I'm building up a long thin KFm3 but want a Hoerner curved tip. Any thoughts on how to step this down with the KFm3? The dimensions are 12 foot span by 13 inch cord. Input would be appreciated. If the wing tip is cut at 45-degrees with a small…

For those of you interested in the Kline Fogleman airfoil concept, you might want to check out this thread which discusses why people chose the airfoil they use. It is only four pages long and a number of people seem to prefer the KFm airfoils and…

Looks fantastic. I want one. Please publish build pictures!

It is a similar layering that makes some other foam flying wings and deltas rigid enough. an example of such construct, though not a KF airfoil, is the Pibros delta using decreasing triangle layers in a folded foam sheet envelope.

Unlike the example from above the KFm3 airfoil of my flying wing is built without spars (except for the root section). The rigidity results from the overlapping foam sheets. Have a look at the PDF plan for a cross-section of the wing.

Interesting reading. I followed the links to rcpowers.com, and greatly enjoyed the interview with Dick Kline (the 'K' in KF). The interview is in 4 consecutive YouTube clips starting about 25% down the page…

Right (I was referring to 'The Study" which I think is a spreadsheet of subjective observations. Certainly a world in which "5" means "As fast as the other planes" doesn't come across as the most scientific. That…

I might be missing something. The base version of Labview is $1,299 (The Mac version is $2,600). Is there an academic or personal-use version that is less expensive?

bGatta, Way to bring the conversation back around to autopilots, since that is what this site is for! I was a little off-topic in posting this, but I found the KF airfoils pretty interesting because they look like a pretty quick and easy way to…

I found the linked article interesting, but merely subjective - and note that an autopilot may be an excellent tool for evaluating wings empirically, since the results can be directly reduced to numbers. This would requite a ground link or…

You may also check out this study by Rich Thompson Or the RCgroup thread There's also a nice test video of 4 different KF airfoils on youtube (by RCpowers.com)

Kline-Fogelman Airfoils

One of the members posted a new design flying wing today and mentioned it had the Kline-Fogleman airfoil. I did some research on this unique airfoil and came up with this.Here is a short article about the design: http://bfoamy.com/?page_id=664And here is a few variations of the design, presented as airfoil sections:See More

Can you elaborate on the design and build process? Did you use software and if so what kind. Any information about this process would be wonderful. Thanks.

Funny, I just posted about this - how to scratch design/build a Global Hawk. I think the Global Hawk would be a fantastic project. Maybe we could divide the work. Put a 70mm EDF unit on there, and some serious avionics, cameras, etc. NICE
