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.
Aircraft Gas Turbine Engine Lubrication System Components If your engine drinks a quart an hour, turns the oil black in three hours and routinely runs 240° f oil temps, you need an engine overhaul, not a larger oil cooler. parts scrounging is a time honored tradition in experimental aircraft building, but it pays to be cautious when un earthing veteran oil coolers from an a&p’s dusty shelves or at. The vernatherm is a. natural culprit to consider when dealing with oil temperature problems. note that oil temperature problems are usually of the “too high” variety. anatomy of a vernatherm. the center section, with studs on each end, extends or contracts according to temperature, moving the beveled seal into a seat. For example, the oil reaches operating temperature more quickly if the airflow is cut off during engine warm up. there are two methods in general use: shutters installed on the rear of the oil cooler, and a flap on the air exit duct. in some cases, the oil cooler air exit flap is opened manually and closed by a linkage attached to a cockpit lever. 0. sizing the oil cooler properly and installing it so that adequate air flows through are some of your more important firewall forward tasks. if these are done well, your oil temperature should remain between 165° and 200° in all but the most difficult hot weather climb situations. it is important to keep in mind that the actual oil.

The air cooled oil cooler is normally installed at the forward end of the engine. it is similar in construction and operation to the air cooled cooler used on reciprocating engines. an air oil cooler is usually included in a dry sump oil system. [figure 12] this cooler may be air cooled or fuel cooled and many engines use both. 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).
