Aerospace Dimensions Module 1
Vocabulary from Aerospace Dimensions "Introduction to Flight"
Terms in this set (59)
pertaining to air
relating to the forces of air in motion
the science of flight within the atmosphere
a combination of aeronautics and space
a mixture of gases that contains approximately 78% nitrogen, 21% oxygen, and 1% other gases
any machine that is capable of flying through the air; included are the ultralights, airplanes, gliders, balloons, helicopters, hangliders, and parasails
an aircraft that is kept aloft by the aerodynamic forces upon its wings and is thrust forward by a means of propulsion
a component, such as a wing, that is specifically designed to produce lift, thrust, or directional stability
a place on either land or water where aircraft can land and take off for flight
height above sea level or ground level expressed in units
the art, science, and technology of flight within the atmosphere
a person who operates an aircraft in flight
the curved part of an airfoil from its leading to trailing edge
a line drawn through an airfoil from its leading to trailing edge
a force which slows the forward movement of air behind a wing in flight
forces in motion
the natural force pulling everything to Earth
the front part of a wing or airfoil
the upward force that opposes gravity and supports the weight of an aircraft
the flow of air which moves opposite the flight path of an airplane
the force which moves an aircraft forward in flight
the upward movement of air ahead of the wing in flight
a spinning column of air that is created behind the wingtip as a result of air moving from an area of high pressure on the bottom to an area of low pressure on top
air in motion
a rising column of air that produces lift on a glider
"Newton's lift" is described in Newton's third law of motion that gives birds and aircraft their lift
Discovered the relationship between pressure and fluids in motion. Helped with the airfoil lift theory.
Theory that as acceleration increases, pressure drops, allowing the wings to move upward on an aircraft, causing lift.
Newton's 1st law of motion
an object at rest will remain at rest unless acted upon by an unbalanced, outside force.
Newton's 2nd law of motion
a force acting upon a body causes it to accelerate in the direction of the force. Acceleration is directly proportional to the mass of the body being accelerated.
Newton's 3rd law of motion
for every action, there is an equal and opposite reaction.
the wind that flows in the opposite designated direction of an aircraft.
the theory that as air flows over the top of an airfoil, it goes beyond and downward, causing a huge dynamic force.
the axis that runs up and down through an aircraft. causes the aircraft to turn side to side (yaw)
the line that runs from wing tip to wing tip. causes pitch, the ability to move the nose up and down.
the line that runs from the nose of a plane to the tail. causes roll.
controlled by the yoke of a plane when turning, it is located on the tips of the wings,
the height or distance above a reference plane. MSL, or AGL
fluid motion between regions of unequal heating
mass in a given volume
a mathmatical relationship between the distance an aircraft will glide forward to the altitude loss.
the average rate at which temperature decreases with an increase in altitude. average is 3 1/2 F per 1000 feet increase in altitude.
the art of staying aloft by exploiting the energy of the atmosphere
the atmosphere's resistance to vertical motion
usually a single-engined airplane that will pull a glider from the ground to an altitude where it can be released.
a waving action with strong up and down motions started as air moves across mountain ranges
instrument source to provide the height of the balloon above sea level
an aircraft that uses lighter-than-air gas for lift, with no built-in means of horizontal control
the heat source for filling the envelope with hot air
the rise or float on the surface of water or within the atmosphere
the top of the hot air balloon's envelope
the main body of the balloon, usually made of nylon, that is filled with lighter-than-air gas
a wicker basket, hanging below the envelope, used to transport passengers and propane tanks
one of several vertical panels that make up the envelope
the name of the two French brothers who created the first successful, manned, hot air balloon in 1783
located in the top of the balloon's envelope that allows it to be deflated (when a larger area of deflation is needed, some balloons are equipped with a rip panel.)
a lightweight, low carbon fuel used in hot air balloon burners
an instrument which measures the temperature within the envelope
an instrument to determine the rate of climb or descent; sometimes referred to as vertical velocity indicator.
