PS: In my previous post, I was just telling you what the engineer said, I am in
no way telling anyone to change wing planform or saying it is better than what
we have.
When changing things dramatically in a design like the KR2, one is stepping out
into new territory possibly. As these planes are
My Dallas EAA chapter had a NASA engineer talk to us at least 20 years ago. His
statement was if your airplane design was such that you could not go well over
200 mph that a tapered wing would not help you as far as speed. He said the
most drag in piston driven aircraft was in the engine cooling
There's an article that appears to cover all angles of the rectangular wing
at
http://www.flyingmag.com/article.asp?section_id=12&article_id=170 . Make
sure you read all three pages. I put "rectangular wing" into Google and
this was the one on top...probably for good reason. Peter Garrison w
Sid,
What formulas or table did you use for calculating the change in flight
characteristics for a rectangular planform wing? The 20% figures you state
seem a little extreme. Also, I think the change would add only about 7 Sq ft
to the wing area.

Hm. The KR1B Motorglider numbers that Virge cited of 484 empty weight
and 27' wing span yield .66, which is higher than .62. I guess if you want

I am designing (stealing ideas) for a plane using KR construction that
would fit within the Sport Pilot rules. It will be single place, Hershey

it will be VFR with only basic gauges and probably open cockpit to begin
with. I
I researched this issue before giving up in disgust with the FAA on Medical
issues. I think the wing needs to be 10 feet long (outer panels, and that
you should have zero twist. The out half of the outer panel should be a
slotted airfoil, and the elevator/stabilizer ought to be enlarged to power

Virg, I respectfully mention the above comment may be jumping the gun.
First of all, there is not much history out there on the motor glider.
Second of all, I would seriously recommend one go to the actually d

The KR1B motorglider may not be such a bad idea after all. Maybe not for
