spawnofbill Posted December 25, 2011 Share Posted December 25, 2011 This is a common misconception, even among pilots, but it\'s totally untrue. A stalled wing still produces lift, just not as much as at a lower angle of attack.Here\'s two graphs of wind tunnel measurements of lift vs. AoA for the same airfoil. The first is for normal (unstalled) conditions:A stall happens when the aircraft\'s AoA exceeds that for maximum lift, which for this airfoil is between 12 and 15 degrees. Notice how the lift doesn\'t drop to zero beyond that point.That graph only had data up to twenty degrees AoA. Here\'s what happens if you keep increasing the AoA:The lift doesn\'t reach zero until the AoA is past 90 degrees—that is, the wing has to be nearly flat to the oncoming wind to produce no lift!The first graph is from Abbott & von Doenhoff, 1949, the second is from NASA CR-2008-215434.You\'re correct. Let me rephrase, a stalled wing does not produce enough lift than what is necessary to keep the plane 'in the air'. Link to comment Share on other sites More sharing options...
NovaSilisko Posted December 25, 2011 Author Share Posted December 25, 2011 I\'ve just performed a successful suborbital flight with vanguard. To perform a successful reentry, set your periapsis to 30,000m, and when you enter the atmosphere, orient yourself to the ground, and turn on SAS. Do NOT attempt to manuever at speeds above 200 m/s, it usually ends badly. Link to comment Share on other sites More sharing options...

venku122 Posted December 25, 2011 Share Posted December 25, 2011 Can this thing go to the mun? Or do I need a TMI stage to get it there? Link to comment Share on other sites More sharing options...
Tiberion Posted December 25, 2011 Share Posted December 25, 2011 Nova: Interesting discovery on my end working on the shuttle;Angular Drag is the bread and butter of winglets more is better for stabilizing things. Try something like 20 and see if it still tries to flip out on launch. Link to comment Share on other sites More sharing options...

NovaSilisko Posted December 25, 2011 Author Share Posted December 25, 2011 I want to download this. Bad. How\'s the learning curve on this beast?It\'s pretty tricky. I\'d compare it to a bit under learning to land on the mun.Speaking of which: Link to comment Share on other sites More sharing options...

NovaSilisko Posted December 25, 2011 Author Share Posted December 25, 2011 How much fuel does the Vanguard have internally? Enough for TMI or just orbiting?Orbital adjustments and deorbiting, pretty much. The TMI was performed by the booster\'s third stage. Link to comment Share on other sites More sharing options...
Guest GroundHOG-2010 Posted December 25, 2011 Share Posted December 25, 2011 your not doing the X37. Could I do a plane as a direct copy of the X37, since there isn\'t a direct copy of a real life planned spaceplane. Link to comment Share on other sites More sharing options...

NovaSilisko Posted December 25, 2011 Author Share Posted December 25, 2011 How much does it weigh? Is it balanced for silisko edition of standardIt should be much easier to get into orbit with standard, I know that much Just calculated it, 1.6 weight units. Might be a little light...
