About this Plan
Termica. Free flight glider model. Wingspan 1.4 m.
Direct submission to Outerzone.
Quote: "This is another design from Shigemi Morimoto when he was at Aerobras, it's a free flight glider, Cheers M Franco"
Update 15/11/2022: Added airfoil dat zipfile, thanks to Martin Huebner.
Quote: "Dear Steve and Mary, I appreciate our cooperation very much. Please find attached the airfoil coordinates for Termica (oz13478). I took the contours of the airfoils from the vector plan and saved the coordinates in standard Selig format.
For further calculations, e.g. with xfoil or xflr5, I smoothed the coordinates because the contours weren't exact enough. It would be very nice if you could add the file to plan page. Greetings from Germany,"

Corrections?
Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

What a superb, elegant shape! Another one to persuade you from trout angling to thermal hunting, or laying back on a gentle slope :-)Fine, competent modern redraw work, I remember seeing Aerobrás ads in old Donald Duck mags, Brazillian edition. A Benção, mestre Franco :-)

Hello all. Such a nice glider! Does anybody know, when it was designed?
By the way... Steve, thank you so much for your great work!

Hello - greetings from the frozen once more Yukon.
The Termica drawing shows a 6cm and 11cm height for the dihedral and polyhedral. Using the 11cm figure as correct the 6cm figure will generate an almost straight wing - basically the drawing and the dimensioning are not in agreement. By scaling the two dimensions you can generate a ratio that is determined by the drawing - this will give a 3.4332 plus cm to replace the 6cm figure given.
What the designer/drafter had in mind is unknown - I used 3.5 cm to generate a decided bend at the joint but 3cm is probably just as good or maybe better.

I think that the likelihood is that the inner panel is lifted to 6cm at the dihedral break, laid down flat on the board and then an additional 11cm of dihedral added to the tip section with the inner panel flat on the board. 6cm is only 2 1/3”, 11cm is 4 1/3”. Combining those dimensions would put the wingtips 6 2/3” off the board, which would seem reasonable for a 55” span free flight glider. 4 1/3” seems a bit marginal and doesn’t reflect the proportions of the front elevation of the wing shown on the plan. I suspect that it’s an annotation issue as opposed to a drawing problem.

Curious. I agree with KW, the polyhedral drawing is unclear, and the 6 and 11 cannot both be true. So I tried taking that part of the drawing and scaling it up to full size. For me, that shows the wingtips at 10.67 cm height. The lower break seems to be 3.34 cm. I agree with Pete that that seems quite shallow in total.

Dear sir, Here is the Termica under construction plan [pics 003, 004] increased to 145% for Radio Control. Cheers,

Notes
* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
Scaling
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
