Tethered drone solution
SARA idea has been stimulated starting by a patent filed (July,3th 2015 – #102015000030672 “Aeromobile drone e stazione di cambio batteria per tale aeromobile”) which is based on a proprietary RPAS multirotor tightly coupled to a base station (HANGAR) able to change the RPAS exhaust battery with a charged one. The same system could be modified by substitution of the battery change tool with a winch tool system winding a tethering cable for power supply of the aircraft.
Figure 1‑10 shows some CAD sketches of the design of concept in two configurations
The custom battery boarded on RPAS in the “HEM” configuration becomes a DC/DC converter in the “SAV-TV” configuration
The “killer application” for SAV-TV has been identified, by the Italian Coast Guard Stakeholder, inside maritime Search and Rescue applications, especially for night time operations tailor made on shipwrecks survivors rescue. The system will be designed to be tightly coupled inside the vessel, but also easily reusable for other markets. The conceived architecture realizes a deep innovation if compared with the process today used by users (overall Coast Guard Organizations), mainly for drastic reduction of operational time (and its related cost) and for increasing HR safety.
The main functions of the architecture of the tethered RPAS system are hereafter detailed:
