Description

MULTI PLI CATEUR STATI QUE A PLUSIEURS ETAGE S DE LA VITESSE D ' UN MULTI FOLDER STATI THAT ON SEVERAL STAGES OF THE SPEED OF A
FLUIDE .  FLUID.
Cette invention permet d'augmenter la vitesse d'un fluide sans utiliser de pièces mécaniques mobiles, ce qui est avantageux dans de nombreuses applications, notamment quand la vitesse du fluide est limitée, ou son volume important.  This invention makes it possible to increase the speed of a fluid without using moving mechanical parts, which is advantageous in many applications, in particular when the speed of the fluid is limited, or its large volume.
On sait. qu'un fluide animé d'une vitesse V et heurtant un obstacle AB de C supérieur à un voit sa vitesse augmenter à partir de la dernière arête percutée (A-Fig 1), selon la formule : Vitesse résultante ou de fuite =Vitesse amont x We know. that a fluid animated with a speed V and striking an obstacle AB of C greater than one sees its speed increasing from the last edge struck (A-Fig 1), according to the formula: Resulting or leakage speed = Upstream speed x
Vf = VaxV f = Vax
L'augmentation de vitesse la plus grande est obtenue avec un obstacle semi-circulaire creux(Fig 2) de C = 2,3,1e plus grand connu,pour une forme géométrique simple.  The greatest speed increase is obtained with a hollow semi-circular obstacle (Fig 2) of C = 2,3,1e largest known, for a simple geometric shape.
Si cette opération pouvait se répéter, comme dans les amplificateurs électroniques, on améliorerait fortement la puissance des appareils utilisant l'énergie des fluides, ou leur précision.  If this operation could be repeated, as in electronic amplifiers, we would greatly improve the power of devices using the energy of fluids, or their precision.
Ce profil en travers du courant de fluide peut être consi- déré comme un amplificateur de vitesse de coefficient K= This cross-section of the fluid current can be considered as a speed amplifier with coefficient K =
au moins pour la zône CE(Fig 2), qui borde le sillage en dépression (abcde-Fig 2). On peut placer un autre obstacle(FG- Fig 3)en travers de la veine accélérée ( H1 H2-Fig 3) de manie re à obtenir une nouvelle accélération du fluide quittant at least for the CE zone (Fig 2), which borders the wake in depression (abcde-Fig 2). Another obstacle can be placed (FG- Fig 3) across the accelerated vein (H 1 H 2 -Fig 3) so as to obtain a new acceleration of the fluid leaving
FG Fig 3).Pour cela, il faut que l'obstacle FG intercepte la veine accélérée H1H2(Fig 3) sur une largeur L2 inférieure à celle de départ (L1), et relier FG à CD par une paroi CF (Fig3) pour que le phénomène d'accélération se reproduise, la largeur de la veine accélérée une seconde fois diminuant propor- tionnellement à sa vitesse. FG Fig 3) .For this, the obstacle FG must intercept the accelerated vein H 1 H 2 (Fig 3) over a width L 2 less than that of departure (L 1 ), and connect FG to CD by a wall CF (Fig3) so that the acceleration phenomenon occurs again, the width of the vein accelerated a second time decreasing proportionally to its speed.
L'augmentation de la vitesse du fluide provoque derrière  The increase in fluid speed causes behind

répondant aux conditions de position et dimensions précédentes (lignes 22 à 26).  meeting the conditions of position and previous dimensions (lines 22 to 26).
Il y a un moment où l'augmentation de la vitesse du fluide est telle que l'épaisseur (e-Fig 3) de la veine devient in.. .. insuffisante, cette dernière se transformant en tourbillons inefficaces. There is a moment when the increase in the speed of the fluid is such that the thickness (e-Fig 3) of the vein becomes in .. .. insufficient, the latter transforming into ineffective vortices.
APPLICATIONS. 1) La multiplication de la vitesse du fluide augmente fortement la puissance d'une machine (T)utilisatrice de ce fluide, pour une même dimension(Fig 4 ) , comme une turbine aéraulique par exemple.  APPLICATIONS. 1) The multiplication of the fluid speed greatly increases the power of a machine (T) using this fluid, for the same dimension (Fig 4), such as an aeraulic turbine for example.
2) Si cet obstacle multiplicateur est développé en couronne autour d'une turbine (T) par exemple ( coupe de la Fig 5), la vitesse du fluide accéléré donnera encore plus de puissance. 3) Si deux autres obstacles, M' et M" (Fig 5), sont placés des deux côtés de l'obstacle principal, DC , en couronne également, la dépression Dp derrière l'ensemble augmentera en core plus, donc aussi la puissance développée par la turbine(T) la vitesse, donc l'impact du vent en W(Fig 5)>étant plus grande. 4) Le fonctionnement des déprimomètres et mesureurs de fluide est fortement amélioré grâce à la dépression plus grande, qui augmente la sensibilité des appareils (Fig 6), et permet de les rendre plus robustes. 2) If this multiplying obstacle is developed in a ring around a turbine (T) for example (section in Fig 5), the speed of the accelerated fluid will give even more power. 3) If two other obstacles, M 'and M "(Fig 5), are placed on both sides of the main obstacle, DC, also in the crown, the depression D p behind the assembly will increase in even more, therefore also the power developed by the turbine (T) the speed, therefore the impact of the wind in W (Fig 5)> being greater. 4) The functioning of the pressure gauges and fluid meters is greatly improved thanks to the greater depression, which increases the sensitivity of the devices (Fig 6), and makes them more robust.
5) Transmission pneumatique et hydrauliqueL'augmentation de la vitesse des fluides en fin de parcours évite ou compense partiellement les pertes de charge dans les canalisations, tant pour les mesures que pour les télécommandes et le transfert depuissance. 5) Pneumatic and hydraulic transmission The increase in the speed of the fluids at the end of the journey avoids or partially compensates for the pressure drops in the pipes, both for measurements and for remote controls and power transfer.
6) Pistolets de décapage ou de forage dans le travail des surfaces, avec des fluides purs ou chargés, dont l'impact est renforcé. 6) Pickling or drilling guns in surface work, with pure or charged fluids, the impact of which is reinforced.
7)TETES de forage minier et sous-terrains de toutes natures. EXEMPLE D'APPLICATION: Pistolet de décapage à air comprimé. Un tube de section rectangulaire P (Fig 7) est fermé à son extrémité par une paroi métallique épaisse profilée selon, le croquis DCFG, répondant aux conditions des lignes 22 à 26, page 1.

APPLICATION EXAMPLE: Compressed air blasting gun. A tube of rectangular section P (Fig 7) is closed at its end by a thick metal wall profiled according to the sketch DCFG, meeting the conditions of lines 22 to 26, page 1.
