| description | The FAA-P-8110-2 Airship Design Criteria defines the airworthiness standard requirement. In order to make the design of landing gear to fulfill the requirements perfectly, a methodology of load calculation for landing gear is presented in this paper, which is based on double-springs’ vibration model. According to classical theories of dynamics, the differential equations of the system are derived herein. A simulation tool for this model is developed based on Python scientific modules, which is built in visualization and friendly operation. Taking a certain manned airship model as the research object, the main factors affecting the load of the landing gear are analyzed, and the reasonable values of the load are calculated by simulation. The results show that the proposed method can satisfy the airworthiness standard requirement of landing gear for landing gear load calculation. Under the given conditions of gasbag differential pressure, the landing gear load is decreased with the increase of gasbag pressure. |
