摘　　要：改装翼梢小翼可以有效降低诱导阻力,减少飞机燃油消耗和尾气排放,提高飞机经济性的同时保护环境;然而翼梢小翼通常价格昂贵,在进行翼梢小翼改装项目时,需要对翼梢小翼进行经济性评估。以A型飞机改装翼梢小翼为例,运用成本收益理论,建立A型飞机改装翼梢小翼经济性评估模型,分析平均航段距离、飞机平均日利用率、付款方式、贴现率等因素对翼梢小翼投资回收期的影响规律。结合实例评估分析某航空公司A型飞机改装翼梢小翼的经济性,为航空公司改装翼梢小翼预先的投资回收期计算分析提供参考依据。The winglet can effectively reduce the induced drag,fuel consumption and exhaust emissions,meanwhile,it is eco-friendly and profitable.However,an economic evaluation is necessary before carrying out the winglet modification project,due to its cost.Based on the cost-benefit analysis,an economic evaluation model of Atype aircraft modified the winglet is established.The influences of the average flight distance,daily utilization rate of the aircraft,the payment method and the discount rate on the winglet’s ROI(return on investment)are analyzed.Finally,the case analysis will be given,combined with the evaluation of feasibility and finance,which provides a reference for airlines to modify the winglet.
