Intelligent Light and FieldView

Next Generation Transport Aircraft Workshop 2016

NGTransportAircraftWorkshop16 次世代航空機ワークショップ

I was grateful to be invited to participate and represent Intelligent Light at the Next Generation Transport Aircraft Workshop held in February, 2016 in Hawaii. The conference brought together leaders from industry and universities in Japan and the United States who are working to develop transport aircraft of the future.

Major tracks of presentation and discussion were:

  • CFD methodologies and applications
  • High order numerical methods in CFD
  • Uncertainty Quantification (UQ) and optimization
  • Data assimilation
  • Carbon Fiber Reinforced Polymer (CFRP) Laminates
  • Failure modes for composite structures
  • 3D printing of continuous carbon fiber reinforced plastics

I found Dr. John C. Halpin’s (JCH Consultants, Inc.) keynote presentation “The Aging Composite Airframe” to be a fascinating discussion and a great start to the meetings. Dr. Halpin asks the question: How long should a composite airframe last? While non-composite aircraft have an estimated service life of 35-40 years, carbon fiber plastics service life is estimated at around 20 years. Experience shows delamination based on power load and Mode 1 simulations are commonly run while Modes 2 and 3 are infrequently run due to the computation cost of these simulations. Accurate simulations are needed to develop appropriate safety standards for these aircraft.

Intriguing too was the use of SPH for bird strike simulations described in Shigeki Yashiro’s (Shizuoka Univ. Japan) presentation "Numerical analysis of bird strike on CFRP laminates using smoothed particle hydrodynamics in a generalized coordinate system". SPH handles the deformation well but is not suitable for representing microscopic damage as the particles are uniformly distributed. Dr. Yashiro modified his code to handle arbitrarily defined spacing of particles to produce credible results for this microscopic damage.

It is clear that some very interesting work is being done in the universities to develop methods and tools to address the challenges of working with composite materials. Further, the range of configurations and operating conditions will require probabilistic evaluation and uncertainty quantification (UQ) to develop safety standards and design targets for heavy lift aircraft. While the researchers are developing methods, industry is developing repeatable and reliable production workflows with mature tools and technology. Industry leaders are eager to speed development and increase accuracy using new methods and workflows that are proven and reduce program risks.

I wish to express my gratitude to the organizers for their kind invitation. I was pleased to contribute to and learn from the discussions with my colleagues.

次世代航空機ワークショップ

2016年2月にハワイで開催された次世代航空機ワークショップにIntelligent Light(弊社)の代表として参加させて頂きました。このワークショップでは日米の次世代航空機の研究開発を行っている企業及び大学が集まり、研究発表や意見交換が行われました。

主なトピックは以下の通りです。

  • CFD手法及び適用
  • 高次精度CFD
  • 不確かさの定量的評価、最適化
  • データ同化
  • CFRP
  • 複合材料の破壊モード解析
  • 複合材料の3次元プリント

その中でもDr. John C. Halpinによるキーノート発表「The Aging Composite Airframe」はとても興味深い発表でした。発表の中で、Halpin博士は複合材料で航空機を設計する際に、そもそも複合材料で作る航空機フレームは何年持つべきなのかと問いかけていました。現在の金属製の航空機は約35年から40年の寿命を設定して作られている一方、現行の複合材料の寿命は約20年 と言われているそうです。現在複合材料の剥離解析は第1モードのみで行われており、計算コストの高い第2第3モードは考慮されていない事が多いそうです。 より正確な多モード解析を行うことによって、より正確な材料の劣化予測が出来るようになり、安全な材料の開発につながるそうです。

