Basic Hydraulic Systems and Components
Subcourse Number AL0926 EDITION A US Army Aviation Logistics School Fort Eustis, Virginia 23604-5439 4 Credit Hours Edition Date: September 1994 SUBCOURSE OVERVIEW This subcourse is designed to provide instruction on the concept and operation of the basic components of the hydraulic system. It also describes the various components of a typical hydraulic system, their construction and functions, and their relationship to each other. When the term hydraulics is applied to aircraft, it means a method of transmitting power from one location to another through the use of a confined fluid. The functions performed by hydraulic systems in aircraft include assisting in flight control, extending and retracting landing gear, positioning flaps, operating hoists, raising and lowering cargo doors, and starting engines. The hydraulic systems used in Army aircraft are dependable and relatively trouble-free. The maintenance requirements are small in comparison to the work the system performs. This subcourse is to be completed on a self-study basis. You will grade your lessons as you complete them using the lesson answer keys which are enclosed. If you have answered any question incorrectly, study the question reference shown on the answer key and evaluate all possible solutions. There are no prerequisites for this subcourse. This subcourse reflects the doctrine which was current at the time it was prepared. In your own work situation, always refer to the latest official publications. Unless otherwise stated, the masculine gender of singular pronouns is used to refer to both men and women. TERMINAL LEARNING OBJECTIVE ACTION: You will demonstrate a knowledge of the basic components of the hydraulic system, including the devices which actuate, discharge, and control the flow of hydraulic fluid and those devices which sense, control, and limit hydraulic pressure. CONDITIONS: You will use the material in this subcourse. STANDARD: You must correctly answer a minimum of 70 percent of the questions on the subcourse examination to pass this subcourse.
