Hi, my name is Navi Wright, I am SM Aeronautical Engineer in my company 1781navi, Aircraft Innovation.
My innovation can save around 10% energy in vehicles and homes, and can be easily integrated. I have done tests with a drone, a prototype car and a prototype house with positive results. The matt black paint of cars, motorcycles, etc. that you see on the streets is my invention. You can read my innovation:
The invention relates to a sustainable painting system for aircraft that mimics the anatomy of a peregrine falcon, reduces the impact of aircraft against birds and flying insects, improves aerodynamics and harnesses solar and wind energy. The surfaces painted in matt black (1) and (6a), due to their composition and color, are negatively electrified due to friction with air by the triboelectric effect, and absorb electromagnetic radiation, heating up. The opposite occurs with the surfaces painted in glossy white (2) and (6b); which are positively electrified and cool down. This different electrification and heating of the surfaces produces electrical forces and transfers the energy to the air flow, so as to increase the lift and improve the aerodynamics of the vehicle. The appearance of a falcon, swallow or bat frightens birds and flying insects, respectively. The invention is mainly intended for aircraft, vehicles and wind turbines.
SECTOR OF THE TECHNIQUE
The present invention belongs to the field of aerodynamics and renewable energies, mainly and specifically that of aircraft paint systems.
The object of the present invention is a sustainable paint system for aircraft, which mimics the anatomy of a peregrine falcon; It reduces the impact of aircraft against birds and flying insects in their movement, improves aerodynamics and also takes advantage of solar and wind energy.
BACKGROUND OF THE INVENTION
A problem that airplanes, vehicles and wind turbine blades have in their movement through the air is the impact against birds and flying insects. Although the large passenger aircraft and their engines are prepared for the collision in flight against large birds; This type of collision poses a risk to flight safety, has caused serious air accidents, and is also an environmental problem. In addition, the impact against flying insects dirties the leading edges of wings and blades, as well as the nose of aircraft and vehicles; causing significant losses of aerodynamic performance. Another environmental problem presented by current aircraft and vehicles is the emission of pollutant gases from their engines, which work thanks to the combustion of fossil fuels.
World War II planes were painted dark colors on top and light colors on the bottom but all matte and for camouflage purposes. In the “Nose Art “or Art in the Nose, paintings or designs of animals appear on the nose of the aircraft, but for decorative purposes or to intimidate the enemy. There are currently military aircraft that are painted black, but as camouflage color at night or to make them invisible to the radar. Most civil aircraft and wind turbine blades are painted white or light colors, primarily to avoid overheating and improve their visibility; but precisely light colors worsen their visibility in bad visibility conditions, that is to say, with fog or when they are inside clouds, since they blend in with them. There is currently no sustainable paint system for vehicles, which reduces collisions with birds and flying insects, and that takes advantage of solar energy and wind in the way the present invention does.
EXPLANATION OF THE INVENTION
The present invention reduces the collisions of moving bodies through the air, with birds and flying insects. It also improves the aerodynamics of body surfaces and allows the harnessing of solar and wind energy. For the explanation, an airplane is taken as an example and reference body, which is the preferred application of the present innovation.
Hereinafter in the description, to make the explanation more clear and concise; when speaking of black, it will refer to a matt black and/or dark color, and when speaking of white, it will refer to a bright white and/or clear color.
The upper surfaces and the extradoses, with black paint and thanks to its composition and color; they become negatively electrified due to their friction with the air by triboelectricity, and absorb electromagnetic radiation. On the contrary, the lower surfaces and the intradoses, with white paint, also due to their composition and color; they become positively electrified when they rub against the air and reflect electromagnetic radiation. This different electrification of the surfaces can be used to accumulate electrical energy and/or charge electrical batteries.
Matte paint contains a matrix and matte pigments. Glossy paints contain a matrix and shimmering pigments.
