Collapse Introduction to Uncertainty Quantification and Industry Challenges
Uncertainty is an inescapable reality that can be found in nearly all types of engineering analyses. It arises from sources like measurement inaccuracies, material properties, boundary and initial conditions, and modeling approximations. With the increasing complexity and more demanding requirements for engineered systems, it has become vital to include Uncertainty Quantification (UQ) in engineering analysis. This webinar will introduce stochastic methods and UQ tools, discuss potential implementations in an industry setting, and use case studies to demonstrate the benefits of going beyond deterministic analysis.
 
The competitive benefits of UQ include reduced development time and cost, improved designs, better understanding of risk, and quantifiable confidence in analysis results and engineering decisions. Unfortunately, there are obstacles and technical challenges which can prevent organizations from utilizing UQ methods and techniques in their engineering practice. This webinar will discuss these challenges as well as strategies for addressing them.

Collapse Thermal Modeling and Regenerative Cooling of Liquid Rocket Engines
Thermal analysis is an essential and integral part in the design of rocket engines. In the high-pressure engines hot-gas temperatures are very high (they can reach 7000R at the throat area). It is therefore essential to be able to estimate the wall temperature and ensure that the material can withstand such high temperature. Furthermore, an accurate thermal model enables an engine designer to modify the cooling channel configuration for the optimum cooling at high temperature areas. This course presents an overview of various methods for thermal modeling of cooling liquid engines. The cooling methods include: regenerative, film, transpiration, radiative and dump cooling. Simple as well comprehensive computer models are discussed. The participant at the end of this webinar will be able to develop their own rocket thermal analysis model using available public domain software or use existing comprehensive computer programs.

Collapse Electric Aircraft Design Fundamentals: Enabling Technologies and Analysis Methods for More-, Hybrid-, and All-Electric Aircraft
This webinar introduces the technologies, fundamental concepts, and trade-offs involved in the design and analysis of electrical systems for More-/Hybrid-/All-Electric Aircraft, for which improvements to reliability, cost, performance, environmental impact, and significant mission fuel burn reductions have been theorized and/or demonstrated. It targets aerospace industry engineers who may lack significant expertise with aircraft electrical systems.
 
Material is presented at an introductory level and is accessible to those without a deep electrical engineering background, although a working knowledge of electromechanics and physics is assumed. Topics covered may include: current trends in More-/Hybrid-/All-Electric Aircraft; electromechanical energy conversion; enabling power electronics (devices, circuits, design); trends in MW-scale machines and drives; power distribution and protection systems;
thermal management; modeling and simulation of large integrated systems; and general More-/Hybrid-/All-Electric propulsion design considerations. The topics are modular and the emphasis given to individual topics can be tuned to match the interest of the attendees.

Collapse High Order CFD Methods: Results and Advancements from the 5th International Workshop
In January 2018, The 5th International Workshop on High-Order CFD Methods took place with the goal of providing an open and impartial forum for evaluating the status of high-order methods (order of accuracy > 2) in solving a wide range of flow problems.  
 
The objectives of the workshop were to:
·Assess the performance of high-order methods through comparison to production 2nd-order CFD codes widely used in the aerospace industry with well-defined metrics.
·Support new research in the field of high-order CFD methods by providing validation cases and aid during development and improvement of codes.
·Identify pacing items in high-order methods and peripheral tools that need additional research and development in order to proliferate in the CFD community.
·Facilitate international collaboration and enhance mutual understanding among CFD researchers and managers in academia, government, and industries.
 
This Webinar will showcase the key results of that workshop, including advancements, concerns, and demands.

Collapse Aircraft and Rotorcraft System Identification Engineering Methods for UAV Applications
System identification methods are ideally suited for rapidly determining bare-airframe simulation models of fixed-wing and rotorcraft UAVs, since UAV configurations change widely throughout their development process. Also the parameters needed for a physics-based model are often poorly known for UAVs, or the modeling assumptions do to correspond well to the physical characteristics of modern UAV configurations. A full-flight envelope UAV simulation can be obtained from “stitching” together only a few point identification models, obtained from a very limited flight-testing program. This webinar will review the fundamentals of the frequency-response method for UAV aircraft and rotorcraft system identification.  Special methods are needed for modern multi-copter or eVTOL configurations with highly redundant controls. Identifications methods and results are illustrated with many recent UAV examples. Particular emphasis is given to the important role of system identification in UAV flight control development, implementation verification, and documentation of performance.  The course will review key methods, computational tools, and complimentary reference material. The lecture material will be followed by a question and answer period.

Collapse Predictive Maintenance with MATLAB: A Data-Based Approach
Companies that make industrial equipment are storing large amounts of machine data, with the notion that they will be able to extract value from it in the future.  However, using this data to build accurate and robust models that can be used for prediction requires a rare combination of equipment expertise and statistical know-how.  
 
In this 75-minute webinar we will use machine learning techniques in MATLAB to estimate remaining useful life of equipment while highlighting some newer features and toolboxes. Using data from a real-world example, we will explore importing, pre-processing, and labeling data, as well as selecting features, and training and comparing multiple machine learning models.  We will show how MATLAB is used to build prognostics algorithms and take them into production, enabling companies to improve the reliability of their equipment and build new predictive maintenance services.
 
Attendees will be able to have their MATLAB questions answered at the end of the presentation.

Collapse Testing Large Ultra-Lightweight Spacecraft
Large,ultra-lightweight spacecraft technology has continued to mature, as witnessed by:
·Deploying larger space platforms from smaller packed volumes, with fewer moving parts and more strain energy enforcements
·Deployment articulations becoming more complex, with more degrees of freedom
·Precision space structures growing larger, forcing flight qualification at the sub-scale level
 
This 90-minute Webinar is focused on the novel testing approaches and challenges that are unique to large ultra-lightweight space platforms.  The scope of the discussion is to illuminate both the theory and especially the practice of testing large, ultra-lightweight spacecraft.  The webinar is based on the recently published "Testing Large Ultra-Lightweight Spacecraft" (AIAA, 2017).
 
These structures are typically not self-supporting in the terrestrial gravity environment, requiring counterbalances or other measures to simulate zero-gravity in ground tests and during performance measurements.  Heritage metallic hinged architectures are represented alongside more advanced strain-energy composite deployed systems, and laminated plate apertures are included alongside tension-aligned membrane and mesh systems.
