Abstract: An aircraft with an integrated boundary layer ingesting propulsion having a mechanically-distributed propulsion system. The mechanically-distributed propulsion system may include an engine to generate a mechanical drive power, a drive shaft, a direction-reversing transmission, and a propulsor fan. The drive shaft may be operatively coupled to the engine to receive the mechanical drive power. The direction-reversing transmission may have a first rotating shaft and a second rotating shaft, the first rotating shaft operatively coupled to the drive shaft to receive the mechanical drive power, which is configured to redirect the mechanical drive power received at the first rotating shaft from a first direction to face a second direction at the second rotating shaft. The propulsor fan may be coupled to the second rotating shaft to convert the mechanical drive power into thrust.

Abstract: A LIDAR system for vehicle operation that can operate in degraded visual environments (DVE) is described. The LIDAR system may use a spatial light modulator to find the phase conjugate of the DVE being traversed by the laser beam and cancel out the backscatter from the DVE, which allows the detection of extremely small numbers of directly reflected photons reflected by a target surface. If the target is not detected, the LIDAR is iteratively scanned to its maximum available depth of focus until the target is acquired. The LIDAR system is especially useful for autonomous landing of VTOL aerial vehicles in locations where the target landing spot is approximately known but cannot be directly visualized due to DVE media, such as smoke, dust, fog, or the like.

Abstract: Fixed-wing short-takeoff-and-landing aircraft and related methods. The aircraft comprise an airframe comprising a rear wing assembly and a forward wing assembly positioned forward of the rear wing assembly, a rear plurality of blowing rotor assemblies operatively coupled to the rear wing assembly that are configured to blow air across the rear wing assembly to induce lift in the rear wing assembly, and a forward plurality of blowing rotor assemblies that are operatively coupled to the forward wing assembly and configured to blow air across the forward wing assembly to induce lift in the forward wing assembly. The methods comprise inducing lift in a forward wing assembly by blowing air across the forward wing assembly with a forward plurality of blowing rotor assemblies and inducing lift in a rear wing assembly by blowing air across a rear wing assembly with a rear plurality of blowing rotor assemblies.

Abstract: A method of operating a facility includes identifying, by a controller, a ground vehicle approaching a restricted access area, and determining, by the controller, if the identified ground vehicle is authorized to enter the restricted access area. The controller permits the identified ground vehicle to enter the restricted access area when the controller determines that the identified ground vehicle is authorized to enter the restricted access area. The controller determines if an object other than the identified ground vehicle is approaching the restricted access area with the identified ground vehicle, and activates protective action when the controller determines that the identified ground vehicle is not authorized to enter the restricted access area or that an object other than the permitted ground vehicle is approaching to enter the restricted access area with the permitted ground vehicle.
