonlinear Output Feedback Control of Systems With Model Uncertainties by Dr. John Valasek

Abstract: The Geometric Singular Perturbation theory is a powerful control law development tool for multiple-timescale systems because it provides physical insight into the evolution of the states in more than one timescale. This presentation presents the theory for a nonlinear, multiple-time-scale, output feedback tracking controller for a class of nonlinear, nonstandard systems with slow and fast states, slow and fast actuators, and model uncertainties. The class of systems is motivated by aircraft with uncertain inertias, control derivatives, engine time-constant, and without direct measurement of angle-of-attack and sideslip angle.

Information front-end of aerospace systems: recent advances and experiences by Dr. Manoranjan Majji

Abstract: Recent advances in information fusion and smart sensing technologies for relative navigation of aerospace vehicles are discussed. Sensor physics and information processing principles to integrate vision-based sensor data with inertial measurements are presented, along with discussions associated with signal processing of an ultra-precise optomechanical accelerometer being developed at Texas A&M. The talk also discusses aeromagnetic sensing and localization approaches as potential alternatives to the global positioning system based approaches for localization.

Lunch and Learn: Predicting Heating Rates in Hypersonic Gap Flows with Guest Speaker Ms. Laura Holifield

The Dayton/Cincinnati Section offers a presentation that showcases a study investigating the flow structure in the vicinity of discontinuities at the surface of a high-speed air vehicle, with the effect of gaps and steps on aerodynamic heating of particular interest. Laura Holifield works as a researcher at the Air Force Institute of Technology, employed via the Oak Ridge Institute for Science and Education. She works within AFRL in the High Speed Systems Division, Fundamental Research Branch (AFRL/RQHF), with a research focus on hypersonic aerodynamics
