Danfoss Motor – Motor: Increased Temperature Capacity
Nanjing University of Science and Technology held a press conference on the 21st. The team of Professor Chen Guang developed a high-temperature PST titanium-aluminum single crystal, which increased the temperature-bearing capacity by 150 to 250 °C, which is a major breakthrough in motor materials. According to reports, the main material of China’s motor blades is nickel-based single crystal superalloy, which is a new generation of alloys with a temperature increase of 25 to 30 °C. The aero motor is known as the heart of the aircraft, and the temperature-bearing capacity of its core components directly determines the performance of the motor.
Shen Wan Hongyuan Research believes that with the establishment of Air China and the acceleration of the “two-machine special project”, it is expected that the motor research and development is expected to receive 10 billion special subsidies for 10 years, and the global aerospace and gas turbine motor superalloy and blade market space is expected to reach 175 billion yuan. /year.
The Danfoss Motor stated that the motor research and development work is characterized by technical difficulty, cost and long cycle. The motor has a decisive influence on the performance of the aircraft and the success and progress of the aircraft development, and the motor technology has good military and civilian use. Characteristics are of great significance to national defense and the national economy. Therefore, several countries in the world that can independently develop advanced aero motors will give priority to the development of aero-motors as a national policy, classify motor technology as a key technology for the country and national defense, and give a large amount of investment to ensure that the motor is relatively independent and leading development, and strictly prohibited. Export of key technologies. Some aero-motord industrial countries have also developed major technological development plans to establish the ability to independently develop or participate in international cooperation in the development of advanced aero motors.
In order to meet the requirements of various aircraft developments in the 21st century, aviation developed countries have implemented a new turbine motor technology development plan since the late 1980s. The goal is to master the technology that doubles the motor capacity from 2005 to 2008. The results achieved have been successfully applied to the improvement of some in-service motors and the development of new models, and are currently in the verification phase of the final goal. In view of the successful implementation of the plan and the important role of the motor in aviation development, some countries have developed further motor technology development plans. The new plan will continue to increase its capacity while placing greater emphasis on cost reduction. The goal is to increase the economic affordability measured by the ratio of motor capacity (push-to-weight ratio/fuel consumption rate) to full-life cost from 2006 to 2015. Times. In the field of hypersonic propulsion, the focus is on the development of supersonic combustion ramjet motors and pulse detonation wave motors. Other new concept motors and new energy motors are also being explored, such as micro-electromechanical-based micro-UAV ultra-micro turbine motors and multi-electric motors, as well as liquid hydrogen fuel, fuel cells, solar and microwave energy, etc. New energy power.
