Control Surfaces
what does Yaw do to a plane?
helps the plane spin horizontally
Do wings of a bird help it glide?
Yes
What are the parts of the plane that juts out from the sides?
Wings
What is a pitch angle?
the angle that the blades on a propeller are tilted
What makes a hot air balloon rise?
When the air inside the balloon is heated.
what does the elevator control?
It controls Pitch
Do birds have stabilizers?
No
What part of a plane helps create the most thrust?
engine/propeller
What is a propeller?
a device with blades which is attached to a boat or aircraft that produces thrust
Air cools down inside the balloon and the balloon starts to shrink
What is Hot air Balloons Sinking?
An Aileron is used to.....
roll the plane, in other words it is helped to increase and decrease lift on one side.
What does a hollow bone represent as a plane?
Fuselage
What is the front of a plane (where the pilot will often stay in to control it) called?
Cockpit
How does a propeller create thrust?
When the blades (airfoil shape) spin they create a lower pressure in front of the propeller than behind. This lower pressure pulls the plane forward.
The ability or tendency to float in a liquid
What is Buoyancy?
Control Surfaces work because of....
Air pressure or bernoulli's principle
When a bird creates fast air is it low or high pressure?
Low pressure
What part of a plane helps control/change yaw?
Rudder and/or Vertical stabilizer
What is a rotor?
a sideways propellor that can proivde both thrust + lift for a helicopter
Objects that are less dense than water float
What is Archimede's prinicipal
Name all of the control surfaces, and what they control (ex. Yaw, Pitch, Roll)
Flaps: pitch, Aileron: roll, Elevator: pitch Rudder: yaw, Vertical Stabilizer: yaw, Horizontal Stabilizer: Pitch
Instead of a engine birds have what?
Pectoral muscles
What is the name that the body of a plane is called?
Fuselage
What is the 2nd rotor on the back used for?
It is used to stabilize the helicopter. The main rotor puts a force on the side of the helicopter, so the tail rotor counteracts that force. Without this the helicopter would spin out of control.
What carries the load in the Hot air Balloon
Wicker Basket
