Does anyone have a good source for information and possibly drawings of the original Helio or Storch wings and the placement of their slats. I would also be interested in looking at some original examples of these airplanes and others which employ slats  or slots if anyone knows where one might be found. I can be emailed direct at  mike_obrien@raytheon.com 

If you have pictures or information on any plane that uses these features....homebuilt or otherwise, perhaps a personal project or even a museum showpiece, technical data, or even a story about planes using these features........I'd love to see it.

Also, if you would like to comment on the use of any STOL related technology, personal experience, likes/dislikes please feel free to give your opinion.

Mike,

Over the past dozen years I have been teaching in an EMBA program in Bucharest. Hanging In the Romanian military aviation museum is a replica of Henri Coanda's 1910 monoplane which shows the earliest example of a slotted wing. (The main airport for Bucharest at Otopeni is now named for Coanda. He was a polytech graduate who worked in France and Romania, and , I believe, taught at the Polytech in Bucharest until the 1970's). I have pictures and a brochure of Coanda's plane from my several visits to the museum., as well as a web link to his work (He's known for the "Coanda Effect").

I have a Zenair CH701 STOL based at KTAN with 200+ hours "low and slow"..including two cross-countries KTAN-KOSH. The CH701 is radical...take off is less than 100ft,...one of the only planes that can take-off from anything it can land on. Super Cub and Maule drivers weep at the sight!

Regards,

Ted Jula

p.s KTAN open house is 19 June. If you're with Raytheon in the Boston area, you're welcome at Bldg 27, Tailwinds Hangar #23..

Mike,

slats and automatic slats have been used on a number of STOL planes, as well as on faster aircraft for high angle of attack operation during T/O or ldg.I guess the inventor of the slats was Geoffrey DeHavilland. You will find slats on some of his designs. The most famous aircraft of course is the Fi 156 Storch, but also the post war Dornier Do 27 uses fix slats. Automatic slats have been used e.g. on the famous Messerschmitt Bf-108 4-seat touring aircraft at the aileron section of the wing, the same on the fighter Messerschmitt BF-109. The French post war Morane MS 880, 892, .... series and their Polish derivative Koliber use automatic slat ranging almost over the full spanwidth.

Hello,

Consolidated Vultee L-13 circa 1946 had fixed slats, deep chord wings and fowler flaps. I have a project I'm working on. It; being equipped with an R-985 would supposedly get off the ground in three rolls of the tires.
