Introduction to Aerospace
An unbalance in these two aerodynamic forces causes an aircraft to ascend or descend?
What are Lift and weight?
An orbiting body large enough to become round by the force of its own gravity and large enough to dominate the vicinity of its orbit.
What is a planet?
An orbit that has an altitude of 22,300 miles and an inclination of 0 degrees.
What is a GEO?
In VEX V5 programming, this type of block is used to control motor speed.
What is a motor block?
This flight path was chosen for the Apollo program’s moon landing.
What is a Lunar Orbit Rendezvous?
The name of the airplane part that can be used to change the shape of the wings and increase lift at a low speed.
What are flaps?
The _____ syndrome is a scenario/prediction of a future cascading of collisions in a LEO orbit.
What is Kessler?
This space program’s objective was to provide detailed photographs of the moon and scout a landing site
What is Surveyor?
This VEX V5 sensor is used for detecting distance or proximity.
What is an ultrasonic sensor?
This orbital parameter must use a reference point in space because an Earth based reference point will move as the Earth rotates.
What is RAAN?
_____ is a motion about the longitudinal axis caused by ailerons deflecting in opposite directions and controlled by twisting the yoke.
What is roll?
Velocity is _________ at perigee in orbit.
What is fastest?
The International Space Station has an orbital period of 90 minutes. It is a ________ orbit.
What is LEO?
This Vex V5 program block is used to pause a program for a specific amount of time.
What is a "wait" block?
A Boeing 747 is flying at constant altitude and velocity. Lift = 3,723 kN. Thrust = 500 kN. Weight = 3,723 kN.The opposing thrust is equal to ________.
What is 500 kN
_____ is a forward-acting force which opposes drag and propels the aircraft through the air.
What is thrust?
The period of an orbit depends on this orbital parameter
What is Semi Major Access?
The space age began on October 4, 1957, with the launch of _____.
What is Sputnik I?
This VEX V5 sensor measures the rotational position of a motor shaft.
What is an encoder?
Because of its strength/weight ratio and high melting point, _____ is currently the most widely used material in aircraft production.
What is aluminum alloy?
The navigational system used to guide an aircraft to a runway during approach.
What is ILS?
This type of orbit would keep a satellite positioned over the same ground on Earth 24/7.
What ie GEO or geostationary?
For an aerial vehicle to attain sub-orbital flight, it must break through an altitude of _____ miles.
What is 100+?
The following command:
motor1.setVelocity(50, vex::percent);
sets the motor speed to _________.
What is 50 percent?
The Earth’s atmosphere is predominantly composed of this gas?
What us Nitrogen?
