Tuotteen tiedot
Mallinumero: DA-Zephyr-M300-Single
Paino: 1 kg

The lightest parachute system on the market: only 450 g !

The basic parachute kit includes an ultra-fast CO2 - canopy ejection system as well as a dedicated autonomous remote control with 30 hours of autonomy (to be attached to the Smart Controller).

The parachute is also available in a DGAC S2 S3 approved kit with an internal FTS (to be installed in the workshop) or external (to be inserted between the batteries and the drone). Each version of FTS includes an audible alarm and support to power and charge the parachute when the drone is on.

The lightest engine shut-off parachute system in the world!

The parachute kit + internal FTS is the lightest solution available on the market, with a total weight of only 455g. It keeps the most important cargo capacity for the DJI M300 in S3 scenario: 1.25 kg of available payload! In scenario S2, the maximum possible weight increases to 2.25 kg.

Note that at equivalent payload, the flight time is longer with the Zéphyr parachute than with another parachute system.

The internal FTS is installed in the workshop inside the drone by us. The operation is reversible, it does not modify the drone and allows the DJI manufacturer's warranty to be retained. The sound alarm module is connected to the USB-C socket available under the drone.

The FTS can be used alone, without a parachute, in order to increase the available load and the flight time for scenario S2. The payload of the Matrice 300 in scenario S2 increases in this configuration to 2.7 kg!

Dronavia is proud to be the first manufacturer to provide MoC Light-UAS.2511.01 compliant systems, an essential compliance in the development of a Special Operations Risk Assessment (SORA). Dronavia will provide with each Zéphyr CC M300 FTS system sold, a MOC 2511 declaration of conformity. This document can be integrated into a SORA and is sufficient to meet the requirements of Part 9.

Ultra-fast system setup

Attached to the 4 upper threads of the drone, the parachute can be disassembled in less than a minute. An optional bracket is available on our shop to fix it under the drone when using the upper pod.

The kit with the external FTS can also be dismantled in a few seconds. FTS modules are simply inserted between the batteries and the drone. They directly include the audible alarm. Their weight is 160 g.

All the kit elements can be stored in the original flight case supplied by DJI with the drone.

The fastest, most reliable and efficient CO2 system

The Zéphyr parachute CO2 ejection system has been proven and used by a majority of French drone pilots for more than 5 years. Numerous successive tests and improvements have brought this system to levels of reliability never before achieved on a drone parachute.

The pressurized gas (60 bars!) Is released in a fraction of a second to propel the parachute canopy out of its container. The excess gas released (each cartridge contains several tens of liters) is used to accelerate the deployment of the canopies and minimize the loss of altitude when the parachute is triggered.

The system can be reset in a few seconds. The CO2 cartridge is the only consumable that needs to be changed on the system after deployment and a cartridge only costs a few dollars.

On the Zéphyr M300 single canopy parachute system, the CO2 ejection system allows the canopy to be expelled and opened in just 1.2 s, which corresponds to an altitude loss of 15 m from a initial fall speed of about 6 m / s.

The lightest, most stable and efficient drone parachute covers

The new PARA² fabrics used in Zéphyr parachute systems are the result of 3 years of development. Their innovative ultra-light design and unique design give PARA² fabrics superior efficiency and stability. On single canopy systems, the sink rate is reduced to a minimum relative to the canopy area. Used in pairs, PARA² fabrics do not interfere with each other and optimize the overall drop rate. Each Zephyr parachute is designed so that the canopy (s) keep the drone as flat as possible during its fall so as to minimize damage during impact.

On the Zéphyr M300 single-canopy parachute system, the fall speed for a mass of 8 kg is only 3.2 m / s, i.e. an impact energy of only 41 J, much lower than the maximum 69 J authorized in France.

A long-range encrypted communication system

The long-range communication system between the radio and the parachute is based on advanced technologies and LoRa modulation. Its range can reach several kilometers in optimal conditions and a long range option makes it possible to exceed 10 km.

The communication protocol is based on 869 MHz frequencies, free of authorization (433 and 915 MHz options possible). 128-bit encryption ensures data is not intercepted and the user is notified in the event of a communication disruption.

Convenient features for the user

  • The parachute, FTS and radio control modules are equipped with LEDs for status indication and advanced functions.
  • The LEDs indicate the remaining battery charge when switching on and off as well as the battery level during charging. In operation, they indicate the instantaneous state of the system: correct operation, loss of radio link, low battery level, etc.
  • Coupled with a FTS, the parachute turns on automatically when the drone is turned on. Without a signal and if you forget to switch off the parachute or the radio control, the modules switch off automatically after 10 minutes.
  • A time-stamped log system integrated on the parachute and the radio. It records the trigger actions performed by the user for diagnostic purposes.

Many options .. ahead of the regulations!

The options available with Zéphyr parachutes allow you to get a head start on French and European regulations.

On the remote control side, it is possible to add a second redundant trigger button. This second button avoids the possible untimely pressing of a single button and doubles the autonomy of the remote control. Safety caps protect the buttons against unwanted presses. A buzzer module is available on request. It generates an audible warning in the event of loss of connection with the parachute. A long range option allows the radio range to be extended to more than 10 km if necessary. It is also possible to associate several radio controls with a parachute, or several parachutes with a radio control.

A crash detection and automatic triggering module is available on request. This module will eventually be compatible with future European standards (class C5 for STS-01 scenarios).
