For years, pilots have been complaining that their planes felt like they did not want to land immediately before they could touch down. Most of them argued that their planes tended to feel as if they still wanted to continue with the journey even after the pilots tried to bring them to a stop. This phenomenon has been discussed through physics and some light has been shone to this phenomenon. Continue reading this article to learn about some of the things that happen as a result of the ground effect.
This phenomenon has been studied by a number of professionals and lecturers from big universities and they all have come to one agreement about some of the things that result from the ground effect. Their studies are based on explaining why most aircrafts tend to refuse to come down during flight. Most of them concluded that this was due to the air that was trapped between the wings of the aero plane. The landing surface of the plane also does the same thing done by the wings of the plane. They continue to explain that when the aero plane is about the surface of water or the ground, there is a change that is observed.
The 3D change in the flow of air around the flowing airplane also tends to explain the things that happen when the plane tends to be reluctant when it comes to landing. The surface of the plane also limits the flow of air. Both the upwash and downwash of the wing are interfered with by the surface of the plane. Therefore, the only time when the ground effect is observed is an interference exists between the ground and the wings of the aircraft. Some of the things that determine the ground effect is its closeness to the ground and some of the characteristics of the wings that are related to the flow of air around the plane.
Upwash and downwash of the wing are reduced when the ground effect is present. For the plane to continue flying upwards, a huge mass of air is pushed downwards towards the ground. In addition, in order for the plane to continue flying upward, the pressure above the plane pane is altered and the air below the plane pushes is upwards and therefore the plane continues to fly at higher altitudes. Nevertheless, the biggest determinant of whether the plane will move upwards is the amount of air that is pushed downwards by the plane when it is taking off. Among some of the things that are actually altered by the ground effect include the thrust of the plane versus its velocity. The induced drag is also reduced by the ground effect and this in turn reduces the thrust of the plane.
