DaVinci and His FLying Machines
Machine that flies by flapping wings
Ornithopter
Mass per unit volume of a given substance
Density
Birds flap their wings tp generate
lift and thrust
the rudder controls
yaw
Year of first powered flight
1903
Leonardo da Vinci's work that examined how birds fly and proposed mechanisms for flying
Codex on the Flight of Birds
The ability or tendency to float in water, air, or some other fluid
Buoyancy
When the four forces of flight are balanced, the flying object is said to have
the elevators control
pitch
What are the 3 dilemmas the brothers face
Lift
Control
Propulsion
Instrument that measures the angle of slope, elevation, or depression of objects with regard to gravity
Inclinometer
Principle that buoyant force on a submerged object is equal to the weight of the fluid that is displaced by the object
Archimedes Principle
Lift must overcome what other of the four forces?
weight
the ailerons control
roll
Where did they complete their first successful flight?
Kittyhawk, North Carolina
DaVinci's design that somewhat resembles a helicopter with wings that rotate
Air Screw
How do you make a hot air balloon descend
Open the parachute valve
Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a ?
decrease in pressure
why do we use wind tunnels to test aircraft designs
to test scale models
What did the brothers develop to keep the aircraft from spinning out of control?
Rudder
Year(s) DaVinci's notebook was filled with thousands of pages entirely on flight
1505-1506
Why do gas balloons fly
gas inside is less dense than air outside
Movement of a wing through the air creates ( ) on top of the wing as compared to the bottom of the wing, allowing for lift.
lower pressure
curvature of an airfoil is called
camber
Approximate horsepower of the engine?
8hp
