Monte Carlo Simulation for Inertia Moment Measurement Test of Seaplane Model

In order to evaluate the reliability of the test data and improve the test quality, this paper analyzes the uncertainty of the inertia moment measurement test of the seaplane model based on the Monte Carlo method. The results show that the standard uncertainties of the moment of inertia Ixx, Iyy and Izz respectively are $0.25\mathrm{k}\mathrm{g}\mathrm{m}^{2}, 0.26\mathrm{k}\mathrm{g}\mathrm{m}^{2}$ and 0.02 kgm2. The distribution of the simulation results of the moment of inertia Ixx, Iyy, Izz and the product of inertia Ixy, Iyz, Izx conforms to the normal distribution. Monte Carlo simulation is effective for evaluating the measurement of inertia moment of seaplane model, and it can significantly improve the test quality.
