Aircraft Reciprocating Engine Lubrication Systems Aircraft Systems This is an oil designed for to be used when the aircraft is operated in a temperate climate (15°c – 30°c). temperature has a large effect on the viscosity of the oil. cooler temperatures result in the viscosity increasing (more difficult to pour) and warmer temperatures cause the viscosity to drop (easier to pour). The basic process is as follows. upon arrival, the cooler gets an initial inspection performed by shop foreman frank sierra. obvious repair needs are noted and green tags are attached to identify the parts (oil cooler, vernatherm, etc.). the technician (jorge ayala, in my case) engraves the work order number, part number, and serial number on.
Model Aircraft A Low Pressure Fuel Cooled Oil Cooler A Magnetic Chip The oil system on any airplane can be thought of as the lifeblood of the engine. take an in depth look at how oil is circulated, cooled, and cleaned inside o. Oil cooler 101. Step 1: install the va 190 hose to the 45° fitting in the engine's upper oil port as shown in figure 1. step 2: route the va 190 hose to the oil cooler as shown in figures 2 and 3. step 3: install the free end of the va 190 hose to the fwd fitting in the oil cooler as shown in figure 4. figure 1: at upper oil port. The oil cooler used with this aircraft’s opposed type engine is the honeycomb type. [figure 7] with the engine operating and an oil temperature below 65 °c (150 °f), oil cooler bypass valve opens allowing oil to bypass the core. this valve begins to close when the oil temperature reaches approximately 65 °c (150 °f).
