Research demand drives equipment upgrade: high resolution, high precision, macro docking for high temperature, high speed, micron level requirements

Turbine blade film cooling technology is a core research direction in the field of thermal protection for aircraft engines. In the past, the team mainly measured aerodynamic performance through a schlieren system, but was unable to synchronously obtain data on the distribution of blade surface cooling efficiency. With the upgrading of experimental requirements, the problems of insufficient accuracy and delayed response of traditional contact sensors in high temperature and high-speed environments have become prominent.

The research leader stated that the small temperature difference at the edge of the cooling hole may directly affect the blade life, and the lack of tools that can achieve non-contact, high-resolution temperature measurement under dynamic conditions has become a key challenge restricting the deepening of research. As the research deepened, the team realized the need for a high-precision macro infrared thermal imager to capture the temperature changes on the surface of the blade or flat plate after being cooled by airflow.

Among numerous brands and models, the team ultimately chose the Gewu Youxin high-precision macro infrared thermal imager X640F150UM95. As a domestically produced high-precision infrared thermal imager, the Gewu Youxin high-precision macro infrared thermal imager X640F150UM95 has good image effects, accurate temperature measurement, and stable performance. It has high resolution, high precision, and macro imaging capabilities, and can accurately capture temperature changes in small areas of the blade surface, meeting the strict requirements for temperature accuracy and imaging distance in experiments.

The researchers stated that the Gewu Youxin high-precision macro infrared thermal imager X640F150UM95 is of great benefit to our project. In practical use, the camera is installed on the equipped camera bracket, and the focus of the camera can be manually adjusted. After adjustment, subsequent experiments can be directly imaged by switching the power supply. The camera provides fast imaging speed, suitable for the frequent and efficient data acquisition needs in scientific research projects. The imaging clarity of the equipment is very high, and the details are presented clearly, greatly improving the reliability of scientific research data. ”

Compared with traditional devices, the X640F150UM95 thermal imager can provide more delicate temperature distribution maps, support real-time imaging and data acquisition, and perform particularly well in high-speed and high-temperature environments. Its non-contact measurement method is not only safe and efficient, but also can reveal the unevenness of blade surface temperature, providing key data for analyzing cooling efficiency.

With the help of the macro thermal imager X640F150UM95, the team captured the temperature gradient in small areas such as the edge of the blade cooling hole, and identified local overheating phenomena that are difficult to detect with traditional sensors. By comparing data from different cooling structures, the team identified the shortcomings of the existing cooling hole layout and quickly iterated improvement solutions, significantly improving the cooling efficiency of the blades.
