Innovative Aircraft Design Study (IADS), Task II. Volume I.

The study was concerned with the conceptual design and evaluation of military heavy logistics transport aircraft entering service in the 1990-2000 time period. Design paylaods of 200,000-600,000 lb. and design ranges of 3600-7200 nm were considered. Takeoff field length was 8000 ft. in most cases. Suitability for commercial usage was a major objective. Computer aided design techniques were employed extensively for airplane synthesis and analysis. The study was accomplished in two phases. Phase I included parametric design and analysis of transports in the payload/range categories cited above. An advanced technology review, including evaluations and sensitivity analyses, was accomplished. These studies indicated that substantial gains were possible in reducing operating costs by incorporating both the low risk technology and innovative designs available in 1985, and advanced technology such as composite structures available at a later time. Additional effort is required to identify this increased cost of higher risk advanced technology to determine its cost effectiveness. In Phase II, a baseline mission requiring 3600 nm radius and 400,000 lb. payload was selected.
