This paper aims to present the assumptions, analysis and sample results of numerical modeling and analysis of dynamic events encountered in emergency cases during deployment of parachute rescue system (PRS) and hard landing of a small gyrocopter. The optimal design requires knowledge of structural loads and structural response – the information obtained often from experiment. Numerical simulation is presented as an alternative tool for estimating these data.
Structural analyses were performed using MSC.Nastran. Multibody simulations were done using MADYMO system.
Initial design parameters were evaluated and verified in numerical simulations. Some of the resulting conclusions were proven during the test flights.
Some chosen results of simulation of dynamic problems are presented. They can be useful as reference values for similar cases for light aircraft analysis.
The paper presents an alternative way of assessing structural response parameters in the case of emergency dynamic events of usage of PRS. The results can be used in other projects.
