    Aileron Design - What works and why?

    Get some soaring time, and all your 'yaw in turning' blues will go away with now instinctive rudder input. Those tufts will do wonders for learning the difference between a 'skid' and a 'carved' turn.

    German P-51????

    Corky Meyer is a highly respected pilot whose opinions deserve respect. I had an opportunity to talk to him just after he published his book - at Oshkosh circa 2007? Because of the high investment and maintenance costs of Warbirds, nobody (including Meyer) pushed either the P-51D or P-47D that...

    German P-51????

    Respectfully - the availability of C3 was always there for Rechlin Test operations and the 51B when captured was using 130. The P-51B 'light' at 61 in. MP was delivering 445mph in May 1943 test flights - as well as 4100fpm ROC down low. There was never a reason to load the captured P-51B with...

    German P-51????

    The P-47D-2-RE shown next to the 479th FG P-51D was captured on November 7, 1944. The 358FS/355FG lost two running out of fuel and landing near Liege. The P-47 that went to Rechlin was undamaged, gear down landing - te other a belly landing. Bill Roach was flying YF-U 42-22490 'Beetle" which...

    German P-51????

    Absoutely not. The Germans captured their Mustang on D-Day. Tom Fraser, 4th FG landed P-51B 43-24825 QP-G. Lost in cloud cover late afternoon, disoriented, landed intact in what he thought was an English field - but everyone he met spoke German. It went to Rechlin until captured by US forces...

    Mathematics in aircraft design

    I haven't heard a peep. I suppose best approach would be to contact Smithsonian to see if Mustang Collection still available - maybe Aer Library to see is their copy has the MISC folder.

    Brad - I prefer to upload the folder just once. If the website here doesn't permit it I will send the stuff to you. I just sent an email to Admin about uploading into Media

    The Misc folder contains three reports - 2 structural and 1 Performance - total ~ 80Mb, 500+ .jpg docs. I can send vis Wetransfer to an email address. Does this site have a destination address for docs?

    Mathematics in aircraft design

    I mentioned this once above, but a PhD in 'practical" stress analysis is imbedded in the MISC folder f the Smithsonian P-51 Mustang Collection. Both a 500 page NAA Report of the structural analysis of the P-51D-5-NA wing as well as the 70 page NAA NA-8449 Performance Analysis for the P51D-5-NA...

    Vigilant/Mark - I agree your comments about 'deathless prose' regarding Peery. That said, IMO, understanding his material and applying it correctly is a minimum to proceed in detail stress analysis.

    Mathematics in aircraft design

    I believe RDJ reduced your question succinctly - namely "In general, my point is to not worry too much about the math. That will be the least of your design hurdles". As I reflect on me - at 23 with a MS in Aero, match through Calculus of Variations, steeped in Navier-Stokes and annointed in...

    What is your dream warbird?

    My father's first victory credit was on his first mission on D-Day. The 354FS/355th FG caught 15 Ju-8s trying to sneak to the beachhead at dusk. They shot every one down - SG 103 near Janville. A training squadron with very experienced instructors called to duty when the invasion started. Your...

    Wanted to purchase: Fluid Dynamic Drag- Hoerner

    I'll sell my Hoerner for $100 via Paypal. Like Mike I will not be designing aircraft anymore.

    Wanted to purchase: Fluid Dynamic Drag- Hoerner

    Fluid Dynamic Drag by Horner is a solid aero book, but raises the question "what are you looking for?" If your primary objective is to understand the basics of drag and how to estimate parasite drag components 'the way they done it back then', it is hard to beat and you don't need higher math...
