DRS-M300 parachute recovery product

The DRS-M300 is a parachute recovery product from Drone Rescue Systems, sold on the maker's site as the DRS-M300/M350, and designed as a recovery parachute system for multirotor drones, in particular the DJI M300 and M350 class. It is meant to slow a falling aircraft to a descent speed and impact energy that protect people and property on the ground when a flight fails.

The unit is compact. Its height is 165 mm and its diameter is 100 mm, and the complete system weighs about 460 g. This mass is the figure that matters for payload and endurance planning, because it is added to the take-off weight of the carrier aircraft. The design is reusable, so the system is not discarded after a deployment event.

The performance data are given for two aircraft masses. At 6.5 kg the descent velocity is 3.3 m/s and the impact energy is 35 J, and at 9.7 kg the descent velocity is 3.6 m/s and the impact energy is 65 J. Impact energy is the quantity that regulators and risk assessments compare against injury thresholds, so these figures let an operator check a mission against the limits of its safety case. The maker states that the parachute deploys within 25 m, which describes how much height is needed for the canopy to open and take effect.

For integration, the system connects to the aircraft through the O-SDK and P-SDK interfaces. Optional functions are geofencing and a trigger from the remote control, so deployment can be started by a flight-termination boundary or by the pilot. Integration support for OEMs and integrators is offered by the maker, and the page lists the DRS-M300/M350 within its range of ready-to-fly parachute sets.

On certification, the maker states that the system is certified to ASTM F3322-22 and to MOC-2512, and that it is eligible for testing according to EASA MOC-2511. These references matter to operators preparing operational authorisations for flights over people or in specific-category operations in Europe, where a parachute with recognised test evidence can reduce the risk class of the operation.

Typical applications are professional inspection, mapping, public-safety and survey missions flown with heavy-payload multicopters, where a recovery system is required by the operating authorisation or by the operator's own risk policy.
