DESCRIPTION

UNMANNED BIRD AIRCRAFT WITHOUT SURFACES

VERTICAL

OBJECT OF THE INVENTION

The present invention refers to an aircraft, mainly unmanned, with a wing and a fuselage or body in a mimetic shape to that of a bird in flight, preferably that of a raptor, whose tail has an open U geometry that provides three aerodynamic planes, one horizontal and two oblique, for stabilization in the three axes of the aircraft, without the need to incorporate vertical surfaces, and incorporating an autonomous take-off, navigation and landing system.

It comes to propose a solution as a substitute for a deterrent bird in an environment where other birds are a problem, such as in airports, wind farms, landfills, etc., solving the problem of lack or loss of realism in mimicry with birds in flight due to use vertical surfaces in the tail of the aircraft, while the present invention makes it possible to achieve a total governability in the three axes of the aircraft hitherto not achieved with the current configurations of aircraft without tail empennage of the "flying wing" type.

It can also be used as a surveillance drone or unnoticed observation of perimeters and areas of security, traffic, military, fire, etc. in real time, since it is mistaken for a bird in flight and does not generate visual impact.

In addition, it operates completely autonomously both during takeoff and landing and in the flight itself, being able to be remotely activated from a radio signal, which can be sent from a radar or artificial vision system whose sensors capture the presence of birds in the zones and areas described above, and can also be activated manually or semi-automated by programmed alarm.

It can perform circular flight patterns in upward air currents (further simulating biomimicry), in addition to saving considerable energy for its propulsion, which also translates into long range and long flight times.

Other advantages of this invention derived from the absence of vertical surfaces on wings or fuselage would be:

- A total stabilization and governance in the three axes of the aircraft without using vertical surfaces in the tail of the aircraft.

- An increase in autonomy due to the elimination of aerodynamic interference that would take place in the joints of the tail or wing surfaces of the “T” type.

- Greater operational robustness due to the elimination of protruding horizontal tail surfaces or vertical “T” type surfaces, which would result in damage or breakage due to impacts on said protruding surfaces during landing.

- An enormous simplicity of operation by allowing takeoff by launching ramp with an anchoring system to the fuselage without producing mechanical interference or impact with the stabilizer surfaces, although it can also take off by launching by hand.

The industrial application of this invention is within the field of autonomous flight machines and devices, and more specifically aircraft shaped like birds, without vertical surfaces.

BACKGROUND OF THE INVENTION

Although no invention identical to that described has been found, we present below the documents found that reflect the state of the art related thereto.

Thus document JP2003304795A refers to an artificial wing and wire device equipped with a bilateral rack gear and a semicircular gear that the shape of the bird is the part of the beveled head and the part of the body that is fastened with screws and the part of the head can move, and the non-moving part can also be an integral form, the semi-circle gear that engages the rack gears. both sides attached to the cavity part of this body from the left and right sides Large blades are attached to the attached wing or connecting plate with semi-circular gears, the transmission rod is passed and fixed to the top of the rack gears on both sides, and then the rack gears on both sides are horizontally placed in the middle with an elliptical hole. It is equipped with a guide that drives vertically and prevents lateral movement from the left and right, and it also has a semi-circular gear that engages with rack gears on both sides that drive from both sides. A surface rack gear. It is therefore a device with wings and the shape of a bird that contains a gear mechanism that simulates the movement of the wings, but does not include any system or impulse mechanism to maintain a flight like the unmanned aircraft proposed by the main invention. .

ES2385183T3 proposes a VTOL aircraft flight wing in which a pair of thrust vectoring propulsion units are mounted on each of the opposite ends of the wing structure laterally forward and rearward of the aircraft axis and each unit force vectoring propulsion system operable to selectively and variably direct the thrust produced between downward for takeoff and backward for forward flight, characterized by the fact that a single pair of propulsion units is mounted on each one of the opposite ends of the wing structure, and the two drive units of each pair are equidistantly spaced respectively forward and rearward of the aircraft's center of gravity. In this case, a flight wing with propulsion units at its ends is described, which does not comprise any shape that simulates the silhouette of birds in flight, therefore it does not affect the novelty or inventive activity of the main invention.

CN201563537U claims a crop protection device that includes a bionic model and a pager. Said device does not specify the shape of the model or the exclusion of vertical surfaces, object of the main invention to mimic even more as a bird.

Conclusions: As can be seen from the research carried out, none of the documents found solves the problems raised as the proposed invention does.

DESCRIPTION OF THE INVENTION

The unmanned trichola bird aircraft without vertical surfaces object of the present invention is constituted from a wing and a fuselage, where the end of the fuselage, seen from the trailing edge and towards the nose, acquires the geometry of a "U" open, so that the surfaces projected in both horizontal and vertical lateral planes of the aircraft, offer three stabilizing surfaces: (i) an equivalent horizontal stabilizer surface similar to a minor side isosceles triangle located on the trailing edge of the fuselage, and (ii) two oblique surfaces, or a double equivalent vertical stabilizer surface, similar to two identical right triangles, such that the most acute vertex of both triangles is oriented towards the nose of the fuselage, and the other acute vertex of the triangle is oriented preferably upwards.

In the fuselage, in the central part of the tail seen in plan, there is primarily a horizontal movable surface that acts as a depth control.

In a different embodiment, on the double equivalent surfaces of the vertical stabilizer, oblique movable surfaces can be provided that act in combination as a depth control, and / or turn control, and / or roll control.

In the nose of the fuselage there is a motor, primarily electric, although in some embodiment a motor could not be included in the nose of the fuselage, but two motors, each one located at the most forward leading edge point of each wing.

In a different embodiment, the propeller blades of the engine can be folded back.

At the bottom of the fuselage, there is primarily a hull segmented by a horizontal plane where the energy storage battery is housed.

Each of the half blades has a double arrow on the leading edge and a break point on the trailing edge, so that, in the inner half of each semi-wing, the leading edge has a negative arrow, causing the leading edge of the wing profile of the central area of the wing to be ahead of the wing profile located near the fuselage. And in the outer half of each wing, the leading edge has a positive arrow so that the leading edge of the marginal wing profile is set back with respect to that of the central area of the wing. Likewise, in the outer half of each wing, the trailing edge primarily has a positive arrow so that the trailing edge of the marginal wing profile is set back with respect to that of the central area of the wing.

In the semi-wings, preferably in each of their outer halves, there are ailerons located on the trailing edge.

In a different embodiment, the area of the nose of the fuselage, on each side of the fuselage and in front of the leading edge of the central wing profile, as well as below the midline thereof, can primarily have two short bayonets or lugs, with the function of serving as a hitch and push point to take off from a catapult or shuttle.

And in other different embodiments, the aircraft object of the present invention incorporates the following elements and / or combinations of these: at least, a camera, a parachute, a landing airbag, and, at least, a speaker for emitting squawks.
