Protect the aircraft.Give your mission a second chance.

RESBAG Systems develops lightweight airbag technology for UAVs equipped with emergency parachute recovery systems. By reducing touchdown loads and impact dynamics, the system helps protect airframes, sensors and valuable mission payloads.

Its impact-mitigation function can also support recovery-system safety objectives and M2 ground-risk mitigation compliance efforts under the EASA MoC to Light-UAS.2512 for the medium level of robustness.

MULTI-PLATFORM DEVELOPMENT

One principle. Different platforms.

The same protection principle can be adapted to fundamentally different aircraft geometries, mass distributions and payload arrangements — from compact UAVs to significantly larger aircraft.

TESTING & VALIDATION

From model to physical validation.

RESBAG combines analytical prediction with instrumented physical testing to achieve defined impact-performance targets.

MODEL & DESIGN

Predict before we build.

Geometry, pressure and venting are designed for defined impact conditions and target load levels.

DEPLOYMENT TESTING

Verify the complete sequence.

Physical testing confirms reliable deployment and a stable protective geometry before touchdown.

IMPACT VALIDATION

Measure the real response.

Instrumented testing validates predicted deceleration, deformation and energy-absorption behaviour.

VALIDATED ENGINEERING MODEL

Designed for predictable performance.

Physical testing closely matches the analytical prediction, allowing RESBAG configurations to be tuned toward defined target load levels rather than developed by trial and error.

Validated at meaningful scale

Physical testing confirmed the predicted response of the analytical model for a large multi-chamber configuration.

TECHNOLOGY

Protection activated for the final phase of recovery.

RESBAG complements the emergency parachute. The parachute controls the descent; the airbag manages the remaining touchdown energy and reduces the loads transmitted into the aircraft and payload.

01

Parachute activation

RESBAG interfaces with the emergency recovery system and starts the landing-protection sequence automatically.

02

Rapid deployment

The compactly stored airbag deploys and reaches its operating condition before touchdown.

03

Controlled energy absorption

The multi-chamber structure and calibrated venting extend the deceleration event and reduce peak loads.

APPLICATIONS

Built for aircraft where landing damage matters.

PLATFORM INTEGRATION

Designed around the aircraft, recovery system and payload.

RESBAG is developed as a platform-specific protection system. Airbag geometry, installation, activation interface and impact characteristics can be adapted to the aircraft configuration and the components that need to be protected.
