为了满足飞行器在任务过程中气动外形最优化目的,需要以变体技术对机翼的外外形与姿态进行适当的调整。为此建立了一个测试系统模型,并以此来用来研究与探索多自由度变体机翼技术。该系统以一个优化的三杆并联机构为基础,以LabVIEW虚拟仪器系统建立人机界面和控制系统,实现可控的三自由度运动。对系统的运动测试表明,该实物变体机翼模型能按照要求实现前后掠、变翼展、变上下反角三种变形,驱动误差最大为3.61%。 In order to meet the aerodynamic shape optimization needs of the aircraft during the mission, the outer profile and posture of the wing need to be adjusted appropriately by the variant technology. To this end, a test system model was established and used to study and explore the multi-degree-of-freedom variant wing technology. Based on an optimized three-bar parallel mechanism, the system builds man-machine interface and control system with LabVIEW virtual instrument system to achieve controlled three-degree-of-freedom movement. The test of the system shows that the physical variant wing model can achieve three kinds of deformations: forward and backward sweep, variable wing span and upper and lower reverse angles, the maximum error is 3.61%.
