Abstract

Embodiments of the present invention provide for the detection/identification of objects near a rotary-wing/VTOL aircraft such as a helicopter, drone, or an eVTOL (electric Vertical Take Off & Landing) aircraft using LiDAR. Various aspects of the present invention may include installation of one or more LiDAR devices on a mast of a rotor system of a rotary-wing/VTOL aircraft. The LiDAR device(s) may be pointing outward from the central axis of the mast and may be aligned to avoid interference form the rotor blades. Multiple LiDAR devices may be oriented/pointed above, below or in-plane with the rotor system. As the mast rotates, the LiDAR is pulsed providing a range to objects near the rotor system as the LiDAR emitted beams are scanned through the 360 degree rotation of the rotor mast. A processor determines whether objects detected within the detection envelope/volume represent a threat or hazard condition to the aircraft.

Abstract

An electronically reconfigurable battery includes a number of battery modules selectively interconnected by a number of electronic switches, wherein a selectable number of battery modules may be connected either in a series configuration or in a parallel configuration, as a result of placing selected switches of said plurality of switches in open states or closed states. In a parallel configuration, the battery provides power to a primary load, such as a propulsion load for a vehicle. In a series configuration, the battery is configured to provide a high voltage and high power output to a short-term and/or pulsed load, such as an additional load provided on the vehicle. Current from the battery is limited in one of three ways: a) by the batteries themselves; b) a current limiting device or system in series with the total erected battery; or c) a single level power converter or current limiter that is used to erect and charge the capacitor bank in a sequential one level at a time manner until the battery is fully erected and the capacitor is fully charged.

Abstract

A lifting apparatus for devices used for detection, observation, air intake or communication on a submarine comprises a first movable mounting unit and a second movable mounting unit equipped at the top of them with at least one detection or communication device and at least one actuator associated with the first movable mounting unit and/or with the second movable mounting unit to move them along a main direction of movement. The apparatus further comprises a supporting member extending along the main direction and interposed between the first movable mounting unit and the second movable mounting unit and also having a pair of guides, each extending along the main direction and slidably coupled to a respective movable mounting unit to guide its movement along the selfsame main direction.

Abstract

A drive unit (40) for an aircraft ground wheel (Ί 2) associated with a brake unit (30) for braking the ground wheel (12) is disclosed, the drive unit (40) comprising a driving motor (42) being drivingly coupleable to the ground wheel (12); and a cooling system including at least a drive cooling unit (52) being configured to generate a drive cooling air stream (54) for cooling the drive unit (40) and a brake cooling unit (62, 70; 72, 74) configured to generate a brake cooling air stream (64) by sucking in air from the brake unit (30). Further disclosed is a method of controlling such drive unit (40) in which the cooling system is driven by the driving motor (42) of the drive unit (40), the method comprising decoupling the driving motor (42) from the ground wheel (12) and increasing the rotational speed of the driving motor (42) to increase the amount of generated drive cooling air (54), when an operating condition of the ground wheel (12) and/or of the drive unit (40) is switched from a propulsion mode to a non-propulsion mode.
