Explore innovative development of aero engine experimental platform and equipment

The experiment platform of the aeroengine badly needs to develope in the direction of the overall supporting, the database system management and the engineering practice. Experimental means such as the water, electricity and gas systems which support the operation of equipment, and multiple sets of engine components （the compressor, the turbine, the combustion chamber, the structural strength etc.） which support the experimental study of the engine also badly needs to improve in the direction of comprehensive monitoring and system integration to meet the needs of high efficient experiment and management. The experiment platform can make the experimental data and the experimental process be shared in different places in real time. Improving the collaborative ability of design and experiment, improving the automatic level of the experiment and so on all need the computer, the network and the professional and matching application system to support so as to guarantee the security, the stability and the reliability of the experiment, and reduce the risk of the experiment. This paper mainly discusses the main innovative exploration of experimental platform and equipment development about the current aeroengine.
