New AIM120 Changes

[Chizh]

Thanks for the reply Chizh. Does DCS still not modify drag for the motor on condition? If I recall it doesn't, and this results in higher drag during initial acceleration. If this is still the case, is this planned to be changed with coming missile updates?

The body base drag already accounted in the new FM, in particular for the Sparrow family missiles, already migrated to the new FM.

AIM-120s will be soon in the first quarter 2020.

I don't understand. The patch notes say only sub- and transonic zero lift drag, lift induced drag and lift was changed. You say there was nothing more than that but you also state it has "higher supersonic" drag, your wording is unclear.

AIM-120C got next changes:

1. Significantly reduced subsonic and transonic zero-lift drag.

2. Slightly increased of siupersonic zero-lift drag.

3. Reduced lift-induced drag.

4. Increased lift.

 

AIM-120B got next changes:

1. Reduced lift-induced drag.

2. Increased lift.

 

This is all for now.

The migration of 120 to the new FM is planned for the first quarter of 2020.

We have plan to research R-27 in February.

 

PLZ do, Thank you!!!!!

Thanks a lot! Then it seems from the patch notes the "supersonic zero-lift drag" part is missing. Please add it for clarification, as I saw many people were wondering about this.

Well 120B peaks lower too, so i guess it high speed drag increase too?

Also transonic and subsonic missile is already almost dead, how can it be much of a threat to maneuvering target?

basically missile performs better when it's almost useless.

 

Edit: Uploaded side by side tacview with old and new 120C against maneuvering target. It seems that the most helpful thing that makes new missile slightly better against maneuvering target is removal of that stupid pull up during missile start phase :D(in the old missile). If that pull up wasn't there I bet old missile would do as good/or better

Edit2: Added tacview where I used fuselage launched Aim-120C on f-15, since it gives more similar launch profile.

For the aim120C at least ive really experienced a deadlier missile with lots of kills in mp while in good parameters (<11nm low altitude). The aim120b on the other hand still seems super short ranged...

At low altitudes, the missile is capable get a tangible lift and g-load of approximately up to M0.6-0.8.
