1. AVIC Dynamic Control (000738): The company has become the only research, production and testing base for aircraft engine control systems in China. Its main business is positioned as the development and production of aircraft engine control systems. At the same time, it has different Engaged in the maintenance business of the company's products to a certain extent, it has leading advantages in terms of status, experience and popularity in this professional field; in addition, due to the particularity of the aviation market, the technical development of the company's products basically depends on the needs of engine manufacturers. Based on We have established long-term fixed-point supporting cooperative relationships with domestic complete aircraft engine manufacturers. From January to June 2012, the company's engine control system and components business achieved operating income of 714.299 million yuan, a year-on-year increase of 4.55%.
2. Chengfa Technology (600391): The company is mainly engaged in the main parts of aero engines and gas turbines, and has a firm development goal of “becoming a world-class aero engine parts supplier”. In addition to major international aero-engine companies such as GE, RR, and P&W, our partners have also developed new customers such as Snecma, Honeywell, Siemens, and Schlumberger. Through the joint efforts of all the company's employees, the company's foreign trade aviation product revenue reached a new high in 2011, which was the first time the company's foreign trade industry exceeded the US$100 million mark after the financial crisis.

3. Shandong Mining Machinery (002526): In November 2012, the company conducted preliminary research and development and trial production of UAV engine-related technologies and products, and has now completed a small turbojet engine experiment Trial production of the prototype; this project is now only in the trial production stage of early technology, production, and technology. Up to now, no large-scale investment has been made, and the investment plan for the project has not been formulated; the company has now mastered but only the experimental prototype machine Related technologies for engine manufacturing.
4. Steel Research Gaona (300034): The company’s main product, high-temperature alloys, is a key material for manufacturing hot-end components of aerospace engines and can be used in aerospace engines, ground gas turbines, generator sets and other power devices core components. The company's deformed high-temperature alloy products are mainly small batches and complex structures. Some of the deformed high-temperature alloy products produced by the company are products for which some partners do not have the production technology. At the same time, the production line is highly flexible and can easily meet customers' customized needs. In terms of new high-temperature alloy material series products, the company's powdered high-temperature alloy products, ODS alloys and Ti-Al intermetallic compounds are the first to be developed and produced in China. Some products are exclusively supplied, and the company's technical reserves in this field are in a leading position in the country. .
