Lighter-Than-Air CraftLighter-Than-Air Craft• Held aloft by

captive gases• Helium and Hot

Air• Density

1.23kg/m3

• Most energy efficient

Heavier-Than-Air CraftHeavier-Than-Air Craft• Most abundant

aircraft• Takes more

energy to keep them in the air

• Easier to control• Gliders, Planes,

helicopters

GlidersGliders• Fixed winged

aircraft• No power source• Still used today• Must use thrust

of another aircraft

AirplanesAirplanes• Works on the principles

of lift, gravity, thrust, and drag

• Can be agricultural or personal

• Speed range 7 mph to Mach 6.7

• Can have more than one wing (Biplane)

• Can seat hundreds of people

Control of Air CraftControl of Air Craft

• Yaw• Pitch• Roll

• Yaw• Pitch• Roll

HelicoptersHelicopters• More access to places• Vertical take off and

landing• Can “hover” in the air• Rotating wings (rotary

blades) make it fly• Tail (auxiliary) rotor

keeps the vehicle from spinning with the blades

ReviewReview

• What are the two types of Air Craft?• What are the 4 forces on a plane and

where are they located?• What are the three controls of a

plane and what do they control?• What does aerodynamic mean?
