How lightweight is the UAV parachute and what payload does it carry?

The complete parachute system weighs less than 800 grams and is designed for UAVs carrying payloads of up to 75 kg. It achieves a sink rate below 4 m/s, even at maximum payload capacity, setting a new benchmark for payload-to-weight efficiency in UAV recovery solutions.

What materials are used to achieve such low weight?

APCO uses a proprietary high-tenacity nylon 6-6 fabric weighing only 20 g/m², combined with advanced reinforcement techniques to deliver exceptional strength with minimal bulk. The canopy is a 35 m² cruciform/rectangular parachute with a drag coefficient above 2.5, ensuring a safe and stable descent profile.

How does the parachute reduce opening shock?

A cross-slider deployment system is used to reduce opening shock, resulting in measured opening loads of 2–3.5 g at 30 m/s, well within safe operational limits. The parachute is integrated into a fielded UAV platform and has recorded thousands of successful deployments with zero failures.

The challenge

Designing a UAV parachute system with an ultra-lightweight profile while maintaining safe descent characteristics posed a unique engineering challenge. The requirement was clear:

Meeting these requirements demanded materials and methods far beyond conventional UAV recovery solutions.

Total parachute weight under 800 g
Payload capacity up to 75 kg
Sink rate below 4 m/s

Ultra-lightweight materials

APCO employed a proprietary high-tenacity nylon 6-6 fabric weighing only 20 g/m² – a breakthrough in balancing strength and low bulk. Combined with advanced reinforcement techniques, this material enabled record-breaking weight reduction without compromising durability.

Advanced design and construction

The final configuration resulted in a 35 m² cruciform/rectangular parachute with a drag coefficient above 2.5. This design provides unmatched aerodynamic efficiency, ensuring a safe and stable descent profile even at maximum payload capacity.

Deployment innovation

To ensure reliability, APCO developed a cross-slider system that reduces opening shock. Flight tests confirmed 2–3.5 g opening loads at 30 m/s, well within acceptable safety margins.
