Abstract: A three-dimensional orthogonal woven composite outlet guide vane and a manufacturing method are provided. Near-net-shaped manufacturing of the outlet guide vane is realized, and a vane profile-platform junction of the outlet guide vane is reinforced by designing a bifurcation of the preform. A basic structure of a three-dimensional orthogonal woven composite and a bifurcation of the vane profile-platform junction are used, so that the ultimate strength under tension, compression and bending of the outlet guide vane structure are significantly improved, and the weight of the outlet guide vane is reduced. Structural load bearing and force transmission functions of a strut are provided by the outlet guide vane while the functions of vane rectification, noise reduction and others are ensured. As a result, the weight and dimensions of an aeroengine, as well as structural complexity, are reduced by removing struts.

Abstract: The present disclosure relates to a smart battery. The smart battery includes a battery shell, layered cells, a positive electrode, a negative electrode, an embedded multi-source sensor group and an intelligent chip. The smart battery can detect the temperature and the pressure of the core of the battery and the current of the battery in real time by using the intelligent chip and the embedded multi-source sensor group, thereby realizing a real-time monitoring of the working state and safety state of the battery, and improving a safety and the reliability of the battery on the basis of realizing the self-sensing function of the battery. The modification to the conventional battery structure by adding the intelligent chip and the embedded multi-source sensor group makes up the gap in research and development, manufacturing and production of the smart battery on the premise of ensuring that the battery volume remains unchanged.
