Abstract

The invention discloses a ground test verification system for dragging and removing control of a flexible assembly based on a tether connection, which includes an active aircraft simulator, a target aircraft simulator, a marble air flotation platform, a ground test comprehensive monitoring system and a tether. The invention can simulate the dragging dynamic characteristics of the rope assembly under the condition of zero gravity in the ground environment, and test and verify the dragging control scheme and technology of the rope assembly.

Description

technical field [0001] The invention relates to the field of aircraft ground test verification, in particular to a tether-connected flexible assembly drag removal control ground test verification system. Background technique [0002] As a complex flexible multi-body system, the tether assembly has complex dynamic laws, significant nonlinearity, and many uncertainties. The use of conventional mathematical simulation methods cannot effectively verify the dragging motion and control laws. Therefore, it is necessary to carry out the ground test of the towed removal of the tethered assembly to grasp the law of the towed dynamics and control of the tethered assembly, to verify the control strategy and technology for the towed removal of non-cooperative targets; to improve the understanding of the tethered dynamics and control Understanding and revising the control scheme and the index requirements for measuring equipment and tether retractable devices provide important support for...
