Friction Drag What is Friction Drag? Friction is the resistance that happens when two things rub together—like air against an airplane. Friction is partly what causes drag. How Does Friction Work? When an object moves through air, the air closest to the object’s surface is dragged along with it, pulling or rubbing at the air that it passes.

Airplane turbulence: a pilot explains why you can relax Turbulence is merely a disturbance in a fluid called ‘air’ – similar to the waves in the ocean. And many things can cause these disturbances. And even though it appears to be mystical – because we can’t SEE the air movements – it’s similar to a sea-state – or even a bumpy road – which are easily observed.

- Any airplane engine, piston/prop, prop-jet, turbine, turbo fan, even rocket, produce thrust by accelerating a gas/fluid, (air, exhaust) rearward which creates an equal forward thrust. That exhaust is created by burning fuel in air or with oxygen, expanding the gas volume which accelerates it to velocities greater than the air coming in to feed the combustion.

Basic Aerodynamics & Theory of Flight Drag is the aerodynamic force that opposes an aircraft's motion through the air. Drag is generated by every part of the airplane (even the engines!). How is drag generated? Drag is a mechanical force. It is generated by the interaction and contact of a solid body with a fluid (liquid or gas).

Breaking the Sound Barrier with an Aircraft One of the extraordinary sights associated with this supersonic transition is the production of a sudden visible vapor cloud around the aircraft. The report of the photographers is that they snap the shutter when they hear the sonic boom, which certainly associates the cloud with the breaking of the sound barrier. But the photo of the B-2 below, which is slightly subsonic, blurs that distinction.

- 1. Pilots always get a lot of warning about air turbulence. There's no mystery about what air turbulence is: It's created by atmospheric pressure, jet streams, and the air that circulates in mountainous areas, as well as weather fronts and thunderstorms.

- Because the air is rarely still, the distance an airplane covers in an hour depends on which way the wind is going. Compared to cars on the ground, a Cessna 150 that is flying at 110 MPH may actually be going as fast as 150 MPH if a strong wind is going the same direction as the airplane ( tailwind ).

- As an example of when vectors are necessary, suppose a plane traveling at 300 mph to the north with no wind present encounters a westerly crosswind of 50 mph. The resultant velocity of the plane is the sum of the velocities of the wind and the plane.

- Journals And Magazines. The Web's Best Sites. Air resistance is the frictional force air exerts against a moving object. As an object moves, air resistance slows it down. The faster the object's motion, the greater the air resistance exerted against it. Air resistance affects all moving objects, from airplanes, rockets, and trains to car, bicycles, and even living things. The large surface area of a parachute increases the amount of air resistance the skydiver.

- And so aother=Fother/m=C which means that all accelerations should be the same, so only air drag gives advantage to the heavier car. Finally one more example to illustrate: Drop two balls exactly the same size, one is a nerf ball (very light) and one is a lead ball (very heavy).

Fear of Flying: Why Airplane Turbulence Shouldnât Scare You! The reason that airplane turbulence is the beginning of most flying anxiety is because it’s something that touches your senses in a very real way. You feel the plane moving around differently. You see the coffee cup shaking.You hear the pilot tell you to fasten your seatbelt.y fear of flying only comes through turbulence. The nanosecond that I feel a jiggle or a dip that’s it I become the most religious person in the plane, the head rest gets crushed I go into a trance won’t look or talk to anyone.

Aerodynamic force When an airfoil (or a wing) is moving relative to the air it generates an aerodynamic force, in a rearward direction at an angle with the direction of relative motion. This aerodynamic force is commonly resolved into two components :orces on an aerofoil. Aerodynamic force is exerted on a body by the air (or some other gas) in which the body is immersed, and is due to the relative motion between the body and the gas. Aerodynamic force arises from two causes:

- Turbulence is air movement that normally cannot be seen and often occurs unexpectedly. It can be created by many different conditions, including atmospheric pressure, jet streams, air around mountains, cold or warm weather fronts or thunderstorms. Turbulence can even occur when the sky appears to be clear.

What happens when an aircraft breaks the sound barrier? If the object has sufficient acceleration, it can burst through this barrier of sound waves and move ahead of the radiated sound. The change in pressure as the object outruns all the pressure and sound waves in front of it is heard on the ground as an explosion, or sonic boom.hen, just as the aircraft bursts through the sound barrier, the air is locally disturbed by the resulting shock wave and the condensation/vapor cloud disappears. Ensign Gay snapped his photo at the moment he heard the boom, just before the cloud vanished.

Air resistance force Air resistance force is the force of air pushing against a moving object. Air resistance force is a type of frictional force (refer to Chapter 5 of this unit). Like all frictional forces, the force of air resistance always opposes the motion of an object. Usually, the air resistance force is not very strong. When you walk, for example, you are affected by air resistance force, but it does not really slow you down.

The Dynamics of Airplane Flight Air is a physical substance which has weight. It has molecules which are constantly moving. Air pressure is created by the molecules moving around. Moving air has a force that will lift kites and balloons up and down. Air is a mixture of different gases; oxygen, carbon dioxide and nitrogen. All things that fly need air. Air has power to push and pull on the birds, balloons, kites and planes.

What are the White Streaks in the Sky? This has many words for it, the main two words are vapor trail or contrail. Contrails happen when the air flowing over and under the surfaces of the aircraft create wingtip vortices mix with the moist air caused by the exhaust of the engines. The white streams you see are not engine exhaust.

- Everything, even air, absorbs sound. One example of air absorbing sound waves happens during a thunderstorm. When you are very close to a storm, you hear thunder as a sharp crack. When the storm is farther away, you hear a low rumble instead.

The Dynamics of Airplane Flight Sound is made up of molecules of air that move. They push together and gather together to form sound waves . Sound waves travel at the speed of about 750 mph at sea level. When a plane travels the speed of sound the air waves gather together and compress the air in front of the plane to keep it from moving forward. This compression causes a shockwave to form in front of the plane.

- Thrust is the force which moves an aircraft through the air. Thrust is used to overcome the drag of an airplane, and to overcome the weight of a rocket. Thrust is generated by the engines of the aircraft through some kind of propulsion system. Thrust is a mechanical force, so the propulsion system must be in physical contact with a working fluid to produce thrust. Thrust is generated most often through the reaction of accelerating a mass of gas. Since thrust is a force, it is a vector quantity having both a magnitude and a direction. The engine does work on the gas and accelerates the gas to the rear of the engine; the thrust is generated in the opposite direction from the accelerated gas. The magnitude of the thrust depends on the amount of gas that is accelerated and on the difference in velocity of the gas through the engine.
