[NEED TRACK REPLAY]AA Payload drag wrong

[raelias]

I have just condected a few tests to determine optimal configuration for A/A

 

Conditions: 20C 29,92inHG @12.000 ft, Full fuel tank, full afterburner top speed, results as follows (All other stations empty):

 

AMRAAM 4 Single launchers: 528 kias

AMRAAM 4 Dual Racks: 528 Kias

AMRAAM 2 Dual 2 Single: 528 Kias

AMRAAM 2 dual 2 pylons removed: 577 Kias

4 Dual empty Racks: 585 Kias

4 Empty Launchers: 548 Kias

4 Pylons: 650 Kias

Clean: 689 Kias

 

So as we can see, we get the exact same top speed by carrying 8 Amraams on dual racks, or 4 on singles, so either the drag for singles are too high (my conclusion since I couldnt push past mach 1.01 with only 4 missiles on the aircraft) or the drag for duals are too low.

 

Feel free to draw your own conclusions or repeat the tests in the same condition

 

Cheers

I'm not going to post the docs here because it's against the rules but there's little drag difference between single and double racks IRL.

 

Well there is the drag of double the ammount of amraams and 4 double racks extra, certainly there is something very wrong with either the single ou double drag

Single, wing pylon, AIM-120 launchers are not a realistic configuration for the C model Hornets, per my investigation. They have no published Drag Index, and there is no photo evidence of this configuration.

 

Also I don't know why any effort is being spent modeling pylon drag. The removal was supposed to be for demonstration teams (visual effect only), and they don't push the jets to maximum speed during airshows...

Have confirmed, has been this way at least for a year.

 

Other payload drag bugs have been fixed recently, but not this one. So

 

Nobody use single AMRAAMs on a hardpoint, you will go slow. Use the double racks and then dump them as soon as they're empty. Bonus points if you use up one side first and dump that rack.
