ÁMBITO TÉCNICOTECHNICAL SCOPE
Esta invención tiene su aplicación dentro de la industria dedicada a la fabricación de aeronaves tales como los planeadores, motoveleros, o aviones de época, dentro del mundo de la aviación deportiva; adicionalmente, la invención también encuentra aplicación inmediata en la industria de fabricación de aeromodelos .This invention has its application within the industry dedicated to the manufacture of aircraft such as gliders, motorboats, or vintage aircraft, within the world of sports aviation; Additionally, the invention also finds immediate application in the aircraft manufacturing industry.
TÉCNICA ANTERIORPREVIOUS TECHNIQUE
Volar de forma autónoma y respetuosa con el medio ambiente, es la ilusión de todo piloto deportivo. De todos es sabido la problemática existente en los planeadores y motoveleros, cuando pierden demasiada altura lejos de la pista, viéndose obligados a aterrizar en campos a veces desconocidos, con el coste que ello conlleva, además del riesgo para la integridad física de los pilotos.Flying autonomously and respectfully with the environment is the illusion of every sports driver. Everyone knows the problem in the gliders and motorboats, when they lose too much height away from the track, being forced to land in sometimes unknown fields, with the cost that this entails, in addition to the risk to the physical integrity of the pilots.
Es conocido el uso de células solares para abastecimiento de energía a satélites u observadores meteorológicos, como el prototipo Helios desarrollado por la NASA, careciendo todos ellos de tripulación y de aplicación deportiva.It is known to use solar cells to supply energy to satellites or meteorological observers, such as the Helios prototype developed by NASA, all lacking crew and sports application.
Se conocen varios intentos de aprovechar células fotovoltaicas para alimentar motores eléctricos en aeronaves tipo motovelero, basados en el pegado de las células sobre la superficie exterior del avión. Más concretamente, a través de los documentos ES-1032532U, US- 4697761A, GB-2328657A, US-3658596A, US-5518205A, US- 4415133A, JP-4005198A, DE-2616000A y JP-10119896A se conocen sistemas generadores de energía de este tipo.Several attempts to harness photovoltaic cells to power electric motors in motor-type aircraft are known, based on the gluing of the cells on the outer surface of the aircraft. More specifically, through documents ES-1032532U, US- 4697761A, GB-2328657A, US-3658596A, US-5518205A, US- 4415133A, JP-4005198A, DE-2616000A and JP-10119896A are known power generation systems this type.
Estas soluciones tiene grandes inconvenientes, dado que, las células fotovoltaicas van pegadas o adheridas sobre la superficie exterior del avión afectando directamente a la aerodinámica de la aeronave; además esta solución exige proporcionar células flexibles producidas de forma muy especifica según el perfil sobre el que deben adherirse y, la exposición a la luz del sol difícilmente es completa, por la distinta orientación de las células según su ubicación sobre las distintas superficies .These solutions have great disadvantages, given that the photovoltaic cells are glued or adhered to the exterior surface of the plane directly affecting the aerodynamics of the aircraft; This solution also requires providing flexible cells produced in a very specific way according to the profile on which they must adhere and, exposure to sunlight is hardly complete, due to the different orientation of the cells according to their location on the different surfaces.
La solución a esta problemática, seria la de contar con un dispositivo generador de energía que, o bien, proporcione la energía directamente al motor, o bien, recargue sucesivamente baterías correspondientemente previstas que alimentan el motor eléctrico, sin que su peso, forma, tamaño, disposición o condiciones de funcionamiento, impidan el despegue o correcto comportamiento en vuelo de la aeronave.The solution to this problem would be to have an energy generating device that, either, provides energy directly to the motor, or, recharge successively correspondingly provided batteries that power the electric motor, without its weight, shape, size, arrangement or operating conditions, preventing the take-off or correct flight behavior of the aircraft.
Por otro lado, seria deseable, poder usar células fotovoltaicas comerciales, semielaboradas, sin exigir una producción de características especificas, y cuyo uso modular y adaptable, abarate su producción, haciéndolo aplicable incluso a planeadores, aeromodelos o aviones de época ya fabricados, con pocas modificaciones.On the other hand, it would be desirable, to be able to use commercial, semi-finished photovoltaic cells, without requiring a production of specific characteristics, and whose modular and adaptable use, reduce their production, making it applicable even to gliders, airplanes or vintage aircraft already manufactured, with few modifications.
De conformidad con todo ello, subsiste la necesidad de proporcionar un sistema para generación de energía para aeronaves a base de células fotovoltaicas que permita solucionar los' problemas de la técnica anterior.In accordance with this, the need remains to provide a system for generating energy for aircraft based photovoltaic cells that allow solving 'problems of the prior art.

Las planchas de material ligero sobre las que se colocarán las células, se pueden sujetar en el interior del ala, por ejemplo, a las caras laterales de las costillas. De conformidad con lo anterior con la disposición según la invención hace posible un modo de vuelo para aficionados al vuelo deportivo, que es respetuoso con el medio ambiente, al utilizar un generador de energía renovable, como es la energía solar. También, se beneficiarán de vuelos más prolongados pues, si disponen del número de células optimizado según las condiciones de peso y orientación de las mismas y las necesidades de alimentación de las baterías y grupo motor, la aeronave podrá ser propulsada mientras luzca el sol. Con estas aeronaves, surge un nuevo incentivo en el arte de volar pues, por ejemplo, los motoveleros, no sólo perseguirán las térmicas o corrientes de ladera; a partir de ahora, también buscarán la mejor exposición posible al sol de sus células solares. Al ser utilizable las células solares sin modificaciones especiales en su fabricación se evita el proceso de enmarcado propio de la obra civil, su instalación en aviones ya fabricados es muy sencilla, siendo tan solo necesario variar partes de su carcasa o entelado exterior por otras de material transparente y,SUBSTITUTE SHEET RULE 26 to the solar radiation and its reflections, this surface, serves as protection to the cells of the inclemencies of the weather, humidity, friction of the air, etc. Therefore, the cells can be arranged in flat plates, without the need for glass or protective frames, and without special elasticity characteristics. The plates of light material on which the cells will be placed, can be attached inside the wing, for example, to the lateral faces of the ribs. In accordance with the above, the arrangement according to the invention makes possible a flight mode for sports flight enthusiasts, which is environmentally friendly, by using a renewable energy generator, such as solar energy. Also, they will benefit from longer flights because, if they have the number of cells optimized according to their weight and orientation conditions and the power needs of the batteries and motor group, the aircraft can be propelled while the sun shines. With these aircraft, a new incentive emerges in the art of flying because, for example, motorboats will not only chase the thermal or currents of the hillside; From now on, they will also look for the best possible sun exposure from their solar cells. Since solar cells can be used without special modifications in their manufacture, the process of framing of the civil works is avoided, its installation in already manufactured airplanes is very simple, being only necessary to vary parts of its housing or outer shell by others of material transparent and,
