Airbags are a critical component of advanced UAV recovery systems and are most commonly used on unmanned platforms that rely on parachute-based landings without traditional landing gear. Similar to automotive airbags, these military-grade inflatable energy absorption systems are engineered to protect the platform from structural damage upon impact, improving mission success rates and extending operational lifespan.
Purpose and Design Considerations
For optimal efficiency, airbags should be incorporated during the initial platform design phase in close collaboration with APCO Aviation Defense. This ensures the system is matched precisely to the UAV’s structure and mission profile. They perform best when the descent is vertical and predictable. when designed incorrectly, particularly for parachute-assisted recoveries with wind drift, the airbag may behave like a rolling ball on landing—tipping or rotating the UAV instead of properly absorbing the impact and suspending it.
Airbag Types for UAV and Defense Applications
We provide lightweight, low-bulk, high-strength airbag solutions, built to meet defense and aerospace standards:
Self-inflatable airbags
Inflate using airflow during parachute descent.
Adapted from paragliding harness impact protection technology.
Offers weight savings but requires more storage volume.
Self-inflatable
Fan-inflating airbags
Use ducted fans for rapid inflation.
May be combined with self-inflation valves.
Achieves higher internal pressure and stability.
Ducted Fan
Pyrotechnic-inflating airbags
Similar to automotive airbags.
Fastest inflation with high internal pressure.
One-time use, activated seconds before impact.
Requires additional sensors and altitude measurement.
May face transport restrictions due to pyrotechnic components.
Pyrotechnic
Compressed Air
