Systems and methods for removeably adding a cargo bay floor to the interior cargo bay of cargo aircraft bay are disclosed. The system includes a rail disposed in a cargo bay of a cargo aircraft with the rail extending longitudinally along both a length of a forward portion and an aft portion of the fuselage. The system includes a cargo floor segment configured to be removeably attached to the rail. When attached, the cargo floor segment can transform between a first arrangement with the cargo floor segment translatable along the rail, and a second arrangement with the cargo floor segment fixedly secured to a location along the rail. The cargo floor segment is configured to, when secured to the rail, define a section of a floor of the cargo bay of the cargo aircraft. Multiple floor segments can be used together to form a continuous floor for the aircraft.

Aspects related to aircraft for commercial air travel and methods of manufacture. An aircraft includes a blended wing body, a single deck located within the blended wing body, wherein the single deck additionally includes a passenger compartment located in a lateral middle portion of the blended wing body and at least a cargo store located laterally outside the passenger compartment, and a landing gear, wherein the landing gear includes at least a nose gear located substantially forward of the single deck and at least a main gear located substantially aft of the single deck, wherein one or more of the at least a nose gear and the at least a main gear occupies a gear housing that overlaps with a plane coincident with at least a portion of the single deck.

A modular attachment device for insertion into a plurality of strands of a braided rope, comprising: at least one braiding segment that is braidable into the plurality of strands; at least one first lateral fixation segment that is mountable to the at least one braiding segment at a first lateral attachment interface; and at least one second lateral fixation segment that is mountable to the at least one braiding segment at a second lateral attachment interface, wherein at least one of the first and second lateral fixation segments comprises at least one anchor point for attachment of an external component, and wherein the first and second lateral fixation segments are mountable to the at least one braiding segment for securing the plurality of strands on the at least one braiding segment.

Systems and methods for operating an aircraft door including an airstair are disclosed. In one embodiment, the system includes a hinge configured to pivotally couple a lower portion of the door to a fuselage of an aircraft, a lift mechanism and an interlock. The lift mechanism causes a movement of the door relative to the hinge between a lowered position and a lifted position. The interlock is configurable between: a locked configuration where the movement of the door relative to the hinge is prevented; and an unlocked configuration where the movement of the door relative to the hinge is permitted.

The unmanned flying vaccine administration system comprises a drone, a vaccine delivery system, an interaction system. The drone is a vaccine injection flying robot that avoids the dangers of in-person vaccination. The vaccine delivery system is an electronic system that harnesses the power of technology to vaccinate people safely and efficiently. The interaction system is an electronic system armed with an Artificial Intelligence infrastructure. The present invention gathers energy by solar power, administers vaccines with a vaccine injection arm, and properly stores vaccines at the desired temperature with a storage container. The computing device controls the main modules that are designed for vaccine delivery and administration. The interaction system has a patient interface camera, a patient interface display, and a temperature sensor that monitor the state of the patient after receiving a vaccination to ensure the health and safety of the patient.

In one possible embodiment, a UAV payload module retraction mechanism is provided including a payload pivotally attached to a housing. A biasing member is mounted to bias the payload out of the housing and a winch is attached to the payload. An elongated flexible drawing member is coupled between the housing and the winch, the elongated drawing flexible member being capable of being drawn by the winch to retract the payload within the housing.
