Use the MBSE method to design the thrust adjust function of Vehicle

In order to take advantage of the digital transformation to support the aerospace system engineering development, this paper analyzes the whole life cycle development process of the vehicle under the traditional development model, and based on that, introduce a new development model called Electrical System Integration that can concurrent design by integrating information sharing and activity synchronization which is not only inherits the traditional system engineering development experience but also have optimizes the system design. With the help of The Model based Systems Engineering method can make the model and data are applied to the whole life cycle development of products, to realize the model definition system, data-driven process, knowledge and quality assurance. Finally, make an example on the process of design scheme come out and decision-making for the system function of power supply and distribution.
