Basics of Aerospace
Define the term "aerodynamics."
The study of the properties of moving air and the interaction between the air and solid bodies moving through it.
Who is credited with inventing the first successful airplane?
Wilbur and Orville Wright. Wright brothers also suffice.
Which planet in our solar system is often considered a potential candidate for human colonization?
Mars
What is the speed needed for an object to break free from Earth's gravitational pull called?
Escape velocity
What is an artificial satellite?
A human-made object that orbits a planet, the sun, or the moon to collect information about it or for communication purposes.
The speed at which an aircraft exceeds the speed of sound called?
What is supersonic speed?
What is the mathematical law that describes how rockets accelerate in a vacuum?
Newton's Third Law of Motion
What was the name of the first manned mission to land on the moon?
Apollo 11
What is the name of the process where fuel and oxidizer are combined to create a high-temperature gas that is expelled to generate thrust?
Combustion
Is a robot, that scientists send to moons and planets to land on their surfaces and explore.
What is a rover?
What do we call the angle between an aircraft's wing and the oncoming airflow?
Angle of attack
Name the four forces acting on an aircraft during flight.
Lift, weight (or gravity), thrust, and drag
Which space telescope was launched by NASA in 1990?
The Hubble Space Telescope
What are the two main types of rocket propulsion systems?
liquid rockets and solid rockets.
This NASA mission was aborted after the rupture of a service module oxygen tank in space.
What is Apollo 13?
In aerospace engineering, what does the acronym UAV stand for?
Unmanned Aerial Vehicle
What is the critical speed of an aircraft, also known as the minimum speed required to maintain level flight?
VMC = Minimum Control Speed
What was the name of the first artificial satellite launched into space?
Sputnik I
What type of fuel is commonly used in rocket engines?
Liquid hydrogen and liquid oxygen.
It serves as a home where crews of astronauts and cosmonauts live. Is also a unique science laboratory. Several nations worked together to build and use it.
What is the International Space Station (ISS)?
What is the name of the line that separates Earth's atmosphere from outer space?
Kármán line
What is the part of the plane that reduces drag and generates lift?
What is an airfoil.
Which major space agency plans to build a Lunar Gateway for future missions to the Moon?
NASA
Expand the hot engine exhaust gases down to ambient pressure, transforming thermal energy to directed kinetic energy to produce thrust.
What is the nozzle?
Which space probe was the first to reach the outer planets of our solar system?
Voyager 2.
