  2. AEROSPACE DIMENSIONSAIRCRAFT SYSTEMS AND AIRPORTSMODULE 2 Chapter 1 - Airplane Systems After completion of this chapter, you should be able to: • Explain how a reciprocating engine operates. • Identify parts of the airplane engine when viewed externally. • Explain how a jet engine operates. • Identify basic cockpit-mounted powerplant controls. • Identify basic flight instruments.

  3. AIRPLANE SYSTEMSIMPORTANT TERMS - Speaking The Language of Airplane Systems • powerplant- a term which applies to the airplane's engine and its accessories. • reciprocating- a type of engine that processes air and fuel by a back and forth movement of its internal parts. • cycle- a recurring series of events. The airplane engine has four cycles, intake, compression, power and exhaust. • combustion- the chemical process of burning. • combustion chamber- an enclosed container in which fuel and air are burned for the production of energy.

  4. AIRPLANE SYSTEMSIMPORTANT TERMS - Speaking The Language of Airplane Systems • stroke-in the example of an airplane engine, it is the movement of the piston, within the combustion chamber, to its limits. • compression- the act of making a given volume of gas smaller. • Stoichiometric - a ratio of fuel to air in which, upon combustion, all of the fuel is burned. In energy terms, it is 15 parts air to 1 part gasoline. • rich mixture- a mixture of gasoline and air in which there is more gasoline and less air than needed for normal combustion.

  5. AIRPLANE SYSTEMSIMPORTANT TERMS - Speaking The Language of Airplane Systems • lean mixture- a mixture of gasoline and air in which there is less fuel and more air. • fuel- a chemical substance which is used as a source of energy. Aircraft fuels include gasoline, kerosene and propane. • meter/ metering- In terms of fuel for an engine, this is the process of allowing a precise amount of fuel to pass. An example would be a passageway that allows only so many molecules of gasoline to pass in a given unit of time.
