Accuracy Analysis of Hybrid Mechanism for Aero-Engine Installation

The accuracy of engine installation directly affects the aircraft performance and flight safety. At present, the installation of domestic aircraft engines mainly relies on manual work, which has problems such as low operational accuracy and efficiency. This study proposes a hybrid mechanism to adjust spatial 6-DOF configuration of engine. On this basis, the forward kinematics and accuracy model of the mechanism are established, and the operation accuracy of the mechanism is analyzed. This study provides a theoretical model and experiment data to ensure the accuracy for the engine installation. This study has important value to improve the stability of aircraft engine installation quality.
