The March 2009 design class was the most fun ever. On the left, M. Hollmann. Then, Ralf Twellmann from Germany who has built one of the best KIS airplanes which has been on the cover of a number of magazines. Hollmann did the stress analysis on the KIS for Richard Trickle. Nathan Gall, an aeronautical engineering studen from Florida who talked his dad into coming to the class. Schuyler Greenawalt from Aero Crafters in Watsonville, CA. David Gall. David graduated from FTU just as Hollmann did and had the same thesis advisor, Prof. Henry Hagedoorn. Last, Aaron Burhoe who is building a G200 which Hollmann designed. Aaron noted some differences between the kit and the original plans. This class was a blast! We all had fun and learned something too.

The International, October 2008 Design Class: from left, M. Hollmann, (Germany), Mike Butulia (USA), Souleymane Sall (S. Africa), Mike Bauer (Alaska) and Oliver Garrow (France). Great group of aircraft designers.

The 2008 Aircraft Design using FEA Workshop was attended by Jan Satraneck, M. Hollmann, Nicolas Carona and Michael Hasz. This is a comprehensive and difficult topic but everyone agreed that we covered much in 2 days.

The March 2007 FEA class with attendees shown on the left was one of the most fun classes ever. In front, left; Hoon Chung, Tamir Lance. Back row; Hollmann, Art Thompson, Kent Koester and Noah Oliver.
My name is Noah and I recently attended the FEA class over this last weekend. I wish to extend my most exuberant appreciation for an extraordinarily enlightening weekend. The amount of material I've been able to consume/teach myself over the last several months pales in comparison to that which took away from Martin's FEA class. The combination of the class material and Martin's tangential tellings of a life time of aeronautical design was more valuable than any book I've read on the subject so far.
Thanks again to you all and all of those who took the class with me.
Look forward to the flutter class.
Hi Martin -

Thanks for that great workshop and such a good collection of enthusiasts to share it with. Now you have put me back on the path of aeronautics which I started so long ago. I'm a candidate for the flutter course and hope to see you for that.- Kent

Just a quick note to say how much I enjoyed the class this past weekend.  I also appreciate you enduring my questions regarding all manner of other design issues - Monty Python was famous for quipping "No one expects the Spanish Inquisition", and at times it must have felt like you were under similar scrutiny. One final note - I watched your "30 years at ADI" video yesterday evening - what a wonderful biography and compendium of your body of work!  Not to get too gushy on you, but you really are an inspiration.
Thanks again for a great "class" - Mark

Hi Martin -Wanted to drop you a quick note to say how informative and enjoyable your class was this past weekend.  During the class, I was concerned that we hadn't gone in enough depth on non-FEA topics, but having read through most of the first volume of "Modern Aircraft Design" over the last two days, I agree you hit just the right balance ... your book is so well written, and is so self-explanatory, that any reader could pick up those concepts and work those formulas on their own ... I doubt the FEA work would lend itself to a similar self-paced approach, so spending more time on FEA in class turned out to be entirely appropriate.  My one suggestion might be to include Volume One as an additional "handout" for this class, even if it means bumping the cost of the class to $650 ... no one who is serious about aircraft design should be without that book. And I was flattered to see the picture of our class on your website, with the caption: "One of the best classes ever" - it was a very good group,
indeed. I'm thinking of attending your Composite Workshop on May 27th/28th, and wanted to confirm that a) you are still planning on holding it (that is Memorial Day weekend, after all), and b) whether there was still room in the class should I wish to attend. Best Regards, - Mark

The Flutter Class was attended by four serious engineers. For Sunday lunch, we ate sandwiches on my sailboat and took a tour of the Monterey Harbor. After going over the SAF program we needed this break.

Dear Martin, I really enjoyed the flutter class, and found that it suited my requirements perfectly. I came away with a much better idea of the fundamentals without the distraction of concentrating too much on raw theory. I would recommend the course to busy engineers.
Thank you for an enjoyable weekend.

Hi Martin, I've really enjoyed both classes and you opened my mind with the capabilities of both NISA and SAF software. I've been playing with the evaluation copy of NISA a lot. I have managed to easily import a shape of a wing from a CAD software, mesh it with composite shell elements and so on. The preprocessor is very powerful. I discovered how to run element verification to see if the aspect ratio and normal are correct for each element. I'm coming to the next composite class for sure. Thank you, Laviniu Tirce

Comments from attendees:
Hey Martin! I wanted to thank you for putting up an awesome class in March. Even with some experience with composites for a few years, I still learned a great deal of techniques offered.
Thanks! Peter

Hello Martin, Thanks for a great seminar, I really enjoyed it! And I really enjoyed looking at your flying sculpture, the Stallion! I hope I get to do your flutter class in the near future, (although I'd rather get a ride in the big red, white and gray bird). You're a very good speaker and thanks again for a very informative and interesting class!
Dan

Martin,  just wanted to thank you for hosting and teaching such a good course on FEA, and also thank you for the demo ride in the Stallion.  It was fun to chat with you about your experiences.  I appreciate your openness and willingness to teach us and answer questions, for you are truly living the dream. Thanks for everything, and drop me a note if you are ever make it to the Dallas area!

The FAA Flutter Class being held in Oklahoma City, Oklahoma in the Summer of 2002.

Since then Hollmann has been working as an FAA  DER for design, analysis and flutter on a number of STCs Projects for Flutter and Propeller Whirl Mode.
