The technical field of the invention is the protection of plants or installations (e.g. a nuclear power plant) against voluntary or accidental impact of an aircraft (e.g., New York September 11 th 2001 event). This protection system is based on the use of a barrage net of cables; the net is mobile on ground rails and its height can be quickly adjusted; the net is supported by a number of aerostatic balloons. The barrage net is complemented by a wall closer to the installation to be protected. At least two concentric independent barrage nets are envisaged in order to cope with a double (or multiple) strike by two or more consecutive aircrafts. Along the barrage cable of each balloon a wind turbine and radar aerials are located with the purpose, respectively, of usefulness of the system in absence of threats and of automatic detection of threats and of net position control. |
