A dynamic model of a piston engine mounted in the aeroplane has been formulated. The equations of motion have been identified for 4-cylinder boxer Franklin installed in the Polish acrobatic Koliber plane. Comparision of engine body acceleration RMS values obtained by measurement and simulation has given positive results. The engine body vibrations in the plane of the reactive torque of forces have been investigeted in the Matlab-Simulink environment and with the help of the INSITE software. It has revealed relationships of system responses to its parameters and excitation values to assure a methodical approach to the suspension synthesis. The asymtotic methods have given multidimensional expressions for natural frequencies and resonance curves. The numerical methods have been applied to establish stability boundaries, chaos occurrence, routes to chaos and to identify chaos symptoms.
