Semi-annular-wing aircraft

Abstract

The invention discloses a semi-annular-wing aircraft. The semi-annular-wing aircraft comprises a steering engine, a propeller, a fuselage, an empennage and semi-annular wings connected with the fuselage, wherein the propeller is used for controlling a flight attitude through a controller; four sets of the semi-annular wings are arranged, and are symmetrically mounted at two sides of the fuselage;ailerons are arranged at edges of the semi-annular wings of a front row respectively; the propeller is correspondingly mounted above the semi-annular wings through a rotating device; the controller isused for controlling the angle of the propeller through the rotating device; the empennage comprises an elevating rudder and a yaw rudder; the elevating rudder is used for controlling a pitch attitude of the aircraft and the yaw rudder is used for controlling a yaw attitude of the aircraft. The aircraft provided by the invention is simple in structure; elevating force generated by the semi-annular wings is much greater than that of wings of a helicopter; the aircraft has the characteristics of great loading weight, rapid flight speed, far flying range, small noises, low energy consumption andthe like.

Description

technical field [0001] The invention relates to an aircraft, in particular to a semi-circular wing aircraft. Background technique [0002] An aircraft is a device that can fly in the atmosphere or outside the atmosphere (space). Aircraft mainly include rotors and fixed-wings, such as helicopters, fixed-wing aircraft, and multi-rotor aircraft. [0003] Because helicopters can take off and land vertically, they have very low requirements for takeoff and landing conditions, especially runways, so they are widely used, such as sightseeing, fire rescue, sea first aid, anti-smuggling and anti-drug, fire fighting, commercial transportation, medical assistance, communication and spraying Pesticides and insecticides are used in various sectors of the national economy such as eliminating pests and detecting resources. However, the disadvantages of helicopters are also obvious, such as small load capacity, low practical ceiling, and especially low speed, which also limits its range of...

Problems solved by technology

[0006] In the history of aviation, there has also been a semi-ring wing (Half ring wing) aircraft, which has a semi-ring appearance, which is equivalent to half of the ring wing, and is placed on both sides of the aircraft. Good lift, short take-off and landing advantages are very obvious, but due to various reasons, this semi-ring wing aircraft has not been widely used

[0007] In recent years, with the rise of the U.S. V22 Osprey tilt-rotor aircraft, countries are strengthening the research on tilt-rotor aircraft. V22 not only has the ability of ordinary helicopters to take off and land and hover in the air, but also has the ability of high-speed cruise flight of fixed-wing aircraft. Capability, the advantage is quite obvious, but the disadvantages of the V22 are also quite obvious, the structure is complex, the maintenance cost is high, the wing load is high, and the surplus power is insufficient during vertical take-off and landing, resulting in frequent failures
