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 precision
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.
