Will the AIM-260 have a dual pulse motor like the PL-15?

Impressive.

With each landmark breakthrough, China clarifies its return to place as a world leader in the sciences and technologies, technologies which in accordance with Confucian values, China intends to use for the sole betterment of mankind. In recognition of the true benevolence of China, the world is now set to leave behind the times of destructive Western leadership.

will you get a real job instead of being a professional shill?

>>64031951 (OP)
Why does the more fuel of the AIM burn faster than the first stage of the PL and why does the PL keep coasting until its second stage, even though they stopped thrust at the same time?
Also this implessive child's cartoon has convinced me that china is indeed very stronk.

No info, zero, nil, and the color bands have a 4th grey band that it's abnormal.
There're alternatives like "Attitude control motors" more fuel efficient, hybrid rockets, etc. I would simply wait because thing like the AIM-120-D+++++++++++++++++++++++ are tiresome, optimizing the trajectory or seeker doesn't change the NEZ, it only makes the effective NEZ closer to the ideal NEZ, but thinking the opponent will never detect a missile is wishful thinking.

Normally the AMRAAM is hitting something by the time it runs out of fuel. Making the missile more complex doesn't make it more lethal, in fact, this was already abandoned 50 years ago when American designers thought it was retarded.

>>64031951 (OP)
Well, it's being produced by Lockheed Martin, and they've been manufacturing dual-pulse motors for the PAC-3 MSE since 2015 (in service since 2016), so it's certainly possible.

>dual pulse motor
Is the Chink's retarded way of saying it has two motor stages in the same housing without dropping the first stage.

If tue chinks had any actual intelligence they'd be embarassed by it.

Doesn't matter. Neither will ever reach the efficiency of an airbreathing ramjet like the Meteor.

Implessive

>>64031951 (OP)
that's not how it works

>>64031951 (OP)
Mostly because it's kinda pointless. Modern missiles like the AIM-120 are lobbed up into thinner atmosphere where air resistance is minimum and then dive down on the target to reclaim that kinetic energy.

The initial pulse of a dual pulse motor is smaller than a single pulse so the PL-15 won't get to the same altitudes the AIM-120 can. Instead, it maintains a slower overall speed to reduce air resistance. If we assume similar rocket fuel then you'll get very little actual range improvements with most of the gains being taken up by the additional weight of a firewall to keep the first rocket from igniting the second and an entirely separate ignition system for the second rocket motor.

The real loss, however, is in the Minimum Avoidance Range. Since the Dual Pulse motor is slower the target has more time to evade and a fast enough target has more time to escape the PL-15's maximum range.

>to reclaim that kinetic energy.
It's mostly to reduce drag because an increase of altitude of 15 km will barely reduce the KE by 15-20%, temporary, but 15 km of extra altitude reduces air density to a fifth

>>64032962
Didn't I mention drag? I could have sworn I mentioned drag.
> 15 km of extra altitude reduces air density to a fifth
Seriously? I knew thinner air would reduce drag but I didn't think it would bet That effective.

>>64033036
An decent approximation is that it falls exponentially, approximately halving each 5.7km.
> P = Po / 2^(alt in km/ 5.7km)

>>64033067
a decent*

before worrying about missiles, they should fix their engines first.

>>64031951 (OP)
this is not how physics works

>>64031951 (OP)

the aim260 will basically be an aim120 with smaller/ updated electronics, (probably) no mid body control surfaces, and the opened up space filled with a longer propellant load. But that’s fine. An Aim120D with 40-50% longer burn is a bitching missile

Not really. Missiles burn out in like 8-10 seconds.
Typically missiles loft by flying upwards into thinner atmosphere and coast at higher altitude than the target to preserve energy. Then when getting closer to target the missile dives.
Hitting while the motor is still burning means the shot was taken at very close range.

>>64031951 (OP)
It's possible, though I'm not sure how worth it the USAF sees it to be relative to just manufacturing standard rocket motors. Dual pulse gives you very slightly more total range (2-5% more) and a bigger NEZ, but you also end up taking anywhere from 10-25% longer for the missile to get to the target, which gives them time to notice the launch and achieve a kinetic defeat. It's a tradeoff no matter which way you go so who knows what they will end up deciding

>>64031951 (OP)
Single medium thrust pulse > dual pulse, there's a reason why AIM-120s went from dual pulse to single pulse as ranges extended. The high thrust first pulse is great if you need responsiveness at close range since it gets you up to speed fast, but then you lose out in terms of drag losses. The sustainer would have to be super long burning, low thrust to bring back that edge, and you're kinda fucked in that regard since the spent first pulse decreases your efficiency, especially as you decrease thrust due to chamber pressure and nozzle issues, regardless of the layout, whether it be in the fucktarded manner you've posted or in a more traditional dual pulse motor. You also still eat greater drag losses for no real gain at long range. Single pulse has advantages in burn efficiency, and while it's a bit of a compromise in shorter ranged engagements, it's better suited to those longer ranged engagements, when appropriately optimized. Dual stage missiles are a different beast however, and are likely what AIM-260 will use. Ramjet designs suffer from having to need air, so they stay lower, somewhat negating the advantages of their higher propulsive efficiency. High altitude lofting does have its disadvantages too though in that you've got worse ability to react to enemy maneuvers (lower drag, but for the same reasons lower lift), but since it fundamentally forces the opponent to have to react defensively I think it still makes more sense tactically. A-pole is also important, it won't matter if your ramjet missile can reach out twice as far if the opponent's missile will reach you before your missile goes active on them.

>>64034121
Nah, dual pulse isn't always superior, it depends on how the pulses are configured. A well optimized single pulse motor can outperform a dual pulse motor in range, it just will have a worse min WEZ

>>64034248
I'm assuming the pulses here in this scenario are able to be activated at high altitude as a final pulse to speed up as it dives on a target or as a "range extender" where the second pulse avoids some of the drag issues by keeping the overall average velocity lower with the 2nd stage not activating until drag is lower due to both lower speed by the time it turns on and due to higher altitude when the burn happens. Obviously you can't change the actual size of the stages given that they're a function of motor size and fuel mass and you have to also optimize for a combination of range extension and also terminal velocity gain but I am guessing this is how the PL-15 works. Either way I don't know how the hell the AIM-260 is going to get anywhere near the proposed range given the space constraints they have to work with. By being forced to keep the form factor very close to the AMRAAM in size I don't know what more they can realistically do to hit the ~150 nmi mark they are/were aiming for

>>64031960
Took you long enough, comrade. Now let us face the glorious dawn of the new Chinese hegemony shoulder to shoulder.

>>64032019
Yeah, and now they're at risk of getting sniped from hundreds of kilometers away

>>64032916
But isn't the aim-120 shorter range than the pl15? It may be slower ins peed but the range it can cover is almost double if not more than double the aim-120s, even the d model. Evading a slow missile is fine enough, unless you are ambushed by it from long range without ever seeing it coming.
