The intervention consists in the design of the external lightning protection system (LPS) to be installed to protect the new SMR Radar in service of the Control Tower.
The lightning protection system was sized following the assessment of the Lightning Risk specific to the type of structure, the type of activity carried out, and in particular, regarding the risk of loss of public service.
The collection system is made up of 6 joint collecting rods arranged on the top of the Radome, and of 8 lateral rods placed along the circumference of the Control Tower.
The positioning of the collecting rods was carried out by using the rolling sphere method. This method consists in going to use a rolling sphere with a radius of 20 m which corresponds to a level of protection I.
