Abstract : The Integrated Digital/Electric Aircraft (IDEA) is an aircraft concept which employs the following systems: Advanced Electrical Power Generation and Engine Starting, Power Distribution and Management, Electromechanical Actuation Systems, Electrical Deicing, Electrically Driven Environmental Control System, Advanced Data Distribution, and Digital Flight Control System. After detailed trade analysis of candidate systems, preferred systems were applied to the baseline configuration, which contains advanced technology in all areas except for secondary power and flight control systems. The Baseline is a stretched-fuselage Lockheed L-1011 derivative carrying 350 passengers over a design range of 4600 n.mi. with performance benefits evaluated at the average stage length of 2500 n.mi. It was assumed that the advanced technologies would reach technology readiness' (be at a sufficiently advanced stage of development for commitment to an aircraft design) in 1990 for an aircraft entering service in 1994. An additional configuration, the Alternate IDEA, was also considered. For this concept the design ground rules were relaxed in order to quantify additional synergistic benefits. The major objectives of the study were to define an IDEA configuration, define technical risks associated with the IDEA systems concepts, and to identify the research and development required activities to reduce these risks.
