Hello All!
I'm a newbie! Glad I found this forum. It is really cool! I have learned a lot already.
I am in the preliminary design stages for a tractor style, tail dragger Autogyro. At this point I am still trying to decide on materials.
I definitely want to use aluminum tubing (6061-T6), because of high strength to weight ratio. Aluminum tubing with gussets and CherryQ rivets should make a very strong airframe. However, I am undecided about the covering. I know that the AL skin will be heavier, but it should make the airframe even stronger, and I would not have to paint it, if I didn't want to. Also, I am comfortable working with sheet metal, and there is something reassuring about having that metal skin around you.
However, I do not want want to dismiss the possible use of a Fabric Covering System, such as PolyFiber or Hipec. The major advantage would be weight, and, possibly speed of build. There may be many other advantages, too, that I am unaware of.
I would appreciate any input on a comparison of the the two: AL skin -vs-Fabric.
What are the disadvantages of Fabric?
Thanks!!
