There is probably a small lip around the edge of the openings (at the top and both sides) to help guide the garage doors. Beyond that, there is no reason why the openings should not represent the limits of the internal space.
Well I have already given you plenty of very good reasons, such as to have a storage area for munitions, equipment and parts to service any helos that land on the helipad as well as to serve as a hanger for small UAVs to help mitigate not having full sized helos embarked at all times.
Now, if all you are doing is ignoring arguments you don't like, then I will see no point in discussing this with you further.
That’s a MASSIVE stretch of a reason and you know it. Look at the back of the Luhu’s hangar and tell me how much “load-bearing” is being done by the side facing the helipad. I’d say maybe 30%, 35% tops. Same thing with the Luhai. Same thing with the hangar-mod Luda. You just don’t need that much wall to support the structure of the hangar. Besides, this ‘structural integrity’ argument already fails to make sense just based on its current setup with two holes. You can’t count the holes as ‘structural support’, you know that, right? In fact I’m willing to bet even creating a hole as large as the port and starboard openings and sticking that right in the middle in place of those two holes, would do just about nothing to compromise the ability of the aft wall to support the roof something it doesn’t even need to do AT ALL.
The structural integrity suggestion was put forward to counter your original suggestion that it would have been possible to cut half of the middle support away to make the opening bigger for a large UAV. The two doorways already account for around half the width of the hanger, and if you cut away much of the middle support, there would be precious little left to support the rear of the hanger.
Structural integrity is of particularly more import to small ships, because unlike their larger cousins, it would be far more likely and common for a large wave to crest over top of a small corvette compared to a larger frigate or destroyer. Thus, the roof of the hanger would not only need to be able to support it's own weight, but also be able to withstand a large wave crashing down on it. Just how big of a wave it can withstand would be down to the margins the designers decide to give it, which in turn would decide what kind of storm such a ship can ride through and which it needs to steer clear of.
You perhaps forgot that there are in fact FOUR walls running along the main axis of the ship at that location, with the two middle walls running at least partially the length of the two outer walls. If those aren’t enough to hold up the roof without any help from the aft wall, the PLAN is using some pretty cheap sh** for construction.
What four walls? I have never seen any pictures to indicate any internal walls in the hanger. I hope you do realize that just because you drew them on a picture does not make them there in reality.
Actually, I don’t believe I made reference to the size of any putative UAV in my reply to you and it actually makes no difference here.
So the comments you made about a dipping sonar and torpedo carrying UAV were what exactly?
I’m talking about how much sense it makes to have a UAV hangar with a door that faces away from the helipad when there is no reason not to have one facing it. It doesn’t matter to me whether this door is the size of a home garage or a B2 hangar door. And you should note that you have been arguing two locations for the putative UAV hangar at the same time: the space just below the HQ-10 launcher, and the spaces just forward of the torpedo launcher.
Well, here is that word that all designers know and which you loath - compromise.
The hanger is not just a hanger, it is also where the torpedo launchers are housed. That changes the requirements compared to if it was just a hanger.
Having one big door in the middle would mean that there is no direct access to the torpedo launchers from the helipad. When you consider just how close to the rear wall of the hanger those torpedo launchers are placed, that presents a bit of a problem for loading and maintenance.
Now, you can load them from the front of the torpedo launchers I suppose, but that would mean that you need to keep an area at least the length of the torpedos themselves (almost certainly more as you need room to safely maneuver them) in from of the torpedo launchers free at all times. Why waste all that precious space when instead, you can put doors behind the torpedo launchers so that when it comes time to reload them, you can push the fresh torpedos onto the helipad, and have all the space you could want to maneuver and position them, and just slip those bad boys straight into the tubes?
To address your second point, I have not been arguing for two places at the same time. I have always said that the space immediately behind the rear control rooms would be perfect, however, it is also perfectly possible and feasible to have the UAVs parked deeper in the hanger. They are alternatives suggestions.
Well, no. You may claim that both of them are needed for a control station, but that does not mean that the PLAN all of a sudden DOES need two windows for a standard helipad when it has never before needed something so wide. Nor has any other naval vessel that uses a helipad of this size.
Which is why I suggested that one of them could be used for the control station for UAVs. Funny you cannot remember that now, yet seem to remember that just fine when you wanted to mock my suggestion. Pick and choose much?
BTW, I have also assumed those are windows, when in reality either or both of them could actually be used for something else, like ventilation.
So which other warship have vents in the rear wall that are that big?
Or they could both be windows but neither of them used mainly for helicopter landing operations, but rather as viewports to the rear of the ship, which can be used as convenient control stations in a pinch.
That's reaching, desperately so. Which other warship has such a design feature?
