Name: AVIATION INSTITUTE OF MAINTENANCE LUBRICATING SYSTEMS WORKSHEET #2 Date: Objective: Diagram and explain the operation of turbine engine lubrication systems Presented below are the elements and criterion for satisfactory compliance of the students' objective. Given: Unlabeled diagrams of turbine engine lubrication systems, a turbine engine installation, and appropriate reference materials. Performance: The student will identify components of typical turbine engine lubrication systems, label diagrams to indicate fluid flows, and answer questions concerning turbine engine lubrication systems. Standard: Identification of components and descriptions of system operations will conform to supplied reference materials. Part 1: Answer the following questions concerning turbine engine lubrication systems. 1. How does a turbine engine lubrication system differ from those of reciprocating engines? 2. What classification of lubricant is used in turbine engine systems? 3. What are the two basic turbine engine lubrication system designs commonly in use today? 4. Explain the basic principle of operation of a pressure relief valve system. 5. Explain the basic principle of operation of a full-flow system. 6. In what two forms can oil be delivered to engine bearings through an oil jet? Lubrication System Worksheet2 04/10/14 Page 1 of 4 7. Which bearing in a turbine engine is most critical with respect to lubrication and cooling? 8. What is the primary purpose of a turbine engine vent system? 9. Where are scavenge pumps located in a typical turbine engine lubrication system? 10. How does a fuel/oil cooler operate? 11. During the operation of a fuel/oil cooler, is the heating of the fuel detrimental to engine operation?
