飞艇载荷能力影响因素分析

Analysis on Affecting Factors for Load Capacity of Airship

飞艇载荷能力会随着大气环境因素和飞艇自身飞行状况的变化而变化,为了找出这种变化规律,对飞艇载荷能力的影响因素进行研究。首先分析飞艇在飞行过程中处于平衡状态下的受力情况,得出对飞艇载荷能力的各种影响因素,而后通过进一步的理论分析,在一定的假设前提下,建立飞艇受力的数学模型,并利用Matlab软件进行仿真分析,给出飞艇载荷能力与大气环境、飞行情况、初始充入氦气情况、起飞高度之间的数值变化关系。该研究可为飞艇的使用提供借鉴和理论依据。

In order to find rules that load capacity of airship varies with atmosphere environment and flight status of airship, research affecting factors for load capacity of airship. First the endured forces of conventional airship under equilibrium condition were analyzed. And affecting factors for load capacity of airship were gained. Through further theoretical analysis, force mathematical model of airship was established basing on certain assumptions and simulations were carried out with Matlab software platform. Relationship of value changes between load capacity of airship and atmosphere environment, flight conditions, the initial conditions of charging into helium, taking off height were given, which making itself a theoretical basis for the use of airship.
