Chinese firm delivers self‑developed core casting for world's most powerful onshore wind turbine_我的网站
一 | 1月14日：混合动力飞行器宣布将退役其原型“空中着陆器10”，这意味着世界上最长的飞艇将不会重返天空。
二 | 空军10号原型混合动力飞行器的斯蒂芬·麦格伦南说，它将利用飞船上的资源建造第一批生产级的空军10号。
The core castings for the world's most powerful onshore wind turbine in terms of single‑unit capacity have recently been delivered by a Chinese company, marking a technological breakthrough in the large‑megawatt onshore wind power castings, domestic news portal stdaily.com affiliated with Science and Technology Daily reported on Wednesday.
Independently developed by Dalian Huarui Heavy Industry Group Co., Ltd. (DHHI), the delivered components include the bearing housing and base castings for 15 MW doubly fed onshore wind turbines. The components need to bear the huge gravity, wind loads and alternating loads transmitted from the blades and hub, and transfer the loads to the generator, ensuring steady rotation of the main shaft.
The products passed all customer inspections and assessments in one go and were officially delivery, stdaily.com reported.
Adopting an advanced modular design, the turbine components delivered can support flexible power adjustment ranging from 13 MW to 16 MW, enabling adaptive operation to varying and complex wind conditions across diverse regions, the report said.
The turbine's rotor diameter ranges from 240 meters to 260 meters, and are compatible with tower heights of 135 meters to 190 meters, delivering a maximum swept area of 53,000 square meters, roughly 8 standard football pitchs (105m×68m). This places the unit's overall performance among the world's top-tier.
Such super-large castings place extremely high demand on material properties, casting processes, dimensional accuracy and internal quality. The successful validation and delivery of the products therefore demonstrate the research and development, as well as manufacturing capabilities in super‑large wind power castings, stdaily.com reported.

。他还表示，该公司正在寻找关键供应商。原型飞艇采用氦气动力，支持垂直起飞和着陆，无需使用停机坪跑道滑雪。飞艇采用空气静压和气动升力飞行，由四个柴油发动机驱动的导管螺旋桨驱动。
三 | 这也意味着302英尺（约92米）长的飞机，飞艇混合结束。这艘飞艇只飞了六次，它的试验历史又短又艰辛。飞艇在第二次着陆飞行中损坏了。在另一次飞行中，飞艇松动并泄漏，造成人员受伤。
