The Scientific Platform for Aero-Propulsion and Multiphase Flow Research (SAM) focuses on the fundamental research of aviation combustion machinery and new energy utilization, multiphase flow and turbulent combustion, and micro-nano fluid mechanics. It dedicates to overcoming scientific challenges in specific research fields such as micro-nano particle emission detection of aero-engine exhaust, general aviation and UAV engines development, new energy and nanomaterials, and intelligent diagnosis and prediction. The labs have high-precision instruments such as low-temperature controllable humidity micro-nano environmental Scanning Electron Microscopy (eSEM), movable ice core test systems (PINE). Four scientific research sub-platforms have been built, including micro-and nano-scale particle detection and characterization, general aviation and unmanned aerial vehicle (UAV) power test, new energy and nano materials, and intelligent diagnosis and prediction, to serve the research of aero-engine emission detection, aviation power equipment development, and intelligent diagnosis. Efforts have been channeled to the building of platforms at ZFAU including micro-and nano-scale particle detection and characterization center, unmanned general aviation and non-conventional aviation discipline, major public platform for small high-altitude environment simulation, and intelligent diagnosis and prediction platform.

SUB-PLATFORMS
1. Micro & nano-scale particle detection and characterization clean room
Self-developed wide-temperature nanoparticle number detection prototype
The platform focuses on the detection and characterization of airborne particle emissions at micron and nano-scales, mainly facing the analysis of high-temperature pollution sources, atmospheric environmental monitoring, aviation wake cloud emissions, and atmospheric ice nucleation mechanism. The experimental platform has been purchased or built, including low-temperature controllable humidity micro-nano environmental Scanning Electron Microscopy (eSEM), mobile ice core test system ( PINE ), and other high precision instruments. With the current experiment equipment and technology, the first international wide-temperature PM2.5 number concentration detector was developed successfully. The number of nanoparticles detection has been expanded from room temperature to high temperature, promoting the development of high-temperature particle multiphase flow theory. At the same time, the instrument is applicable in the airworthiness certification of aero-engines and large domestic aircraft. The particle detection prototype developed by the platform has been successfully applied in AECC Commercial Aircraft Engine Co.,LTD, China Atomic Energy Research Institute, Dongfeng Motor, Tsinghua University, and Peking University. The instrument won the Sino-French team cooperation and innovation R&D award, the Asian Aerosol Conference Excellence Report Award, etc.
