(Steven Dortch) ________________________________ Message 1 _____________________________________ Time: 08:25:48 AM PST US Subject: Pietenpol-List: Multiple structures in the wind. From: Steven Dortch Gentlemen, I have access to a buddy who is an aerodynamacist and pilot and plane owner. He works at a well known boating school in Maryland. I asked him about placing antennas and told him that AFTER I had my plane up and flying I was looking for some aerodynamic cleanup and he todl me the following. First, the antenna must be placed first for reception and transmission and then for aerodynamics. Near metal cabanes or struts makes the radio very directional. He had to look up what a Pietenpol Aircamper looks like. His "Comments: Solid wheel instead of the wire spokes are much better. On bungee covers, don't use canvas, use plastic/fiberglass fairings. A flag (canvas) in the wind has lots of drag. A canvas front cockpit cover will help but think about making one out of lightweight fiberglass and make it fit well. Yes, to put fairings on the round tubes. Actually draw a real airfoil, e.g., an NACA 0012 or 009 if it will fit. You can find the coordinates in NACA Technical Report 824 or in a book by Abbot and von Doenhoff or I can scan and send them to you. Fiberglass or foam with a thin fiberglass cover would work. If you are good at sheet metal work, then thin aluminum will also work. Look in the marine field for fairings. I have seen fairings on sailboat shrouds, etc. A friend at the airport has a Piet. I'll have to go look at his and see what he has done." Any Any other ides from the peanut gallery. we should be careful, we don't want to exceed VNE in cruse. -- Blue Skies, Steve D ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message pietenpol-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/Pietenpol-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/pietenpol-list Browse Digests http://www.matronics.com/digest/pietenpol-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
