DOM Aerospace is proud to present Hyperion, an Ultra-Large Heavy Lift Aircraft (UHLA) designed in response to the 2002-2003 American Institute of Aeronautics and Astronautics (AIAA) Undergraduate Team Aircraft Design Competition. Hyperion incorporates a biplane wing that is optimized to carry a payload of 1.2 million pounds, with provisions to carry ten M1A2 Abrams tanks weighing 1.39 million pounds. Hyperion is designed with weight and cost in mind to operate alongside and replace the C-5 Galaxy in the future.

The benefits of a biplane include a decrease in induced drag, reduced fuel burn, and the ability to decrease wingspan, allowing Hyperion to operate from existing airport infrastructure. Hyperion is designed with the goal of minimizing both empty and takeoff gross weight (TOGW). Structural and volume optimizations yielded direct decreases in TOGW, along with aerodynamic and performance optimizations that were incorporated to achieve the lowest fuel burn possible.

The most important component of any cargo aircraft is the cargo bay. Hyperion?s cargo bay has the structural capability to carry ten M1A2 Abrams tanks, and the comfort to economically and competitively carry over 1,080 commercial passengers on the cargo deck, with an additional 210 on an upper deck. 1,290 paratroopers can be carried and deployed from both decks of the aircraft. Hyperion is also capable of lifting 72 loaded 463L pallets, 304 Medical Litters with 504 support personnel, 45 HMMWV, six Apache helicopters, and even two inert or one fueled Shuttle Solid Rocket Booster (SRBs). With a design payload range of 5,000 nautical miles and the capability to refuel in flight, Hyperion has the capability to deploy entire battle groups anywhere in the world within a matter of days rather than weeks.

The efforts of DOM Aerospace have resulted in an aircraft that has the lowest obtainable empty weight, and the lowest fuel burn for the AIAA RFP?s main mission. Hyperion is designed as a cargo aircraft to carry a 1.2 million pound payload 5,000 nautical miles, with the versatility and provisions to carry a variety of payloads, heavier or lighter, at the sacrifice or addition of fuel and range. Hyperion is DOM Aerospace?s practical and cost effective cargo aircraft that represents the best solution to the RFP.
