    The invention is an energy recuperator that recovers the kinetic energy transmitted to the air by a moving vehicle or mechanism when it acquires speed. This air is collected by a collection bell (4) that reduces the section, causing the air to increase its speed and its kinetic energy. The air passes through a turbine (3) where it rotates the blades, transforming the energy of the air into mechanical energy transmitted to the shaft (this turbine can be centrifugal, axial or mixed, with one or more steps). The mechanical energy is transferred to the shaft of an alternator (1), through a transmission that can be rigid or flexible, where it is converted into alternating electric power. Through the primary electric circuit (2) arrives at the rectifier (5), where it is modified to continuous electric current and through the secondary electric circuit (6), we drive it to the batteries (7) to recharge them, while the vehicle is in motion.

    5
    SECTOR OF THE TECHNIQUE
    The present invention can be included in various sectors of manufacture of vehicles dedicated to the transport of people and goods, by road, rail and
    10 aerial:
     Automobile sector  Passenger transport sector by road  Freight transport sector by road  Railway locomotive sector
    15  Aviation sector
    The main object of this invention is the design of a device consisting of a kinetic energy recuperator that a moving vehicle transmits to the surrounding air. When it reaches sufficient speed, so as to be able to recover said energy, a part of the air is introduced into a turbine that transforms it into mechanical energy. Said energy is transferred to the axis of an alternator or generator of electrical energy and derived to a rectifier to transform it into continuous electrical energy and to be able to recharge the batteries of the electric vehicles while they are in motion, which allows to exponentially increase their autonomy, reduce costs of transport and also effectively combat pollution of the
    25 environment.
    BACKGROUND OF THE INVENTION
    Today, we have a global problem with global pollution of the planet and in particular in the big cities where sometimes they are exceeded
    30 the advisable values to maintain an acceptable air quality for its inhabitants. Overlapped with this problem we have a solution: electric or hybrid vehicles, but they have a real unsolved problem: autonomy in their medium and long journeys due to the low duration of their batteries.

    With the invention that we present, the problem is solved and it gives viability to this type of vehicles, because we exponentially increase their autonomy and reduce transport costs in a very radical way.
    Technically the invention is based on fluid mechanics, specifically in the application of Bernouilli's Theorem, and as a fluid, in our case, the air that a vehicle displaces when moving through it.
    EXPLANATION OF THE INVENTION
    The energy recuperator object of this invention is based as we have previously explained in fluid mechanics and consists in passing the air, which moves a moving vehicle, through a pickup hood, where the kinetic energy is increased by increasing the passing speed also increases the dynamic pressure and the static pressure, as the output section decreases. Then we pass the air through a turbine of special characteristics, always depending on the power to be recovered and the type of vehicle where it will be installed, through the blades we transmit the kinetic energy of the air to the axis of the turbine as mechanical energy, which at in turn it will be coupled to the axis of an alternator or electric generator that will be responsible for transforming mechanical energy into electrical energy. Then we pass this alternating current electrical energy through a rectifier and transform it into continuous electrical energy, recharging the batteries in this way, while the vehicle is in motion.
    The energy recuperator is fixed to the structure of the vehicle with flexible supports to prevent the transmission of noise and vibration from one to another, calculated to withstand the stresses caused by the angular velocities of its components and weight. The recommendations of ISO 10816 regarding maximum angular speeds have been taken into account in the design of the invention.
    ENERGY RECOVERY COMPONENTS
    The components of the invention are described below:
     AIR OR TOWER CAPTION HOOD (4)
    It is formed by a hollow body with an entrance for the air of greater section than the exit, of conical or pyramidal trunk of circular, ovoid, square or rectangular section, depending on the application. The dimensions will be calculated for each specific case and will depend on the vehicle design where it will be installed and the amount of energy to recover. The function of this bell is the admission of the


    as much air as possible, always depending on the speed of the vehicle, the increase in the speed of the air passing through it and the discharge in the next component that is the turbine.
     ENERGY RECOVERY TURBINE (3)
    The function of the turbine in the invention is to transform the kinetic energy with which the air arrives in the form of dynamic and static pressure (in application of one of Bernouilli's equations) and transform it into mechanical energy, according to the expression :
    P = d * g * Q * HT (W)
    Being:
    10 P The total mechanical power recovered in watts (W).
    D Air density at average conditions of 20 ° C.
    g The acceleration of gravity.
    Q The air flow through the turbine.
    HT The total pressure (dynamic pressure + static pressure) at the inlet of the turbine minus the total pressure (dynamic pressure + static pressure) at the outlet of the turbine.
    This turbine may be centrifugal, axial or mixed, with one or several steps or stages, always depending on the application where it is to be installed and the power to be recovered. The section of this turbine may be circular, square, rectangular or
    20 any other way, and always depending on the calculations made for each case. The turbine calculation is carried out by the adiabatic study of the turbine and the sizing will be carried out depending on the application and the electrical power to be recovered.

     PROTECTION ELEMENTS
    The energy recuperator has an electronic protection system enabled in the control unit of the vehicle, electromechanically operated and consisting of the following elements:
    The coupling between the turbine shaft and the alternator shaft will be designed according to the application and the power to be recovered by the invention, but the union will always have an electrical disconnection system to protect the alternator.
    The electrical system is equipped with two cutting and protection elements, one in the primary alternating current system and the other in the secondary direct current system, operated from the vehicle control unit and used to protect the system and prevent overload. of the batteries. For this, the information to reach the control unit will be processed, reflecting the information on the control panel for the driver's knowledge. It will act according to the information obtained by a series of probes located inside the energy recuperator and distributed according to the following relationship:
    a) Total air pressure probe located at the turbine inlet.b) Dynamic pressure probe located at the outlet of the turbine.c) Alternator and rectifier temperature probes.d) Probe for reading the intensity in the alternating current circuit.e) Probe for reading the intensity in the continuous current circuit.f) Battery charge level probes (one per battery).
    The first two probes will give us information about the recovered mechanical energy and the dirt state of the turbine, indicating the time to clean it. The next three will give us the information of the electrical performance of the recuperator and will make the protection system act when necessary. And the last probe will give us the information of the state of the battery charge, acting on the charge protection system when it reaches its limit.
    POWER RECUERATOR OPERATION
    The operation of the invention is described below: the vehicle, when set in motion, provides the air with a reaction in the opposite direction to travel; This air in conventional vehicles is used for cooling the internal combustion engine. That air, as the vehicle acquires speed, provides an energy that from a specific point, with our invention we can recover.
    A certain air flow enters the hood or nozzle, located in


    the front part of the vehicle, circulates towards the interior of the vehicle where, when the passage section decreases, this air flow increases the speed until reaching the critical point, which is the entrance into the turbine. At that point of maximum speed (which is the point of greatest kinetic energy of the system) we pass the air to the turbine, which will cause a pushing force on the blades, which in turn will turn the turbine at a speed angular depending on the speed of the vehicle and, in this way, the turbine transforms the energy of the air into mechanical energy by transmitting it to its axis. The turbine shaft in turn transmits the mechanical energy to the alternator shaft and it converts it into alternating current electrical energy. Through the circuit
    10 primary electric we get to the rectifier this alternating current, where it is transformed into direct current and through the secondary electrical circuit is transferred for the charging of the vehicle's batteries. The air discharged by the turbine can also be used to cool the electric motors and vehicle power batteries.
    The recharging power of the batteries will depend on the corresponding design of the recovery capacity of the invention and the speed at which the moving vehicle circulates.
