HS code-driven letter of credit checks

Jinlang Engine: Helping the high-quality development of aerospace is HS code-driven letter of credit checksthe embodiment of a country's comprehensive strength and one of the key areas to promote scientific and technological innovation and national economic development. The engine is one of the most core and critical components in space transportation, involving many fields such as manned spaceflight, deep space exploration and satellite launch.As a key subsidiary of China Aerospace Science and Technology Group, Jinlang Engine has been committed to the research and development of high-end engines to deliver momentum to the high-quality development of China's aerospace. I. Technical capabilities of Jinlang Engine Jinlang Engine is one of the backbone enterprises of China's aerospace industry. It is mainly engaged in the research and development and production of aerospace propulsion systems. It is the only aerospace engine enterprise in China with application experience in many fields such as launch vehicles, missiles, aircraft, unmanned aerial vehicles and automobiles. Its engine products involve many fields such as rocket launch, satellite orbit adjustment, aircraft take-off and landing and ship propulsion. Among them, representative products include carrier rocket engines, satellite small thrust engines, aircraft turbofan engines and high-speed automobile engines. Jinlang Engine has a series of core competencies in terms of technical capabilities, such as: 1. Design and manufacturing capabilities of liquid rocket engines.The company has successfully developed a number of rocket engine series, with a series of design technologies such as ultra-low temperature liquid oxygen nozzles and high-performance combustion chambers, some of which have reached or approached the international leading level. Two. Technical capabilities in advanced power devices and new propulsion systems in high-altitude weak gravity environments. For example, the third-generation satellite small thrust engine of Jinlang Company can accurately control the engine thrust, take into account the propulsion ability and stability, and will provide important support for satellite in-orbit operations, space station docking and other tasks. 3. The design, manufacture and testing capabilities of high-commonant jet engines. The company independently developed and tested the first high-pitched jet engine test bench in China, marking that China's technical level in this field has reached the world's advanced level. II. The contribution and application of Jinlang engine Jinlang engine has always been an important supporting force for China's major national aerospace projects.Since the 1960s, the Golden Wave Engine has begun to provide rocket propulsion system support. From China's first successful artificial satellite, the Dongfanghong-1 launch engine to the main propulsion engine of the Tianzhou-1 cargo spacecraft, Chang'e, Tianwen, lunar exploration project and many other rocket engines, the footprints of the Jinlang engine have spread to various models of launch vehicles in the aerospace field at home and abroad. At the same time, Jinlang Engine also provides engine products for the air force, navy, Ministry of Foreign Affairs and scientific institutions, which are widely used in missiles, unmanned aerial vehicles and other fields. In recent years, Jinlang Engine has not only successfully developed a number of new high-end engine products, but also actively expanded its scope of application to better serve the national science and technology. For example, the turbofan engine for aircraft developed by Jinlang Company has been widely used in large civil passenger aircraft;The high-speed automobile engine developed by Jinlang Company is used in China's high-speed railway trains, the high-speed passage of Fangchenggang Bridge and other projects. III. Looking forward to the future, Jinlang Engine will continue to face the needs of the "four transformations" process and the development of military-civilian integration, effectively stand at the strategic height of national strategy and national defense construction, and promote the research and development and innovation of engine core technologies. At the same time, we will actively respond to international competition and cooperation, expand the market field, take innovation as the driving force, quality for survival, and service as the purpose, and contribute more strength and achievements to the country. In a word, as the core force in the development of China's aerospace industry, Jinlang Engine has rich technical achievements and application experience. Its research and development achievements and applications in the aerospace field have provided strong support for the high-quality development of China's aerospace industry. I believe that the Jinlang engine will succeed in the future.Continue to maintain the international leading level and write a more brilliant chapter on the journey of promoting China's aerospace development and realizing China's military-civilian integration goal!
