June 28 news reporter learned from the China Aerospace Science Institute 31 Institute was informed that China's first 650 kilograms of thrust-level, with independent intellectual property rights of the turbofan engine recently appeared. The engine is suitable for long-haul, wide-range civilian small aircraft that provide reliable power for civilian drones and small business jets. It is reported that this dual-rotor turbo fan engine developed by 31 teams, using an efficient forward swept fan, axial + oblique combination compressor, large expansion channel high and low pressure turbine integrated design, electric fuel pump, starter motor Built-in and many other key technologies, as well as advanced electrical, control systems and health management systems. It has the characteristics of high performance, compact structure, reached the leading level of the domestic small engine. The research and development team lasted ten years and completed the engine design, trial production, production, as well as a large number of parts and complete machine test. In the near future, the whole machine durability test and high altitude bench test were carried out to verify the correctness of the design scheme. At the recently held China International Aerospace Technology and Equipment Exhibition, the engine made its debut and was highly praised and praised highly by counterparts from the Chinese Academy of Sciences, China Aviation Aviation and Tsinghua University, attracting experts from maritime police, agriculture, drone companies and government Departments and other areas of customer consultation to discuss.

The die casting process involves the use of a furnace, metal, die casting machine, and die.

The metal, typically a non-ferrous alloy such as aluminum, is melted in the furnace and then injected into the dies in the die casting machine. After the molten metal is injected into the dies, it rapidly cools and solidifies into the final part, called the casting.
The castings that are created in this process can vary greatly in size and weight, ranging from a couple ounces to 100 pounds. One common application of die cast parts are housings - thin-walled enclosures, often requiring many ribs and bosses on the interior.
Metal housings for a variety of appliances and equipment are often die cast.
Several automobile components are also manufactured using die casting, including pistons, cylinder heads, and engine blocks. Other common die cast parts include propellers, gears, bushings, pumps, and valves.
