【文章內(nèi)容簡介】 llowed by the engine operating temperature also , temperature increase is not unlimited, it is subject to the bustion chamber (flame tube should be more precisely the material properties of the high temperature limit), so aeroengine designers began to consider the high thrustweight ratio of aircraft engines, in recent years as Rising fuel prices and reduce fuel consumption rate of the voice is also the development of high thrustweight ratio of air to launch imperative. In this thesis, aircraft engine materials and thermal efficiency analysis, the use of thermodynamics, theoretical mechanics, material mechanics theory, from the macro, micro, analyzing parative experimental data, have the following conclusions:GH150 thrustweight ratio of materials to improve the maximum。 improve aircraft engine bustion chamber temperature can effectively improve the efficiency of aviation engines。 temperature and density, the higher the ratio of material properties can effectively improve the thermal efficiency of the engine。The temperature of the burning chamber studies and in the materials used in fire extinguishers should be the main consideration dome region and the subsequent first film segment。 efficiency of the bustionefficiency, Carlo cycle efficiency, the efficiency of the energy loss of three factors Decided to remain unchanged in the other two factors to improve the situation for any one of the factors corresponding increase thermal efficiency.Keyword：Aircraft engineMaterialratioCreepLasting PropertiesAnalysis of thermal efficiencyThrustweight performanceTurbofanCombustionefficiencyFlame tube wall temperatureCombustion chamber1 引言 .............................................................. 4 概述 ......................................................... 4 本文要處理的征詢題 ............................................. 62 航空發(fā)動機原理簡介 ................................................ 6 航空發(fā)動機分類 ............................................... 6 渦輪風扇發(fā)動機原理 ........................................... 8 渦輪風扇發(fā)動機分類 ..................................... 8 渦扇發(fā)動機理論和特點 ................................... 93 航空發(fā)動機的熱效分析 .............................................. 9 燃料的燃燒效率 .............................................. 10 燃燒反響速率 .......................................... 10 燃燒效率的計算 ......................................... 11 溫度與平均動能的關(guān)系 .
