The present Invention of Air Cycling Aircraft is a double cycling mechanism or double mono wheel bikes whose mechanism is designed for locking in and out should one cyclist desire to take a rest. The double cycling system also ensures long cycling distances. The system mainly comprises a fuselage, wheels, double cycling structures or mono wheel bikes, linear wheel, twin arm gearbox, propeller shaft and propeller. The invention mainly addresses cycling structures, navigation or steering system, cycling friction, and high speed. Motion transmission system is developed into three stages, primary, secondary and advanced stage, to enable the twin arm gearbox to generate more than 2,000 rpm and transmit to the propeller. The present invention the new Air Cycling Aircraft is environmentally compliant and can be used for leisure flying, passenger and air sporting.

The present Invention of Air Cycling Helicopter is a double cycling system with independent speeds. The mechanism is designed for locking in and out should one cyclist prefer to take a rest. The system comprises fuselage double mono wheel bikes, motion transmission mechanism, twin arm gearbox, vertical shaft, rotors and skis. The mono wheel bikes and the motion transmission system, which is developed into three stages, primary, secondary and advanced stage, transmit more than 1,800 rpm to the rotors. The present invention of Air Cycling Helicopter is environmental friendly and revolutionary in helicopter manual flying. The principal use of the present invention is for leisure flying and Air sporting.

A human powered aircraft has a fuselage in which a nacelle is defined, at least one wing fastened to the fuselage, at least a first propeller adapted to rotate about a first propeller axis, and a propeller group configured to be operated by a user to rotate the at least a first propeller about the first propeller axis. The propeller group has a first propulsor and a second propulsor adapted to be moved by upper limbs and lower limbs of the user, respectively. The first and second propulsors are configured to be rotated alternatively in two opposite directions about a first rotation axis and a second rotation axis, respectively. At least one connection arm connects the first and second propulsors to each other so that a rotation in one direction of the first propulsor results in a rotation in the same direction of the second propulsor, and vice versa.

The utility model provides entertainment fitness equipment with a bionic flapping wing flying structure, which is characterized in that a seat is arranged in a main frame, and flapping wings extending outwards are respectively hinged to the left side and the right side of the main frame above the seat; each flapping wing is formed by hinging a wing middle plate and a wing tail plate; the wing middle plate and the wing tail plate are provided with air holes with one-way valve plates; the main frame is provided with two upper fixed pulleys and two lower fixed pulleys, one end of an upper pull rope is connected to an upper hanging lug of a wing tail plate, and the other end of the upper pull rope is connected with a hand-pulled hanging ring after bypassing the upper fixed pulleys. One end of the lower pull rope is connected to the lower hanging lug of the wing tail plate, and the other end is connected with the pedal hanging ring after bypassing the lower fixed pulley. When the device is used, the device is hung below the large rotor unmanned aerial vehicle, an operator sitting on the device seat pulls the flapping wings on the left side and the right side to swing up and down in a mode of alternately contracting and stretching four limbs, so that the device obtains certain flight assistance, the carrying capacity of the unmanned aerial vehicle can be reduced while entertainment and fitness are carried out, and the device is convenient to use. And the cruising ability of the unmanned aerial vehicle is improved.

This invention discloses a human-powered flywheel hybrid propulsion system and aircraft, belonging to the field of human-powered aircraft technology. The system includes: a human input mechanism receiving the user's pulling force; a flywheel energy storage and speed-up mechanism connected to this mechanism via a traction rope, which incorporates a flywheel body and a one-way clutch to achieve unidirectional kinetic energy transmission; a power synthesis and transmission mechanism connected to the output end of the flywheel mechanism, which synthesizes and outputs the flywheel's power; and a propeller connected to the power mechanism. The human input mechanism employs an alternating left-right pulling design, simulating the movement of pulling a rope to save effort. The flywheel is made of carbon fiber and can be quickly charged with a hydraulic starting device. A differential gearbox is preferred as the power synthesis mechanism. This propulsion system is suitable for aircraft such as fixed-wing gliders, which feature a high monoplane configuration, a high aspect ratio wing, and a lightweight carbon fiber structure, with strict weight control to adapt to the power requirements of different flight phases.
