Abstract: A system is disclosed to detect failure of a diode that is connected in series with a battery and a contactor or other switch configured to connect the battery to a load when the contactor or other switch is in a closed position and to isolate the battery from the load when the contactor or other switch is in an open position. In various embodiments, the system includes a high value resistor connected between the anode terminal of the diode and ground, the connection to the anode terminal being on a load side of the contactor or other switch; and a voltage meter configured to measure a voltage across the high value resistor at least during a test in which a voltage is applied to a bus associated with the load while the contactor or other switch is in the open position.

Abstract: A power distribution circuit for an electrically powered aircraft includes a plurality of batteries and a plurality of electric propulsion systems. A plurality of isolated power distribution circuits each couple a battery of the plurality of batteries to two or more electric propulsion systems. The plurality of electric propulsion systems are positioned on the aircraft to apply balanced forces to the aircraft such that in the event of a failure, the aircraft remains stable and only experiences a loss in altitude or speed.

Abstract: Embodiments provide a propeller ground stop mechanism configured to keep an unpowered propeller of an aircraft (e.g. when the aircraft is on the ground and not operating) static. The propeller is prevented from rotating due to external forces (e.g. an air flow caused by wind, manual rotation of the propeller). When the propeller is powered, and the propeller is providing thrust, the propeller ground stop mechanism automatically disengages and does not provide any drag. Among various benefits, the propeller ground stop mechanism provides added safety to the ground support personnel.

Abstract: An electrically powered vehicle includes a plurality of batteries and a plurality of DC to DC converters, each coupled to a respective battery of the plurality of batteries. Each DC to DC converter transfers power from a respective battery to a common DC bus. The common DC bus is coupled to a plurality of inverter circuits that convert the DC power to AC power. A plurality of electric motors receive power from the plurality of inverter circuits to propel the vehicle. During a regenerative event, the DC to DC converters can transfer power from the motors back to the batteries. In response to the failure of a battery, the DC to DC converters can isolate the remainder of the system from the failure.
