    Abstract: A noise reduction system in a vertical takeoff and landing (VTOL) vehicle is provided. The noise reduction system is configured to: identify a noise level at which the VTOL vehicle can operate; dynamically determine a motor-specific fan RPM and a motor-specific fan pitch that will allow the vehicle to not exceed the noise level based on vehicle noise characteristics and an ambient noise level; determine whether the determined motor-specific fan RPM and motor-specific fan pitch will allow the vehicle to operate within its safety envelope; and cause a motor-specific fan RPM command and a motor-specific fan pitch command to be sent to the lifter motor controller to cause the vehicle lifter motors to operate at the determined motor-specific fan RPM and motor-specific fan pitch when it is determined that the determined motor-specific fan RPM and motor-specific fan pitch will allow the VTOL vehicle to operate within its safety envelope.

    Abstract: A computer-implemented method of navigating a vertical take-off and landing (“VTOL”) vehicle near a landing zone, may comprise receiving data related to a first radar signal reflected from at least one corner reflector; determining whether the received data is consistent with a predefined target landing zone; upon determining that the received data is consistent with the predefined target landing zone, determining a location of the VTOL vehicle relative to the predefined target landing zone, using a second radar signal reflected from at least one corner reflector; and determining whether the location of the VTOL vehicle is consistent with a predefined landing position.

    Abstract: Disclosed are methods, systems, and non-transitory computer-readable medium for landing a vehicle. For instance, the method may include: before a descent transition point, receiving from a service a landing zone confirmation including landing zone location information and an indication that a landing zone is clear; determining a landing flight path based on the landing zone location information; and upon the vehicle starting a descent to the landing zone using the landing flight path: receiving landing zone data from at least one of a radar system, a camera system, an altitude and heading reference system (AHRS), and a GPS system; performing an analysis based on the landing zone data to determine whether an unsafe condition exists; and based on the analysis, computing flight controls for the vehicle to continue the descent or modify the descent.

    Abstract: A computer-implemented blockchain system for distributing, updating and verifying the installation of software embedded in an aircraft and for creating a built-in blockchain record of distributing, updating and verifying activities as proofs, including: a first node to insert into the distributed ledger in a first block of the blockchain storing a service record that contains distributable software code for updating the software embedded in the aircraft, and that specifies rules prescribing activities for loading, installing and verifying the software; a second node programmed to access the distributed ledger to obtain the service record and to initiate loading and installing activity performed upon the software embedded in the aircraft and to insert into the distributed ledger a second block of the blockchain storing a service record of at least one loading, installing and verifying activity was performed; and a third node to access the distributed ledger to obtain the service record.
