Shenyang Liming Aero Engine (Group) Co., Ltd.
Shenyang Aero-Engine Factory
Shenyang Aero-engine Research Institute (SARI)

China's largest aero engine manufacturer, Liming, or Li-Ming, (meaning daybreak) is one of the most experienced aero-engine centers in China. Founded in 1954, Shenyang Liming Aero-Engine Group Corporation (Liming) is China's first jet-propelled aircraft engine manufacturer and one of the country's key development projects. Liming employs more than 10,000 people. The company's business scope includes production and maintenance of aircraft engines, outsourced non-aero components and fuel engines, as well as steel products.

Also known as the SEF (Shenyang Aero-Engine Factory), or just as The New Factory, it was set up on the basis of an old overhaul factory in 1954-57. The first product was the WP5 turbojet, a version of the Soviet Klimov VK-1F (Rolls-Royce Nene derivative) produced under licence from the USSR Production of the WP5 was achieved in June 1956. By 1957 the WP5A, based on the VK-1A, was in production, but in 1963, following increased demand to power the H-5, production was transferred to the Xian factory.

In 1956 the SADO (Shenyang Aero-Engine Design Office) was established, later being restyled 606 Shenyang Aeroengine Research Institute (SARI). This undertook the design of the first Chinese turbojet, the PF1A, based on the WP5 but smaller, and rated at 15.7 kN (3,527 lb st) to power the JJ-1 trainer. Design was complete in 1957, and the PF1A powered the prototype JJ-1 in July 1958, but later the requirement for the JJ-1 was dropped.

Liming Aero Engine Group started cooperation with the General Electric Co. in 1980. In March 2000 it was reported that China's Liming Aero Engine Group was to produce plane engines worth of US$ 150 million for the General Electric Co. This was the country's largest industrial cooperation project in this field with a foreign company. According to an agreement signed by the two sides in March, the Liming Aero Engine Group will produce 150 million US dollar-worth plane engines and parts of gas-fired engine for the General Electric Co. in three years. To do the job, the group located in this capital city of northeast China's Liaoning province will invest 200 million yuan ( about US$ 22 million) to upgrade technology and set up an advanced production line.

This state-owned company is currently in the process of transforming itself into a lean enterprise. Liming's previous product development process was characterized by a serial workflow based on the transmission of paper documents, a distributed and ineffectively integrated personnel organization and an out-of-date, non-collaborative information technology system. In the spirit of the lean initiative, Liming management has been studying the strategies of leading international defense and aviation corporations. They have also established specific goals within the lean initiative. These include better flow of information through the enterprise, optimized use of manufacturing resources, lower product development costs, a shorter product development cycle and improved product quality.

On March 29, 2005 UGS, a leading global provider of product lifecycle management (PLM) software and services, and Shenyang Liming Aero-Engine Group Corporation (Liming) announced that Liming expects to increase its production capacity by 20 percent to 50 percent by using UGS' Teamcenter« PLM solution, the de facto standard for PLM, for its manufacturing processes. Liming will use Teamcenter in the production process to enable it to re-use production data for future product development and to enhance quality and efficiency. Liming currently relies on a high level of manual work, resulting in a slow and inconsistent process. UGS' Teamcenter will provide Liming the product knowledge management and collaboration infrastructure to bring together its wealth of product and design information in an open, collaborative environment. The solution will enable, for instance, the design work done by Shenyang Aero Engine Research Center to be integrated much more closely with the production work, handled by Liming.

Shenyang Liming Aero-Engine Group Corporation became an approved Rolls-Royce plc supplier in 2002 and produces heat shield rings for the BR700 series. On 19 August 2010 AVIC Shenyang Liming Aero-Engine (Group) Corporation Ltd., announced that its international engine unit came into operation. The newborn unit, set up with the Shenyang Hunnan New District Export Processing Zone, will make Rolls-Royce aircraft engines. Liming Aero-Engine Group invested CNY 434 million in total to build the production line for the Rolls-Royce project.

In June 2009 diversified industrial manufacturer Eaton Corporation announced the signing of a six-year supply agreement with Shenyang Liming Aero-Engine Group Corporation, which is fully owned by Aviation Industry Corporation, or AVIC, China's national aircraft manufacturer. Under this agreement, Shenyang Liming will supply Eaton with components used in fuel-system applications. This contract with Shenyang Liming will further strengthen Eaton's sourcing presence in China with AVIC International. AVIC will now support Eaton and its customers on a wide range of platforms.

GE Liming is a $18.9 million USD joint venture formed on August 28, 2003 between GE Energy (51%) and Shenyang Liming Aero-Engine Company, Ltd. (49%), one of China's primary manufacturers of aero-derivative gas turbines and jet engines. The joint venture manufactures combustion components, buckets and nozzles to contribute to the assembly of GE's Frame 9FA and 9E gas turbines in China.

In August 2005 GE Energy hosted a joint grand opening for new facilities in Shenyang built to support two of the company's joint ventures: Shenyang GE Liming Gas Turbine Component Co. Ltd. (GE Liming) and GE Shenyang Turbomachinery Technology Co. Ltd. (GESTT). The two joint ventures represent a combined investment of $32.6 million USD in China's northeast region. GE fulfilled its commitment on gas turbine technology transfer since the beginning of China's Gas Turbine Power Plants Construction Project. With the first gas turbine assembly completed on time, GE has become the first to deliver a locally assembled gas turbine to the China market, and also the first to deliver the locally manufactured combustion component in China.

In July 2007, GE Aviation said it was looking to have the CF34-10A engines assembled in China, but to begin with the engines would all be assembled at GE's plant in Durham, North Carolina. The CF34-10A powers the 90-seat ARJ21-700. GE entered negotiations with Shenyang Liming Aero Engine Group that could lead to an arrangement to produce GE CF34-10A turbofans for the ARJ21 in China. Talks centered on granting responsibility for "some of the assembly activities and final testing," possibly by 2015.
