Abstract
The invention belongs to the field of aviation fuel oil system, and particularly relates to an oil transport and venting structure of an auxiliary oil tank. The oil transport and venting structure comprises an auxiliary oil tank (1) and a venting oil tank (2), the venting oil tank (2) is connected with a venting guide pipe (3) through a first venting joint (6) and is connected with a venting connecting hose (8) through a second venting joint (7), and the other end of the venting connecting hose (8) is connected with a venting oil return joint (11) connected with an oil return port of an engine. Being practically applied on a certain machine, the oil transport and venting structure of the auxiliary oil tank is good in arrangement, and is well coordinative with an existing structure of an airplane after being installed on the airplane additionally, mounting and fixing of the oil tank are good, no interference is caused, and oil transport and venting of the oil tank can be realized. When the airplane flies obliquely leftwards and rightwards, a vent is always arranged at the zenith, venting state of the oil tank is guaranteed good, and flight safety of the airplane is guaranteed.
Description
Technical field
The invention belongs to Aviation Fuel system field, particularly relate to a kind of service tank oil transportation and ventilation device.
Background technology
Certain type helicopter is in order to increase voyage, it is the design plan that aircraft increases the fuel oil oil reserve that service tank is installed in employing additional, installing service tank additional at existing aircraft, to relate to service tank be main oil tank oil transportation and main oil tank, service tank ventilation problem, aircraft does not consider to increase the design plan of service tank at the beginning of design, do not reserve corresponding interface.
Existing helicopter did not adopt service tank oil transportation and ventilatory function to be designed into together design plan, the ventilation of service tank, main oil tank separates, common design plan is that service tank is installed in passenger cabin, service tank is the main oil tank oil transportation only, and being connected to the main oil tank vent line by conduit above service tank is the service tank ventilation; The ventilation fuel tank is generally the main oil tank ventilation, is installed in the boot compartment, by conduit main oil tank is connected with the ventilation fuel tank, realizes the main oil tank ventilatory function.
Summary of the invention
Goal of the invention: a kind of service tank oil transportation and ventilation device are provided, can be main oil tank and service tank ventilation, can increase aircraft range for the driving engine oil return provides passage again.
Technical scheme: a kind of service tank oil transportation and ventilation device, comprise a service tank 1 and a ventilation fuel tank 2, on ventilation fuel tank 2, be connected with ventilation duct 3 by first ventilating joint 6, connect ventilation by second ventilating joint 7 and connect flexible pipe 8, the other end that ventilation connects flexible pipe 8 is connected to the ventilation back leakage connection 11 that is connected with the driving engine return opening, service tank 1 be provided with filler cap 10, below be provided with service tank oil transportation joint 13, service tank oil transportation joint 13 is connected with main oil tank oil transportation joint 12 by oil hose 16.
By cassette tape 14 service tank is fixed on the support on aircraft floor.
Ventilation connects flexible pipe 8 and is fixed in ventilation back leakage connection 11 by breather pipe jointing clip 9.
Beneficial effect: the present invention has carried out practical application at certain type machine, service tank oil transportation and ventilation device system layout are good, after being attached on the aircraft, coordinate good with the aircraft existing structure, the installation of fuel tank and being fixed well, no interference can realize the function that fuel tank oil transportation and fuel tank are ventilated.Aircraft is under the state of flight that tilts, and vent guarantees that all the time at vertex the fuel tank aeration status is good, guarantees aircraft flight safety.
