Title of Webinar: Why Birds Don’t Have Vertical Tails
Abstract: For nearly a century Ludwig Prandtl’s lifting-line theory remains a standard tool for understanding and analyzing aircraft wings. The tool, said Prandtl, initially points to the elliptical spanload as the most efficient wing choice, and it, too, has become the standard in aviation. Having no other model, avian researchers have used the elliptical spanload virtually since its introduction. Yet over the last half-century, research in bird flight has generated increasing data incongruous with the elliptical spanload. Based on research we present a unifying theory for superior efficiency and coordinated control in a single solution.

Title of Webinar: Space Biology of Human Space Exploration
Abstract: Humans are naturally curious. We all like to explore the world around us, and we have all looked up at the night sky and asked, “what is out there and beyond the bounds of gravity?” Over the past several decades we have sent unmanned probes into the deeps of space and sent humans on scientific missions to the moon and around the Earth to find the answers to these questions. From the early days of human space exploration, scientists have observed changes in physiological functions, such as bone loss and immune dysfunction. Finding the answers to the root cause of these physiological changes is critical for safe long duration and deep space exploration by humans and for commercialization. This presentation will give an overview of the space biology of human space exploration and associated areas of biological research that are being conducted. Also, it will provide a view of the scientific, engineering, operational, and administrative capabilities and work that goes into conducting a scientific research mission for the International Space Station and beyond.

Title of Webinar: Curiosity’s Entry Descent and Landing on Mars Abstract: On August 5th 2012, NASA landed its most capable robotic geologist on the surface of the Red Planet. The Mars Science Laboratory (MSL) mission landed a 2000 lb rover, the size of a compact car, to explore the planes of Mars. The rover, aptly named Curiosity, will search for organic compounds, characterize the climate and geology, and continue the search for life. One of the most challenging aspects of the mission, from an engineering perspective, was safely landing the rover on the surface. The entry descent and landing (EDL) system used a heat shield to accommodate its hypersonic entry conditions, followed by a supersonic parachute, and eight retro rockets for the powered descent phase. For its final terminal descent, a maneuver called the sky crane was used where the rover was lowered on tethers for touchdown. The talk will describe the motivation for Mars Exploration and how the MSL EDL engineering challenges were tackled with computational modeling and cutting edge experimental techniques.

Title of Webinar: Rapid State Space Modeling Tool for Rectangular Wing Aeroservoelastic Studies and Modal Filtering for Control of Flexible Aircraft
Abstract: This presentation introduces a modeling and simulation tool for aeroservoelastic analysis of rectangular wings with trailing edge control surfaces. The inputs to the code are planform design parameters such as wing span, aspect ratio, and number of control surfaces. Using this information, the generalized forces are computed using the doublet lattice method. Using Roger’s approximation, a rational function approximation is computed. The output, computed in a few seconds, is a state space aeroservoelastic model which can be used for analysis and control design. The tool is fully parameterized with default information so there is little required interaction with the model developer. All parameters can be easily modified if desired.
Modal regulators and deformation trackers are designed for an open-loop fluttering wing model in this presentation. The regulators are designed with modal coordinate and accelerometer inputs respectively. The modal coordinates are estimated with simulated fiber optics. The robust stability of the closed loop systems is compared in a structured singular-value vector analysis. Performance is evaluated and compared in a gust alleviation and flutter suppression simulation. For the same wing and flight condition two wing-shape-tracking control architectures are presented, which achieve deformation control at any point on the wing.

His dissertation was titled “A fast ascent trajectory optimization method for hypersonic air-breathing vehicles.”
Title of Webinar: On the Minimum Induced Drag of Wings
Abstract: Of all the types of drag, induced drag is associated with the creation and generation of lift over hide wings. Induced drag is directly driven by the span load that the aircraft is flying at. The tools by which to calculate and predict induced drag we use were created by Ludwig Prandtl in 1903. Within a decade after Prandtl created a tool for calculating induced drag, Prandtl and his students had optimized the problem to solve the minimum induced drag for a wing of a given span, formalized and written about in 1920. This solution is quoted in textbooks extensively today. Prandtl did not stop with this first solution, and came to a dramatically different solution in 1932. Subsequent development of this 1932 solution solves several aeronautics design difficulties simultaneously, including maximum performance, minimum structure, minimum drag loss due to control input, and solution to adverse yaw without a vertical tail. This presentation lists that solution by Prandtl, and the refinements by Horten, Jones, Kline, Viswanathan, and Whitcomb.

