Projects and Major Achievements

In the development of experiment system of space station combustion cabinet , the development of electrical part products have been carried out and an important breakthrough has been achieved. The detailed design and evaluation of electricity, mechanism, heat, six properties, and ergonomics at the preliminary stage has been completed. The special design and evaluation of shelf components, component selection, raw material selection, etc. at the preliminary stage are completed. The preliminary electrical parts have already completed integration and debugging, passed the EMC test and the practice test. The preliminary electrical parts have been delivered to superior corresponding department and passed the system interconnection test in cooperation with them. The development of identification parts is ongoing. In the development of wide rotating composite fan blade, precision subtractive processing based on additive manufacturing of fan blade skeleton is completed and a lightweight metal skeleton is successfully formed. The research on the composite braiding process of blades based on the metal skeleton is carried out and a typical composite braided structure has passed impact strength test; the development of the composite blisk and the balance test of the blisk are completed.

In the aspect of hybrid additive manufacturing technology, the compressive properties of the novel lattice structure are improved by more than 120% compared to the traditional lattice structure by optimizing the shape factors of the lattice structure. The evolution of temperature and thermal stress during the additive manufacturing process are explored, and the thin-walled parts of ramjet are successfully manufactured. It is expected to achieve the goal of reducing weight, increasing efficiency and prolonging life by carrying out the research on multi-alloy system and multi-function integrated design and manufacturing technology for the core parts of large ship like propeller. In the aspect of research of basic theory and key technology of novel heatmanagement materials, a new material, the vertical-grown-graphene, is developed. The thermal conductivity of such material reaches 53.5 W/m.K, which is about 10 times higher than that of the traditional products. At the same time, the thermal contact resistance is reduced significantly. A multiscale catalyst thermal management strategy was designed to solve the problem of sintering of catalyst particles at high temperature, which slowed down the sintering process at least three times.

In the aspect of combustion chemistry, the iso-propylbenzene laminar premixed flame under the pressure of 30 Torr, equivalence ration of 0.45 ~ 1.58, is studied using photon ionization molecular beam mass spectrometer. The benzyl alcohol pyrolysis experiment is completed. The acetylene high-pressure oxidation experiment is carried out using HP-JSR. The PIV research is started. The amorphous film is made and its catalysitic effect is researched. The VOCs catalystic abasement study is completed. The ground-based experimental apparatus drop tower and the corresponding remote ignitor in cabin are built. The normal gravity continuous PIV measuring equipment is built. The flow field diagnostics of acetylene flame is completed.
