Flyability Elios


Pushing UAV boundaries, the Flyability Elios is the first collision-tolerant drone - ideal for the inspection and exploration of the most inaccessible places. 

Complete with a carbon fibre protective frame, the Elios allows users to fly in complex, cluttered or confined spaces, meaning they can get to places which could not previously be reached. 

This state-of-the-art aircraft can be utilised by a number of industries, including energy, oil, gas and maritime - helping to improve safety, lower costs and reduce downtime.

Key Features

  • Simultaneous full HD and thermal cameras, and adjustable tilt angle
  • Powerful LEDs for navigation and inspection in dark places
  • Quick and easy battery swapping
  • Live 2.4 GHz video feedback. The digital video downlink is ideal for beyond the line of sight missions
  • Carbon fibre protective frame is collision tolerant up to 15km/h. Elios bounces off and rolls on to obstacles to find its way, meaning you can access the tightest spaces without any risk of crashing. You can fly close or even in direct contact with humans without any risks of injuries
  • Modular design allows easy maintenance
  • Flyability software presents mission data for future reference. Once you’re done flying, you can extract the data recorded on the SD card, embedded on Elios, right away
  • The Elios Ground Station lets you pilot from a safe place. It is composed of a remote controller, tablet and purpose-designed ground-control application which gives live telemetry data and an SD live video stream captured by Elios

Benefits Of Using Flyability Elios

Increase Safety

Elios prevents the need for workers to enter hazardous places or face dangerous situations.

Reduce Costs

No need to pay out on scaffolding, rope access, or cranes. Elios collects images of the most complex and cluttered spaces.

Less Downtime

Elios is deployed and ready to gather visuals within a minute. Slash inspection time from days to hours. 
"The Flyability Elios is a fast decision-making tool which enhances safety and availability of our assets."

Helping A Range Of Industries

The Elios is dust and splash resistant, operational in environments between 0° and 50°C, and mistake tolerant so that it can be easily piloted by everyone.

Operational after a few hours of training, your personnel will quickly get up to speed with their piloting skills. 

Designed to fly indoors where few or no drone regulations apply, Elios will be smoothly integrated into your workflow. 

As such, the Flyability Elios can be used by a range of industry verticals. These include:

  • Energy Industry: Inspect boilers, heat recovery steam generators and other large structures.
  • Oil, Gas and Maritime: Inspect above-ground tanks, pressure vessels and ship holds.
  • Other Missions: Inspect and explore tunnels, roofs and furnaces, among other things.

Cutting-edge Wireless Communication

Elios is equipped with a cutting-edge wireless  communication system that provides a live video feedback  allowing the pilot to bring the drone to the most inaccessible  places up to multiple hundreds of metres beyond line of  sight.

The wireless communication  system offers a robust digital,  bidirectional, long range signal  transmission which includes a  video and data downlink – from  the UAV to the Ground Station –  and command uplink – from the  Ground Station to the UAV.

Using the 2.4GHz frequency band, it is possible to fly Elios more than 100 metres above the ground in a closed boiler with the pilot safely standing outside next to the entrance manhole.

Pilot From A Safe Place

Elios Ground Station is composed of a remote controller, a tablet and a purpose designed ground control application providing the pilot with live telemetry data, an SD live video stream captured by Elios, and the information and controls that you need to operate it efficiently and safely.

In addition to displaying the live SD stream received from the drone, Elios Cockpit displays live telemetry data, gives you access to a detailed status of your drone and let you adjust settings right from the application.

Key data includes battery life monitoring, flight time, camera exposure, time to the next service, video configurations and relative altitude, among other things. 

Endurance To Capture The Data

The Elios can achieve up to 10 minutes of flight time and the batteries can be changed quickly.

Case studies show that 10 minutes is sufficient for capturing all of the information you need, starting with a reconnaissance flight to inspect boilers, storage tanks or other structures. 

Based on the information gathered during the reconnaissance flight, further flights are planned to more deeply inspect defined points of interest through the capture of close up images.   

Bringing the drone back to the operators after each segment of the inspection allows  for reviewing the images in details and refine/update the inspection plan on-the-go based on actual data.

After each flight, batteries are swapped in seconds. Just remove the used one, insert a new one and you are back to flying again.

Case Studies - How The Elios Was Key

9,000 Euros Saved

Energy company Uniper used Elios to complete the inspection of a gas turbine stack at a major energy facility.

The Elios was used to fly inside the stack, flying past the baffles and inspecting the entire area in one mission. 

Designed to fly in dark and inaccessible spaces, Elios was uniquely equipped to provide views of the stack interior. 

With the footage from Elios, inspectors were able to gather all of the data they needed on the state of the surfaces and the mantle, looking at support brackets, welds, and bolts for potential problems.


The Results

Downtime: No downtime. Visual inspection performed in one hour instead of three days.

Costs: 9,000 Euros of direct savings (manpower, crane and scaffolding rental) for one hour of inspection.

Safety: No human entry in the stack. No related paperwork.

17 Days of Downtime Saved

Engineering company Plimsoll, in Brazil, is using the Elios to take a close look inside the hulls of large ships.

Using the Elios drone for use in confined spaces, a team of two was able to inspect six tanks in a single day, capturing enough data in the process.

The Elios saved time, getting to the inspection site in just a few seconds. It also increased safety, keeping staff away from danger.

Because the Elios carries its own light, the team did not have to ask the client to provide lighting inside of the tank. This meant that even more cost and time were saved.


The Results

Downtime: 17 days of downtime saved. Inspection performed in one day instead of 18.

Costs:  $20,000 of direct savings in manpower. No scaffolding required for visual inspection.

Safety: No human exposed to the risks of using ropes or breathing inert gases.
