摘要
通过给定航空发动机非安装特性和飞机基本气动特性,建立了用于计算发动机安装推力和飞机基本飞行性能的数学模型,并进行了发动机推力变化对飞机基本飞行性能影响的敏感性分析。分析结果表明,发动机推力变化对飞机最小平飞马赫数影响的敏感度很小,对最大爬升率影响的敏感度较大,对飞机最大平飞马赫数和实用升限的影响由发动机的具体状态和推力变化趋势决定。
The mathem（aical model was established for eroaluating the （wroengine installed thrust performance and the basic flight peformance by the non-installed characteristics and the aireraft aerodynamic characteristics given. The sensitivity of the e.ffects of aeroengine thrust variation on basic flight per）brmance were analyzed. The results show that the sensitivity of minimum level Mach number subjected to aeroengine thrust variation is slight, but the sensitivit） of maximum climb rate subjected tO aeroengine thrust variation is signficant. The effect of maximum level Mach number and ceiling depends on aeroengine condition and thrust variation.
