Example systems, methods, and apparatus are disclosed herein. Disclosed systems include a superconducting (SC) motor to power a propulsor of an aircraft and a liquid hydrogen (LH2) subcooling system including a primary flowline fluidly coupled to a cooling assembly of the SC motor, a secondary flowline fluidly coupled to the primary flowline, an expansion valve coupled to the secondary flowline, and a heat exchanger fluidly coupled to the primary flowline and the secondary flowline. Disclosed systems also include a fuel cell stack coupled to the primary flowline and the cooling assembly.

A power supply system includes: a prediction unit that, based on required power, generated power, and a current SOC of a power storage device, predicts a predicted SOC that is an SOC of the power storage device obtained after a predetermined time; a correction power amount determination unit that determines a correction power amount used for reducing a deviation between the predicted SOC and a target SOC to be achieved; a target generated power correction unit that determines corrected target generated power by correcting target generated power with the correction power amount, the target generated power being the generated power determined in accordance with the required power; and a control unit that can control a power generation device based on the corrected target generated power.

A propulsor fan and drive system having reduced noise emission is disclosed. The propulsor fan includes a blade fan having a plurality of blades. The blade fan is tensioned at the tips of the plurality of blades. By tensioning the tips of the blades, an angle of the blades is maintained during operation of the propulsor fan thereby reducing noise that may result from changes in the angle of the blades.

The present disclosure relates to a flight system and a failure responding method therefor. A flight system includes: a plurality of fuse boxes configured to control application of a voltage to at least one propulsion device; and an interlock control apparatus configured to control interlock lines between fuse boxes connected using the interlock lines among the fuse boxes to synchronize and control opening of the fuse boxes connected using the interlock lines.

An apparatus for facilitating propulsion of a vehicle. The apparatus comprises a housing with an interior space, an inlet, and an outlet, a propulsion mechanism, and a gimbal. The propulsion mechanism is disposed in the interior space and comprises and an upper rotor and a lower rotor rotatably mounted on a first portion and a second portion of a spindle. The upper rotor rotates in a first direction and the lower rotor rotates in a second direction opposite to the first direction. Upper rotor blades have a first blade pitch and lower rotor blades have a second blade pitch opposite to the first blade pitch. The rotating of the upper rotor and the lower rotor creates a fluid flow from the inlet to the outlet for generating a directional thrust. The gimbal rotatably attaches the propulsion mechanism to the housing. The housing is rotatable for vectoring the directional thrust.
