ALTAVE, a Brazil based leader in monitoring and telecommunications for large open areas, launched its ALTAVE Omni system at the Rio 2016 Olympic and Paralympic Games. For the games organizers, the tethered surveillance balloons became a key asset to monitor the safety and security of crowds. The high-definition cameras mounted on the balloons were capable of recording 360° views in the four main Olympic areas: Maracanã, Barra, Copacabana and Deodoro.
Cortland Company supplied Aerostat tethers for the Rio 2016 Olympic and Paralympic Games.
The Brazilian Ministry of Justice in partnership with ALTAVE commissioned the use of heavy duty balloons, known as aerostats, as a vital security measure amid a background of high crime rates, political problems and uncertainties about the zika virus and economy in Brazil. It was necessary for the aerostats to be suspended 200 meters above the ground to provide a 24/7 eye in the sky to counter any criminal activity or potential terrorism at the games. Each balloon needed to provide power and data transfer capabilities for high value camera equipment, and had to be tethered using materials which would secure the balloons but not weigh them down.The Solution
The Cortland team used its experience as a global manufacturer of customized cables and assemblies to provide the tether solution. The aerostat tethers had to reliably supply all power and signals through a single electro-optical-mechanical tether for each balloon. Further critical design input characteristics were the tethers needed to be as small and light as possible. A smaller diameter tether would limit the negative effects of drag, while minimized tether weight would lessen the burden on limited resources that keep the balloon buoyant.
Cortland designed and built a tether with customized electrical and optical components which would not part or break, and which would be able to take the working load. A standard tether could have stretched or broken, while a heavier tether would have required a larger balloon. The team used a synthetic strength member composed of one the lightest weight materials known to man.
The tethers were developed in just a few weeks time, with samples supplied for testing ahead of the tight Olympics time frame. In the end, a series of 10 customized composite tethers with electrical and fiber optic connectors and synthetic strength members were delivered to Rio de Janeiro in time for the start of the games in August 2016
Bruno Avena, director and co-founder of ALTAVE, said: “Our aerostats performed a different role to other airborne security measures like helicopters or drones, as they were a 24/7 solution to capture the full-picture continuously, complementing the security process to keep athletes and spectators safe.
Cortland provided the expertise to develop one of the lightest and thinnest tethers possible. Their role was crucial in the support of our milestone work at the largest sporting event in the world.”
For Cortland, the success of the project has resulted in continued business with ALTAVE.
