The Mono Tiltrotor design is 1/3rd of the structural weight, burns 1/3 the amount of fuel, is 1/2 of the size as measured by rotor diameter, and nearly twice the speed of legacy helicopter concepts for long range (750 to 1000 nautical mile) cargo missions. This performance advantage is due to...
...its system level architecture and does not rely on subsystem technology advances. The architectural features that deliver this breakthrough performance are the large rotor disk with minimal download in hover, and the cruise optimized wing combined with a small frontal area.The modularity of the aircraft architecture and mission packages confers several advantages. The aircraft can be disassembled for stowage and transport, and then reassembled at point of use. Maintenance and repair are simplified by having highly accessible components and sub-assemblies, with most major components only one or two layers deep into the aircraft. Unlike legacy aircraft that are designed around a mission package, the Mono Tiltrotor carries all mission packages external to the airframe using a bearing at the aircraft's center of gravity. The advantage of externalizing mission packages in this way is that their size and volume are less constrained, weight and balance are simplified, and specialized mission packages such as for CASEVAC or surveillance can be separately managed as independent development programs. This external bearing interconnection enables rapid mission package customization for cargo (using a suspended cargo pod), attack (using sponsons and armaments), or other missions at the place and time of need.
In summary, the Mono Tiltrotor design has breakthrough performance and a modular configuration that will provide operational advantages when fielded, and its capabilities can grow by developing a family of mission packages.
