KJ-600 carrierborne AEWC thread

[asif iqbal]

yes and also fixed wing AWACS taking off from a carrier is another thing

one of the most challenging aspects of carrier operations is to get a fixed wing AWACS off it

huge radar balanced on a aircraft which is small taking off from a ski jump or carrier in the middle of the ocean

massive deal and theres a good reason outside US hardly anyone has managed it and even less try and attempt such a project

hugely under stated but one of the most important components in carrier air wing

China demonstrating such capability will certainly raise the stakes

I'm sorry if i'm misinformed..but awacs taking off from a ski jump? Isnt that impossible since kj600 is turboprop and turboprops though efficient aren't really powerful..
I don't see how a hawkeye like aircraft can fly off a carrier without catapult assistance.

KJ-600 requires a catapult. It won't be flying off CV-16 or CV-17.

 

[asif iqbal]

Yes meant carrier

An article detailing one of the engineers at XAC revealed that the H-600 has completed its drop test in late 2018. This would suggest that a prototype is now under construction, which would be in line with PB19980515's earlier prediction that a maiden flight could be expected in 2019.

我们都是追梦人|从“三无”到国内第一——记2018年先进工作者，全机落震试验负责人杨小斌
航空工业一飞院 Yesterday

杨小斌，男，汉族， 1974年 6月出生，陕西凤翔县人，毕业于北京航空航天大学飞行器设计专业，研究员。1998年 8月至今一直从事起落架强度设计研究工作，先后参加JH7、JH7A、小鹰500、ARJ21、大运等多个型号的研制。现任某飞机起落装置强度设计专业主任师。


肩负“三个成为”的使命担当，发扬“飞豹精神”的文化传承。

2018年12月13日，试验现场，伴随着一阵热烈的掌声，国内第一个全机落震试验顺利通过验收，这标志着我国成为世界上第二个掌握了全机落震试验方法的国家，也为国内开展此类飞机载荷研究奠定了基础，提供了一个新的途径。作为该项试验的负责人，杨小斌在那一刻终于松了一口气。回想起之前数百个日日夜夜辛苦攻关的场景，他也忍不住热泪盈眶。“这是我们应该付出的，是值得的。”在聊起这项试验时，他如是说。

国内之前没有开展过任何正向研究，没有经验、没有参照、没有基础。在接到某飞机起落架强度设计任务时，杨小斌面临的就是这样一个“三无”的情况。在这种情况下，作为主任师，他没有逃避，也没有抱怨，而是沉下心，带领着起落架强度设计团队，先对面临的挑战和专业内的技术手段进行了全面的分析和梳理，让大家对面临的挑战和困难有了一个全面的认识，同时，他也发现按照当时专业内的设计手段，想要实现载荷设计零的突破，那简直就是异想天开。在那种情况下，他认识到要想在技术上实现突破，首先要在设计手段上有所突破才行。常规的设计手段，都是基于静强度设计思想，依据设计规范计算载荷，然后再进行强度分析和试验，仿真分析在当时仅作为辅助分析和检查使用。而面对某飞机使用环境的特殊设计要求，杨小斌在认真分析后，决定改变以往的设计思路，以仿真分析作为主要设计手段来寻求突破。

这个决定在开始的时候，大家都认为风险太大，一方面是在整个行业内还没有人敢于将仿真分析结果作为设计的主要依据来使用，大家对仿真分析的准确性存在一定的质疑，另一方面当时专业内还没有人能够掌握此类飞机仿真分析方法的技术人员，大家认为条件还不成熟。为了打消大家的顾虑，杨小斌给大家细致地分析了某飞机所面临的挑战和开展仿真分析的可行性，他说：“我们应该看到，系统仿真是飞机设计技术发展的一个必然趋势，是将来每个技术人员都需要掌握的设计手段。现在某飞机设计给了我们一个提前开展的机遇，这既是一个机遇也是一个挑战。这个时候，我们除了迎难而上，没有别的路可选。”于是，在他的带领下，起落架强度设计专业展开了“设计大练兵”。根据在其他型号上开展仿真分析的经验和基础，杨小斌对某飞机的载荷设计环境进行了仔细分析，确定了开展载荷仿真分析的几个重点方向，方向有了，他便开始带领大家对某飞机特殊的载荷设计情况进行一遍又一遍的仿真分析。在回忆起那段仿真分析的日子时，杨小斌很有感触的说：“我们这是摸着石头过河，一边摸索，一边前进。许多时候，大家做着做着发现方向不对，然后又回过头来重新开始，像这样不断反复的情况，在那个时候，太常见了，但是参与其中的每个人都没有放弃，没人言苦，没人喊累，大家都是憋着一股劲往前努力，直至把这条路趟通。”

功夫不负有心人，在经过无数遍的探索之后，杨小斌带领着他的团队终于掌握了此类飞机载荷仿真的方法，攻克了某飞机载荷设计的难题，这为后来在详细设计阶段的载荷优化打下了坚实的基础。同时，经过他的努力也让起落架强度设计专业的设计手段得到了大幅提升。这为其他型号的起落架强度设计提供了一个新的可供借鉴的途径。

在带领着整个团队开展仿真分析的同时，杨小斌心里也在一直规划着另一件事，那就是如何通过试验对仿真分析载荷进行验证的事。虽然说通过仿真的手段可以突破飞机载荷设计的难题，但是没有具体的数据支撑，由仿真分析得到的数据仍缺乏一定的说服力。解决这个问题最好的途径就是进行飞行实测，但是按照我国目前飞机的设计情况，实测是根本不可能的，这样一来就只有通过试验来进行验证。国外的做法是开展全机落震试验，对这个试验，全世界也只有美国人开展过，除此之外，还没有那个国家能够开展这个试验。国内能不能开展这个试验？怎样开展这个试验？成了横在杨小斌面前的又一座大山。

