Hello all stemians, On this occasion I will share to you about does the concept of birds fly freely in the air? hope its usefull for us.
What influenced the movement of the bird?
The animals that fly in the air in a unique way. The animal's animal body has a large lifting force to compensate for the force of gravity.
One attempt to enlarge the lift style by using the wings. The same principle applies to airplanes. Bird wings have an arrangement light skeletons, sternum and strong muscles. The shape of the airfoil wings makes the air flow over the top of the wing faster than the bottom. As the wings are flapped, the air will flow downwards. The lower thrust will produce an opposite force so that the bird will be lifted up.
In terms of Physics:
From the physical side is:
• The air pressure on the surface of a body of pressure must be smaller than at the bottom" (Bernoulli). This makes birds fly in the air.
• Speed is also one factor that can make the birds can fly, accelerate the movement then the bird can fly higher and last in the air.
In terms of Biology:
• Birds have bones and a light frame arrangement
• Birds have strong muscles to control their wings
• Bird's flying time requires a lot of oxygen. This is supported by the breathing apparatus, the trachea. Birds have a great cardiovascular system. If in 1 minute the average human heart only beats 60-90 times, the bird can reach 1000 times per minute! The heart is used to pump blood in which there is oxygen.
Bird breathing path (on flight):
- Inspiration
Wings lifted - purse of korakoid fluid - Air enter abdominal air purse - lungs (partial) and purse (partial). - Expiration
The wings down - the purse of the corakoid pinched - the thoracic chest expands - Air is pushed out (turn of O2 and CO2)
Do you know???
The principle on the bird wing is applied to the wings of the aircraft, ie with the Bernoulli principle and Newton's III Law, especially on the airfoil-shaped winged aircraft as shown.
Newton's Law III
"If an object is working on a force against another object, then another object will work on the same force as opposed to the object."
The two forces are known for their action style and reaction force.
Bernoulli Principle:
The Bernoulli equation describes the basic concepts of fluid (liquids and gases) that increasing the velocity of a liquid or gas stream, will result in a decrease in the aqueous liquid or gas. That is, there will be a decrease of potential energy in the fluid flow.
Very educational. I like that you are thinking about birds.
Thanks

Very nice post - good job presenting the principles of flight in a very easily digestible format, nicely illustrated and cited as well. Happy to have found you - followed! Cheers - Carl
Great post! easy to understand - I like the diagram showing how lift is working with bird wings is the same as planes. Didn't know that even the way a bird breathes is impacting the flight.
