To match the lift distribution over the wing with weight distribution over the wing. Most aircraft have all their weight in the centre (eg. fuselage). The ideal match is actually an eliptical shaped wing planform but tapering is easier to build and is a good compromise. If a plank flying wing

Mooneys don't have forward swept wings, they have forward swept trailing edges on the main wing and the horizontal tail and both have straight leading edges , except the Mooneys inboard first 3 feet are tapered rearward, then outboard of that they are straight perpendicular to the fuselage

KR> FORWARD SWEEP OR CONSTANT CHORD WING

I talked to a hot shot NASA Aeronautical Engineer some years back who had been involved heavily in studying and testing different wing shapes on real airplanes. He said if your airplane design would not exceed 250 miles per hour that tapering a wing might look cool but it gained you absolutely

Hope nobody minds my 2 cents. Military speaking swept wing aircraft normally will not change wing position until higher speeds are attained. This is where maximum advantage is attained. The advantage at lower speeds is negligible for the expense. However I am not familiar with low speed

Forgot to mention... the H/S is complete (glassed) and 6" wider than plans... can I use this with the new airfoil, or do I need to think about modifying this too? Thanks again. Mark W. -Original Message- From: krnet-boun...@mylist.net [mailto:krnet-boun...@mylist.net] On Behalf Of Mark

KR> New air foil conversion from completed RAF airfoil spars

I acquired a project (KR2S) that is about 40 - 50% complete; boat, spars, tail feathers etc. that was originally built to the plan's wing configuration. I would like to use the "new" airfoil and know that the spars need to be "taller". What do you think is the best approach to doing this? The

KR> Wing sweep question.

Hi Larry I think Pete is saying the 25% chord line is swept forward slightly as it progresses outwards NOT the leading edge of the wing. The former being determined by the ratio of the leading edge angle to the trailing edge angle where the latter is proportionately greater. Nonetheless it is an

I have a model airplane that has about 10 degrees of forward sweep. Flies normally. However the wing is extremely stiff and will still flutter at high speed (150mph) if the ailerons have any slop in them. On 7/12/10, zorc...@aol.com wrote: > Then I guess every Mooney out there

I'll put my two cents on this; Perhaps if we were talking 15 or 20 degrees of forward sweep you guys would be correct, but I would like to point out that there have been several sailplanes with forward sweep, the "Genesis" is one and Jim Marske has designed several too. they have less than 5

On a more basic note, I will add two things about forward sweep. 1. Your wings must be much stronger to handle the forces caused by the negative stability. 2. It generally requires a computer controlled flight system to handle the bending moments.  Not recommended.  Hal Dantone --- On Mon,

I don't remember the exact reason, but I read in a Raymer aircraft design book that any kind of forward sweep was a bad idea on general aviation aircraft, for various reasons including stability and stall characteristics. We're talking forward sweep though, not just "no" sweep. Below is

KR> KR2S Wing sweep question.

For a straight wing tapering from 48 to 36 inches; when quarter chord sweep is straight, the leading edge of the tip spar is 3 inches behind the leading edge of the root spar. It does not matter where the actual wing spar is located and what angle it has. ( but I believe on the KR it should be

I was surprised when I saw it, as I'd always assumed that there was no sweep at all. As it turns out it's next to nothing but the spar is indeed straight, but the sweep at 25% chord is just a tad under 1° forward. When you look at the wing, the trailing edge tapers forward more than the

KR> Mains possition

Hi Barry I'm no aeronautical engineer but it seems to me you need to get more weight forward of the CoG and this is not achieved by moving the wheels. Once the wheels have left the ground their position becomes irrelevant and if you can't get the tail up with forward stick at that point then it

I was working with the CAD drawings I've done in Rhino for the KR2S and I noticed that the outer wing according to plans has a minute amount of forward sweep. I wonder if this has anything to do with the very sensitive aft CG issues the plane experiences? Can anyone else confirm or debunk this
