景德镇:披星戴月的直升机人 千年瓷都景德镇东郊南山之麓、南河之滨,同样有一群异常忙碌的直升机人。航空工业直升机所坐落此地已近半个世纪,走进园区,楼宇高耸,花团锦簇,优雅的环境和人们匆匆的行色给人一种紧张有序的节奏感。 某型机科研团队今年以来的工作状态又是怎样呢?总师冯胜全介绍,该型直升机研制意义十分重大。为确保装备好用管用,冯胜全带队与客户进行了充分沟通,了解使用需求,后来产生的方案就是基于用户需求的共识。 总体气动研究室副主任张威将这型直升机比作帅小伙,外形设计漂亮,不仅长得好看,而且还非常内秀,性能指标没有下降。直升机体型大了,有效载荷却不能减少,只有从其他地方把重量抠下来。负责总体设计的李黔为此费尽了心机。好在有一个擅长技术攻关的青年团队,他们大多是近几年入职的硕士和博士。硕士王之良在机身阻力方面是主力,而博士徐明则在多方面显示了才华和干劲。 结构室副主任吴硕表示,这型机有许多新研项目,例如驾驶舱、整个机身结构、起落架,在详细设计阶段,结构室发图量接近50%。为了保证进度,他们尽可能把工作往前赶,起落架的图纸早在去年底就发往主机厂了,结构发图到今年6月也基本完成。 吴硕介绍,原有型号是钣金结构,现在采用的是复合材料,零件实施了整体化设计,这就使机身寿命大大延长,也有效提高了制造质量。与直10相比,驾驶舱防弹能力更强,单位重量则有所减轻。之所以能够取得这些进步,是因为充分借鉴了直10等型号的研制经验。吴硕说,大家的干劲也是重要因素,在近期评选优秀项目负责人时,大家一致选出了老党员程小青。程小青负责技术把关,协调工作特别繁杂,但是把工作交给他总是令人放心,他的特点是主动,而且非常细心。 这个型号有许多工作属于第一次,全机电缆优化布置是其中之一。电气特设研究室副主任曾庆吉介绍,目前的电缆布置给人直观的感受是整齐美观,电缆的重量、重心位置都清晰了,对于后续维护将非常便利。那为什么能够做得这么好呢?曾庆吉告诉我们,这得益于设计手段的改进,他们采用了新的软件,并且进行了二次开发,设计员杨庆在这方面贡献很大。 曾庆吉说,型号没有沿用过去的直流发电系统,进行了很大改动,做了可以兼容进口和国产设备的双构型设计。这项工作难度不小,科研人员做了深入钻研,经过多次讨论,找出两套设备的差异,不断调整设计,经过一个多月的努力,达到了比较理想的状态。 系统研究室燃油设计主管杨勇志介绍,这个型号的燃油系统也是全新研制,为了把4个油箱贴住两侧短翼,在保证油量不减的情况下,油箱的形状一改以往的长方形,变得不规则了,不仅如此,油箱的防弹防爆标准更高了,他们首次在直升机上采用了橡胶油箱,油箱管路的复杂性大大提高,在设计过程中,流体仿真软件的应用为解决问题提供了有效帮助。杨勇志说:“起初还犯过错误,导致加油时偏向左侧的油箱,重新设计后才使得供油均衡。为了任务,组里的同事们也是拼了,周佐俊的孩子刚满1岁,夫妻两地分居,他时常加班到半夜,有一回不知不觉干到了凌晨。” 所里的人都知道强度室有个钱学森,这回他在型号研制中和同事们一起攻克了在机舱内系留大质量设备这一关键问题。钱学森工作紧张的时候一忙就到了深夜两三点,“虽然累,但是内心充实,难题因此也就一个个被攻克了”。

Jingdezhen: Milky way porcelain wearing the millennium porcelain are the eastern outskirts of Jingdezhen Nanshan Lu, Nanhe in the same group of unusually busy helicopter. Aviation industry helicopters are located here nearly half a century, into the park, towering buildings, flowers, elegant environment and people in a hurry the color gives a sense of tension and orderly rhythm. A machine research team work status since this year is what? Feng Shengquan division general introduction, the significance of this type of helicopter development is very significant. In order to ensure that the equipment is in good use, Feng Sheng led the team to fully communicate with customers and understand the requirements. Later, the solution was based on the consensus of users' needs. Zhang Wei, deputy director of the overall aerodynamic research this helicopter is like a handsome guy, beautiful shape design, not only look good, but also very Neixiu, performance indicators did not decline. Large helicopters, the payload can not be reduced, only from the rest of the weight pull down. Li Qian responsible for the overall design for this effort. Fortunately, there is a young team specializing in technical research, most of whom are masters and Ph.Ds in recent years. Master Wang Liang in body resistance is the main force, while Dr. Xu Ming shows in many aspects of talent and energy. Wu Shuo, deputy director of the structure room, said that this machine has many new research projects, such as the cockpit, the entire fuselage structure and the landing gear. In the detailed design stage, the number of structural rooms is approximately 50%. In order to ensure the progress, they try their best to catch up with the work. The drawings of the landing gear were sent to the OEMs as early as the end of last year. The structural plan was basically completed in June this year. Wu Shuo introduction, the original model is the sheet metal structure, now using a composite material, parts of the implementation of the overall design, which greatly extended the life of the fuselage, but also effectively improve manufacturing quality. Compared with the straight 10, cockpit bullet-proof ability, weight per unit has been reduced. The reason why these advances can be made, because of fully draw on the straight 10 and other models of research and development experience. Wu Shuo said everyone's motivation is also an important factor in the recent selection of outstanding project leader, we unanimously elected the old party member Cheng Xiaoqing. Cheng Xiaoqing is in charge of technical checks and coordination and is particularly complicated. However, it is always reassuring to hand over his work. He is very active and very attentive. This model has a lot of work for the first time, the whole machine cable layout is one of them. Zeng Qingji, deputy director of the Electrical Special Laboratory introduced the current cable layout gives intuitive impression is neat and beautiful, the weight of the cable, the location of the center of gravity are clear, for the follow-up maintenance will be very convenient. Why can we do so well? Zeng Qingji told us that thanks to improvements in design tools, they adopted new software and conducted secondary development. Designers Yang Qing contributed a lot in this respect. Zeng Qingji said that the model did not follow the past, the DC power generation system, a great deal of changes, made compatible with imported and domestic equipment, dual-configuration design. The difficulty of this work is not small, researchers have done in-depth study, after many discussions to find the difference between the two sets of equipment, and constantly adjust the design, after more than a month of hard work, reached a more ideal state. Yang Yongzhi, director of system design, fuel design, introduced this model of fuel system is also a new development, in order to stick the four fuel tanks on both sides of the short wing, to ensure that the oil does not diminish the case, the shape of the tank to change the previous rectangle, Become irregular, not only that, the tank bulletproof explosion-proof standards are higher, they first used in the helicopter rubber tank, fuel tank pipeline greatly increased the complexity of the design process, the application of fluid simulation software to solve the problem Provided effective help. Yang Yongzhi said: "At first, also made mistakes, leading to the left when the fuel tank refueling, after re-design makes the oil balance.In order to task, the team colleagues are also spelled, Zhou Zuojun children just turned 1 year old, His wife and wife separated from each other, he often work overtime until midnight, once again unknowingly dry to the early morning. "The people know the strength of the room has a money Hsueshen, this time he and his colleagues in the model together to capture the cabin system Leave the key issue of mass-quality equipment. Qian Xuesen busy time to work late at night when two or three points, "though tired, but full of heart, the problem will therefore be overcome one by one."
