Why is aerodynamics important?
Aerodynamics is one of the most important objects of study because they provide the bases for flight and the designing of not only aircraft, but also cars, spacecraft, and buildings. Aerodynamics work through the combination of three forces, thrust, lift, drag, and weight.
How does the shape of kite affect its flight?
Lift is generated by differences in air pressure, which are created by air in motion over the body of the kite. Kites are shaped and angled so that the air moving over the top moves faster than the air moving over the bottom.
What makes a kite aerodynamic?
Regardless of the design, a kite must conform to the laws of aerodynamics and embody three fundamental characteristics: an aerodynamic structure to gain lift from the wind, a tether to keep it from blowing away, and a bridle to direct the kite face at the proper angle to the wind.
Does the shape of the wings of an aircraft affects contribute to its main function and performance during flight?
The shape of an airplane’s wings is what makes it possible for the airplane to fly. That shape makes air flow over the top faster than under the bottom. As a result, less air pressure is on top of the wing. This lower pressure makes the wing, and the airplane it’s attached to, move up.
What is aerodynamic design?
Aerodynamic design begins with the wing and airfoil shape, then quickly extends to the full outer surface of the aircraft. Along with designing a smooth, low drag shape, aerodynamic design also includes providing good stability, control, and handling qualities.
What should you consider when designing for aerodynamic drag?
Properties of the Air Drag depends directly on the mass of the flow going past the aircraft. The drag also depends in a complex way on two other properties of the air: its viscosity and its compressibility.
How did the kite fly what did the kite need to fly?
A kite flies because the wind pushes it. The wind exerts a force on the kite. You can feel this force when you stand with the kite in the wind. The wind pushes the kite (and you).
What do kites need flying?
To fly, a kite needs to have enough lift to overcome gravity and drag. All of these forces – lift, drag, gravity, and the thrust of the wind come together in the kite at a place called the center of pressure. Not surprisingly, that’s where you tie your kite string.
What makes a kite shape?
To be a kite, a quadrilateral must have two pairs of sides that are equal to one another and touching. This makes two pairs of adjacent, congruent sides. You could have one pair of congruent, adjacent sides but not have a kite.
How do you design a kite?
- Draw your kite sail. Lay your paper or bag smoothly on a flat surface (if it is a piece of paper make sure it is folded in half), and mark three dots to form an isosceles triangle.
- Cut out the kite sail.
- Build kite structure.
- Attach your line.
- Make a tail.
How do aerodynamics work on a plane?
In aerodynamics, lift is produced by the difference in speed between an object and the air molecules around it. The motion of the air molecules above and below the surface of the wing creates the upward push of lift; this flow, in turn, helps keep the airplane aloft.
How does aerodynamics affect a paper airplane?
The aerodynamics of a paper airplane will determine the distance and ease at which it flies. Paper airplanes also use the forces of lift and thrust. When these four forces are used in balance, paper airplanes will fly longer.
How can we predict the aerodynamic performance of a kite?
Since the forces on a kite are the same as the forces on an airplane, we can use the mathematical equations developed to predict airplane performance to predict the aerodynamic performance of a kite.
Why do kites fly?
Kites fly because of forces acting on the parts of the kite. Though kites come in many shapes and sizes, the forces which act on the kite are the same for all kites. You can compare these forces to the forces that act on an airliner in flight and you will find that, replacing the thrust with the tension in the line, they are exactly the same.
What are the forces acting on a kite?
The magnitude of these forces depend on the lift coefficient, Cl, and the drag coefficient, Cd, which depend on geometric properties of the kite and the angle between the kite surfaces and the wind. The coefficients are usually determined experimentally for aircraft. But the aerodynamic surfaces for most kites are simple, thin, flat plates.
How do you learn aerodynamic forces?
An excellent way for students to gain a feel for aerodynamic forces is to fly a kite . Kites fly because of forces acting on the parts of the kite. Though kites come in many shapes and sizes, the forces which act on the kite are the same for all kites.
