Nacelle Improvements (Formerly Improved Inlet Solution (IIS))
Abstract
Nacelle Improvements (Formerly Improved Inlet Solution IIS): RDT&E funding provides for design, development, and testing of V-22 Nacelle Improvements. This major budget thrust was formerly met by the IIS program. During IIS development, it was realized there are other components in the V-22 nacelle that require readiness improvements and can benefit from the synergy of development simultaneous with IIS; including, but not limited to, the Infrared Suppressor (IRS), Generator Control Unit (GCU), nacelle wiring, heat exchanger, and the nacelle structure. The IIS major budget thrust scope has been expanded to encompass these broader Nacelle Improvements for both the CV-22 and MV-22 fleets. These improvements will increase Engine Time on Wing (ETOW) and overall aircraft readiness/availability, reduce platform operating life cycle costs, and mitigate impacts to aircraft performance. Provides for modifications to the CV-22 nacelle and propulsion system to reduce sand/dust and other particulate matter ingestion, increase engine time on wing and overall aircraft readiness/availability rates, and reduce operations and support costs. This is Air Force Special Operations Command's #1 modification priority for the CV-22 weapon system. Provides for new-construction, zero-time nacelles with structural improvements and vibration reductions. Provides a common configuration Generator Control Unit (GCU) that will be compatible with existing V-22 Variable Frequency Generator (VFG) and Constant Frequency Generator (CFG), support relocation of the GCU, support future generator capacity upgrades and be compatible with advanced prognostic diagnostic technology developed to control all 4 generators more efficiently; increasing V-22 reliability, maintainability and supportability for the fleet. Provides for Analysis of Alternatives, prototyping and demonstration of new Infrared Suppressor (IRS) candidate systems for the V-22. Provides for down-select to a new IRS design, Enginee...
