Autonomous brake-cooling system for aircraft
View Patent ↗The object of this disclosure is to cool the brakes of the landing gear of an aircraft. For this, it uses the air of the same air conditioning system of the airplane. The supply to the air conditioning system of the airplane can receive pre-conditioned air from outside by an air inlet in the lower part of the fuselage of the airplane to which an external equipment is connected. This air inlet has a non-return valve inside, which prevents the air from going outside. In order to extract the air from the air conditioning system of the airplane while it is on the ground, it is necessary to overpass the air valve. For this purpose, a tool that overpasses that valve from outside has been designed, and in this way, extracting and directing the air through connectors and tubes to the brakes, cooling them for a new takeoff.
1. A brake cooling system for aircraft, comprising:
a connector;
a tool configured to open an air conditioning valve of the aircraft, the tool comprising:
two plates that form a “Y” or fork, wherein the two plates are joined by a plurality of bolts;
a tube fixed to the plates;
a mobile tube attached externally to the fixed tube;
springs compressed inside the mobile tube; and
two triggers attached to the mobile tube; and
a duct system configured to connect an air conditioner to the brakes of the aircraft via couplings.
2. The brake cooling system according to claim 1 , wherein the tool further comprises an opening rod fixed to the connector by a clamp with bolts;
a lifting rod connected with a bolt to the opening rod;
a roller attached to the end of the opening rod; and
a handle attached to one end of the lifting rod.
3. The brake cooling system according to claim 2 , wherein the duct system comprises a main duct having a first end connected to the connector and a second end connected to a “T” connector, wherein the “T” connector connects to two secondary tubes, and wherein the secondary tubes also connect to two “L” connectors that connect two couplings to the brakes.
4. The brake cooling system according to claim 1 , characterized in that air is extracted from an air conditioning external system of the airplane.
5. An opening tool for valves, comprising:
two plates that form a “Y” or fork joined with a plurality of bolts;
a tube fixed to the plates;
a mobile tube attached externally to the fixed tube;
springs compressed inside the mobile tube; and
two triggers attached to the mobile tube.
