The public info says the aim-120D should use sidewinder propellant
The thrust in that graph is wrong and should be bumped up to what the sidewinder 9x has.
If you do calculations the increased thrust kinematics will fix most AIM-120 issues.
The dimensions of the rockets show there is 50 extra lbs in the AIM-120 rocket engine over the sidewinder.
and before anyone comes in and says butbut the rocket fuel doesn’t mean it’s the same thrust!
Yeah and the C5 is not a “significant increase” in performance. This is proof that C5/C7/D should have better thrust kinematics than the A/B because at the moment they don’t at any range.
All you can gleam from it isn’t AMRAAM underperforming, given it has 240s specific impulse in game which seems to be average for AP/HTPB, but Sidewinders being underperformers at 212 if memory serves me right? To make it funnier, 9X block in 2 game is also below AMRAAMs at 232s impulse. Then there’s discrepancy in listed AMRAAM weight, as it claims both A/B and C/D weigh the same. IF, IF you can get C5/D weight down then those 5kg propellant extra would help.
Yeah I’ve seen that and posted it in the AIM-120 thread.
The thrust force is what I’m talking about not impulse time. That would fix most of the problems in the AIM-120C5 and higher. Do the calculations and just bump it up to the sidewinder 9x thrust of 18000 instead of the 15500ish from the “all boost” even though the sustain of the A/B is 13500ish but it’s boost is 22000ish? The missile will have an easier time hitting sideways moving targets within 20km and longer shots will have ~10s chopped off.
The weight discrepancy is that the AIM-120A/B are actually underweight in game. They removed 10KG from the warhead, updated the fragmentation pattern for more fragments and moved the extra 10kg to the motor.
Except improving thrust also improves impulse for given propellant mass.
Even one analysis (from DCS dev?) claiming 265lsp/17800ish N of thrust is still modest 10% improvement, it won’t turn AMRAAM into wunderwaffle everyone copes about.
AMRAAM-equipped fighters can attack several targets simultaneously. The AIM-120C series began deliveries in 1996 and continues for US allies. Joint procurement of the AIM-120D series began in fiscal 2006 and continues today. The AIM-120D features improved accuracy via Global Positioning System aided navigation, kinematics, lethality and hardware and software updates to enhance its electronic protection capabilities against more capable threats.
there it is, the US navy said that the D have more Power than the C, and we get exact the same XD
One could argue about what “more power” (as I’ve termed it) actually means. But what’s undeniable is the fact that the D model has exactly the same, or rather, worse performance than the C model.
Now tell gaijin “Navy said D has higher stats than C”. And to make things funnier, BVVD or who was Ru dev during the stream stated 120D is “improvement that will help US”.
You have amazingly vague “kinematics” which can mean everything and nothing. Meanwhile I bring you that chart I’ve posted earlier, stating C and D share motors and propellant. Is it true? Dunno, but any sekrit dokuments stating 120D has different/more powerful propulsion likely will be shot down by Gaijin own policy of not using classified stuff. Maneuverability is case of no one can prove anything, so Gaijin did a Gaijin.
Which is in game, modeled as well as it can be since C5 entered the chat.
AFAIK it was controls/steering section that was reworked/compacted, to allow more propellant? Motor itself total length didn’t changed, as it is restricted by missile body
Pl12a exist and the seeker of the pl12a has been displayed before and its been mentioned to be in service
Issue is theres no pictures of the missile itself
Only documents stating that the missile is in service and its maximum range
Ccp unfortunately has done a good job keeping the military information secret
