Question 1

Factors of Lift

Answer 1

Speed; increasing speed = increasing lift
Air density
Angle of attack or inclination: how the wing approaches the air
Angle of incidence; angle of wing in relation to the body of the aircraft
lift coefficient
stall: dangerous condition where lift is lost

Question 2

Types of unmanned spacecraft

Answer 2

flyby spacecraft
orbiter spacecraft
rovers
landers
communication spacecraft

Question 3

unmanned

flyby Spacecraft

Answer 3

Used to collect information; must be able to go great distances, store data & communicate back to earth

Question 4

orbiter spacecraft

Answer 4

Flies into orbit around a planet, take pictures and record information

Question 5

rover

Answer 5

Robotic vehicles delivered to a planet, land on the surface to take pictures and soil samples

Question 6

landers

Answer 6

Land on surface of planet, but are stationary
May be used to house rovers

Question 7

communication spacecraft

Answer 7

Placed in the earth’s atmosphere, relay communication between earth and rovers or orbiters
Also provide GPS capabilities

Question 8

Parts of the plane

Answer 8

wings (delta wings, straight wings), fuselage, flaps, ailerons, rudder, elevator

Question 9

fuselage

Answer 9

located on the rear of the wings, near the fuselage. Used during takeoff and landing

Question 10

ailerons

Answer 10

Located on the outside rear of the wings. Causes the plane to roll along its horizontal axis for turning

Question 11

rudder

Answer 11

located on the back edge of the tail, used to control side-to-side movement.

Question 12

elevator

Answer 12

also on back edge of the tail, used to control up-and-down movement.

Question 13

fuselage

Answer 13

central body of the aircraft, to which wings are attached
