Levels of internal pressure

The present solution was developed after performing a series of tests to optimise static pressure inside the supporting structure, obtaining the current cylinder diameter of 40 cm, and a pressure level that allows the system to operate efficiently, even with gusts of wind up to 70 km/h.

 

Inflation and vertical extension of the supporting structure

The patented EIL system allows the cylinder to inflate gradually and swell vertically. In fact, the structure is divided into sections by inner walls containing holes of varying diameters. Accordingly, the system creates a pressure differential between the various sections. Inflation is therefore gradual and vertical, section by section.

Without this system the tube would inflate horizontally on the ground before lifting upwards, which would create problems of space and would be uncontrollable in certain conditions (such as applications in muddy areas, or for road accidents). It would also be basically impossible to stand the cylinder upright in a strong wind. The solution adopted with the EIL® system allows the cylinder to be inflated gradually and vertically, and allows the operator to control it even in strong winds.

Safety systems

Special patented safety systems stop the supporting structure from deflating when the lighting unit is on, by means of pressure sensors, double fans and safety valves.


Tests

All testing was performed using equipment employed in the aeronautical field, to test and record the operating parameters of light aircraft. The results of different configurations were monitored according to the following parameters: temperature inside and outside the cylinder, CHT, EGT, alternator temperature, oil, static and dynamic pressure. Moreover, specific tests have been carried out in order to assess system behaviour with winds up to 150 km/h.
