摘要
俯仰附加转动惯量是平流层飞艇设计的关键参数之一,直接关系到飞艇的姿态和平飞控制。通过工程估算和实验辨识的方法对该参数进行了分析。结果表明,两种方法得到的结果符合较好,可以满足工程设计的要求。分析结果证明了工程估算方法的合理性和实验辨识思路在飞艇飞行品质上应用的可行性。
Pitching added mass inertia is a key parameter in the design of stratosphere airship,which is directly related to airship attitude and hovering control.Both engineering estimation and experimental identification are conducted for this parameter,and the results show that the consistency between the two methods can meet the demand of engineering design.The rationality of engineering estimation and the feasibility of experimental identification in airship flight quality research are verified.
