Patent number: 11897600Abstract: An aircraft wing is disclosed herein having a fixed-location trip device placed along the span of the wing to transition airflow from laminar flow to turbulent flow so that potential load increases are limited and flight performance uncertainties associated with laminar flow wings are reduced. Wings designed for extended laminar flow offer the potential to significantly reduce airplane drag and fuel consumption. A collateral impact of a laminar flow wing is the generation of elevated wing loads at critical load conditions. This impact is mitigated by controlling the downstream limit of transition at these critical load conditions.Type: GrantFiled: June 28, 2019Date of Patent: February 13, 2024Assignee: THE BOEING COMPANYInventors: Jeffrey D.

Patent number: 11884175Abstract: Battery powered quadrotors or drones have a limited operation time. To extend operation time, a powered tether can be used. This tether provides power to the drone allowing it to stay up indefinitely. Most tethered drones are captured to the base station. The tether can reel in and out as the drone moves, but the drone can't go higher or further than the maximum length of the tether. If the tether can be automatically disconnected, the drone could fly off for some remote mission, assuming the drone had an onboard power source such as rechargeable batteries. The present invention relates to a self-powered drone tether that comprises a rechargeable drone in flight which is referred to as the rechargeable drone, a drone that carries a powered tether which is referred to as the tether drone, a coupling mechanism between the rechargeable drone and the tether drone, and a base station with a powered tether and tether deployment system.Type: GrantFiled: June 26, 2019Date of Patent: January 30, 2024Assignee: Robotic Research OpCo, LLCInventors: Alberto Daniel Lacaze, Karl Nicholas Murphy, William Becker, Steven Rotundo

Patent number: 11845571Abstract: A solar array structure for a spacecraft is based on a modular approach, allowing for arrays to be designed, and designed to be modified, and manufactured in reduced time and with reduced cost. The embodiments for the solar array are formed of multiple copies of a “bay” of a multiple strings of solar array cells mounted on semi-rigid face-sheet structural elements. The bays are then placed into frame structures made of tubes connected by nodes to provide an easily scalable, configurable, and producible solar array wing structure. This allows for rapid turnaround of program specific designs and proposal iterations that is quickly adaptable to new/future PhotoVoltaic (PV) technologies and that can create uniquely shaped (i.e., not rectangular) arrays, allowing for mass production with simple mass producible building blocks.Type: GrantFiled: September 19, 2022Date of Patent: December 19, 2023Assignee: Maxar Space LLCInventors: Harry A.
