Got this new tweet from @lylegoldstein.

Needless to say, quite an interesting claim from the Russians.


Didn't know that China managed to get their hands on the Yak-38 S/VTOL fighter in the 1990s until now.

The only instance we know about such interactions is when Lockheed Martin got into a partnership with Yakolev on the Yak-131 S/VTOL fighter's development in the same time period.
You should double check with alternate souce for credibility of this article. Look at the title of his article, which is ending with a "?".
Also, I didn't manage to find any mention on the Chinese internet WRT the claim of China having acquired Yak-38s from Russia in the 1990s, either.

Yet, in the meantime, what I did notice is quite a number of mentions on the Chinese internet, claiming that China had bought the blueprints of the R-79V-300 engine that were used on the Yak-141 instead.

However, I am unable to independently verify the authenticity of these claims, so please take these claims with a massive pinch of salt.

Maybe someone here could ask Yankee, Shilao, Ayi, Orca, and/or someone else who are more knowledgeable on the matter?

I can neither read nor understand Russian, unfortunately.

Anyone here understood Russian?
It says:

It's not a Yak-38, not a Harrier, what is it?

Recent chatter from sources suggests China is focusing on creating a VTOL aircraft. There were many claims, at times contradicting one another. However, there's no smoke without fire. Plus the Chinese are good at keeping a secret, probably better than anyone. So we can conclude they are indeed working on VTOL.

An article about a new pulse production line for ejection seats. The line has shortened final assembly time by 50% while improving quality. It also mentions that the output for a certain ejection seat model has increased by 50% in 2022 compared to the previous year.

发展的重要战略机遇期,航宇弹射座椅主业板块的科研生产任务剧增,现有的生产组织模式难以满足客户需求,如何探索一条提升装配效率的弹射座椅总装脉动生产线迫在眉睫。为有效提升弹射座椅装配效率,航宇基于精益生产理念、信息化和数字化技术,通过全面工艺流程再造,构建了数字技术赋能的弹射座椅总装脉动生产线,有效缩短了生产周期,提高了弹射座椅的总装效率和质量。

规划引领,形成精益布局航宇基于精益生产理念、信息化和数字化技术,以提升装配效率、满足客户需求为目标,按照“整体规划、紧急优先、分阶段实施”的思路,采用点、线、面的逻辑推进方式,通过精益单元/数智化产线建设,最终形成“1+6”布局的弹射座椅总装模式,即1条弹射座椅总装脉动生产线,6个与其配套的椅盆、组合动力机构、伞箱等部装单元。

作为航宇首条以提升弹射座椅装配效率为目标的总装脉动生产线,从最初的概念设计,到投入使用仅仅用了几个月的时间。“该生产线不但结合国家智能制造指导要求与公司战略目标,而且还因地制宜引入了信息化和在线检测技术,提升了装配、检测效率,实现了装配过程标准化、现场管理精益化、生产管理数字化,提高了生产线整体装配效率和质量。”航宇副总经理杨峰说。

重构工艺流程构建总装脉动生产线为顺利推进弹射座椅总装脉动生产线建设,航宇本着“工艺先行”的原则,在工艺技术系统启动了全面工艺流程再造工作,并按照产品脉动和工位固定设计相结合的原则,综合柔性和通用性,将弹射座椅的整个生产工艺流程进行重构,分配到多个装配工位、检测工位、总检工位,每个工位配备了装配工作台,产线配置自动AGV小车实现产品在各工位间顺利流转,加快生产节奏,提高生产效率。其次,按照节拍拉动弹射座椅装配进程,对每个工位的工序按照ECRS原则进行调整、拆分、合并,对工位时间进行平衡,提高产线均衡率。同时,采用无纸化工艺方式对组件中各零组件的装配流程、装配位置、安装方向、装配要求、注意事项、检查要求等内容进行进一步细化,并在各工位配置标准作业指导书,用于指导操作人员和质量检验人员。

数字化技术赋能精细化管理,实现现场无纸化,提升组织效率依据航空智能制体架构要求航宇以航空运营管理体系 (AOS)为指导思想,聚焦弹射座椅总装生产线运营管理、装配检验全流程,将基于弹射座椅总装脉动生产线总体架构分为四层,分别为数据采集层、应用层、业务层和展示层四层。

在装配过程中,采用单台次管理,每台座椅均有唯一编码,并与工艺卡一一对应,使管理精准化,可追溯;为配合总装脉动生产线的运行,实施了装配MES系统,功能覆盖生产计划、物料配套、质量管理、制造执行等生产过程,实现了计划下达-派工-配送-装配-检验交付等一站式系统过程控制,形成了“批次管理、单台流转、脉动生产”的新型生产业务模式,节约了大量的人力和物力,达到模块式管理,周期节点精确定位、可视、可控、可追溯的完整生产线管理体系。

为适应某型总装脉动生产线单件流管理,通过设立产品二位码标识卡进行各工位件流转,实时记录报工信息和检验信息,通过实施装配MES和机加MES、供应链系统等信息化系统集成,实现生产领用、配送的无纸化;通过信息化、数字化技术实现基于信息化系统的检验记录自动生成,取消总装脉动生产线工艺装配大纲里《装配调试、检测记录表》《装配工艺流程卡》等数据记录的手工填写减少操作者和检验员手工记录的工作时间,做到配记录的可追溯,逐步建立生产管理数据库,做到管理先进、使用方便、查询快捷。

“目前,该生产线从下达生产任务,工位零件叫料,物料配送区进行分拣、配送,到工位操作者进行报工、完工及信息化检验等一整套流程;生产状态集中监控,各个工位实时进度尽收眼底,智能管控、智能生产,航宇正将弹射座椅生产‘智造梦想’一点点变为现实。”杨峰说。

弹射座椅总装脉动生产线建设运行后,产线平衡率由42%提高到84.3%,总生产周期缩短了50%,真正实现了“问题显性化、操作标准化,治理制度化”,确保了座椅重要零组件的安装正确和产品质量的一致性,减少了批次性质量问题,提高工艺的可操作性、可检验性。2022年度,某型弹射座椅年产量较去年增长50%以上,创历史新高,航宇将“不可能”变成“可能”,满足了客户要求;并实现质量指标的达标,即故障率不大于0.2%和一次交检合格率不小于99.5%质量指标,全员质量意识得到较大提升,通过以上举措的实施,进一步缩短了生产周期,提高火箭弹射座椅的装配效率和装配质量造“入脑、入心、立行”的精益氛围。
