Technical Field
The invention relates to an aircraft, in particular to an aircraft with an airfoil.
Background
In order to keep the helicopter such as a multi-rotor unmanned aerial vehicle flying in the air, the lift force can be provided only by driving the rotor to rotate, the energy consumption is very high, and if the helicopter can utilize the airflow lift force like a kite in the air, the helicopter can be kept to be suspended in the air only by consuming little energy. The invention is to install a set of kite-like wing surfaces capable of being folded and unfolded on an aircraft, so that the wing surfaces can be unfolded when needed in flight, air flow can be better utilized, the endurance time is prolonged, the energy consumption is saved, and the risk of crash can be reduced.
Disclosure of Invention
The invention relates to a manned or unmanned aircraft with an airfoil.
The technical scheme adopted by the invention comprises the following components: a multi-rotor (prop) craft or helicopter body; winged or kite-like airfoils (hereinafter referred to as airfoils); an airfoil deployment and stow or fold assembly; a mechanism (hereinafter referred to as a rotor steering engine) which can rotate the rotor (propeller) assembly by a certain angle to change the thrust direction.
The scheme is mainly characterized in that:
1. the aircraft is provided with wing surfaces which can be made of any appropriate material and shape, so that the aircraft can take off and land vertically, can fly like a common parachute-wing aircraft or a fixed-wing aircraft and can also take off and land in a sliding mode.
2. According to the demand, can select to adopt the airfoil to accomodate, expand or folding assembly, steerable airfoil is accomodate or expand when needs, can reduce the windage when accomodating, promotes the anti-wind ability, increases hover stability to improve vertical take-off and landing speed, and the airfoil can utilize the air current to provide lift for the aircraft when expanding, can realize the landing of leaping, improves the speed of flat flight, the energy can be saved, this receive and release process even can also realize at the flight in-process.
3. According to the demand, the rotor steering engine can be selected, the angle formed by the rotor (propeller) component and the fuselage is controlled through the rotor steering engine, the fuselage is supposed to be parallel to the ground, the rotor steering engine is controlled to enable the rotor (propeller) component to be vertical to the fuselage upwards, and the rotor (propeller) component can also be forward in the same direction as the fuselage or rotate to other required angles, so that the thrust direction is changed.
4. According to the requirements, the folding and unfolding components of the airfoil surface and the airfoil surface can be designed to be detachable, so that the aircraft can fly even if the folding and unfolding components of the airfoil surface and the airfoil surface are not installed.
In view of the above-mentioned features, some design examples will be shown in the following, but the scope of the present invention is not limited to the following examples, and the same numbered parts in all examples have substantially similar functions even though they may be different in shape and form.
