Design and Verification Method for Flammable Fluid Drainage of Civil Aircraft Based on DMU

Abstract

Due to the complex internal environment, numerous system equipment and pipe lines, the civil aircraft has many fire safety feature elements, and the configuration of these feature elements needs to be managed and controlled during the design iteration process. However, the traditional methods and means has not met the needs of aircraft development. This paper proposes the use of digital methods and means to construct a “DMU based on flammable fluid drainage”, analyzes and summarizes the key technologies of DMU modeling and simulation, At the same time, according to the method of system engineering, the design and verification method of flammable fluid drainage based on DMU are studied.
