Drone airbags for UAV recovery

Airbags absorb impact energy and are most commonly used on unmanned platforms that land under a parachute without traditional landing gear.

What airbags are for

Airbags absorb energy when a UAV lands. Similar to automotive airbags, these military-grade inflatable energy absorption systems are designed to protect the platform from structural damage upon impact.

Sizing belongs in the design phase

Airbags should be incorporated during the initial platform design phase, in close collaboration with us, to match the system to the fuselage structure and mission profile. They perform best when descent is vertical and predictable. Designed incorrectly — particularly for parachute-assisted recovery with wind drift — an airbag may behave like a rolling ball and tip or rotate the UAV instead of suspending it.

Types

We provide lightweight, low-bulk, high-strength airbag solutions built to meet defense and aerospace standards. How the airbag is inflated determines inflation time, internal pressure, packed volume and transportability:

A further variant uses compressed air.

  • Self-inflatable: fills from airflow during parachute descent, adapted from paragliding harness impact protection. Light, but requires more storage volume.
  • Fan-inflating: ducted fans give rapid inflation, can be combined with self-inflation valves, and reach higher internal pressure and stability.
  • Pyrotechnic: similar to automotive airbags; fastest inflation at high internal pressure, single use seconds before impact, requires sensors and altitude measurement and may face transport restrictions.

What sizing requires

Tailored UAV airbags, cargo drop cushioning or recovery protection modules need four inputs: fuselage shape with the key impact zones, platform center of mass, location, dimensions and volume of the airbag compartment, and the maximum allowable impact G-force or the required energy absorption.

Frequently asked

Asked in technical terms.

What inputs does sizing a UAV airbag require?

Four: fuselage shape with the key impact zones, the platform center of mass, location, dimensions and volume of the airbag compartment, and the maximum allowable impact G-force or required energy absorption. We ask for these four inputs for tailored UAV airbags, cargo drop cushioning or recovery protection modules.

What happens if an airbag is sized incorrectly?

It may behave like a rolling ball. Particularly in parachute-assisted recovery with wind drift it can tip or rotate the UAV instead of suspending it. Airbags perform best when descent is vertical and predictable, which is why they belong in the initial platform design phase.
