Abstract

Dans un nombre croissant de pays, la législation impose aux opérateurs de drone d'équiper le drone utiliser d'un parachute assurant un retour à terre avec une énergie définie. Le présent dispositif assure une éjection rapide et sécurisée d'un parachute selon le principe suivant : Un piston d'éjection (2) est comprimé dans un container (1) dans lequel les trouve le parachute. La compression préalable à l'éjection est assurée par un ressort (3). Le maintien de la compression est assurée par une suspente de Kevlar (4) tendue entre une goupille solidaire de la base et une goupille solidaire du piston. L'éjection du parachute est déclenchée par le sectionnement de la suspente par un cutter pyrotechnique (5). Le cutter pyrotechnique, de consommation très faible, peut être relié à un dispositif radiocommandé ou sur une carte analysant les conditions de vol.In an increasing number of countries, legislation requires drone operators to equip the drone with a parachute that returns to shore with defined energy. The present device ensures a quick and secure ejection of a parachute according to the following principle: An ejection piston (2) is compressed in a container (1) in which the parachute finds them. The compression prior to ejection is provided by a spring (3). The compression is maintained by a Kevlar hanger (4) stretched between a pin secured to the base and a pin secured to the piston. The ejection of the parachute is triggered by the cutting of the hanger by a pyrotechnic knife (5). The pyrotechnic cutter, very low consumption, can be connected to a radio-controlled device or on a map analyzing flight conditions.

Ejection de parachute pour drone par cutter pyrotechniqueEjection of parachute for drone by pyrotechnic cutter

La présente revendication concerne un dispositif d’éjection de parachute de sécurité pour un drone.The present claim relates to a safety parachute ejection device for a drone.

Dans un nombre croissant de pays, la législation impose aux opérateurs de drone d’équiper le drone utiliser d’un parachute assurant un retour à terre avec une énergie définie.In an increasing number of countries, legislation requires drone operators to equip the drone with a parachute that returns to shore with defined energy.

Le présent dispositif assure une éjection rapide et sécurisée d’un parachute selon le principe suivant :The present device ensures a quick and secure ejection of a parachute according to the following principle:

Un piston d’éjection (2) est comprimé dans un container (1) dans lequel les trouve le parachute. La compression préalable à l’éjection est assurée par un ressort (3). Le maintien de la compression est assurée par une suspente de Kevlar (4) tendue entre une goupille solidaire de la base et une goupille solidaire du piston. L’éjection du parachute est déclenchée par le sectionnement de la suspente par un cutter pyrotechnique (5). Le cutter pyrotechnique, de consommation très faible, peut être relié à un dispositif radiocommandé ou sur une carte analysant les conditions de vol.An ejection piston (2) is compressed into a container (1) in which the parachute is located. The compression prior to ejection is provided by a spring (3). The compression is maintained by a Kevlar hanger (4) stretched between a pin secured to the base and a pin secured to the piston. The ejection of the parachute is triggered by the cutting of the hanger by a pyrotechnic knife (5). The pyrotechnic cutter, very low consumption, can be connected to a radio-controlled device or on a map analyzing flight conditions.

Des évents assurent la bonne compensation de dépression et l’éjection éventuelle de gaz. Ni le drone, ni le parachute ne sont en contact avec le dispositif pyrotechnique.Vents provide good vacuum compensation and possible gas ejection. Neither the drone nor the parachute are in contact with the pyrotechnic device.

Les avantages de ce système : - son poids réduit ; - la dissociation entre la force d’éjection et la puissance requise pour le déclenchement ; - sa fiabilité, les cutter-pyrotechnique étant utilisés en parachutisme ; - sa modularité (parachute plié, pod).The advantages of this system: - its reduced weight; - dissociation between the ejection force and the power required for triggering; - its reliability, the cutter-pyrotechnic being used in skydiving; - its modularity (folded parachute, pod).

Le présent schéma de principe ne détaille pas les solutions de liaisons entre les éléments (câble-goupille par exemple (6)), solutions relevant de solutions techniques courantes.The present schematic diagram does not detail the connection solutions between the elements (cable-pin for example (6)), solutions under current technical solutions.
