Abstract: An operator tag search system can generate a search page including a search box and identify an initial set of user inputs in the search box. The search system can generate operator tags in the search box, where each operator tag includes a selected search property, an operator, and an inputted value. The search system can perform a dynamic search in one or more databases to satisfy each of the operator tags. Based on the dynamic search, the search system can generate a results feature for display on the search page.

Abstract: The disclosure generally relates to aircraft vehicles, specifically vertical takeoff and landing (VTOL) aircraft that include propellers. A propeller is coupled to a boom and the boom includes a boom control effector. The boom control effector is configured to direct the airflow behind or below the propeller. The boom control effector can be configured to control the yaw movement of the aircraft and mitigate noise from the propeller. A boom control effector can be a single effector or a split effector. The split effector may operate in conjunction with a boom that operates as a resonator to reduce noise produced by the propeller.

Abstract: An aircraft can include a stacked propeller to generate lift during assent and descent. The stacked propeller includes a first propeller and a second propeller that co-rotate about an axis of rotation. In one embodiment, the blades are coupled to a rotor mast that contains an internal cavity. In one mode of operation, the first propeller and/or the second propeller can be stored in the internal cavity in order to reduce drag during flight. The aircraft can include one or more stacked propellers, such as a port propeller and a starboard propeller, which rotate in opposite directions during one or more modes of flight.

Abstract: A vertical landing and take-off aircraft VTOL transitions from a vertical takeoff state to a cruise state where the vertical takeoff state uses propellers to generate lift and the cruise state uses wings to generate lift. The aircraft has an M-wing configuration with propellers located on the wingtip nacelles, wing booms, and tail boom. The wing boom and/or the tail boom can include boom control effectors. Hinged control surfaces on the wings, tail boom, and tail tilt during takeoff and landing to yaw the vehicle. The boom control effectors, cruise propellers, stacked propellers, and control surfaces can have different positions during different modes of operation in order to control aircraft movement and mitigate noise generated by the aircraft.

Abstract: A vertical take-off and landing (VTOL) aircraft provides transportation to users of a network system. The network system may include multiple aircraft or other types of vehicles to provide multi-model transportation. An aircraft may include a fuselage, a truss coupled to the fuselage, and multiple distributed electric propellers coupled to the truss. The distributed electric propellers may be positioned on at least two different planes. The fuselage may include a cabin having one or more seats for the passengers arranged in a configuration that has a compact footprint, provides legroom, provides visibility to surroundings of the aircraft, or facilitates convenient ingress or egress of passengers. The aircraft may open a port cabin door and starboard cabin door for simultaneous ingress or egress of passengers.
