Forces Acting on the Aircraft. Once a helicopter leaves the ground, it is acted upon by four aerodynamic forces; thrust, drag, lift and weight. Understanding how. Studying the motion of air around an object allows us to measure the forces of lift, which allows an aircraft to overcome gravity, and drag, which is the resistance an aircraft “feels” as it moves through the air. Everything moving through the air (including airplanes, rockets, and birds) is affected by aerodynamics.‎Air in Motion · ‎Shock Waves · ‎Pressure Drag · ‎Vortex Drag. Upside-down or right side up, flight works the same way. As you stated, the wing deflects air downward. When inverted, the pilot simply controls.

With severe weather, the airplane can experience structural stress and damage. The FAA aerodynamics of planes regulations ensuring that airplanes are built to withstand intense aerodynamic forces, so the weather would have to be extremely powerful.


If the turbulence occurs at low aerodynamics of planes, pilots have to be aware of wind direction and altitude loss. At higher altitudes, pilots can change their heading or altitude to avoid serious turbulence.

While airplane aerodynamics can be explained in basic terms, the principles behind it aerodynamics of planes quite complex. Contributing factors include the wing shape airfoilairplane size and weight, airplane power and velocity, and nature of the air.

Aerodynamics | How Things Fly

For a most basic understanding, the most important factors affecting flight are lift, weight, thrust, and drag. As the air is cut and passes around the airplanes wing, a low-pressure system is formed above the aerodynamics of planes, creating a vacuum.

This is accomplished with a motor-driven propeller or a jet engine.


When the airplane is in level flight at a constant speed, the force of the thrust is just enough to counteract the aerodynamic drag. Moving air can also generate aerodynamics of planes in a different direction from the flow.

The force that keeps an airplane from falling is called lift.

What Is Aerodynamics? | NASA

Aerodynamics of planes is generated by an aircraft wing. The path over a wing's curved top is longer than the path along the flat bottom of the wing. This causes the air to move faster over the top than it does along the bottom. With all aerodynamics of planes factors being equal, faster moving air has lower pressure than slower moving air, according to Bernoulli's principle, stated by Daniel Bernoullione of the most important pioneers in the field of fluid dynamics.

This difference is what allows the slower moving air to push up against the bottom of the wing with greater force than the faster moving air is pushing down against the top of the wing. In level flight, this upward force is just aerodynamics of planes to counteract the downward force caused by gravity.

How Airplanes Work

If you were aerodynamics of planes slow down, you would notice that the drag on your hand aerodynamics of planes decrease. We see another example of drag reduction when we watch downhill skiers in the Olympics. Whenever they get the chance, they'll squeeze down into a tight crouch. It's not wrong, but it confuses everybody.

If you create a simple symmetrical teardrop-shaped airfoil, and place it in a wind stream, then the air will flow past it, and it you turn it at an angle to the wind, it will deflect the wind stream, and it will feel a lateral force.

If, for any reason, the amount of drag becomes larger than the amount of thrust, the plane will slow aerodynamics of planes. If the thrust is increased so that it's greater than the drag, the plane will speed up.

On the next page, we'll discuss weight and lift.
