Abstract: A system for maintaining a fleet of aircraft batteries located at multiple airports. The system may be configured to obtain charge information and battery health information for individual batteries within the fleet of aircraft batteries from charging containers located at individuals ones of the multiple airports. The charge information may include charge statuses of the individual batteries and/or the battery health information may characterize the degradation of the individual batteries over time. The system may determine predictions of one or more batteries to be re-allocated and/or to receive maintenance based on the battery health information. The system may generate a battery management plan including the one or more predictions recommending one or more batteries to be re-allocated and/or to receive maintenance.

Abstract: A parallel hybrid aircraft comprising an electric propulsion system and a combustion propulsion system. The electric propulsion system may include a motor, one or more batteries, and a first propeller. The combustion propulsion system may include a combustion engine and a second propeller. The combustion propulsion system may be decoupled and independently operable from the electric propulsion system. A flight control system may control which of the electric propulsion system and/or the combustion propulsion system provides propulsion and/or thrust for ground movement, takeoff, forward flight at cruising altitude, and/or landing.

Abstract: A latching mechanism is provided for engaging an aircraft surface panel to a support member. The aircraft panel is provided with a post extending from the lower surface, which extends through a panel support member into a post engagement mechanism. The post engagement mechanism defines a rotatable sleeve, which rotates for locking and unlocking engagement between the post and the post engagement mechanism. Locking engagement continues when power to the post engagement actuator is terminated. The post engagement mechanism may utilize various types of actuators, including mechanical, hydraulic, and pneumatic. The aircraft panel and the panel support member are translatable into and out of abutting engagement independent of the need for any contact with the aircraft panel upper surface.

Abstract: A pneumatic fastening mechanism is provided for fastening an aircraft surface panel to an aircraft panel support member. The panel includes a plurality of receptacles extending from the panel lower surface. The panel support member includes a corresponding plurality of panel engagement mechanisms, disposed on the support member lower surface, and translatable through the support member to engage the receptacles. The panel engagement mechanisms are extendable from a first position, wherein the panel abuts and is engaged to the panel support member, to second position wherein the panel is elevated above the panel support member upper surface where the panel may be unlocked and separated from the panel engagement mechanism. The panel engagement mechanism is operative to elevate and release the panel in response to changes in fluid pressure communicated to the panel engagement mechanisms.
