I thought we are discussing whether the Z-10 is underpower or not. Which I disagreed with those who say that it is underpowered. The reason for my argument is simple.
We are not discussing whether it's underpowered or not -- or at least I wasn't.
Underpoweredness, in relation to what lion was fretting over and what I was discussing, was power to weight ratio.
In that sense, Z-10 is not underpowered, because it can obviously perform impressively and also has had weight reductions to compensate for the reduction in engine power.
"What is considered underpower?"
1) The incapability to carry 16 missiles?
2) Lesser armour (which by the way is just a speculation)
3) Lesser speed
I am not seeing number 2 and number 3 though, and the PLA is satisfied with the performance of the Z-10 which also meant that the Z-10 is performing according or even exceeding the expectation of the PLA and so to the people that are most affected (the PLA), that copter is not underpower.
You're fixating a little, I think, on those three aspects.
When I brought up those examples, they were not to demonstrate "underpoweredness" but rather to demonstrate how engine output relates to each of those.
Again, underpoweredness = power/weight ratio,
not combat capability.
And if that is the case, why are we (who are outsider) still arguing and comparing the lighter copter to a heavier one?
Also if we really want to compare, I would say... lets not bring Apache into the picture because it was a different class of attack copter. It would be like... comparing a light tank to a MBT. sure... the MBT is heavier, larger, more heavily armed... but are you saying that there will not be a use for the light tanks? If that is the case, why light tanks are still being manufactured in lots of nations.
What you are comparing here is what I was comparing before vis a vis "what makes a good attack helicopter"
Kinetic performance, armour, avionics, payload, survivability are all metrics we should use to measure attack helicopters and their respective combat capabilities.
The term "underpower" in relation to combat capability is inaccurate, as it suggests a sense of inferiority in relation to another product, and like everyone has said, every military has their own requirements. But I have been using the word this entire time purely as a synonym for power to weight ratio.
But that doesn't mean we can't compare helicopters based off their own merits and consider what may accentuate those merits. In that sense, heavier attack helicopters are simply better, assuming they have the engine power to sustain that weight.
To sum up:
1: Underpoweredness = power to weight ratio, in my book. Z-10, by definition, is not underpowered, because of CHAIC's weight reduction from the prototype to production version as a result of less powerful engines, thus keeping the ratio even.
2: Combat capability is derived from MTOW which allows for greater armour, speed, payload, more powerful avionics, etc, and is all dependent on the maximum output of your engines.
3: Z-10 with WZ-9 engines may be enough for PLA's requirements at present. All good and done, excellent.
4: Z-10 with WZ-9 engines, which is enough for PLA's requirements at present, is less capable than the much heavier AH-64, because AH-64 has a greater MTOW and also more powerful engines to sustain it, meaning more armour, more powerful avionics, greater payload, greater endurance, all while retaining similar aerodynamic performance. All good and done, excellent.
I thought the WZ-10 is kept less capable compared to AH-64 since the beginning of design.
Even since the Z-10 prototype, with the 1250 kw PT6C, Z-10 would have been slightly less capable, I think, yes.
But WZ-16 has a rating of 1500 kw, in line with the AH-64E's latest engine, so a future Z-10 iteration may well be competitive with the apache.
In defense of Asif, he did a comparison of the power to weight ratio before and found WZ-10 comparable to the Tiger and did not find it underpowered.
Agreed. This entire time I've been arguing that Z-10 isn't underpowered, because its power to weight ratio shoudl still be decent. But its combat capabiilty and survivability suffer because of the less powerful engines+lighter weight to compensate.
It certainly could do with more power so that it can mount the heavier 30mm gun and IF suppressor without sacrificing performance.
I actually woudln't mind if the 23mm gun is retained, if an AFV cannot be killed by a flurry of 23mm rounds it probably won't go down to 30mm either. I'd rather Z-10 be armed with more capable avionics, mast mounted radar, much more armour + larger fuel tanks, and a capacity to hold more ATGMs.
The turret would probably only be used for comparatively soft targets, like IFVs, rather than MBTs, which would be the job of ATGMs.
