Pietenpol-List: Aircraft drag

[matronics]

Original Posted By: "Steve Ruse"
I wonder if anyone has ever considered using a V-type construction on the wing struts and doing away with the X-bracing of the wires. I am purchasing a set of Taylorcraft wing struts from a friend of mine who had to replace his because of some AD. He has punched the old struts and found that they are fine. I don't see why with the proper attachment to the fuselage that V struts wouldn't work on a Piet. Anyone who knows different, let me know.----- Original Message -----

How about steel tube landing gear struts. Did he streamline them also or did he use wood?----- Original Message -----

You cannot do away with the x-bracing, but you can certainly use those T-craftstruts!GarySent on the Sprint Now Network from my BlackBerry-----Original Message-----

Careful Charles, you'll draw the wrath of the 'stick to the plans' crowd if you'renot careful - deviance shall be punished! :)And a Merry Christmas to everyone, too !Kip GardnerOn Dec 23, 2010, at 1:34 PM, Charles Campbell wrote:> > I wonder if anyone has ever considered using a V-type construction on the wingstruts and doing away with the X-bracing of the wires.

Yeah! I'll probably stick to the plans. Except after viewing that video I'll probably streamline my gear legs. Use some balsa and light fibreglass should do it.----- Original Message -----

Charles,You can build it any way you like...........but if you use those "V" struts, you will be forbidden from calling it a Pietenpol. Also, keep in mind, if you show up at Brodhead, you will be banished to the far side of the airport, where the spam cans park.Dan HelsperPoplar Grove, IL. -----Original Message-----

The old recording of the effects of different profiles on drag wasinteresting, but, remember, drag is a function of velocity, too. Theexamples shown were at 210 mph. Before anyone spends undue time, effort andexpense on streamlining their steel landing gear, flying wires, etc, youmight consider that you will very seldom be flying any faster than 1/3 thespeed of the demonstration. I seriously doubt if it's worth the effort.Gary Boothe________________________________________________________________________________Date: Thu, 23 Dec 2010 17:30:22 -0800 (PST)

Yeah, I thought of that, too. Wish someone would do a similar test at 85 MPH. Wonder how that would come out?----- Original Message -----

OK! OK! I give. Two struts it is with cross wires -- just like the plans say to do it! ----- Original Message -----

A lot of the drag on the piet comes from the cables. A round 1/8in cable has moredrag than a 1.25 x 3in streamlined strut. I think drag reduction on a pietis futile as long as you have all those cables.Doug DeverIn beautiful Stow OhioDate: Thu, 23 Dec 2010 19:41:54 -0700Subject: Re: Pietenpol-List: Aircraft drag
