Abstract

Inertial winch for take off by gliders. The invention relates to a glider winch equipped with an inertial fly wheel making it possible to have available significant instantaneous power although the energy is supplied by a low-power motor. It is constituted by an inertial fly wheel 3 flanked by two transmissions 2 and 4 which are themselves linked to an engine 1 and a drum 5.

Description

1 1- DESCRIPTION
L'invention concerne le vol à voile et les planeurs.1 1- DESCRIPTION
The invention relates to gliding and gliders.

Les treuil s de vol à voile doivent fournir une puissance instantanée très élevée durant un temps très court. La technique existante qui consiste à entrainer directement le tambour d'enroulement du câble avec un moteur, par l'intermédiaire d'une transmission, nécessite un moteur d'une puissance disproportionnée par rapport à l'énergie totale mise en jeu lors d'une treuillées.  Gliding winches must provide very high instantaneous power for a very short time. The existing technique which consists in directly driving the cable winding drum with a motor, by means of a transmission, requires a motor of a disproportionate power compared to the total energy involved during a winches.

Deux inconvénients majeurs découlent de cette technique : d'une part un risque considérable pour le planeur en cas d'incidents sur le moteur, d'autre part, un moteur d'une puissance et d'un coût excessifs. Two major drawbacks arise from this technique: on the one hand a considerable risk for the glider in the event of incidents on the engine, on the other hand, an engine of excessive power and cost.

L'invention consiste à introduire un volant d'inertie dans la chaîne cinématique du treuil. Celui-ci permet de stocker l'énergie fournie en continu par le moteur, laquelle est cédée au tambour selon les séquences très brèves propres aux opérations de treuillage. The invention consists in introducing a flywheel in the kinematic chain of the winch. This makes it possible to store the energy supplied continuously by the motor, which is transferred to the drum according to the very brief sequences specific to winching operations.

Moteur et tambour sont alors disposés de part -et d'autre du volant d'inertie, chacun de ceux-ci étant reliés à ce dernier par une transmission adaptée. Motor and drum are then arranged on either side of the flywheel, each of these being connected to the latter by a suitable transmission.

I1 découle de l'invention à la fois la suppression des risques liés aux incidents de moteur ainsi qu'un abaissement considérable de la puissance requise pour le moteur. It follows from the invention both the elimination of the risks associated with engine incidents as well as a considerable reduction in the power required for the engine.

La figure N 1 représente la channe cinématique caractéristique des treuils existants. Figure N 1 represents the kinematic chain characteristic of existing winches.

La figure N 2 représente la chaîne cinématique caractéristique du treuil objet de l'invention,
La figure N 1 rassemble les 3 éléments principaux suivants : le moteur (1), la transmission ou accouplement (2), le tambour d'enroulement(3
'La figure N" 2 rassemble les 5 éléments principaux suivants : le moteur par entraine qui par (1) Ila transmission d'amont(2jevolant d'inertie 11a transmission d'aval (4), le ou les tambours (5).FIG. 2 represents the kinematic chain characteristic of the winch which is the subject of the invention,
Figure N 1 brings together the following 3 main elements: the motor (1), the transmission or coupling (2), the winding drum (3
'Figure N "2 brings together the following 5 main elements: the driven motor which by (1) Ila upstream transmission (2 flywheel inertia 11a downstream transmission (4), or the drums (5).

Le fonctionnement du treuil, objet de l'invention, se caractérise d'une part, par un processus de stockage continu de l'énergie fournie par le moteur, d'autre part, par un processus de déstockage syncopé sur la base d'un temps court et d'une puissance élevée disponible sur le tambour.The operation of the winch, object of the invention, is characterized on the one hand, by a process of continuous storage of the energy supplied by the motor, on the other hand, by a syncopated destocking process on the basis of a short time and high power available on the drum.

L'application industrielle de l'invention est liée à la construction en série de ce nouveau type de treuil à l'usage des adeptes du vol à voile.  The industrial application of the invention is linked to the series production of this new type of winch for the use of gliding enthusiasts.
