A bird is a _____
Living machine
The story of Daedalus and his son, Icarus
The two were imprisoned on an island. As an escape, they decided to make wings of sea bird feathers and beeswax. They were able to fly until Icarus flew too high and the wax melted and he died in the Aegean Sea
Joseph and Etienne Montgolfier did what

November 21, 1783
___________ were the first known powered aircraft with humans onboard
Balloons
______were the first aircraft to have directional control
Gliders
What did Marco Polo see in China and when
In 1299 he saw Chinese sailors attached to kites used at military observers
What are the phases of fight for birds
Ground phase, lift phase, flight
Dynamic lift is also called
Newtonian Lift
What is Newtonian lift
The downwash of air on the trailing edge of the wing
What did Bernoulli discover
relationship between pressure and fluids in motion became the cornerstone of the theory of airfoil lift
As the speed of a fluid increases the pressure_____
Decresses
Newtons first law
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Newton's Second Law
A force acting upon a body causes it to accelerate in the direction of the force. Acceleration is directly proportional to the force and inversely proportional to the mass of the body being accelerated
Newton's third law
For every action there is an equal and opposite reaction
Which of newtons laws explains lift
3rd
The curve on the top of the wing is called_______
Camber
Define relative wind
The airflow the airplane experiences as it moves through the air
What part of the airfoil splits the air
The leading edge
What is the Coanda effect?
a fluid sticks to the surface it is flowing over, following the surface as it bends
Define angle of attack
The angle between the direction of travel and the relative wind
What are the four forces of flight
lift, weight, thrust, and drag
Define Lift
The upward force resulting from airflow over the wings that opposes gravity
Define Thrust
the forward force produced by the plane's engine
Define weight
A measure of the force of gravity on an object
Define Drag
Drag is the force or forces acting to oppose the motion of an object through a fluid
Movement around the _______ axis is called yaw
Vertical
Movement around the _______ axis is called roll
longitudinal
Movement around the _______ axis is called pitch
Lateral
The elevator is attached to the_______
Horizontal Stabilizer
A stabilator refers to______
Horizontal Stabilizer and the elevator
The rudder controls what
yaw
What do flaps do
Increase lift and drag (used on takeoff and landing)
A propeller is a spinning wing that produces
lift
The MQ-9 Reaper is a
UAV
UAV stands for______
Unmanned Aerial Vehicle
The Global Hawk is a
UAV
How far away is the sun?
93 million miles
When the sun heats the surface of the earth, the air around it heats up this causes the air to_____
Rise, it creates convection currents
Thermals provide glider pilots with_______
Lift
Define a glider
An aircraft designed to glide after being towed up to altitude
What is the Schweizer TG-4A?
Sailplane (glider) flown by the USAF acadmey
What instruments are in gliders
Airspeed indicator, altimeter, variometer, and a compass
What is a Blanik L23
A glider flown by CAP
September 1783, the Montgolfier brothers flew a balloon with what passengers on it
A sheep, rooster, and a duck
Balloons operate of the property of _________
Buoyancy
The container that holds the hot air is called the________
Envelope
What are hot air balloons powered by?
A propane burner
What is the basket on a hot air balloon called
The gondola
Hydrogen balloons can carry ____ lbs. for every _____ cu. ft. of hydrogen
60, 1000
Air baloons can carry ____ lbs. for every _____ cu. ft of hydrogen
17-20, 1000
How much does a hot air balloon weigh?
600 lbs
The panels that hot air balloons are called
Gores
What are hot air balloons made of?
a blend of nylon(strong and light) and dacron (heat resistant), a form of polyester
What are the four main instruments on an hot air balloon?
Temperature gauge (of the air in the balloon), altimeter, variometer, and GPS
combustion
the chemical process of burning
combustion chamber
an enclosed container in which fuel and air are burned for the production of energy
compression
the act of making a given volume of gas smaller
cycle
a recurring series of events; the airplane engine has four cycles, intake, compression, power, and exhaust
fuel
a chemical substance that is used as a source of energy; aircraft fuels include gasoline, kerosene, and propane
lean mixture
a mixture of gasoline and air in which there is less fuel and more air
magneto
an electrical generator that produces power when rotated
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.)
powerplant
a term which applies to the airplane engine and accessories
reciprocating
a type of engine that processes air and fuel by a back and forth movement of its internal parts
rich mixture
