Hierarchy and Interfaces of a MALE UAV Subsystems Using Axiomatic Design and N2 Diagram

Aly M El-Zahaby, Hossam Mahmoud Mostafa and Mohamed Khalil Kamel

Axiomatic design is used as a design methodology for large or complex system design. The first theorem for axiomatic system design describes conditions for equivalence of FRs. The second theorem describes a method of using only leaf levels to represent the hierarchy of the system. A case study of the design of a MALE UAV system is presented. The MALE UAV system architecture is decomposed from top level requirements using the principles of axiomatic design. Also, this work focuses on system interface using N2 diagram which has been first introduced by NASA and also defines the inputs and outputs of each subsystem.