Title of Webinar: Exploring the Arctic with Under-Ice Rovers
Abstract: Underneath the Arctic ice lies unexplored terrain – one as treacherous as the lunar surface, yet harboring lifeforms that may be similar to what we could find on other worlds. Our team has been exploring shallow lakes and sea ice near the “top-of-the-world” with both sampling mechanisms, and a brand new robotic rover, able to drive upside-down on the underside of this ice. The rover allows us to have a virtual view of this new terrain, and learn how to explore icy-worlds elsewhere in the solar system. In this talk, we’ll discuss challenges of arctic expeditions, and the successes we’ve had with the Buoyant Rover. The close ties with astrobiology, geology, and climate science will also be illustrated to show how a complicated engineering design really goes back to a very simple hypothesis.

Title of Webinar: Nanotechnology-enabled Bio and Chemical Sensors for NASA Missions
Abstract: NASA missions require sensor technologies that are compact, light-weight and with low power consumption while maintaining high sensitivity. The use of nanomaterials and nanotechnology helps NASA achieve this requirement. Carbon nanotubes (CNTs) have shown interesting electronic, mechanical, optical, thermal, and other properties and therefore have been pursued for a variety of applications by the nanotechnology community ranging from electronics to nanocomposites. We have been pursuing development of chemical and biosensors using carbon nanotubes for the last several years and this talk will present our progress to date.
In the case of the biosensor, a “lock and key” approach is used wherein a preselected probe for a given target is attached to the tip of a carbon nanofiber (CNF). CNFs in a patterned array are grown using plasma chemical vapor deposition on a silicon wafer, which serve as individual, freestanding, vertical electrodes. This nanoelectrode array (NEA) can use DNA, aptamer and antibody probes, and electrochemical impedance spectroscopy is used upon probe-target binding for signal analysis. Results will be presented for identification of protein markers for cardiac health analysis using this NEA. Applications include water and food quality monitoring, environmental monitoring, biothreat detection, and lab-on-a-chip for point of care needs
In the case of chemical sensors, we use an interdigitated electrode as a chemiresistor, where purified single-walled carbon nanotubes (SWCNTs) serve as the conducting medium. When the chemiresistor is exposed to a gas or vapor, the change in resistance is recorded; if SWCNTs do not respond to a particular gas or vapor, then doping or functionalization strategies are used. A sensor array is constructed with 32-96 sensor elements with chemical variations across the sensor array. In the sensor training mode, a pattern of resistance changes is generated from the sensor array for a particular analyte at a given concentration and humidity level; this needs to be repeated for various concentrations and humidities and the generated information is stored for later use. In the identification mode, a pattern recognition algorithm is used to identify that analyte from the background using the information stored during training. This talk will present examples from our work to demonstrate the functioning of the sensor. This sensor has also been miniaturized and integrated in an iPhone which will be described.

Title of Webinar: Advances in CubeSat Swarm Technology
Abstract: A growing community of scientists are interested in collecting data from multiple points in low Earth orbit (LEO), necessitating the production and management of swarms or constellations of spacecraft. The budgetary constraints currently levied on many space organizations makes the use of smaller spacecraft for these science missions ideal, however using comparatively small spacecraft is not without its consequences. In particular, these spacecraft are subject to much stricter mass, volume, and power constraints, making integration and operation of advanced science payloads more complicated. This presentation will study the challenges and constraints associated with deploying a swarm of CubeSat-class spacecraft into LEO for the purpose of performing a simple space weather experiment.
