The Nexus by Indemnis
A reliable and proven UAV parachute recovery system that is designed to meet and exceed expected FAA standards for flight over people.
UAV Recovery Systems
Fail-safe solutions, without limitations.
The Nexus by Indemnis is the first UAV recovery system to be proven reliable in any failure situation. Designed to enable safe, regulated commercial flight over people and overcome the limitations of traditional parachute systems on the market.
A UAV in a failed state will enter a high RPM roll and tumble scenario due to the inherent instability of a multi-rotor aircraft. There is currently not a system on the market that can reliably solve the threat of entanglement, as they all use conventional parachutes. The Nexus is a deployment system made from high strength ballistic materials. It deploys the parachute system in 30 milliseconds, creating an equivalent speed of 75-90 mph which is great enough to overcome the rotational velocity caused by the roll and tumble, eliminating entanglement when the drone fails.
Our system was built to meet and exceed future expected FAA safety standards for flight over people and it was created as a risk mitigation tool for enterprise use. Our patent pending advancements in materials technology enables us to utilize a larger parachute allowing us to fall softly to the ground with less than 30J of kinetic energy.
We have spent thousands of hours in development, testing, and engineering to continuously refine the technologies that make our system work. Our material technology, proprietary air tank and valve system, partnered with our advanced automatous fall detection software is what has allowed us to build upon our advancements and create a reliable product for our customers that is unmatched to any system currently on the market.
Frequently Asked Questions
How does the Nexus work?
The Nexus is a ballistic parachute launcher. It is a welded tube, that is inverted and houses a parachute. When the drone experiences a failure, the Nexus deploys and inflates the tube to 30PSI in under 30 milliseconds. The rapid inflation of the tube throws the parachute at 90 mph, while also shielding the parachute lines during the deployment. Once fully inflated, the tube becomes a rigid extension of the airframe that physically moves the attachment point of the parachute lines away from the drone body and propellers, thus escaping entanglement and allowing the parachute canopy to open effectively 100% of the time.
What is the orange tube made of?
The tube is made from a composite material that contains Dyneema fibers. Dyneema is the strongest fiber in the world, it is fifteen times stronger than steel. Indemnis developed the patented technology to weld the Dyneema composite material. There is no other material on the market that would be able a ballistic launch of the same force and no other deployment method could launch the parachute with the same speed.
What actually triggers the Nexus?
The system includes both an automatic triggering system for deployment and a manual triggering device as an option.
Do you have a “kill switch“ or flight termination system to stop the propellers from spinning?
The Nexus has an integrated flight termination system (FTS) that stops the propellers spinning and reduces the risk of laceration injury to people on the ground. Regardless of whether a deployment is initiated automatically or manually, the FTS will stop the propellers from spinning.
Are the aerodynamics or CG affected?
Yes, but very minimal. Anything foreign put on an aircraft will affect the CG but the system is designed to minimize the effects on aerodynamic performance. The aircraft maintains flight maneuverability and there is no noticeable difference in flight characteristics under normal conditions.
Is there a loss in flight time loss with the Nexus installed?
On the Inspire 2 with an X5s on board, the operator will experience about 3-5 minutes of flight loss on the battery life on a single charge cycle (with fresh batteries).
Is there an audible warning on deployment?
Yes. After deployment, the Nexus will produce very loud beeping sounds to alert people below the drone has experienced a failure and is descending. The manual triggering device transmitter also has audible status updates.
How long does it take to install the Nexus?
The Nexus has quick release compression clamps that attach to the arms of the aircraft, depending on the model, and one cord that gets plugged in. This allows for a quick and easy 30 second installation each time it is used, with easy removal for transport/storage when not in use.
To retrofit the Inspire 2, the initial set up takes an additional 5 minutes to install and secure an electrical component. This process is only needed the very first time that you use a Nexus on the Inspire 2. The other platforms do not require this process.
Will the Nexus deploy in the event of a full power failure?
Yes. The Nexus harvests power from the aircraft during normal flight conditions but is a fully self-contained system that is designed to deploy in the event of a full power failure. Does not rely on the aircraft for operation and can deploy independently if necessary.
