Patent number: 12145745Abstract: 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.Type: GrantFiled: July 11, 2022Date of Patent: November 19, 2024Assignee: ZSM Holdings, LLCInventors: Etan D. Karni, Scott David Rewerts, Mark Emil Lundstrom

Publication number: 20240343384Abstract: A landing gear system for an aircraft includes a drag brace, a lateral brace, and a support assembly, the support assembly coupled to: a lateral side of the fuselage via the lateral brace, an upper portion of the fuselage via a hinge, and a forward portion of the fuselage via the drag brace. The support assembly can rotate about the hinge connection about a forward-aft axis, with the lateral brace resisting rotation of the support assembly about the forward-aft axis, and the drag brace resisting rotation of the support assembly about a vertical axis. The system includes inboard and outboard landing gear separately coupled to the support assembly to support weight of the aircraft. The hinge transfers vertical forces to the fuselage, moments about the hinge are reacted by forces on the lateral brace, and drag forces are transferred to the fuselage by the drag brace.Type: ApplicationFiled: August 3, 2022Publication date: October 17, 2024Inventors: Jason C.

Publication number: 20240124156Abstract: A fixture for supporting a payload including first and second carriages, first and second cantilevered supports, and a support beam is disclosed. The first and second carriages each have a longitudinal axis that is parallel with the other. Each cantilevered support is coupled to a respective carriage and extends at an oblique angle with respect to the longitudinal axis of the carriage. The first and second cantilevered supports extend substantially parallel to each other. The support beam extends between the cantilevered supports such that a first end of the support beam is coupled to the first support structure and a second end of the support beam is coupled to the second support structure. The cantilevered supports enable the payload to extend into otherwise unusable cargo bay storage space within the nose or tailcones of an aircraft.Type: ApplicationFiled: March 10, 2022Publication date: April 18, 2024Inventor: Etan D.

Patent number: 11873115Abstract: Methods of determining a final space reservation for a new aircraft are disclosed. The methods include using parametric definitions of potential payloads to generate a population of representative payloads for use in creating an initial space reservation. The methods include accounting for and applying a variety of margins on each potential payload and taking the union of potential payloads. Alternatively, the union can be taken first and then the margins applied. A homogenous space reservation can be determined based upon a variety of differently shaped or sized payloads, including a margin build-up to mitigate risk of unknowns associated with future changes in specific payload shapes and sizes, build tolerances, environmental conditions, and/or loading and unloading motions and clearances. Once this space reservation is known, it is possible to design an external shape of a carrying vehicle by staying outside of this space reservation.Type: GrantFiled: July 11, 2022Date of Patent: January 16, 2024Assignee: ZSM Holdings LLCInventors: Scott David Rewerts, Etan D.

Publication number: 20230409049Abstract: During landing and rejected-takeoff flight phases, aircraft drag is a useful force to supplement braking and reduce stopping distance. During descents, aircraft drag is a useful force in steepening flight path angle and achieving higher rates of vertical descent speed at a trimmed forward flight speed in unaccelerated flight. A flight control system is detailed herein that deflects opposing flight control components in a symmetric fashion to increase aircraft drag, while maintaining controllability.Type: ApplicationFiled: November 16, 2021Publication date: December 21, 2023Inventors: Mathew James ISLER, Etan D.

Patent number: 11780583Abstract: 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.Type: GrantFiled: June 27, 2022Date of Patent: October 10, 2023Assignee: ZSM Holdings LLCInventors: Etan D.
