DCS 2.5.6 Open Beta

Development Report #11

2.5.6 Open Beta - This month we have been working to complete DCS version 2.5.6. Some extra time was needed to ensure a smooth transition from 2.5.5 both by our team and our 3rd Parties. You can expect to see the first 2.5.6 Open Beta in early February. We look forward to sharing it with you in the near future.

Development Report

Last month we spent a lot of time on AIM-120 missile CFD research, in addition to our previous computation (which was primarily aimed at deriving accurate zero-lift drag).

We have obtained many other aerodynamic parameters such as pitching moment and normal force coefficients, damping moments etc. To ensure realistic maneuverability, plausible control and stability characteristics we performed more than 200 virtual wind tunnel tests at different control fin deflections and various Mach numbers and angles of attack. Below you can see screenshots from our software with computation result visualization.




Flight dynamics for AMRAAM are almost done and we will move on to autopilot development.

NOTE 1:
AMRAAM test in TWS Mode

I've done a lot of tests in SP since the last AIM-120 update and find that the missile now reliably gets a kill usually in one shot. If you use the TWS radar mode and keep both targets in soft lock until ATC is achieved, then you have a high probability of getting a one-shot kill. The AMRAAM is fully capable of making a 180 degree turn onto target and if sufficient energy remain, will still achieve intercept.

I stand corrected. I'm just now re-running those AIM-120 BVR tests using TWS mode and the AMRAAMs miss their targets!! The soft lock does not work.  

I'll conduct the next test using the old STT method and see what happens.

NOTE 2:
AMRAAM test in RWS Mode

That made all the difference in the world. Stay in RWS, soft lock both raw hits with one depress of the TDC with the cursor over each brick in turn (Mode 4 IFF), then wait until they are within the 40nm range band on your radar scope. TDC depress again on the lead hit, or use your AACQ command with cursor over the hit to lock it into STT. Fire at 25 nm range and again at 20nm if you want some insurance. (Note: The MiG-29S armed with R-27R will normally launch between 27-25 nm = 50 second to impact). Track until D-30 seconds from the time you got a launch warning then go evasive 45 degrees left/right and 45 degrees down. Keep counting until D-40 seconds and reverse left/right 45 degrees back toward your target, keeping the radar locked on the entire time. Undesignate, switch to AACQ and acquire and lock the wingman and fire immediately, then go evasive again while keeping that missile locked on. Double kill every time!!

The previous problems with missing targets that were hard locked STT while in RWS mode were all related to internet lag.
