dead loop - it aerobatics which has become the epitome of technological progress and mastery of aircraft pilots.9 September 2013 that trick was exactly one hundred years.The first person who has successfully completed the loop, is the pilot of the Russian Empire PN Nesterov.Loop in his performance was the first successful implementation of this trick.This successful attempt to make the maneuver undertaken long before this.The name of the trick was due to a number of failed tests which have resulted in death.
emergence of maneuver
For example, an American Jax on the plane design of the Wright brothers tried to make a vertical loop.However, the engine power was very weak to keep the plane at the top.After that date back several attempts to buttonhole, but the vast majority of them ended with tragedy.The design of the aircraft at the time did not allow to withstand such loads, which is why in the vertical lift or at the top plane just started to crumble.It should be noted that while there were even special regulations prohibiting pilots to make sharp turns and bank fragility due to high air vehicles.Some time even believe that a complete revolution in the vertical plane is simply impossible to fulfill.
After a series of unsuccessful attempts aeronautical engineer realized that for normal flying wheels up and return the aircraft to the starting point must be to create an absolutely stable mechanism.That is, the aircraft should be well balanced, and the point of aerodynamic drag and the point driving forces should be as close to each other (ideally - matched).
Features modern loop Nesterova
dead loop at the dawn of aviation is a challenge to the skill of the pilots and engineering.Today this figure aerobatics is widely used as part of the air show, as well as a means of training young pilots.This is because the performance of trick requires management skills training aircraft under varying loads, pitch, height and speed.Only fully experience the capabilities of its aircraft, you are ready to perform tricks.In addition, the loop laid the basis for the implementation of a number of other aerobatics, which are used both for skills training, as well as during the actual fight.
Loop is correct when all the points of the trajectory of the aircraft lie in a vertical plane, with the overload remains positive throughout the maneuver and shall not exceed the limit in which the plane is broken into a tailspin.
first half of the loop is performed by the thrust of the power plant, and picked up speed, the second - by the weight of the aircraft and its attraction to the ground and thrust.
loop Nesterova helicopter
first helicopter, which carried out the maneuver, was the Ka-50.The machine design allows for full 360-degree loop.However, such a maneuver is quite risky because the blade unit can be carrying shlestnutsya.Therefore, at an air show performed so-called "oblique loop".In this case the trajectory of motion of the helicopter is not vertical, but slightly tilted relative to the horizon.
ground loop
Nesterov loop can be performed also on the ground.So, in order to fulfill the car turn 360 degrees in the vertical plane, it is necessary to build a special track.With sufficient speed the car is easy to pass the highest point of the ring.The same applies to motorcycles.Such tricks are quite common in a variety of circus and entertainment Motor Show.
Thus, the plane does a loop the most sophisticated and beautiful.Monitor the implementation of this maneuver is really exciting.
