礦山空氣調節系統.人行道用葉片調風門.非減壓的風扇To meet the needs for wider surge margin of the turbofan engine, a new model was developed to predict the characteristics of the fan / high pressure compressor and turbine in this thesis. several ways, including, variable inlet guide vanes of the fan, variable guide vanes of the high pressure compressor, the variable inlet area ratio of the mixer and the nozzle areas, were presented to enlarge the surge margin of the turbofan engine. meanwhile, a method of combined variable geometries for optimizing controls of inlet guide vanes of the fan, guide vanes and the first two stators of high pressure compressor, area ratio of mixer and noz zle areas was established
為了滿足下一代作戰飛機對推進系統的性能和穩定性要求,本文建立了壓縮系統特性和渦輪特性的新模型,並分別採用改變渦扇發動機風扇進口導流葉片、壓氣機導流葉片和前兩級靜葉片、混合室進口處內、外涵面積比和尾噴管面積,研究了其對發動機性能和穩定性的影響,進而得出了渦扇發動機變幾何擴穩的方法,為發動機變幾何擴穩研究打下理論基礎。The former one is a product of the pressure pulsation resulting from the fan blade periodically cutting the air, with the blade passing frequency as its base frequency and accompanied by higher harmonics. the wide - band turbulent noise is formed when the rotating fan forces the surrounding air to produce turbulent throw - outs and results in gas thickening and thinning processes
旋轉噪聲是由於風扇的葉片周期性地切割空氣,引起空氣的壓力脈動產生的,以葉片通過頻率為基頻,並伴有高次諧波。湍流噪聲是由於風扇運動導致的周圍空氣發生湍流脫體,使空氣發生擾動,形成氣體的壓縮與稀疏過程而形成的,是一個寬頻帶噪聲。Coupled with the curved heat exchanger, the york cooling king is also designed to operate at the lowest noise level - 29dba at low speed fan
