Flyability, the Swiss firm finest identified for making drones that may safely stumble upon issues attributable to its distinctive cage design, simply gave its flagship Elios 3 drone one thing that lots of its opponents can’t match: probably limitless flight time.
The corporate this week unveiled the Elios 3 Tether Energy Unit, a wall-pluggable floor energy system that sends juice up a 50-meter Kevlar-reinforced cable. That allows steady operation with out mid-mission battery swaps. The announcement coincides with the Business UAV Expo in Las Vegas this week, the place the Flyability tether system made its public debut.
“Our tether presents steady energy, so the drone might fly eternally,” Eloise McMinn Mitchell, Flyability’s vertical advertising and marketing supervisor mentioned in an interview with The Drone Woman. In fact, there are sensible limitations: pilots normally want a break after half-hour, and the onboard reminiscence maxes out after about two hours of knowledge seize.
By comparability, Flyability’s just lately launched high-capacity battery presents as much as 17 minutes of flight. The tether unit doesn’t substitute batteries — drones nonetheless ship with them by default — however for industries that demand hours of nonstop knowledge assortment, tethering is now on the desk.
Tackling the tether drawback
Drones on tethers aren’t new (Cyphy famously included tethers of their drones, which have been finally acquired by FLIR). Alas, tethers are notoriously awkward to fly in advanced environments (like darkish, underground tunnels, the place Flyability’s drones have been made to fly in). Flyability claims it’s solved that with an anti-flip swivel that connects the tether to the drone. The swivel permits the cable to mount from any angle with out destabilizing the plane, so pilots don’t must obsess over line stress.
“The drone flies as if it have been untethered,” Mitchell mentioned. “Rivals don’t but have an equal function, which implies their pilots consistently have to trace the tether’s place to keep away from crashes.”
The cable itself is 50 meters (164 toes) lengthy, Kevlar-reinforced with a 50-kilogram tensile power, and designed to outlive 1000’s of abrasion cycles towards sharp edges. It’s not the longest tether in the marketplace, however Flyability emphasizes its sturdiness and portability. The unit packs right into a wheeled case and helps 100–240V AC enter, making it globally appropriate.
Why tether, why now?
Mitchell says the push to construct a Flyability tether got here from buyer ache factors. New drone pilots usually discover managing flight time demanding, and mission-critical purposes like ultrasonic thickness (UT) testing demand longer flights. Flyability launched its UT payload in 2024, however battery limits capped its usefulness.
“The tether was our lacking piece within the non-destructive testing market,” Mitchell mentioned. “It makes the Elios 3 absolutely prepared for difficult NDT missions.”
Oil and fuel is already a key vertical, and Flyability just lately ran checks with Shell on an offshore platform. Regardless of the Elios being designed for indoor inspection, the tether enabled it to map difficult-to-access constructions on the underside of a deck. Mining, energy technology, maritime and utility infrastructure are additionally anticipated to be sturdy adopters.
Autonomy, ROI, and what’s subsequent past the Flyability tether
Whereas Flyability isn’t disclosing pricing of the Flyability tether, Mitchell mentioned it’s positioned as a premium accent reasonably than a default. Current Elios 3 customers can add it to their kits, and new consumers can customise bundles that blend and match tether models, high-capacity batteries, and payloads.
Flyability argues the ROI case is simple: tethering reduces downtime, quickens inspections, and removes human employees from hazardous confined areas.
“We’re anticipating a large affect, particularly when inspecting giant property like ship hulls and tanks the place hours of flight are required,” Mitchell mentioned.
The tether additionally performs into Flyability’s long-term aim of extra autonomous operations. With flight time constraints gone, the corporate can give attention to scaling up its analytics software program. Future developments might embody instruments to match inspection knowledge throughout flights.
The larger image
In a market the place uptime equates to security and price financial savings, the Flyability tether’s pitch of “limitless” flight is certain to resonate.
The Elios 3 tether might be on show this week in Las Vegas on the Business UAV Expo and once more at different 2025 drone occasions akin to in Milan at GasTech. There are additionally regional “DroneDays” demos deliberate later this 12 months in Chile and Australia.
