Progress Toward a New Conceptual Assessment Tool for Aircraft Cost

Abstract

Progress is updated in an ongoing research effort to develop new analytical capabilities for the conceptual assessment of rotorcraft life-cycle cost. Recent developments in both modeling and implementation are reviewed. New parametric equations are presented for cost elements related to development and operational phases, and a software tool for graphical illustration of cost estimates is demonstrated on selected aircraft. The demonstration utilizes case study aircraft concepts which emphasize the model’s new features for consideration of electric battery-powered aircraft and assessment cases in government acquisition where validation of estimates against legacy fleet aircraft is required. Near-term plans for additions and updates to the cost model are offered in conclusion.
