Iam sorry, I didn't make myself clear. The design airfoil is a 4412. The MAC is 42" and the AC [ Aerodynamic Center] some times called the neutral point is about 25% of the a MAC. Sweping the wing forward 3-5 degrees would move the AC forward. I know the aircraft CG should be forward of the AC...
I want to thank all how critique my design. But gentlemen Iam not trying to design a jet aircraft only a light sport aircraft weighting no more then 850 lb. GW. If I am reading it right, I should try to have the wing airfoil AC close to the aircraft CG. but not ahead of it. I would appreciate...
The benefit of this shoulder wing design is the pilot sit forward of the leading edge of the wing and has greater visibility all around. That is want Iam looking for in this design.
This is design idea have had for a number of years. The aircraft I vision would be a single seat,shoulder wing, all metal aircraft with VW engine light sport aircraft.
One of the problems I am having is the wing. Most light planes with a shoulder wing have there wings swepted forward a few...
Are there anybody building a BD-6 out there? I have been to the Bede web page on the net. They don't have much information on the BD-6. I was just wondering do you think it can be built as a light sport aircraft. It will need a new wing. I don't think wing area 55.5 sg/ft. is going to do it. I...
I used to own a 46 luscombe 8A and one day when landing I got bit by the old Luscombe ground loop and ended upside down. The old girl didn't look so good now. After I got over feeling like an ass. I started rebuilding some parts. The first was the ease the vertical tail. Removing the damaged...
Thanks Orion for your reply. I have another question. In L. Pazmanys book "Light Airplane Design" I think I read to try to keep the aircraft C/G Between 15% and 30% of the MAC. The maximum forward C/G would be the aircraft at it's lightest weight, light pilot and low on fuel and the maximum Aft...
The Swiss Colibri MB2 is a wood design with a VW engine. I would like to make a all metal version of the aircraft. The empty weight of the wood Colibri is about 390 lbs, wing span 20 ft with 89 sqft wing area, lenght 15 ft. My Question is , is it possible to build an all metal Colibri and keep...
Hello to All,
Iam new to this list, but I am not a new homebuilder. I have built two Midget Mustangs and started a third. But like many aircraft homebuilders I would like to build my own design. Iam at the age now where I don't care to carry passengers. I what a single seat A/C. I don't care...
