An aircraft has a fuselage, a wing assembly, and a pair of struts. The wing assembly has a center wing structure and a pair of outer wing structures. The center wing structure is coupled to the fuselage at a wing-fuselage joint, and has a pair of engine mounting locations respectively on opposite sides of a wing centerline. Each of the struts is coupled to the fuselage at a strut-fuselage joint, and to one of the outer wing structures at a strut-wing joint. Each strut-fuselage joint is located below and aft of the wing-fuselage joint. Each outer wing structure is coupled to the center wing structure at a mid-wing joint located no further inboard than the engine mounting location, and no further outboard than the strut-wing joint.

The invention discloses a propeller-driven helicopter or airplane which comprises a fuselage and a propeller comprising a plurality of blades, wherein a plurality of pressure pipes are uniformly distributed between windward sides and leeward sides of the blades; a plurality of first inlets are formed in the windward sides and are communicated with outside via first channels in the blades and second outlets at tails of the blades; a high-pressure fluid of a low-speed fluid layer formed when a fluid flows through the leeward sides in a widthwise direction flows towards a low-pressure fluid of a high-speed fluid layer formed when the fluid flows through the first inlets, the first channels and the second outlets; and an upward pressure generated by the high-pressure fluid is opposite to a downward pressure generated by an external fluid above the windward sides, so that a fluid pressure above the propeller is decreased.

A tandem wing aircraft that uses electric ducted fans to propel itself. The positioning of the electrical ducted fans allows the aircraft to take off and land vertically when the electrical ducted fans have their airflow outlet in a vertical position and to fly horizontally when a pair of electrical ducted fans are rotated so that their airflow outlet are in a horizontal position. The tandem wing aircraft uses an electric power source to power the aircraft and is controlled by a logic and electronic controller. The aircraft uses flaps, vertical stabilizers, ailerons, and an elevator to control its orientation and position during horizontal flight. The aircraft is designed to fly in urban spaces because of its wing and propulsion design. In addition, this design guarantees the stability of the aircraft on all flight stages, as well as the emergency landing in case the electrical ducted fans fail.

Embodiments described herein relate to a vertical take-off and landing aircraft, specifically an electric or hybrid electric aircraft having a plurality of ducted fans. The aircraft includes a plurality of axially oriented fans, laterally oriented fans, forward air intakes, side exit ports and rear exhaust ports. The aircraft achieves flight by capturing air in the intakes and diverting the air through the axially oriented fans or the laterally oriented fans through the channels selectively.

An integrated system for harvesting water from air includes an air propelling unit, a water condensation unit, and a fog harvester. The water condensation unit receives propelled air from the air propelling unit, and includes an airfoil designed to locally reduce pressure and temperature, thereby promoting water vapor condensation within the received propelled air. The fog harvester receives the propelled air with condensed water from the water condensation unit and collects the condensed water.
