Projects and Major Achievements

Space experiment system technology
 In terms of the development and delivery of the Combustion Science Experimental System (CSES) of the Combustion Science Rack aboard the China Space Station, an authentic product has been designed, and the functional performance test, mechanical test, thermal cycle test, experienced test and ergonomic evaluation test were carried out. After being delivered to the General Department of Space Application Systems, CSES underwent extensive testing at the Tianjin Assembly Plant and Hainan launch site. Subsequently, CSES was launched into orbit along with the Mengtian Lab Module on October 31, 2022, and the first in-orbit power supply check and functional performance test were then completed, which indicates that the experimental system is in normal condition and meets the expectations.
In the development of space inorganic curing capsules, the space heating and curing experiment of fiber-reinforced inorganic composites was carried out. It's to verify the technology of material forming in microgravity and high vacuum environment preliminarily.
 
 Intelligent patrol technology
In the realm of self-organizing networked patrol flight systems, we've set our sights on the demands of future unmanned systems and honed in on the cutting-edge benefits of technologies like edge computing, stealth aerodynamics, and active control. We've actively sought out and presented proposals for related research topics, successfully securing approval for key projects from the institute.
We've organized a range of pioneering studies and innovations based on our patrol flight platform. We've recently completed an all-encompassing evaluation of a particular product, conquering key technical challenges such as the integration of avionics products, miniaturization of IMU navigation systems, and creating lightweight deep learning algorithms. We've manufactured a prototype, and currently, we're carrying out ground integration testing and flight validation preparation.
 
Underlying technology
In the aspect of intelligent structure and manufacturing technology, the research on the preparation process of film sensor applied to intelligent main bearing and the development of capacitive grating displacement sensor applied to actuating shaft were carried out. At present, the trial production of thin film sensors and measurement experiments of capacitive displacement sensors have been completed, achieving displacement measurement with a precision of 0.1 mm.
 
In terms of composite technology, the structural design and aerodynamic load simulation of the aero-engine compressor stator which is made by composite and based on the metal skeleton were completed, and the structural design and aerodynamic simulation of the compressor rotor were carried out, and the relevant design methods were formed preliminarily.
 
In terms of measurement and testing technology, three prototypes of temperature field/strain field simultaneous measurement probes, including a binocular micro-vision system integrated probe based on the active light source, a non-contact focusable adaptive multi-field synchronous integrated probe, and a multi-channel integrated probe based on the fiber bundle, have been developed. The technology for calibrating the temperature and strain measurements for hot-end components was proposed. Simultaneously, a system for calibrating temperature and strain was created that solves the main technical issues with temperature field calibration for hot-end components. The accuracy of temperature measurement was increased by combining with the correction of emissivity in the study for measuring the temperature of the blade surface using radiation thermometry. The assessment preparation for key milestones and the timeline of projects is currently underway.
