¶ Ported nozzle system fire-fighting UAV
Description: A large drone hovers about 15m (49ft) above, a fire-proof hose dangling from its belly. A pair of jets on either side of the hose pummel the flames with water as the drone operator controls the device from behind a fire truck, the device's water source. In about two-and-a-half minutes, the fire is out.
The 21kg (46lb) drone, called Sap (for "ported nozzle system" in Portuguese) is one of the newest tools in the battle to beat back extreme wildfires. The drone is lightweight, easy to operate and nimble at low altitudes. With a wingspan of 2.14m (7ft) and made primarily of carbon fibre, can swoop into places that are too dangerous or too difficult for firefighters to enter, says Carlos Viegas, a mechanical engineer who heads the University of Coimbra’s Field Tech Lab and co-led the project.
