For the c-130 of the future?

"The conceptual design is for a large tandem wing aircraft with V-22 type engines and 50-foot rotors at each of the four wing tips. The C-130-size fuselage would have a 747-inch-long cargo bay with a rear loading ramp that could carry 110 paratroopers or 150 standard-seating passengers. In cargo configuration, it would accommodate eight 463L pallets.[7]

In addition to the baseline configuration, the Bell-Boeing team is including eight possible variants, or "excursion designs", including a sea-based variant. The design team is planning on payloads ranging from 16 to 26 tons and a range of 420 to 1000 nmi. The baseline version includes a fully retractable refueling probe and an interconnecting drive system for power redundancy.[7]

One of the design excursions explored by the team, dubbed the "Big Boy", would have 55-foot rotors and an 815-inch-long cargo bay, making it able to carry one additional 463L pallet, and accommodate a Stryker armored combat vehicle."

"Besides the research performed jointly under the contract, Bell has funded additional research and wind tunnel testing in cooperation with NASA and the Army.[9] After submission of initial concept study reports, testing of full-scale components and possibly a sub-scale vehicle test program was expected to begin.[1] Pending approval, first flight of a full-scale prototype aircraft was slated for 2012.[7]"
