Applying the quality function deployment on the V-22 Osprey

Developing requirements for correction of deficiencies requires detailed analyses of top-level system requirements and subsystem specifications. Application of the quality function deployment provides a rigorous systems engineering process to define the correct requirements accurately. In addition, performing a gap analysis is another important task in order to compare the requirements at the interfaces between systems especially with respect to external environmental factors. On the V-22 Osprey, these tools and processes were applied to optimize cost-wise readiness of the lower nacelle system through a holistic review of inter-related systems in the propulsion function. A dedicated team of systems engineers and subject matter experts from Bell-Boeing, Rolls-Royce, and Naval Air Systems Command (NAVAIR) performed a thorough requirements analysis of the lower nacelle system. This review traced the requirements flow from external environmental factors into the engine inlet, through the engine air particle separator, to the engine, and exhausting through the infrared suppressor.