When someone tries this hard to come up with implausible suggestions to try to cast doubt on a far more logical suggestion, odds are that someone has an agenda other than trying to uncover the truth of the matter.
Right now they are just two holes that provide no structural support and provide no clues as to their eventual purpose.
Really? You have absolutely no clues as to what those windo...sorry, holes, might be used for? Are you sure?
Here is the bottom line: the wall facing the helipad has no need of either the level of structural support you are claiming based on the fact that it’s already proving that it doesn’t, RIGHT NOW, and the fact that other ships have no need of such significant structural support.
Please, go have a look at ship hanger design especially smaller corvette classed ships. There is always significant structural support measures in place, even on the newest ships which benefit most from modern materials sciences and CAD.
Also, the wall facing the helipad has no need of a second control room window because no other ship has needed them in the past for a similarly-sized helipad. So there is still no reason a supposed UAV hangar could not have a hangar door directly facing the helipad.
Unless you want to come out and claim that you know better than the designers of the 056, I would suggest you stop obsessing about how you might have designed it, and instead focus on trying to understand why the designers made the design choices they have.
As I said, the passageways are just as wide as they need to be to accommodate both the swinging action of the torpedo launchers as well as the movement of personnel to and from the helipad. As for the openings themselves, they could easily be that wide to facilitate the reloading of torpedoes after being delivered by helo resupply. You already need passageways to be that wide. This has been demonstrated by MwrRYum’s photo. There is no reason to hinder either the reloading of torpedoes or the movement of personnel by making the openings smaller.
Have you read what I wrote? Having a set of smaller rolling doors for reloading the torpedo launchers and a separate standard standard hatch would not hinder either reloading of torpedos or crew movement if that was all that was intended. On the contrary, having two sets of doors would have it far easier for crew to move to and from the helipad because they would not need to wait for the doors and wind up and down every time the pass.
However, as I have stressed multiple times now, the reason they designed those doors to be as wide as they have is to allow rapid reloading of helos that do land on the helipad, and has a welcome secondary benefit of being perfectly suited to moving small UAVs to and from the helipad.
No, it wouldn’t make the most sense because you have yet to demonstrate there is some kind of space that is being used as any kind of “hangar” in the first place, or that the 056 was even intended from the beginning to potentially be able to embark a UAV at all. Ever.
That is a logical fallacy.
I am not saying 'the 056 will 100% definitely have a UAV hanger', what I am saying is that, from the design decisions and general layout and common sense, I think it is extremely likely that the 056 will house small UAVs in it's hanger.
I am saying that the PLAN has UAVs that would fit just fine through the large doors, there is clearly space for them to house such UAVs if so desired, there is a clear operational benefit to having them onboard, and there looks to be specific design choices made to accommodate UAVs, like the unusually large control room.
If either of us had definitive proof, there would not been any need for this discussion would there?
Because we don't have proof, we need to look at the evidence available to us and try to find the most logical explanations to explain those design choices and that is what I have been trying to do. What have you been trying so hard to do?
Thus far, you have been able to come up with zero credible alternative suggestions for the design choices that the ship designers have made.
If you have an alternative theory for what the designers made certain design choices, I would welcome them. But at the very least vet them in your mind before dumping them here first. Because right now, the suggestions you are making just look like hastily concocted wild ideas you are just throwing out there to try to avoid having to contemplate the ideas I have been suggesting.
That does not feel like the product of rational thought and logical argument, but rather of pride.
Everyone can have bad ideas or make bad calls, there is no shame in that. What is disappointing is for someone to refuse to accept any alternatives because they feel they are wholly invested in a snap call they made long ago and now feel like they need to defined that call beyond all reason and logic to save face.
The fact that the outside of the ship indicates that rear area is longer than the torpedo tubes in no way requires the passageway to extend all the way from the garage doors to the doors right next to the aft mast. In fact the passageways could terminate just forward of the torpedo launchers like this:
This gives that big room even more room, say if they need a real CIC, or a conference room, or something else. There is simply no NECESSARY reason for the passageways to keep extending forward once they are past the front of the torpedo launcher.
You seemed to have put some effort into drawing that diagram, which makes it all the more disappointing. If you had spent half the time you did drawing that thinking through what you are suggesting, I think you would have realized how nonsensical if is to suggest that anyone would put the ship's CIC there.
CICs are typically buried deep within a ship to provide maximum protection, and are also situated close to the primary sensors and weapons so that cables don't need to run needlessly far, both to save on costs and also to help minimize the risks of battle damage cutting those cables.
