Major Progress and Achievements in 2013
Regarding the integration of aircraft engines, a 60 kg thrust rated turbojet engine has completed its first flight after finishing twin-engine joint test and aircraft engine compatibility experiments at the end of 2013. In terms of key technologies, a new type of high load mixed centrifugal compressor has been explored, key technology breakthroughs were achieved in high hub-to-tip ratio centrifugal compressor design, compact and high performance diffuser design, tandem impeller design and mixed centrifugal compressor interstage matching under limited dimension space. Based on the original flat film cooling experiment rig, an experiment rig for film cooled flat plate conjugate heat transfer has been established, on which coupled heat transfer experiments and temperature field measurements can be conducted. Tests on main electric heaters, infrared thermal imagers and the experimental phase design have been accomplished. Regarding low emission combustion with fuel staged multi-point injection based on diffusion/premixed staged coupling combustion, improvements of ignition / flameout characters post staged combustion on single head and tri-head test articles were studied. The primary pollutant emissions at medium pressure were also investigated. The results showed an improvement in the gas- oil ratio, a wider band in stable combustion. Pollutant emissions met the design requirements at the same time.
Regarding vehicle gas turbine structure design and systems integration, the distributed energy supply gas turbine, whose core-engine was mainly designed by our institute, has successfully completed 400 hours of demonstration under support of the 863 Program and was been accepted by the MOST in January 9, 2013, indicating the success of the first high-performance micro-turbine in China. The main direction program of knowledge innovation of CAS, research and validation of a gas turbine, was advanced by the completion of the final engineering design. Building on the success of a 4MW gas turbine overall program design with the AVIC 460 factory, a 4MW power turbine designed independently by our institute passed its design review and ranked at the domestic advanced level, which laid the foundations for the next stage of power turbine machining, testing and systems integration. In regards to platform construction, a high- speed centrifugal compressor test platform was completed early in the year, and passed the expert review in May 2013. Under the support of the 973 Program, the first clean combustion test rig for low heat value gas in the 800~1200kcal/m3 range has been established and has achieved stable combustion of the low heat value gas.
Altogether 53 papers and conference papers were published in 2013 including 8 indexed by SCI, and 21 by EI. 9 invention patents were applied for and 1 of them was authorized.
