| Presenter | Federico Semeraro |

| Published | March 2023 |
| Recorded | June 2022 |
| Duration | 59:48 |
| Tags | None |
Abstract:<br>This talk discusses the capabilities of an open-source, NASA-developed software called Porous Microstructure Analysis (PuMA). The code was developed to provide a robust and efficient framework for computing material properties based on 3D microstructures. The development was motivated by advancements in X-ray microtomography, an imaging technology that can resolve the structure of a material at a sub-micron scale, in 3D and even in 4D (over time). At NASA, this technique has provided unprecedented insights into materials relevant for different missions, from heat shields, to parachute fabrics, to meteorites and other advanced composites. PuMA provides the ability to compute a comprehensive spectrum of material properties, from the most fundamental geometric features of a microstructure, to advanced anisotropic thermo-elastic and chemical properties. In addition, the software can generate artificial microstructures, including complex fibrous woven and non-woven geometries, allowing to perform optimization studies that inform the design of new materials.

Discipline: Flight Mechanics<br><br>Kane's method of formulating dynamical equations of motion has proved especially useful for dealing with the complex multibody mechanical systems that in the twentieth and twenty-first centuries have challenged engineers in industry, government, and universities: the Galileo spacecraft sent to Jupiter, the International Space Station, and the robotic manipulator arms aiding astronauts on the Space Shuttle and International Space Station are but a few examples. The method is systematic and easily taught. The basic apparatus of Kane's method is presented, and then applied in examples involving a single particle, a single rigid body, two connected rigid bodies, and a nonholonomic system. Brief comparisons between Kane's method and other classical methods are made throughout.<br><br>About the Speaker:<br>Carlos M.

| Tags | #Intermediate, #State of the Art, ~Induced Environments, .Analysis / Modeling and Simulation, .Design, ~Performance, ~Monte Carlo, ~Order Statistics, ~Meeting Requirements, ~Design Analysis |
Abstract:<br>This presentation will include a description of statistical methods to derive models of launch vehicles that can be used during design phases in order to demonstrate that performance requirements will be met, and in order to derive driving design parameters that can be used to define what environments and other parameters the vehicle must endure. The approaches developed in this paper can be applied to other complex design efforts as well. This paper also explains a method (order statistics) for determining whether certain probabilistic requirements are met and enables the user to determine how many Monte Carlo samples are required. These methods also apply to determining the design values of parameters of interest in driving the design.<br><br>About the Speaker:<br>John Hanson has been with NASA since 1990 after previously working at the ANSER Corporation on Air Force space projects. At NASA he spent over 20 years in the Flight Mechanics/GN&C discipline in areas of increasing responsibility. He was a team lead, Branch Chief, and Technical Assistant for the Division. He led Flight Mechanics/GN&C work on the X-33 and Ares projects. He led the Advanced Guidance and Control Project that led to the adaptive flight control being used for SLS, and developed the process being used for verifying probabilistic SLS requirements. He was the Alternate Lead Systems Engineer for SLS from 2011-2016, followed by detail assignments as SLS Deputy Chief Engineer, Vehicle Management Discipline Lead Engineer, Technical Assistant for the Structures and Environments Division, and Technical Assistant to the SLS Chief Engineer. <br><br>He was detailed to the NASA Office of Chief Engineer as the Deputy HEOMD Chief Engineer for Exploration Systems Development. Later he was Lead Systems Engineer for the Exploration Upper Stage, and is currently Deputy Chief Engineer for Systems Engineering and Integration in the Moon to Mars Program. He is an AIAA Associate Fellow and has received the AIAA De Florez Award for Flight Simulation, the Silver Snoopy Award, the NASA Exceptional Achievement Medal, the NASA Exceptional Service Medal, and other awards from NASA. He holds a Ph.D. in Aerospace Engineering from the University of Michigan.

Abstract:<br>A rapid mission analysis tool is developed to support the ongoing design of a Lunar Transit trajectory of the Power and Propulsion Element (PPE) between a Medium Earth Orbit (MEO) parking orbit and a lunar L2 southern Near Rectilinear Halo Orbit (NRHO). A parameterization is developed by which the Lunar Transit can be analyzed in the context of varying vehicle mass, solar electric propulsion (SEP) configurations, and solar array power output. A rapid and novel mission analysis tool enables a wide array of these trade analyses to be completed without the need for extensive computing resources or time.

Abstract:<br>The Simplified Vehicle Operations paradigm seeks to achieve significant reductions in pilot workload and training requirements through the holistic design of flight control laws, control inceptors, and cockpit displays. This talk investigates the paradigm in the context of vertical takeoff and landing urban air mobility flight vehicle concepts using piloted flight simulations.

This talk describes sizing of a lift-plus-cruise urban air mobility aircraft with all-electric, hybrid-electric, and turbo-electric propulsion systems using the Parametric Energy-based Aircraft Configuration Evaluator (PEACE) framework. The PEACE framework was developed at the Vehicle Systems, Dynamics and Design Laboratory (VSDDL) to allow sizing and performance analysis of novel configurations and propulsion system architectures. After assessing the sensitivities of the sized design to mission range and technology state-of-the-art, multi-objective optimization is performed using a genetic algorithm for a set of sizing scenarios.

Discipline: Flight Mechanics<br>Original Webcast Air Date: April 21, 2015<br>The rise of innovative unmanned aeronautical systems and the emergence of commercial space activities have resulted in a number of relatively new aerospace organizations that are designing innovative systems and solutions. These organizations use a variety of commercial off-the-shelf and in-house-developed simulation and analysis tools including 6-degree-of-freedom (6-DOF) flight simulation tools. The increased affordability of computing capability has made high-fidelity flight simulation practical for all participants.<br><br>Verification of the tools’ equations-of-motion and environment models (e.g., atmosphere, gravitation, and geodesy) is desirable to assure accuracy of results. However, aside from simple textbook examples, minimal verification data exists in open literature for 6-DOF flight simulation problems.<br><br>The NESC undertook an assessment that compared multiple solution trajectories to a set of verification check-cases that covered atmospheric and exo-atmospheric (i.e., orbital) flight. Each scenario consisted of redefined flight vehicles, initial conditions, and maneuvers. These scenarios were implemented and executed in a variety of analytical and real-time simulation tools. This tool-set included simulation tools in a variety of programming languages based on modified flat-Earth, round-Earth, and rotating oblate spheroidal Earth geodesy and gravitation models, and independently derived equations-of-motion and propagation techniques. The resulting simulated parameter trajectories were compared by over-plotting and difference-plotting to yield a family of solutions. In total, seven simulation tools were exercised.<br><br>The check cases and the generated family of solutions are now available for download from the NESC Academy web-site for use in cross comparison with other simulation tools. This webast will give an overview of the check-cases, the comparison approach, the types of differences remaining in the comparison set, and an introduction to the contents of the “flightsim” website where the check case descriptions and generated results are stored.

Abstract:<br>This talk deals with the development and optimization of a flight control system for a lift-plus-cruise urban air mobility aircraft that is based on the Total Energy Control System algorithm. The Modular Aircraft Dynamics and Control Algorithm Simulation Platform (MADCASP) framework is used to implement the aircraft simulation model and the flight control laws, whose parameters are then optimized. Maneuver simulations are analyzed to assess the behavior of the flight control system in preparation for subsequent piloted simulations.<br><br>Part two of a three part series.<br>
