* †Landing gear integration is one of the more fundamental aspects of aircraft design. The design and integration process encompasses numerous engineering disciplines, e.g., structures, weights, runway design, and economics. Although the design process is well-documented, it appears not to have been automated for uses in multidisciplinary design optimization (MDO) procedures. The process remains a key responsibility of the configuration designer. This paper describes the development of an MDO-capable design methodology focused on providing the conceptual designer with tools to help automate the disciplinary analyses, e.g., geometry, kinematics, flotation, and weight. The procedures are described and illustrated by application to a notional large subsonic transport aircraft, illustrating the methods and design issues.

“…[6][7][8] It is an aircraft design synthesis code that breaks historical data and engineering methods down to fine detail and captures the multi-disciplinary interactions of these analyses through a time step integration over a mission. FLOPS has the ability to optimize an Objective function subject to equality and inequality constraints through a list of design variables under the designer's control.…”

There is a general consensus building that historically high fuel prices and greater public awareness of the emissions that result from burning fuel are going to be long-term concerns for those who design, build, and operate airliners. The possibility of saving both fuel and reducing emissions has rekindled interest in breaking very long-range airline flights into multiple stages or even adopting in-flight refueling. It is likely that staging will result in lower fuel burn, and recent published reports have suggested that the savings are substantial, particularly if the airliner is designed from the outset for this kind of operation. Given that staging runs against the design and operation historical trend, this result begs for further attention. This paper will examine the staging question, examining both analytic and numeric performance estimation methodologies to quantify the likely amount of fuel savings that can be expected and the resulting design impacts on the airliner.
