    Isn's that a B-25 ? ?     
  
Don Maxwell - Oct 22,2004   Viewers  | Reply
    Whoops! Steve, you're right. (I had called it a 24 by mistake--but have changed it now.)     
  
Don Maxwell - Oct 24,2004   Viewers  | Reply
    The first ones didn't.

    They weren't gull wings, this one was just over G'd...?<br /><br />OK Frank, then a hard landing...     
  
Don Maxwell - Oct 24,2004   Viewers  | Reply
    What I've read, Frank, is that the first ones had a constant-dihedral wing on each side. But apparently they were unstable (I'm not sure why), so the production versions retained the dihedral at the root, where I suppose it would have been too hard to take it out, but the outboard sections of the wings were attached with 'no' dihedrehal. (I don't know what the actual angle is.)

    Interesting, Frank, I hadn't thought of that. (Well, I guess the North American engineers didn't, either.) Never having had the chance to fly any of those warbirds (except, briefly, a T-6), I wonder if they all were 'rudder' airplanes, like many of the civillian planes of that era.

    Well it's obvious...lower drag at high mach!     
  
Kenneth Leonard - Oct 26,2004   Viewers  | Reply
    Seriously, wouldn't the sweep adversly affect spin recovery? Of course, so would the wing breaking off...

    Swept wing also improves visibility from the cockpit.     
  
Don Maxwell - Oct 26,2004   Viewers  | Reply
    Thanks for letting me off the hook, Frank. A tapered wing also approximates an eliptical wing, like the Spitifire's, which they say is the most efficient shape.

    I didn't know what Dutch Roll was, but this site helped: <a href="http://www.djaerotech.com/dj_askjd/dj_questions/dutchroll1.html">http://www.djaerotech.com/dj_askjd/dj_questions/dutchroll1.h<br>tml</a>

    I flew a V-tail Bonaza that had that 'tail wagging' thing going on, that must have been due in part to the dutch role tendency.     
  
Chris Vernon-Jarvis - Oct 28,2004   Viewers  | Reply
    Sorry Don,<br />The point of a eliptical wing is not just the taper but also the actual shape of the trailing edge. It is, or at least was in 1935, the recognised minimum drag configuration. The problem is it is also by far the most expensive requiring panels hand shaped in 3D. Hence each spitfire took 80,000 man hours to build, (the equivalent of 1 man life work hours!) One might be surprised there that now we can build wings in composites the tapered wing does not make a come back, however I guess modern wings minimise the difference and since we are not talking about building a plane specifically to win a race that last half percent is not enough incentive.<br /><br />

    This excerpt from the Aerodynamics for Navel Aviators indicates that efficiency of the wing is not the only aspect of interest for wing shapes.<P><img src="inline/20108-stallpatterns_q.jpg" alt="stallpatterns-q"><!-- >'"><br><font color=red size=6>' or &gt; missing in user HTML.

    Dan, I took the liberty of reducing your very interesting stall patterns image to a size that doesn't bust the page margins.     
  
Don Maxwell - Oct 29,2004   Viewers  | Reply
    Dan, I wonder if there's a stall pattern diagram for a wing like the SeaRey's--tapered leading edge with straight trailing edge.<br /><br />Also: While watching a big crow this morning I got to wondering if you can spin a crow. Or, really, if a crow--or any other bird--can spin. Could a crow even stall?     
  
Chris Vernon-Jarvis - Oct 29,2004   Viewers  | Reply
    Dan and Don,<br />That's very interesting, clearly shows why Mr Piper built slab wings, would appear to be obvious choice if you add in the benefit from one size fits all ribs. Perhaps also why eliptical are so out of favour now.     
  
Dan Nickens - Oct 29,2004   Viewers  | Reply
    Crows? I don't know. Who knows how a crow goes? One can only suppose since he’s all dressed in black, from his pointy nose to the tip of his toes. He’s such a stealthy bird wearing colorless clothes. It’d be a good trick to measure his angle of attack. With such variable airfoils I’ll bet the air always flows.<br /><br />The SeaRey airfoil is easier. PA’s Eduarod says the wing stalls from the ailerons in. Only the cuff on the leading edge keeps us from stalling like a Spit.<br />     
  
Don Maxwell - Oct 29,2004   Viewers  | Reply
    If Eduardo's right, Dan, (and he probaby is) where does a stall begin on a DC-3? There's no leading edge extension on a DC-3. Is there root-to-tip washout instead?     
  
Jim Thomas - Oct 30,2004   Viewers  | Reply
    Dan, nice rhymes... <br /><br />Don, I don't know much about DC-3's but I have a complete operator's manual for the one from the Museum of the Ozarks (I think) where one can go and earn a type rating. If you'd like to look at it, I can zip it up and put it on a CD for you. We're in the middle of Hurricane damage control and a home refi, so it may be awhile, but...     
  
Don Maxwell - Oct 30,2004   Viewers  | Reply
    James (Jim?), wow--the DC-3 POH !!! I'm not likely to get to fly one, but it sure would be interesting to look at the manual! But I've had some personal experience with hurricane damage control--so please don't feel obligated.<br /><br />The only time I've ever thrown up in an airplane was in a DC-3, in a thunderstorm while returning to Ft. Gordon, GA, at the end of a three-day pass that began with an all-night drive to Reading, PA, in a car with a broken power steering belt. (Long story.) But a couple of years later I got to shove boxes out the door of a C-47 to resupply radar installations on rocky islands off the coast of Korea. That more than made up for barfing into a paper bag. (Especially when one box went through a mess hall roof.)
