| Abstract: |
| Objective To study influences of flexible fuselage on landing gear when a blimp airship lands. Methods An equivalent model of blimp airship with landing gear and flexible fuselage was established. An airship model with flexible fuselage using virtual prototype was applied in LMS simulation platform. Dynamic responses in landing of landing gear were simulated when the flexible fuselage was considered. Results Flexible fuselage was able to contribute to absorbing energy of shock absorber, alleviating overload and reducing rebound times during landing appropriately. Conclusion Flexible fuselage can decrease the burdens on landing gear, extend the life of landing gear, and improve the safety of the airship. |
