The Heracles airship determines a new direction in airship construction by combining the buoyancy force and lifting force of a plane wing in its structure, thereby allowing the multiple increase of load-lifting capacity of the airship comparing to the known models while having comparable sizes.

The arrangement of solar panels on its upper semi-sphere provides energy independence, and time-unlimited remaining in flight makes it environmentally friendly.

It provides vertical ascending and landing, turning in a required direction, braking and maneuvering over a landing area on the ground and water.

In case of the emergency failure of the technical systems, safety systems are provided which allows using the airship for transporting large-tonnage loads and people.

A machine (10) with lifting system (18) includes a method for generating a resultant force (424) from circulating toroidal flow field (410) and poloidal flow field (420) within nearly confined toroid volume (413). The machine (10) architecture has designs for adaptability at assembly level to achieve modularity for ease of fabrication, maintenance, and operations.

An unmanned aerial vehicle according to the present invention may comprise: a rotor-blade for providing thrust according to generation of main stream; and a safety guard disposed to surround the rotor-blade. The safety guard may comprise: a guide member which is disposed coaxially with the rotor-blade while having a gap between the guard member and the end of the rotor-blade, so as to stabilize, when the rotor-blade rotates, a flow field suctioned by a negative pressure, and stably boost a discharge flow when the pressure is changed to a positive pressure; and a diffuser which is disposed coaxially with and radially spaced apart from the guide member, and generates a secondary flow toward the main stream to increase a flow rate.

The device is capable of transporting people and goods from one location to another: it includes a circular shaped body, a uniquely designed propeller mounted on the top of the body with propeller blades that produce a low pressure region above the device, the difference between the air pressure on the bottom and the top of the device's body provides the uplift force for holding the device in the air, capable of vertical takeoff and landing; on the surrounding wall, sideways and in back, service propellers are mounted in horizontal direction to help navigate the device; land and sea landing version of the device is disclosed as well; its bottom is extended in order to keep the doors above the water level during floating.

An aerodynamic lifting device comprises a chassis (200); a rotor (120) having a rotational axis (R) and a plurality of rotor blades (123) disposed in an annular ring about the rotational axis (R) supported by the chassis (200); and a torque transmission means (126,130,139) to provide tractive force for rotating the rotor (120). The torque transmission means (126,130,139) co-operates with at least one complementary and circumferentially extending drive surface (126a, 126b) of the rotor (120) to transmit tractive force as tangential forces and resultant torque sufficient to drive the rotor (120) and thereby generate lift. The aerodynamic lifting device may be used in airborne craft which may be deployed for waterborne use with a buoyant chassis (200), especially of toroidal shape, for elevating the rotor (120) above a water surface (300) during take off and landing.

Aerolift systems and methods using one or more air ducts and one or more lifting bodies. The duct may have a turn angle from the inlet to the outlet. The duct may have a variable cross-sectional area, such as increasing from inlet to outlet. The lifting body may be an airfoil. A propulsion unit, such as an electric motor and rotating blades, moves air through the duct and to the lifting body. The flow of air against and/or over the lifting body creates an aerodynamic lifting force. The flow of air downward may provide lift. The total lifting force may be used to move a moveable component. The aerolift system may be used in various applications, including aircraft and industrial systems. An aircraft may include the lifting body, or multiple lifting body segments, defining an annular shape, such as rounded or polygonal.

The herein invention is presenting a lift generating method based on a semi-open fluid jet flowing in a closed circuit around a lifting airfoil. A VTOL aircraft with maximized payload room and car-like shape is the preferred embodiment of the invention. The herein aircraft uses no wings, exposed propellers, hot gas jets or other high injury risk means for propulsion and lift, and it can be driven by ordinary skilled people. Furthermore the aircraft has a small footprint and can land, take off and even cruise on water in one of the preferred embodiments.

Provided is a drone with a wind guide part, which is configured such that it can lift off or aviate using the flow of wind. The drone has a lift force by wind discharged towards the ground through a connecting duct and a wind guide part, so that the drone may lift off or aviate using the flow of the wind. Further, the drone may aviate without a propeller, thus preventing an accident due to the contact of the propeller, saving maintenance cost, and reducing weight and noise.

A heavy lift airborne transport device is disclosed, which is capable of transporting people and goods from one location to another. The device includes a circular shaped body. A uniquely designed propeller is mounted on the top of the body. The propeller blades produce a low pressure region above the device. The difference between the air pressure on the bottom and the top of the device's body provides the uplift force for holding the device in the air. The device is capable of vertical takeoff and landing. A horizontally mounted propeller located at the back region of the device's body slightly lifts up the backside of the body, facilitating the forward movement for the device. A land and sea landing version of the device is disclosed as well.
