Made some changes to the T-45 .air file

<< < (2/2)

Stretch32:
The only difference between the Alpha and Charlie that I'm aware of is the glass displays vs. steam gauges. As far as I know all numbers for performance are the same. I've not flown A's since Meridian only has C's but talking to K-ville guys thats the only difference (no airframe or engine mods, same aircraft basically). So the data for both aircraft should be the same. I still haven't found a scanner to upload graphs but what SpazSinbad has available should be just fine. As far as Joe's questions:

1. I think it needs a bit more decel with the boards extending but I need to fly it a little more and get my friend to fly it as well to see what he thinks. 2 opinions are probably better.

3. I'm not really sure about stall speed numbers since nobody actually uses a speed. We considered the a/c stalled at 30 units AoA and that's the only number I really look at. I remember hearing that 85-95 kts depending on power setting was where the aircraft actually stalled but I'm not sure. I'll do some looking tomorrow and try to get some better figures.

SpazSinbad:
AvJoe, thanks. I guess the reason why the performance charts in T-45A are not included in T-45C. My knowledge of this aircraft (and variations) is very vague at best.

average_joe:
Think I did it ... reverse engineered the CL vs AoA curve ... plus one anal extraction.

Aircraft flys very close to correct airspeed for on speed AoA. I was at 124-126 KIAS. Might still be a knot ot two slow as I was close to a full fuel load. Took off from Pensacola at 5 min later dirtied up for an on speed check.

Also bumped up the speed brake parasite drag contribution per Stretch's comment. Will send the AIR file to Stretch, Sludge, and Spazsinbad.

Spaz ... need a good e-mail address. My e-mail didn't like the address that's on your profile.

Not sue the reverse engineering is totally accurate given the size of some of the scaling values in the .cfg file but it seems to work across the flight regime.

By the way any input on engine performance will be appreciated ... I think its overpowered in the 70-85% regime. I was at 3000' 430 KCAS at 75% power ...

SpazSinbad:
AvJoe, e-mail corrected (dropped old one of two). There are performance graphs for the Goshawk A model in that NATOPS AFAIK without checking at moment. Do you have NATOPS for Goshawk?
