The present invention discloses a vertical take-off and landing triphibian flight vehicle, which can travel in land, water and air. The triphibian vehicle is based on the structure of an ordinary electric automobile. Its airscrew module is stored in the front and rear spaces of the triphibian vehicle body. The triphibian vehicle has land mode, air mode, water mode. These three modes are achieved by the positional changes of the airscrew module. The triphibian vehicle does not require the runway, which can take off and landing vertically. Its self-powered power supply provides the unlimited power to the triphibian vehicle itself, eliminating the need for charging, and no mileage restrictions.

A convertible ducted fan engine having a shroud, a drive shaft connected to a mechanical fan, and a rotational drive motor configured to rotate the mechanical fan. An embodiment includes a linear drive motor configured to translate the drive shaft and mechanical fan in a direction parallel to a longitudinal axis of the shroud. The convertible ducted fan engine includes a fluid-propulsion configuration in which the mechanical fan rotates freely with respect to the shroud to produce thrust through fluid flow, and a drive-wheel configuration in which the shroud rotates about the rotational axis.

A field configurable autonomous vehicle includes modular elements and attachable components. The vehicle can be assembled from these modular elements and components to meet desired mission and performance characteristics without the need to purchase specially designed vehicles for each mission. The vehicle can include a modular propulsion system with magnetic drive.

A UAV with vertical takeoff and landing (VTOL) function having a plurality of lift propellers; a cabin engaged with a plurality of lift propellers; a water propulsion system engaged with the cabin to push the cabin in a forward direction when the cabin is at least partially immersed in water; at least one water inlet engaged with the water propulsion system; the cabin is a cargo hold or a passenger cabin. The UAV provided by the disclosure can realize vertical takeoff and landing in the water area, and fly, drive and navigate freely in the whole area.

A submergible aerial vehicle with one or more rotors, a body operatively connected to the one or more rotors, and a platform operatively connected to the body. The vehicle is configured to operate with one or more additional vehicles such that the platform of each vehicle connects together and forms a segment of an enlarged floating platform. The enlarged platform is configured to support an object above the water. The body includes a cavity that is able to be at least partially filled with fluid. The cavity causes the submergible aerial vehicle to be at least partially submerged in a body of water.

An example wing-in-ground effect vehicle includes (i) a main wing having main wing control surfaces; (ii) a tail having tail control surfaces; (iii) a blown-wing propulsion system arranged along the main wing or the tail; (iv) a retractable hydrofoil configured to operate in: (a) an extended configuration in which the retractable hydrofoil extends below a hull of the vehicle for submersion below a water surface and (b) a retracted configuration in which the retractable hydrofoil is retracted at least partially into the hull of the vehicle; and (v) a control system configured to maneuver the vehicle by (i) causing a change in orientation of the retractable hydrofoil when the retractable hydrofoil is operating in the extended configuration, and (ii) causing a change in orientation of the main wing control surfaces and tail control surfaces when the retractable hydrofoil is operating in the retracted configuration.

A system for transporting one or more items is provided. The system includes: a transportation tube disposed at least partially underground or at least partially above ground; a transportation pod to secure items therein for transport; a transportation actuator to propel the transportation pod through the transportation tube, the transportation actuator including at least one cable configured to interface with the transportation pod, the at least one cable being driven by a motor to move the cable and the transportation pod through the transportation tube; a first access point located proximate a first end of the transportation tube; and a second access point located proximate a second end of the transportation tube. Each of the first and second access points includes an opening configured to allow the transportation pod to be received into or removed from the transportation tube.
