Model Parachute Design
A device used to slow down a falling object. We use them to safely fall from high places, like aircraft.
What is a parachute
The rising and falling of a hot-air balloon is controlled by
What is a burner that heats the air.
The force that allows a gilder to fly
What is lift.
The upward and downward motion of the plane’s nose.
What is pitch.
the main body of an aircraft
What is the fuselage.
The force that pulls us down to the ground when we jump out of a plane
What is the force of Gravity
The air inside a hot air balloon must be
What is less dense than the air outside the balloon.
The force that propellers generate
What is thrust.
The upward and downward motion of the plane’s wings.
What is roll
The back edge of the wings that are hinged flaps and help the plane to turn
What is the ailerons
The speed a parachute slows us down to
What is 290 km/h to 28 km/h.
The hot air balloon goes up by
What is heating the air inside the balloon.
The modification that can improve flight in a glider
What is streamlining.
What is wing improvements.
The part of the plane that controls Yaw
What is the rudder.
The horizontal part of a plane tail
What is the horizontal stabilizer.
A parachute works by
What is catching air to increase air resistance, which slows down our fall. A parachute increases our drag as we fall and makes us less aerodynamic
The principle that allows a hot air balloon to float in the air
What is buoyancy.
The reason why propellers create thrust
What is the difference of air pressure.
The wings of a plane interact with air to generate
What is lift.
The part of the plane that is at the rear of an aircraft, which controls the aircraft's pitch (vertical - up and down motion)
What is the elevator.
We increase air resistance by
What is increasing the surface area of the parachute.
The part of the balloon that is full of hot air
What is the envelope.
The air pressure on a propeller blade is higher on
What is the backside of the blade.
The force that spacecraft use to keep them aloft
What is thrust
The part of the plane where the pilots control the plane
What is the cockpit.
