Chapter 8 – Aircraft in Motion
Questions / Comments
THIS DAY IN AVIATION December 8 1938 — Germany officially launches its first aircraft carrier, the Graf Zeppelin. It was the only aircraft carrier launched by Germany during World War II and represented part of the Kriegsmarine's attempt to create a well- balanced ocean going fleet, capable of projecting German naval power far beyond the narrow confines of the Baltic and North Seas. Construction was ordered on 16 November 1935 and her keel was laid down on 28 December 1936 by Deutsche Werke at Kiel. Named in honor of Graf (Count) Ferdinand von Zeppelin, the ship was launched on 8 December 1938 but was not completed and was never operational.
THIS DAY IN AVIATION December 8 1940 — New York City experiences its first blackout and anti-aircraft exercise, around the Brooklyn Navy Yard.
THIS DAY IN AVIATION December 8 1964 — A United Air Lines “Caravelle” makes the first landing in the United States completely controlled by a computer (automatic touchdown).

Chapter 8 – Aircraft in Motion
Today’s Mission Requirements Identify the two basic types of engines Describe the different types of turbine engines Describe functions of typical aircraft instruments. EQ: Describe an aircraft in motion and how the axes of rotation, flight controls, flight instruments and engines contribute to understanding flight.
Aircraft Engine
Aircraft Structures and Components Engines Two types Reciprocating Turbine
Aircraft Structures and Components Reciprocating -internal combustion engine Principle of Operation Cylinder is where fuel is converted into energy Intake Stroke - SUCK Cycle begins with piston at top center of the cylinder Compression Stroke - SQUEEZE As crankshaft drives the piston upward in the cylinder, the fuel and air mixture is compressed
Aircraft Structures and Components Principle of Operation Ignition / Power Stroke - BANG As the compression stroke is completed and just before the piston reaches its top position, the compressed mixture is ignited by the spark plug
Aircraft Structures and Components Principle of Operation Exhaust Stroke - BLOW On the second upward stroke, the exhaust valve is opened and the piston forces the burned gases out
Aircraft Structures and Components Principle of Operation Propeller is the action end of an aircraft’s reciprocating engine It converts the useful energy into thrust as it spins around and around. SUCK, SQUEEZE, BANG, BLOW
Aircraft Turbine Engines Four Basic Types Turbojet Turbofan Turboprop Propfan
Aircraft Turbine Engines Principle of Operation Take small amount of air in at intake and accelerate it to extremely high velocities through the exhaust nozzle
Aircraft Turbine Engines Turbojet Uses fan-like compressor blades to bring air into engine and compresses it Rotor blades bring in the air and push it backward Hot gases strike the blades and cause it to spin rapidly Spinning turbine is what causes the compressor sections to turn
Aircraft Turbine Engines Turbofan Principle of Operation One or more rows of compressor blades extend beyond normal compressor blades Much more air is pulled in than in a turbojet Much quieter and more fuel-efficient
Aircraft Turbine Engines Turboprop Principle of Operation Combines the best of turbojet and propeller aircraft Turboprop uses a gas turbine to turn a propeller. The gas turbine turns a propeller with twice the power of a reciprocating engine
Aircraft Instruments
Aircraft Instruments Engine Instruments Tachometer Measures speed (how fast crankshaft is turning) Oil Pressure & Temp Gauge Pressure / temp of oil
Aircraft Instruments Flight Instruments Airspeed Indicator Speed thru air – (pitot tube) Aircraft Altimeter Read in ft of altitude and calibrated to atmospheric pressure (SL – 29.92mb) Turn-and-Slip Needle indicates direction and rate of turn Ball in glass – quality of turn
Aircraft Instruments Flight Instruments Vertical Velocity (vertical speed indicator / Rate-of- climb indicator) Rate climbing or descending Attitude Indicator Provides artificial horizon
