Pietenpol-List: Streamline plastic fairings

Post by matronics »

Original Posted By: Gerry Holland
There used to be an extruded plastic streamline tubing material that was made toslide over round tubing and the ultralight guys used it for this very purpose.I acquired some a number of years ago and it was test-flown on the prototypeFlying Squirrel, where it proved to be of some benefit in drag reduction andcruise. I'll try to find out where I got it, but I want to say that it wasthrough Carlson or Sky-Tek.Slipping some plastic extrusions over your round tubing struts and then securingit in place is just about as simple and inexpensive as you're going to get.--------Oscar ZunigaMedford, ORAir Camper NX41CC "Scout"A75 powerRead this topic online here:http://forums.matronics.com/viewtopic.p ... ___Subject: Pietenpol-List: Streamline plastic fairings

Hi.Some information at:http://www.uflyit.com/streamline_fairin ... ings.htmlI used these fairings on my cabanes and U/C legs.Just slit them around trail edge with a Xacto type knife and slid over, fixingwith small aluminium brackets.In truth not sure how much it improve things as the aircraft was well beyond abrick aerodynamically regarding parasite drag.Made me feel better!RegardsGerry________________________________________________________________________________

Gerry=3BYes=2C that is exactly the stuff. Extruded plastic sleeves that slip on over round tubing. The Flying Squirrel has two sizes of wing strut tubing=2C main and drag=2C so there are four struts and they are roughly the same length as the ones on the Piet. In testing=2C the prototype picked up 5-7 MPH in top speed after adding the streamline sleeves over the round 4130 steel struts. That seems to agree with the claims made on the ultralight websites that you provided links to.Oscar ZunigaMedford=2C ORAir Camper NX41CC "Scout"A75 power ________________________________________________________________________________
