hi all,
thanks so much for your advise on airfoils. i've bought and am reading andy lennon's book (awesome work!) and i've got profili and the pro version is on its way from italy.
now i need some kind of baseline data:
rc jets are apparently appreciably faster than prop driven planes.
what kinds of airspeeds are to be reasonably expected for:
landing
cruise
top speed
for existing jets?
i'm aware that weight, design and aerodynamics have a lot to do with this, but at least it will give me an envelope to work within.
from my research on the web, it looks like 25 mph is a reasonable landing speed, top speeds can be in excess of 200 mph.
i'm not sure i want my u-2 flying at 200+ mph, but i'd like to be able to correlate thrust and airspeed, all other factors being equal. lennon's book didn't address jets at all, and the web is woefully difficient in this particular kind of data. there has to be some formulaic way to arrive at this information.
my next step is to contact some engine reps and ask them for applications data, but i thought i'd come here first. i learn so much when ya'll take up a subject!
