Abstract:At present the installation of aeroengine overall unit to the aircraft body is mostly realized by manual work with man-powered vehicle. To solve its defects of poor efficiency, high labor intensity, easy scratch of aeroengine and so on, a kind of precise numerical-controlled (NC) installation method has been studied. An aeroengine NC installation vehicle based on visual monitoring was developed. And the freedom of the multi-axis attitude adjusting platform in the vehicle was analyzed. Experimental researches have been accomplished for the installation of aeroengine. Experimental results showed that the method and the equipment for aeroengine NC installation had the superiority of convenient operation and high visual degree. The efficiency of the installation for aeroengine was increased by more than one time with the location preci-sion being limited in 0.2mm and the attitude precision being limited in 20'. Meanwhile, the scratch between the aeroengine edge and the engine cabin is avoided in the installation process.
