From ad052ca1c3713d560dff4268828bb3c5e177b53b Mon Sep 17 00:00:00 2001 From: david Date: Fri, 12 Apr 2002 10:18:50 +0000 Subject: [PATCH] Patch from Andy Ross: Try the following patch to c172.xml, which makes the takeoff-rpm modification I talked about*. Hopefully things will be more to your liking; the aircraft maxes out at 2100 RPM while stopped, then the speed increases to something more like cruise as the airspeed grows. If you look carefully, you'll actually see the RPM drop very slightly before it starts increasing. The physical reason for this is that the blades are "unstalling". As the flow attaches to them, they experience a sharp increase in induced drag. I was pretty pleased to notice this little tidbit; it kinda validates the model in an obtuse way. That being said, I have *no* idea if this effect is noticeable in a real aircraft.
