The Sino-Russian joint long-range passenger aircraft is a major strategic cooperation project between China and Russia in the field of high-tech cooperation. Its progress has been closely watched by all walks of life.
Recently, China National Machinery Group's China Second Heavy Machinery Group Co., Ltd. Wanhang Company (hereinafter referred to as 'Dualen Wanhang Company') successfully completed the localization of the key forgings of the main landing gear of the C919 large aircraft. CR929 wide-body passenger aircraft landing gear main outer tube forging trial production work.
The forging is the largest and heaviest key bearing product on the CR929 aircraft. It is a test piece for the preliminary design of AVIC Landing Gear Company. Although the company has experience in the production of similar products, the landing gear product weighs 13 tons, complex structure and high control precision, put forward higher requirements for trial production. The two-way Wanhang civil aircraft project team after a month of technical research, reasonable planning, design, implementation of all aspects of the trial system And on-site service ensured the successful trial production of the product.
The successful trial production of the CR929 wide-body passenger aircraft from the outer tube forgings has enabled Erwan Wanhang to move towards a new journey of larger, heavier and more difficult landing gear forgings. In the future, the company will build The world-class aviation die forgings company aims to continue to strive for the independent guarantee of China's large aviation die forgings.
