A fixed-wing, powered, non-buoyant, enclosed cargo aircraft design for carrying low-density wind turbine components is disclosed. The cargo aircraft can include a fuselage defining a forward end, an aft end, and a continuous interior cargo bay that spans almost all of a length of the fuselage from the forward end to the aft end, the cargo bay being capable of enclosing a maximum payload length approximately in the range of about 75 meters and about 125 meters. The aircraft is capable of short takeoff and landing (STOL) operations while carrying a maximum payload weight. The takeoff field length can be less than about 10 lengths of the maximum pay load length.

Low-density fixed-wing cargo aircraft designs for enclosed non-buoyant transportation of wind turbine components

Systems, methods, and aircraft for managing center of gravity (CG) while transporting large cargo are described. Management of CG is achieved in many ways. In some instances, the aircraft itself is designed to assist in managing CG by providing fuel tanks that minimize the impact of fuel on the net CG of the aircraft. The fuel tanks utilize only a small amount of available volume in the wings for fuel. Disclosures related to properly managing CG while loading wind turbines onto cargo aircraft are also provided. The CG management techniques provided for herein allow for the transportation of wind turbine blades via aircraft, running counter to the typical rail or truck transportation of the same. One such management technique includes accounting for how a rotation of the blades when loading impacts the CG of the blades, and thus taking this into account when placing the blades in the aircraft.

Methods for managing center of gravity while loading wind turbine blades on a cargo aircraft using internally-extending rails

A cargo aircraft configured to carry a portion of its payload in a cargo bay volume enclosed by a moveable nose door and supported by a structural extension of the fuselage that extends forward into the moveable nose door is disclosed. Examples include an aircraft with a continuous cargo bay extending from an aft end of a fixed portion into forward portion inside a nose door, where the portion of the cargo bay in the nose door is supported by a cantilevered support structure extending forward a length from a cargo opening into the fixed portion and such that the support structure extends into the nose door when the door is closed. The length of the support structure defines a supported cargo volume of at least about 15% of the overall volume of the fuselage forward of an aft end of the support structure.

Volumetrically efficient cargo aircraft

A fixed-wing cargo aircraft having a kinked fuselage to extend the useable length of a continuous interior cargo bay while still meeting a tailstrike requirement is disclosed. The fuselage defines a continuous interior cargo bay along a majority of its length and a pitch axis about which the cargo aircraft rotates during takeoff while still on the ground. The fuselage includes a forward portion defining longitudinal-lateral plane of the cargo aircraft an aft portion extending aft from the pitch axis to the aft end and containing an aft region of the continuous interior cargo bay that extends along a majority of a length of the aft portion. The aft portion has a centerline extending above the forward upper surface of the aircraft.

Aircraft fuselage configurations for avoiding tail strike while allowing long payloads

A fixed-wing cargo aircraft having a kinked fuselage is disclosed. The fuselage contains a continuous interior cargo bay, and includes a forward portion, an aft portion, and a kinked portion forming a junction in the fuselage between the forward and aft portions. The kinked portion contains a transition region of the cargo bay and defines a bend between a forward centerline and an aft centerline. The kinked portion is formed with a forward transverse frame section, a separate aft transverse frame section, and a plurality of longitudinal frame elements extending between the forward and aft frame sections, the forward frame being coupled to an aft end of the forward portion and the aft frame section being coupled to a forward end of the aft portion such that the aft frame section is angled with respect to the forward frame section about a lateral axis of the cargo aircraft.

Methods and systems for efficiently loading cargo transports, such as cargo aircraft, are described. The methods and systems rely upon payload profiles for various payloads where the payloads include repeatable payloads that have the same characteristics. Based on the payload profile, the payload is positioned at a designated location in an interior cargo bay of the cargo transport. The designated location is denoted by one or more pre-formed markings in the interior cargo bay that establish where a payload having the respective payload profile should be positioned in the bay. The payload can then be secured in the bay. Because the designated location accounts for centers of gravity, the payload can be loaded and secured in the bay without having to run various calculations each time a payload is loaded. Systems and methods related to how the payloads are packaged in an efficient, expeditious manner are also provided.
