Description

An Electric Power Generation System By Means of the Effects of

Wind and Airplane at Airports

Technical Eield

This invention is related to a system that ensures power generation as the result of using the turbulence, ground effect and exhaust gas created by the airplanes during their take-off and landing at the airport, by means of wind turbines to be established at a safe distance.

Prior Art

High security areas such as the runway, apron, taxi ways etc, in which all air and road vehicles move according to certain rules and which are arranged according to the air vehicles, are called air space. In the known status of the technique, there is not any power generation method in the area called airspace at the airports. The reason of this is to give particular importance to the safety of the airplanes primarily at these spaces and the necessity of supplying continuous and uninterrupted energy needs of the passenger and technical units rather than energy saving. Thus, no power generation need has arisen within the airspace of the airports. Although the potential energy in this area can be convertible within the aviation rules, it has been wasted for a long time.

Existing systems of the airports are systems for obtaining all energy of the airport uninterruptedly from 3 different sources. Energy needs of the terminal technical blocks and navigation systems of the airports are outsourced.

In existing system, energy costs of bother the terminal and technical blocks are high and it is necessary to supply this energy need from outside continuously. Meeting energy needs of the navigation systems and terminal building outsourced and uninterruptedly is very important for this industry, however; thanks to this invention, energy needs of the buildings such as technical blocks, workshops etc, can be covered from this energy potential of the airports and energy costs can be reduced.

Purpose of the Invention

Purpose of the invention is; to reduce energy costs of the airports and to ensure more effective utilization of the resources by ensuring recycling of the fuel expenditures, which is the main factor in flight costs of the airplanes.

Another purpose of the invention is to increase the resources of investment to be made by the airport operator by means of the profit to be brought with this energy saving and returning the energy potential wasted to economic value.

Another purpose of the invention is to keep the airport active by supplying alternative energy in case of situations such as interruption in air traffic, shutting down of radar and flight systems resulting from possible blackouts in case of any national blackout, natural disaster and warfare.

In order to achieve the purposes mentioned, power generation is ensured as the result of using the turbulence, ground effect and exhaust gas created by the airplanes during their take-off and landing at the airport, by means of wind turbines to be established at a safe distance.

Detailed Description of the invention Since airports are built at areas exposed to wind regularly, generating power with wind turbines at these areas carries an economical value.

Main element that feeds the system is the thrust power generated at exhaust outlets of the jet engines of the planes while they are moving on the ground. The system has been designed not only for capturing this power, but also for running the wind turbines by benefiting from the aerodynamics and laws of physics during the landing and taking off of the planes.

One of the potential energy provides that will considered in the invention is the wing tip turbulence taking place as the result of the motion on the wing tips. This air movement taking place on the wing tips of the airplane is effective throughout the flight, landing and take-off. Power generation is performed by means of the side wind turbines (6) positioned at runway ( 1 ) sides by exploiting the turbulence generated by the wings of the plane during the period from the start of movement by the plane at the runway heading ( 5) to the time to take off.

Another energy provider of the system is the ground effect taking place during the landing of the planes. Ground effect emerges at the moment that the planes approach to the ground while they are landing. This effect takes places as the outward movement of the air under the wings of the plane, towards the sides perpendicular to the plane's body.

In order to use these two above stated effects in power generation, small side wind turbines (6), with the distance and heights confirming to the aviation rules, are placed in certain intervals on both sides (right and left side of the runway) of the runway ( 1 ). However, since these turbines (6) are inside the airspace, wind catchers must have been designed according to the technical specifications applied in the air spaces, in that; heights of the side (6) and corner (7) turbines of the runway (1 ) are limited to 1 meter when compared to the ground. Thus, both the side (6) and corner (7) turbines are designed specially. Layout of the side turbines (6) mentioned above are explained in Figure-4.

Side turbines (6) located along the runway (1) are placed along the side of the runway (1 ) according to certain rules.

Third effect in the system is the exhaust effect of the jet engine. Airplanes have to discharge the exhaust gas after they start their engines. Reaching high speeds by the airplanes happens as the result of this powerful effect. This effect exists while the plane is yet on the ground and throughout its trip to the runway (1 ). Thanks to the exhaust effects arising from this ground movement, energy is obtained.

As seen from Figure-4 and Figure-8, in order to catch the exhaust effects during right and left turn movements of the airplanes on the taxiways (2), corner wind turbines (7) at a certain distance and height are placed on the right and left side of the taxi way (2). Jet engine radius and forces are explained in Figure-3. Corner wind turbines (7) are located with 45 degree angle to the runway ( 1 ). This angle can be between 30 and 75 degrees.

Furthermore, power generation is ensured by exploiting exhaust effects of the plane taking off, by placing large scale wind turbines (8) at runway headings (5).

Large scale wind turbines (8) with the locations stated in Figure-4 and

Figure-5. are vertical axis turbines and their propeller (wind) (9) diameter is maximum 15 meters. At least 1 large turbine (8) is placed at the runway headings (5) and there is a gap of preferably minimum 15 meters between this and second large turbine (8) to be placed. The field, where large turbines (8) are positioned, is called the "escaping field) located at the runway headings (5). There is a distance of minimum 15 meters between two turbines meeting the maximum plane axis clearance safely. Heights of the large turbines (8) are limited to 1 meter when compared to the ground of the runway ( 1 ). Large turbines (8) to be driven by the exhaust gas effects are vertical axis turbines and they are placed in a special ferroconcrete structure. Heights of the large turbines (8) are limited to 1 meter when compared to the ground of the runway ( 1 ). Side (6) and corner (7) turbines are fixed but large turbines (8) have the ability to move upwards and downwards.

Turbine room ( 1 1 ) is located just under the large turbines (8). Among the large turbines (8) to be placed at the runway headings (5), those located in the opposite of the take-off direction of the planes, ascend from the ground and capture exhaust gas of the plane while it's taking off and large turbines (8) at other end (runway heading) descend to the turbine room( l l ) at closed state. Upon changing of the wind direction and/or take off directions of the planes, closed large turbine (8) will ascend and start running while the opposite large turbine (8) will descend to the room. These large turbines (8) located at the runways headings (5) are protected inside of a ferroconcrete structure that has the standards for carrying airplane loads. Furthermore propellers (9) of the large turbines (8) are located in a separate chamber. This chamber is located in a system that can move upwards and downwards and is available for opening and closing.

Power generation by each turbine in the system separately and transferring such power to the mains by means of a transformer, the support provided by both the side (6) and corner (7) turbines by generating power in order to keep the large turbines (8) moving, ensure conversion of the potential that has never been used before, to an economical value. With this system, energy is supplied to every point except the navigation systems. The more the number of airplanes landing and taking off the airport is, the higher wiii the amount of energy be increased. Even if there is no wind flow at the airport, energy generation can be performed just thanks to the effects caused by the planes. Thanks to the invention, contribution of the jet fuel spent by fossil fuel driven airplanes to the energy generation is aimed since it is anticipated that this value will increase depending on the number of planes at an airport with the average wind regime of about 7 knots.