The surface finish of the matt paint layers is rougher than that of the gloss paint layers. On the upper surfaces and on the extradoses, black; Being in the sun, due to the absorption of electromagnetic radiation and the greater friction with the air, the surfaces heat up. This heat can be transferred to the boundary layer to improve aerodynamics, and/or it can be conducted through the surface, and transferred to a coolant for later use. On the contrary, on the lower surfaces and on the intradoses, white; Being in the shade, due to the reflection of electromagnetic radiation and less friction with the air, the surfaces cool down. This cold can be transferred to the boundary layer to improve aerodynamics, and/or it can be conducted through the surface, and transferred to a coolant for later use.
On the other hand, the compositions of the paints are such that; the surfaces of the upper layers and extradoses, black in color, are hydrophobic. And on the contrary, the surfaces of the lower layers and intradoses, white in color, are hydrophilic. This allows the water in the airflow to be directed around the body, preferentially towards the lower surfaces and intradoses, improving lift and aerodynamics.
The black color of the upper surfaces and extradoses contrast with the white of the clouds and fog, improving visibility and safety.
Gusts and extreme winds are a problem in aircraft, vehicles and wind turbines; giving rise to extreme loads and fatigue on the bodies. The paint system allows driving and taking advantage of wind energy; creating hard and easy flow surfaces in the upper and lower body areas respectively. A similar behavior occurs on the extradoses and intradoses of wings, blades and blades. Like an aerofoil, the two oppositely painted surfaces modify the airflow; because the surfaces interact with the boundary layers and this information travels upstream at the speed of sound, modifying the fluid field. In the aerodynamic profiles there is an acceleration and deceleration of the air in the extrados and intrados respectively. The sum of these two effects translates into an increase in circulation, and therefore also increases lift and aerodynamic efficiency. The present invention makes it possible to take advantage of wind energy thanks to the phenomenon of triboelectricity, as explained above.
A bird flying through the air may collide with a plane because the bird does not see it coming, or because it does not have time to avoid it due to the high speed of the plane. The same thing happens to the pilot of the plane. The paint system of the invention in question gives the aircraft the appearance of a peregrine falcon, so that a bird flying on a collision course ahead of the aircraft has the impression of seeing a falcon flying towards it. stalking it, the bird feels threatened and flies out of the plane’s path. In the case of flying insects, the operation is similar; the vision of insects is diffuse, so the insect will have the impression of seeing a black bird, a swallow or bat that is stalking it, and it also flees from the collision path when feeling threatened. In addition, current civil aircraft, which are painted in bright colors, produce greater reflections or reflections of electromagnetic radiation; including the reflection of solar radiation, and specifically the reflection of infrared and ultraviolet radiation. These radiations, instead of frightening, can further attract flying insects that are swarming in the path of the aircraft; increasing the number of collisions, fouling the leading edges of wings, the nose of the fuselage and engines. This dirt accumulates and is aggravating, increasing aerodynamic resistance and reducing engine performance. To give the body the appearance of a peregrine falcon; the upper half of the body is painted black and the lower half of the body white. The lower front part of the body or nose is painted with an ogival shape in a horizontal position, in black and simulates the opening of the open beak of a falcon. The surface surrounding the anterior ogival shape is painted as a bright yellow frame. On each upper front side a round eye is painted in black, surrounded by a bright yellow eye ring. On the sides of the front part of the body, a vertical stripe is painted on each side in black that simulates the whiskers. If the body has wings, blades or blades; the extradoses are painted black and the intradoses white. Except surfaces that function as inverted wings such as aircraft tail horizontal stabilizers or automobile spoilers; then the upper surface is painted black and the lower surface white. The cones of the propellers are painted black.
The present invention creates a zone of higher energy and another of lower energy in the upper and lower surfaces respectively; the upper surfaces have more energy because they are hotter, higher, and charged with electrons, the lower surfaces have lower energy because they are cooler, lower, and charged with protons. The molecules of the air currents that surround the body tend to flow preferentially through the areas of lower energy, increasing aerodynamic lift. There is an additional acceleration and depression in the air flowing at the top, and an additional deceleration and overpressure in the air flowing at the bottom; that is, in a wing the lift effects that are produced in an aerodynamic profile without the characteristics of the invention are increased. Thanks to the increase in lift, an aircraft can decrease its angle of attack and therefore also decreases the induced aerodynamic drag, improving aerodynamic efficiency.
