Research Field
Facing the major needs of future intelligent patrol technology, aerospace new structure and new material technology, we carry out follow-up combustion science on-orbit upgrade and operation and maintenance, strive to build the main battle ground of patrol flight, innovate and break through basic technologies such as intelligent structure and manufacturing, composite materials, measurement and testing.
Team Building
There are 22 employees, including 2 senior posts and 3 deputy senior staff; 2 postdoctoral fellows in the station; 54 graduate students.
Project and Major Achievement
Aerospace experiment system technology We carried out on-orbit testing and operation and maintenance research of the space station combustion science experiment system, completed a total of 8 on-orbit tests and experiments throughout the year, and successfully ignited a total of 5 times, and observed for the first time the extinguishing process of the diffuse flame and part of the premixed flame under microgravity conditions in the process of extinguishing the unique opening and hook-like flame structure; One set of coarse filters for combustion science experiment system was developed and followed by the TZ-6 mission. In the TZ-7 mission, a total of 9 sets of oxidant cylinders, inert cylinders and other application materials and 2 sets of goods package products were completed.
Intelligent cruising technology
Integration and ground co-testing of high-speed unmanned cruising aircraft have been finalized, along with the flight validation of functional performance metrics, including multi-drone intelligent networking and cooperative flight maneuvers for low-speed drones, as well as altitude limits and endurance for high-speed unmanned cruising aircraft. Throughout the year, a total of 20 flight tests were executed, achieving breakthroughs in key technologies such as algorithms for intelligent cooperative formation of multiple drones, highprecision integrated inertial navigation systems, cost-effective structural modular designs, and cost-effective avionic modular designs. The comprehensive design, aerodynamic modeling and simulation, and structural prototype design and review for a box-launched, folding-wing high-speed cruise platform have been completed, marking the transition to the prototype production phase.
Basic technology
In terms of non-contact measurement, the test and optimization of three kinds of probes (binocular microvision system integrated probe based on active light source, non-contact adjustable focus adaptive multi-field synchronous integrated probe, and multi-channel integrated probe based on optical fiber bundle) were emphatically carried out, as well as the verification and optimization of the thermal protection scheme of the probe, the optimal design of the temperature/strain calibration device, the research on the test verification technology of the stress/temperature field static/rotor component of the hot end components, the research on the conversion simulation technology of the non-uniform temperature field and the stress field, and the improvement of the multispectral radiation temperature measurement system and its calibration test.
Composite blade co-curing technology
A composite compressor stator blade based on metal skeleton was developed, which achieved the goal of weight reduction and high density of fiber volume content. We carried out the pneumatic blowing test of the stator blade sample to evaluate its high-cycle fatigue performance, and the test acceptance preparation of the project is currently being carried out.
Patent and Paper
This year, a total of 3 academic papers were published; 7 invention patents were applied for and 3 invention patent authorizations were obtained.
