787Guy Posted October 29, 2014 Share Posted October 29, 2014 Would it be permissible to use an under wing L shaped pitot tube instead of having one on the nose ? Seems it would be less likely to get damaged and also easier to heat it without fear of melting the aircraft. Quote Link to comment Share on other sites More sharing options...

Marc Zeitlin Posted October 30, 2014 Share Posted October 30, 2014 Long EZYes. Might be a bit harder to calibrate, depending upon where you mount it, but it's been done before successfully (the one that I know of is a Berkut with a BRS parachute that I designed the install for). The calibration was pretty good. Quote Marc J. Zeitlin Burnside Aerospace marc_zeitlin@alum.mit.edu www.cozybuilders.org copyright © 2024 Link to comment Share on other sites More sharing options...

Marc Zeitlin Posted October 30, 2014 Share Posted October 30, 2014 Berkut with BRS ? Did they have to give up the rear seat for that ? Yup. Single seater with a bunch of baggage space at this point.

Kent Ashton Posted October 31, 2014 Share Posted October 31, 2014 You will get different opinions but I don't think you want to fly a canard airplane in ice, so a heated pitot is unnecessary. On a regular airplane as the wings ice up, I would say it is a more gradual process as you lose lift from the effect on the wing airfoil and weight of ice. Also on a regular airplane, when the horizontal stab ices up, the weight of the ice tends to add to the downward force that a stab normally develops so the airplane can keep flying until overcome by the weight of ice and airfoil effects. When a canard airplane ices up and a canard loses lift, the airplane is going down even though the wings could support their load if the deck angle could be maintained. There have been some exciting stories over the years of guys who flew into heavy bug swarms and had to land very fast due to the loss of canard lift. When I have flown in rain, the pitot instruments sometimes get squirrely but I just set the power and ignore them.