由于国内还没有开展过全机落震试验。当时，从上级机关到试验单位都对实施这个试验没有信心，为了打消大家的顾虑，杨小斌提出先开展全机落震摸底试验再开展全机落震研发试验的试验设想，并对两个试验的具体实施方案进行了详细设计，经过向总师系统详细的汇报之后，他的试验设想得到了总师系统的支持。2015年全机落震摸底试验正式开始，该试验是利用一架验证机先对试验设备、试验方法以及仿真分析方法进行校验。2016年全机落震摸底试验顺利完成，这标志着我国具备开展全机落震试验的条件了，也让所有人关心这项试验的人轻轻松了一口气。但是杨小斌作为整个试验的技术主管，还来不及松口气，就转身投入到了全机落震研发试验的筹备中。

经过一年的筹备，2018年全机落震研发试验机正式进入试验厂房。试验机进入厂房，也标志着试验机的改造工作正式开始。大量的改装工作，需要有人从中不断地进行协调。而且全机落震试验对试验机的要求很高，也需要设计在现场进行配合。那时候，设计这边的仿真分析工作也进入了最后攻关的阶段，需要大家集中精力进行最后的冲刺。为了保证两边的工作都能够顺利进行，杨小斌毫不犹豫地承担起试验机改装协调和现场配合工作。当时正值夏季，那时候经常会看见他顶着大大的太阳，骑着车子在试验单位、西飞公司和单位之间来回穿梭协调，等到了试验厂房，他还得时不时地爬上飞机，配合改装的工人进行施工。除此之外，仿真分析这边遇到问题时，他还得赶回来与大家一起进行分析讨论，问题解决后，他又马不停蹄地赶往试验厂房。整个夏天，他就这样来回奔波，却毫无怨言，而正是因为有了他这样忘我的付出，试验机的改装工作和仿真分析工作都得以顺利完成，试验正式进入实施阶段。

作为国内首个全机级的动态试验，试验参与单位多，外界的关注度也高，而且试验必须在详细设计发图前完成，试验节点紧迫。身为试验主管，杨小斌倍感责任重大，为了确保试验进行顺利，他坚守试验现场，在每次试验开始之前，他都会结合仿真分析结果和前面试验实施的经验，提前预判试验方案的利弊，提醒试验实施人员应该注意的事项。不仅如此，每天的试验完成之后，他总是留在最后一个走，结合仿真分析结果，复盘一下今天的试验数据，然后再与杨卫平副总师和刘成玉副所长安排第二天的试验进程。正是因为有了他这样一丝不苟、细致认真的工作态度和不辞辛苦、以身作则的坚持，该项试验才在上上下下的关注下，克服种种问题，得以顺利完成，使仿真分析结果得到了有效的验证，为突破载荷设计提供了有力的支持。

鲜花和掌声的背后必定是无数汗水的付出
正是因为有许多像杨小斌这样无私耕耘在设计战线的一飞院人
飞机设计才会从技术基础一片空白
实现技术上的突破和跨越

“路漫漫兮其修远，吾将上下而求索。”
技术的探索没有止境
只要我们勇于探索、勇于尝试
相信未来我们会实现更大的突破和跨越
杨小斌如是说。

I hate to say this as I was hoping for a jet but in that form it looks blatantly E2 inspired to say the least.

Form follows function. The Yak-44 looked like an E-2 as well.

Some news via DafengCao:

H-600, the carrier borne AEW aircraft, completed the whole aircraft drop tests in last December.

And his reply to my question on if already a full-sized static specimen is done?

Maybe not 100% accurate, but is good enough to conduct the tests. A sentence in this piece says the drop tests must be finished before detailed design drawings were distributed to factory, so I guess the first prototype is already under building.

Form follows function. The Yak-44 looked like an E-2 as well.

Not as closely as this does.
First the Yak was bigger. Also mounted the Dish differently. Also the beefier nacelles would have had coaxial props as opposed to the conventional types found in E2. Little novelty about E2 is both props rotate in the same direction this is abnormal and causes the aircraft to be eccentric with power changes.
Then there is the folding. this is the closest it ever came to being deployed or built. The Mock up on a carrier deck. Note the way the wings fold here over the top.
E2 fold like this.
Along the sides. And note the Yak has Only two verticals on its tail as opposed to the 4 we see on the E2.
But this far everything is so close to E2 It looks like some one PS' d Chinese markings on an E2.

Like I said I had been hoping for a jet. Something like an S3 Viking with a phased array.
The USN had been looking at that for a time.

All about risk reduction.

Considering this is the PLAN's first attempt at a carrierborne AEW&C and considering all of the other complex platforms integral to a carrier and its airwing and the many firsts that the PLAN would be doing in its history, I think it would be rather irresponsible if they did not choose the most well proven configuration for their own platform if they could help it.

The reason for a turboprop over a turbofan is as simple as fuel efficiency, no other explanation needed. The turboprop is far more efficient at low to medium airspeeds than a turbofan, which allows the AEW aircraft to loiter on station far longer than the same aircraft with turbofans. If this were not the case I'm certain the US and Soviet navies would have used/switched to turbofan AEW aircraft long ago.

All about risk reduction.

There is no risk reduction here. Everything for the PLAN is new as far as an AEW aircraft is concerned in terms of integrating various systems together. And as far as turbofans go, the PLAN is not exactly new to those. A suitable one could be the ones used on the L-15, or another turbofan purchased from Russia. The point of choosing a turboprop isn't about risk reduction, it's about fuel efficiency.
