随着我国改革开放和经济发展,国内轻型飞机研制和生产发展很快,特别是两座以下的超轻型飞机。这两年,北航研制的“蜜蜂”系列飞机,南航研制的AD系列飞机和中航总研制的“小鹰”100飞机等相继通过了中国民用航空总局的型号合格审定,取得了型号设计批准书。 但是,这些飞机在型号审定中都有一个共同的问题,就是发动机和螺旋桨没有适航当局颁发的型号合格证或批准书。当然这个问题在国外同类飞机的型号审查中也是存在的,不过在保证飞行安全的情况下,各个国家采用不同的标准和途径予以解决。超轻型飞机一般采用功率不大于 With China’s reform and opening up and economic development, the development and production of domestic light aircraft has developed rapidly, especially in the two sub-light planes. In the past two years, the “Bees” series aircraft developed by Beihang and the AD series aircraft developed by China Southern Airlines and the “Kitty Hawk” 100 aircraft developed by China Aviation successively passed the type certification of China Civil Aviation Administration and obtained the model design approval. However, there is a common problem with these types of aircraft in the validation of models and there is no type certificate or approval issued by airworthiness authorities for engines and propellers. Of course, this issue also exists in the type review of similar foreign aircraft. However, various countries adopt different standards and approaches to solve this problem under the condition of ensuring flight safety. Ultra-light aircraft generally use less than power
