飞机服役年限的确定

Study of Ensuring Aircraft's Service Year

从我军一批退出现役飞机服役年限的统计资料入手 ,并借鉴外军几型飞机的使用情况 ,提出应均衡配置飞机自然寿命、技术寿命和经济寿命 ,合理确定飞机服役年限。并对经济寿命的延长 ,从数学上作了分析。指出 :在机载设备更新换代速度远比飞机平台快的形势下 。

The paper begins with the statistical data of service year of the aircraft withdrawn from our wilitary service. Using for reference the working condition of several types of foreign fight aircraft, the aircraft's natural life, technical life and economical life are put forward, so the aircraft's service year can be determined reasonably. And the prolongation of the economical life is also analysed mathematiclly. It is pointed out that under the circumstances of the renewal speed of the airbone equipment being more faster than that of the aircraft platform, the prolongation of the aircraft's service life may be an appropriate way to achieve 'less investment, higher efficiency' in the equipment developing
