    BF-109 Aerofoil Question

    If you're still looking for this info, I've come across this thread and turned that mess into a .DAT. I'm not sure where that info came from or how to put a 2R1 airfoil together myself so these may not be 100% accurate... and i'm not sure if the tip foil is for early or late 109s :/ Here's a...

    Military Design Standards

    Thanks guys! Just to be clear though, I'm not looking for a means of ensuring your design meets the requirements, Just the requirements themselves. I'll take a look at the books though... I'm sure the contracts would specify these things but I feel like over time the gov could just publish some...

    Ultimate loads compression in aluminium

    What sort of fatigue would resonance cause; how would you compensate for that? :lick: (or perhaps just vibrations, lol)

    Black Fury

    Preventing tip stalls are a matter of design; although an AOA gauge would assist a pilot in knowing how close he is in stalling.. or not. :ban: AOA

    Crescent Wing Design

    Hi guys :) I was sure that it had been brought up here before but I just couldnt find it using the search tools (so maybe it hasnt been mentioned). I'd like to know what you all think about crescent wings; how they compare to elliptical wings and/or your typical rectangular wing. I'd thought...

    Help in deciding on an aircraft

    Ah Ha, how about Team Rockets F1? It is all metal, has quick build option, a two seater... cruises at 230Mph.. 3500fpm initial climb rate and 1000 mile range at 55% power... which may or may not be 230Mph.. probably not. It does use a Lycoming IO-540 though... and it does need 52 gallons of fuel...