また静岡大学の矢代先生らによるSmoothed Particle Hydrodynamics(SPH)法を用いたバードストライクによる剥離解析研究も興味深いものでした。SPH法 はシミュレーションに格子を用いない粒子法のシミュレーション手法の一つです。格子を使用しないので、層剥離や変形を容易に取り扱う事が出来るという利点 がありますが、粒子を均等に配置する必要があるので粒子サイズ以下の小さいサイズのダメージを取り扱うのが難しいという問題があるそうです。そこで、粒子 間隔を任意に設定出来るようにする事により粒子サイズ以下のダメージを表せる新しいアルゴリズムを開発されたそうです。

本ワークショップにて次世代航空機の開発に 向けた様々な研究を学ぶことができました。上記の研究以外にも安全基準の策定のための不確定性の定量評価等も盛んに行われている様です。大学では革新的な 手法の開発、一方企業での研究では開発スピードの向上と同時にリスク低減に向けたより精度の高いワークフローの開発に重点が置かれ、より実用的な研究が行われていると感じました。

本ワークショップに参加させて頂いた事に感謝の意を示すと共に、このような会に参加させて頂いた事を光栄に思います。

Authors Book Signing Event at AIAA SciTech: Aerodynamics Textbook Introduces Undergraduates to CFD

At this year's AIAA SciTech, Intelligent Light hosted a special community event around the recently published undergraduate level textbook "Applied Computational Aerodynamics: A Modern Engineering Approach". Authors David R. McDaniel, Russell M. Cummings and Scott A. Morton, joined us during the exhibit hall opening reception for lively conversation and to signed copies of their book for other educators, students and aerospace professionals.

Many people purchased the book from Cambridge University Press both in the exhibit hall and brought it to our booth to be signed by the gracious authors.

Intelligent Light contributed to the development of the visualization components of the text and FieldView images are used throughout. Further, students are encouraged to explore sample datasets interactively using the FieldView Demo Version.

The FieldView Demo Version is useful for educators because it allows students to become familiar with the same commercial software they are likely to use later in their CFD careers and because it is free to download and requires no license.

We'd like to thank the authors for their leadership in developing the next generation engineers for the aerospace industry. We thank them for their time and generosity in meeting with people and making this a great event.

Formula 1 & FieldView – Winning CFD Workflows

Hear it for yourself!  

LIVE Webinar Tuesday, December 1, 2015 - Register now!

Torbjörn Larsson, Creo Dynamics AB, has an impressive background in aerodynamics and CFD methodology. His track record in Formula 1, most recently at Ferrari, establishes him as a preeminent CFD workflow engineer. He has been instrumental in building up the CFD department for the Sauber F1 team and has since led the CFD teams at Sauber, BMW and Ferrari to much success in Formula 1.


Mr.Larsson presented Formula 1 workflows designed with FieldView to a group of over 100 CFD engineers at the 2015 VINAS User's Group Meeting in Shinegawa, Japan. This international audience included CFD engineers from Motorsport, Automotive Manufacturing, Heavy Industry, Government Research Agencies and Academia.

"Presenting at the VINAS UGM in Japan was an amazing experience. Japan is synonymous with both excellence in engineering and a passion for motorsports. More knowledgeable listeners are hard to find," said Mr. Larsson. "Being able to showcase to this audience how the ultra-fast CFD workflow seen in Formula One has gained further efficiency from the integration of recent FieldView XDB technology was truly inspiring and rewarding."

F1 teams are among our most demanding customers due to the need to simultaneously achieve breakthrough results in a very short time while building a robust, reliable production workflow.

Formula 1 teams demand:

  • The ability to manage huge volumes of results data in very short timeframes
  • Ongoing acceleration of their entire CFD workflow
  • Delivery of vital engineering information to the right people in the team, on time, every day.

Mr. Larsson's presentation focused on designing workflows to meet the demands of Formula 1 CFD teams where huge volumes of data and very short timeframes require innovative and robust automation. His solution includes the use FieldView XDB extracts as a way to reduce data size and achieve required throughput.​

Mr. Larsson is a fluid dynamics and CFD methodology engineering consultant at Creo Dynamics AB, helping organizations improve the efficiency of their CFD operations.
