Strong in product strength
In the laboratory of Rongtong Aero-engine Technology Co., Ltd, the company's self-developed high-end turbojet engine is undergoing ignition operation experiments, and the R&D personnel are paying close attention to the test status.
"This engine speed can reach up to 40,000 rpm, close to three times that of a large aviation engine, and due to its small size, light weight and low cost, it can power high-speed UAVs and be more widely used in civil low-altitude economic fields." Rongtong Air Development Control Center Manager Wu Bin said.
Since its establishment in 2022, Rongtong Aviation Development has been anchored in the small aircraft engine track, and now has dozens of products in two series of turbine and piston, which is one of the enterprises with the most complete product spectrum and the most applications in the field of domestic micro-small aircraft engines.
Product performance is relatively leading in the country, and can operate in extremely cold and oxygen-deficient environments. "A certain type of aviation piston engine product adopts high-efficiency atomization technology, adapting to the marine use environment, especially its fuel consumption reaches the domestic leading level of the same class of engine, which can be applied to the sea with a small vertical take-off and landing fixed-wing reconnaissance, agriculture, forestry, plant protection, emergency rescue, scientific research and other unmanned aerial vehicles." Dr. Chang Guoqiang, deputy general manager of Rongtong AeroDevice, cited an example.
In the field of miniaturized and lightweight turbojet engines, Nanjing Tuxuan Technology Co., Ltd. has a number of key core technologies, such as impeller system design technology, high excitation high-power generator design technology, and other key core technologies, and has a leading edge in power generation, miniaturization, integration, etc., which has reached the domestic advanced level.
"The 30kW-200kW high-power turbojet generator system we have developed can provide high-power, small-size and lightweight power supply products for airborne, vehicle-mounted, mining and construction machinery." The relevant person in charge of Tuxuan Technology introduced.
Commercial aviation is also a new track that Nanjing is actively laying out. Ltd. production workshop, engineers are stepping up the assembly and debugging of satellite portable station products. And in the company's showroom displays a variety of satellite communication terminal equipment, the height of the machine from forty to fifty millimeters to forty to fifty centimeters, than the traditional phased array equipment to reduce the weight of 80%, power consumption reduced by 70%.
Enhancing the hard power of products, a thousand sails compete for the aerospace dream. The JC-S2000 hangar developed by AVIC Jincheng Unmanned Systems Co., Ltd. is in the leading position in the industry as the autopilot capability of the UAV reaches L4 level, which can automatically perform almost all routine tasks and return data without human intervention.
In addition, Kerrystar Information Technology (Nanjing) Co., Ltd. can formulate satellite communication network systems of different scales according to users' needs, and the series of products have been widely used in many fields, such as transportation, emergency communication, and IoT monitoring.
