Systems Engineering Application for Rotorcraft Systems

This paper discusses a modern systems engineering and Product Lifecycle Management (PLM) approach to aerospace system design. The methodology is focused on improved redesign capability and design integration and is implemented on a rotorcraft drive system. The rotorcraft drive system is a complex system that is tightly coupled with propulsion and rotor design, and airframe geometry. The preliminary design of this system takes into consideration the vehicle concept, power requirements, airframe layout for engine and transmission housing, and gear optimization. The digitization and automation of system design method that include product and process trades is discussed in this paper.
