Manned/unmanned multipurpose aircraft with dual-mode taking off and landing

Abstract

By using dual-mode taking off and landing and a flight mode combined by two-layer lift fans and propeller propulsion, a manned/unmanned multipurpose aircraft with the dual-mode taking off and landing disclosed by the invention has many of the advantages owned by fixed-wing aircrafts and helicopters; in addition, the manned/unmanned multipurpose aircraft with the dual-mode taking off and landing has the advantages of good stability, higher flight speed, farther flying range, higher safety factor for occupants in the manned/unmanned multipurpose aircraft, vertical taking off and landing, short-distance or ultrashort-distance taxiing taking off and landing with multiple loading and carrying capacity, good maneuverability and other technical advantages. The design of the manned/unmanned multipurpose aircraft with the dual-mode taking off and landing is completely free of the traditional design mode of tilting rotorcrafts from the exterior to the overall layout and overcomes the shortcomings of rotors of the helicopters in high-speed flight and the dependence on airport runways of the fixed-wing aircrafts. The manned/unmanned multipurpose aircraft with the dual-mode taking off and landing can be applied to a wide variety of fields such as islands, reefs, ships, boats, border posts and the like, and also becomes an all-purpose novel military and civilian multipurpose aircraft.

Description

technical field [0001] Dual-mode lifting manned / unmanned multi-purpose aircraft, belonging to the field of aviation technology [0002] technical background [0003] At present, the only tilt-rotor aircraft produced and put into use in the world is the MY-22 "Osprey" tilt-rotor aircraft developed by the United States for many years. However, through its use process and the analysis of relevant data pictures, there are still many shortcomings and defects in this type of aircraft, such as poor balance ability when transitioning from vertical take-off to level flight or from level flight to vertical landing. Poor, complex conversion mechanism, large deflection rotor steering axis moment, small fixed wing, increased drag due to excessive rotor diameter during horizontal flight, high fuel consumption, and low safety factor. The dual-mode lifting manned unmanned multi-purpose aircraft is a new model with a new concept layout that has been researched to solve the problems existing ...