The hanger is just about the worst place you can think of to put the CIC on a ship. Not only is it extremely expose with only walls of the hanger to protect it, it is extremely close to the main smoke stack, which will be a magnet for any heat seeking missiles. In addition, the hanger is about as far away from mean sensors and weapons as it is possible to get (with the exception of the FL3000 launcher I guess), increasing the length of cabling required as well as making them more vulnerable to possible battle damage by running them all the way along the ship.
The CIC will either be on the bridge, or below decks near the central mass. It's pretty standard in warship design and it's that way for very good reason.
The suggestion of a conference room is even more fanciful. So much so that I am struggling not to mock it, so I will just not bother to say any more on that bright idea.
When you analyses a design, you need to consider the design as a whole as well as it's purpose, strengths, weaknesses, role etc.
Now, having devoted a disproportionately large part of the ship to having a full sized helipad, is it remotely likely that the designers would not bother to include any space for munitions, aviation fuel, spares and equipment to allow them to refuel, rearm and generally make best use of any helos that do land?
There is absolutely no good reason to put the CIC or conference room in the hanger at the expense of the entire propose of having a helipad in the first place.
If they want to use the middle portion as one large room, there is definitely a good reason to partition the passageways, just like the drawing that I posted.
Except the problem is, there is no good reason to put a large room there.
And who said the 056 will store any “munitions, parts, or service equipment” for any helo at all? This is just an assumption that does not require a necessary translation into reality. If they can run a fuel hose out to a helo sitting on the pad, that would be par for the course as far as I’m concerned for this class of ship. The presence of the helipad begs neither any kind of onboard hangar nor any kind of maintenance facility for helos at all. I think that’s what you keep tripping over. You see a helipad and you really want to add something else helo-related, like a UAV hangar or a helo maintenance/service station. Well sometimes a helipad is just a helipad.
Really? Take another look at the design. The helipad is unusually big for a ship of it's size. What other ship design devotes as much deck space (in meters and as a proportion of the ship) to a helipad and cannot re-arm them?
The very design of the hanger doors is a clear indication that they designed the hanger to allow rapid access to both sides of a helo with sizable loads. Does not take much of a leap to imagine what those loads might be.
As for UAVs, well the PLAN already operates such small UAVs on their ships. That is a fact that you will have to accept. if they are operating such UAVs on ships that have full sized helos, why wouldn't they use such UAVs to supplement the 056 which has no embarked helo? Embarking such UAVs would only need 2-3 square meters of deck space per UAV max. Even if they did not specifically design the ship to take them, that is the kind of space they can very easily find and set aside in the hanger of the size on the 056.
It is amusing that you are accusing me to having preconceptions for calling something that looks like a hanger, is designed like a hanger, positioned exactly where you could expect a hanger to be, and have doors like a hanger as a hanger. OTOH, your far fetched suggestions that they would put a CIC or conference room there is based entirely on abstract logical deduction?
Clearly? Again, I think you and I are using different meanings of words. I don’t see kind of clarity in this claim here. Two passageways to “load decent sized loads into both sides of the helo at the same time”??? LOL, which ship has ever created something for that purpose? Please show me, because I REALLY would like to see something like that. But TBH, there is reaching for straws, and then there is reaching for straws. And then there is the concept of multiple passageways for rapid loading of helos on both sides at the same time.
Pointless hair splitting and already addressed.
An unusual design does not equate to, “let’s speculate all kinds of untenable ideas for what the hell might be going on here”, when there are perfectly good reasons for seeing what we see.
How exactly is anything I have suggested 'untenable' by any stretch of the imagination? The only suggestions that are untenable are the far fetched ones you are dreaming up that have no purpose, reason or basing in reality.
Wide passageways on both sides: they need to be that wide to accommodate personnel movement and facilitate torpedo launcher rotation at the same time
Which does not explain why the doors need to be that wide does it?
Wide openings on both sides: there is no reason not to allow easy movement of personnel at the same time as facilitating an easier ability to reload spent torpedo tubes using fresh rounds from the helipad.
As I have pointed out before, the torpedos need to be first moved onto the helipad from racks or magazines in order to load them into the launchers without needlessly wasting internal space. There is no need for helicopters to deposit fresh rounds, and the fact that you keep referring to such shows you have not fully appreciated the reasoning behind the design of those doors.
The lack of a UAV hangar door on the wall facing the helipad: there is no good reason for this if there were an actual UAV hangar. IF there were an actual UAV hangar.
Again, pointless hairsplitting. The Freedom class LCS can carry two Seahawks, but it only has one hanger door. What does that say about the LCS' ability to carry two helicopters? Absolutely nothing.
Normally, a warship would not have enough width to design a hanger other than one that has direct access to the helipad, it is also convenient do have such a direct path. But there is absolutely no reason why a hanger cannot house something just because it needs to make a turn to get access to the helipad.
