<p>The invention relates to a mobile installation for the tests of the altitude system, used for verifying the response capacity of the altitude systems in the endowment of aircrafts. According to the invention, the installation comprises a chassis (S) consisting of a metallic framework (11), supported by some axles (12) on which there are mounted some wheels (13) for displacement and an orientable wheel (14), mounted within a curved fork (15), fastened to a framework (11) by means of a blank bearing (16) which allows the rotation in horizontal plane. Inside the chassis (S) there is placed a pneumatic circuit (P) consisting of some valves (1 and 3) for supplying either from a compressed air cylinder, or from a compressed air network, placed on a frontal panel (19), some pressure reducers (2 and 4) connected to another valve (5) which allows performing the variable pressure transmission, a differential manometer (10) which measures the altitude system response capacity, a filter (6) and a flowmeter (7). On a panel (20) on the back of the chassis (S) there are mounted a handle (22) for hauling and a connection (23) for coupling to a supply source, and in the front, on a horizontal panel (21) there are mounted some connections (24 and 25) which allow the connection of some flexible pipes (8 and 9).</p> |
