Applied Studies
Development of project
The present solution was reached after performing a series of tests for the best use of internal static pressure, until the present diameter of a 450 mm cylinder was arrived at, and a pressure allowing us to keep the system efficient even with gusts of wind up to 80 km per hour.
Another problem that had to be solved was the gradualness of inflation of the cylinder, and in fact the solution to this problem was also the subject of a patent application If an adequate solution had not been found, the cylinder would have tended to inflate horizontally on the ground, before rising. This inevitable condition would lead to problems of bulkiness and difficult management in certain conditions (such as, for example, performance in mud, or in case of road accidents). Moreover, it would be almost impossible to straighten the cylinder under windy conditions. The solution adopted with the E.I.L.®System allows progressive vertical inflation of the cylinder and lets the operator control it even in extremely windy conditions.

Tests
All testing was performed with Digifly FAS9000 equipment, used for testing and recording functioning parameters in light aircraft.
The results of different configurations were monitored according to the following parameters: external temperature, CHT, EGT, alternator temperature, oil temperature, static pressure, dynamic pressure, air leakage, alternator rotation. Moreover, specific tests have been made in order to study the System in windy conditions.
