An electric power system of a flying object may supply power to electric loads including a VTOL motor and a cruise motor. A control device includes an acquisition unit, a determination unit that determines whether a power surplus situation in which surplus power obtained by deducting the required power from the sum of the generated power and the regenerated power is larger than the maximum allowable power is brought about, and a control unit that can execute power consumption increase control for increasing power consumption by reducing the operation efficiency of the cruise motor in the power surplus situation.

Control device for power consumption management of electric VTOL motor

A controller (a control unit) of a power supply system of a vertical take-off and landing aircraft is configured to: after lift is generated by wings (a front wing and a rear wing), perform stop control of controlling electric power supplied to a motor so that rotation of a VTOL rotor continues to stop; temporarily cancel the stop control in response to the temperature of any one switching element detected by a temperature detection unit (a temperature sensor) becoming equal to or higher than a temperature threshold during the stop control; and resume the stop control after the stop control has been temporarily canceled.

Power supply system of vertical take-off and landing aircraft

A controller of a thrust generating device executes one of first control of controlling thrust by changing the pitch angle of each blade while maintaining the rotational speed of a propeller at a reference value, or second control of allowing the thrust greater than the thrust generated in the first control to be generated by making the rotational speed of the propeller larger than the reference value.

Thrust generating device

In a vertical take-off and landing aircraft, a plurality of VTOL rotors are divided into a plurality of groups, and each VTOL rotor is included in any one of the groups. After lift is generated by wings (a front wing and a rear wing), a controller sequentially stops rotation of the plurality of VTOL rotors on a group-by-group basis.

Vertical take-off and landing aircraft

A stacked core includes: a stack formed by stacking a plurality of blanked members and including a first end surface and a second end surface; a first distinguishing hole formed in the stack and being open at the first end surface; and a second distinguishing hole formed in the stack and being open at the first end surface. The spatial shape of the first distinguishing hole is different from the spatial shape of the second distinguishing hole.

Stacked core and method of manufacturing stacked core

A vehicle drive apparatus, including: an electric motor rotating about an axial line in a vertical direction, a first planetary gear mechanism of a single pinion type and a second planetary gear mechanism of a double pinion type arranged inside the electric motor, a torque transmission mechanism transmitting a torque output from the second planetary gear mechanism to a pair of drive shafts. The torque transmission mechanism includes a first torque transmission unit transmitting a torque output from a sun gear of the second planetary gear mechanism to one of the pair of drive shafts, and a second torque transmission unit transmitting a torque output from a carrier of the second planetary gear mechanism to the other of the pair of drive shafts.
