All over the world, all air travel companies are concerned about not damaging their capital and passengers. This plan prevents such risks to a large extent. In the sense that it is possible to plant the plane in such a way as to avoid the problems of the previous methods. The performance of this method is such that when the wheels or engines or any other part of the plane is damaged, it is not expected from the plane to land normally, and we are sure that the plane may harm itself and the passengers during landing. In the best case, this device can significantly reduce the friction from the airplane body, and for that purpose, the landing strip for the airplane should be defined in a different way. In the sense that the pilot has to see the landing strip stationary to remove the friction, this method is not possible, unless the landing strip moves at the same level as the plane and the pilot puts the plane on the runway like a helicopter. Only in this case can we save capital and human lives. Therefore, all aspects and risks of landing should be considered in order to provide a suitable solution. This plan has solved the problems in this case to a large extent and has given a logical answer to each case. In normal cases (the plane is not damaged), it is possible to carry out this operation considering the unstable atmosphere or the unsafe band. Another point that is not mentioned in the explanation is that after the plane sits on the runway and comes to a complete stop, in order to empty the plane, the runway slowly moves towards the back or the hangar, and after entering the stand, by means of the following special devices The body of the plane replaces the wheels and the plane moves backwards from the runway. In this design and process, it can be said that the chassis is the most resistant part of this device. In this part, strong and light nets are placed. These multi-shaped networks can prevent the body from breaking due to unexpected impacts. On the chassis, a separate and vibrating plate, but connected by means of hydraulic jacks under the plate or runway, is installed to neutralize the pressure on the chassis and the plane. When landing, the plane sits on rubber pillars to prevent the plane body from being scratched and damaged. These rubber columns should be made of compressed rubber alloy with twisted yarns, and to make these columns more resistant, thin plates of spring steel should be used in this structure. These springs give the columns more stability. The ends of the rubber columns that are connected to the lifting levers are made of hard aluminum metal. It can be said that the spring in the middle of the tire is connected to the hard aluminum and the rubber is injected on both the spring and the aluminum.The brake pillars and wheel support brake are also made of hard aluminum fabric. With the difference that a coating of compressed rubber is injected on the aluminum so that when the healthy wheels of the plane do not get damaged when they collide with it, but the pillars that hold the sides of the plane and the fins that hold the wings of the plane are made of compressed rubber only in the part where the fuselage or the wings of the plane are in contact. The parts are made of the same hard aluminum. It can be said that in this structure, only the front and back columns of the net are made of steel due to the high pressure that sometimes occurs, and all the main parts except the rails are made of hard aluminum. In the first stage, this device ensures the safety of the passenger’s flight, this plan, in addition to saving the passengers when the wheels do not open, can cause the least amount of damage to the plane.
