Problems solved by technology
[0003] Under the experimental environmental conditions, there are still some difficulties in testing the characteristics of the fog field of the aero-engine nozzle, such as: due to the limited space in the laboratory, the large clamping device cannot adapt to the current laboratory environment due to its large footprint and heavy weight; Limited to the size of the protective cover, the movement of the PDA cannot meet the measurement of all downstream fog fields; most of the current clamping control devices cannot perform the 360° coaxial rotation of the nozzle required by the experiment

On the premise of guaranteeing successful conduction of the experiment, the novel nozzle clamping control device which is convenient to manufacture and machine, light and convenient to arrange, easy and convenient to use, capable of axially ascending and descending and coaxially rotating by 360 degrees by a large margin, and suitable for various nozzles is designed. The device has fine adjustment capacity for the clamping posture except for basic clamping and movement, and further has certain improvement and updating potential.
Description
technical field [0001] The invention relates to a nozzle clamping control device that can be used in the PDA experiment of nozzle atomization characteristics. The device can clamp the nozzle and realize a large axial lift and 360° coaxial rotation in a small space. Fine-tuning of nozzle clamping posture can be realized. The invention belongs to the technical field of nozzle atomization characteristic measurement. Background technique [0002] The development level of aero-engine technology is an important manifestation of a country's technology, industry and national defense strength. As an important part of aero-engine, fuel nozzle plays a vital role in the performance of aero-engine. Nozzle performance has a very important impact on ensuring normal fuel supply, starting performance, normal combustion of aero-engines, improving combustion efficiency, reducing pollutant emissions, reducing ablation of walls, and formation of smoke and carbon deposits. [0003] Under the e...
