Published on

Developing a practical vehicle that simultaneously satisfies road and aircraft regulations to become a true "flying car" presents significant engineering challenges. Yet this is what the team at Terrafugia has achieved with their proof-of-concept vehicle known as the Transition®, which has been flying and driving for the past 2 years. The next generation prototype is currently in development with the aid of simulation packages to allow for rapid design iteration before performing required physical tests.

Register for this webinar in which Terrafugia will discuss the design process for the composite structure of the Transition® airframe and the role and benefits of physics based simulation.

Developing the Transition®: Simulation for Composite Structure in a Flying Car

  1. 1. Advanced Materials Systems Design Developing the Transition ®: Simulation for Composite Structure in a Flying Car With a Perspective from Terrafugia, Inc Robert Harwood, Ph.D Aerospace and Defense Industry Director ANSYS, Inc Robert.harwood@ansys.com 1 © 2011 ANSYS, Inc. February 3, 2014
  2. 2. Innovation and consumer demand are driving the market for autonomous and personalized transport Some recent headlines …………….. ……….. Cars that fly! Street legal, highway capable and fits in a single car garage! Autonomous parcel delivery! 2 © 2011 ANSYS, Inc. February 3, 2014
  3. 3. Performance Requirements, Rising Fuel Costs, Regulation and Competition are Companies to Invest in Lightweight Composite Materials Rising Fuel Cost Reduce weight Environmental Regulation Competition 3 © 2011 ANSYS, Inc. February 3, 2014 Reduce component weight and tooling costs Lightweight composite materials
  4. 4. But the Proliferation of Composite Materials is Challenging Existing Design Processes * Physical prototyping is complex, time consuming and expensive Effective integration of composites into product development requires an understanding of material science, design and manufacturing *S.Riaz, E.S.Greenhalgh, M.S.P.Shaffer, A.Bismarck, "Conference proceeding on Hierarchical carbon fibre reinforced Poly (vinylidine) difluoride composites" ECCM 14, Budapest, Hungary 4 © 2011 ANSYS, Inc. February 3, 2014
  5. 5. Simulation Based Engineering Has an Important Role to Play in the Composite Product Development Process – But It Must Be Efficient When selecting a simulation tool for composite product design, designers should consider whether a tool has: Appropriate failure modes (within layers, delamination, debonding and cracking) Composite layer definition (fabrics, stack ups, sublaminates) Material reference directions for curved structures (draping, fiber angle, correction and flat wrap generation) Critical part identification (failure modes, failed layer and critical load step) Accurate stress failure evaluation (including 3D) Ability to examine through thickness behavior using 3D local sub models where thin shell element approximations are not appropriate Integration with the overall simulation driven product development ecosystem 5 © 2011 ANSYS, Inc. February 3, 2014
  6. 6. Not Only is Efficiency Important, The Increasing Performance Requirements for Composite Materials Mean That Simulations Must Capture “Multifunctional Effects” In this example, an integrated comprehensive multiphysics simulation approach enables the multifunctional performance requirements of an antenna composite radome to be assessed: 6 © 2011 ANSYS, Inc.

  7. 7. Customers are Realizing the Benefit of ANSYS Solutions for Lightweight Composite Material Design Reduce Weight…… The first monocoque designs of the KTM X-Bow were engineered without the use of ANSYS Composite PrepPost. When we did employ the ANSYS software for composites, we were able to reduce the monocoque’s weight – a very important aspect of sports car design – by 20% Click here to read the full story -Dr Martin Perterer CTO KTM Technologies GmbH More Efficient Workflow…… We are using ANSYS software to develop composites that reduce the aircraft weight. Using ANSYS Composite PrepPost within ANSYS Workbench provides accurate results that allow us to reduce modeling time by up to 65% over traditional solid modeling Click here to read the full story 7 © 2011 ANSYS, Inc.
