摘要
前起机轮回中试验是保证飞机起飞离地后有足够的纠偏力矩可使前机轮能够在任何位置回到中立位置,关系到飞机二次着陆的方向稳定性。采用气压传动技术,通过气源带动顶升装置顶起前起落架,在到达指定位置后,通过反向驱动装置,实现与起落架的快速撤离,完成对前起落架机轮回中性能试验的考核验证。
Neutral test is to ensure NLG wheel can go back to the correct position when the airplane take off,that concerns the direct stability of the 2 nd landing. To adapt the pneumatic transmission technology,towing the NLG by jacking equipment with air supply,when the sliding tube reaching the specified position,reverse driving equipment,and quick withdrawing between the towing and NLG. When meeting the requirement,that can exam and verify the NLG wheel neutral performance.Nose Landing gear,jacking,Quick evacuation
