    FIELD OF THE INVENTION
    The present invention is a blue light bridge, in which a plurality of turbulence generators are installed, which improve the aerodynamic behavior of the vehicle and reduce the dynamic effort in attaching the blue light bridge on the vehicle.
    Particularly frequent application undergoes the invention in the field of automotive accessories industry.
    TECHNICAL PROBLEM AND BACKGROUND OF THE INVENTION
    The inclusion of turbulence generators is well known in the art. In aviation technology, the incorporation of turbulence generators is an activity that is constantly evolving to improve the stability of aircraft. Also, the incorporation of such generators in single seat racing cars of Formula 1 is one of the main fields of application for improving the aerodynamic characteristics of the vehicles.
    At the application level, however, the aerodynamic design has hitherto been limited practically only to a corresponding shaping of the surfaces or the attachment of spoilers. The attachment of turbulence generators has not been successful and has hitherto been limited almost exclusively to situations in which high speeds or a considerable improvement in aerodynamic properties had to be achieved.
    In the sense of a brief conceptual excursion into the field of aerodynamics, it should first be pointed out that the air resistance depends on how fast the vehicle is driven and on which type of surface the air impinges. If air impacts abruptly on a surface, depending on the conditions of impact, different fine air layers are formed due to the differences in speed created by the friction, each of which has a different speed per se - the closer they are to the surface, the lower the speed , Depending on the shape of the surface and its air resistance, there may be layers of air that are stopped or even forced back, preventing the air from circulating properly and disrupting and altering its direction of flow - ultimately leading to the formation of turbulence.
    To understand this effect, it must be considered that those layers which form the aerodynamic flux, in turn, also consist of individual particles.
    From an aerodynamic point of view, it is desirable that this air flow be as little as possible divided into individual layers so that the particles of each layer flow as ordered as possible, thereby preventing them from interfering with each other, causing aerodynamic drag in the form of turbulence causes.
    The entirety of the particles which come into contact with the surface of the tread is called "boundary layer". This layer loses speed as a result of the friction present and tends to assume the speed of the surface with which it comes in contact. This decrease in speed now causes the speed of the subsequent layer to decrease as well - this continues from layer to layer until this effect is lost.
    In just such cases turbulence generators are used to change the air behavior, whereby it is achieved that the air no longer flows in directions that seem counter productive with regard to the incoming air. On paper, the formation of vortices is counterproductive because it involves converting a layered flow into turbulence as well as a set of layers of ordered particles into a chaos that causes turbulence and air resistance.
    The flow generator produces small, controlled vortices that minimize damage by creating small turbulences that retard greater turbulence that causes separation of the boundary layer. The aim is to degrade the quality of the aerodynamic flow in order to preserve its effect for a longer time.
    Turbulence generators are signs or tails, which ensure that the air flowing through the area in question escapes at the moment of contact in the form of a vortex or air vortex.
    The vortex acts as the moment influencing the aerodynamics, which produces various effects: the most common is the diversion of air into certain areas, the successful elimination or control of turbulence, the prevention of breakage of the air boundary layer, the aerodynamic sealing certain vehicle zones or the reduction of air resistance of certain collision components.
    The problem that concerns us in the present invention is caused by the fact that a blue light bridge is mounted on the vehicle roof. This additional component degrades the vehicle's aerodynamic properties by creating a narrow, long space between the two components that results in breakage of the boundary layer and the formation of turbulence that adversely affects the aerodynamic characteristics of the vehicle.
    The solution proposed by the present invention consists mainly in the inclusion of a number of turbulence generators, which prevent the formation of said turbulence, improve the adhesion of the light bridge on the vehicle roof and the aerodynamic properties of the vehicle.
    DESCRIPTION OF THE INVENTION
    The present disclosure is a blue light bridge to be mounted on the roof of a vehicle. In the blue light bridge, there are several turbulence generators located on the surface closest to the vehicle roof, where an opening is created in which aerodynamic turbulence occurs. The turbulence generators are equidistant from one another in a row and facing the edge of the blue light bridge which the air impinges on.

    DESCRIPTION OF A PREFERRED EMBODIMENT OF THE INVENTION
    The present invention is a on a vehicle roof (2) located blue light bridge (1), in which several turbulence generators (3) were installed.
    As can be seen in Figures 1 and 2, attachment of the blue light bridge (1) on the vehicle roof (2) provides an open area within the connection in which there is a tendency to form turbulence. This turbulence zone has a negative effect on the aerodynamic properties of the vehicle. Moreover, the turbulences that arise between the blue-light bridge (1) and the vehicle roof (2) also produce vertically acting forces that can even cause the fastening to become loose.
    2, the inventive blue light bridge (1) includes a number of turbulence generators (3) in the lower, the vehicle roof (2) closest to the surface, where there is also the turbulence zone. The turbulence generators (3) convert said turbulence into a stratified flow which extends over the entire surface of the blue light bridge (1) until the air escapes, thereby avoiding the aerodynamic and fastening problems mentioned.
    The turbulence generators (3) are mounted so as to cover the entry of air between the blue light bridge (1) and the vehicle roof (2).
    In Fig. 3, the configuration of the various turbulence generators (3) is shown pictorially. The number of turbulence generators (3) to be installed in the blue-light bridge (1) will depend on the speed and conditions of use of the particular vehicle, the geometry of the turbulence generators (3) and, in particular, the design of the surface of the connecting elements in the turbulence zone. For use in city traffic at controlled speeds between 50 and 120 km / h, the turbulence generators (3) shown in the figure are arranged at a distance of 100 +/- 20 mm from each other. The lower surface of the blue light bridge (1) may be as flat as possible; the only interferences arise here on the reinforcing elements for the fastening elements on the vehicle roof (2).
    It should be noted that the present invention need not be limited to the embodiment described here. Qualified persons can also develop other configurations from the description given here. Accordingly, the scope of the present invention is defined by the claims set forth below.
