Abstract: Mass property parameters are important basic parameters of aircraft. In order to accurately measure the mass property parameters of large scale aircraft model, this paper presents a measuring method which combines the four-point approach and the dynamic approach to measure mass, centroid, centroidal deviation and moments of inertia. The principle of measurement is described and the measurement errors are analyzed. The integrated mass property parameters measuring device is developed for large scale aircraft model and the all the parameters can be measured in one installation. Experimental results show this method has a high precision and other advantages such as less clamping process, convenient operation, high efficiency and good stability.
