Hearthstone arena

The Hearthstone arenaengine of the aircraft has always been one of the topics that passengers are most concerned about. Especially when the flight is smooth, people tend to wonder if there is a problem with the engine, can it be reversed to avoid accidents. However, in reality, engine reversal is not a safe operation. So, what exactly is the engine reversal? Why can't it be carried out easily? Engine reversal Engine reversal refers to the reversal of their rotation direction from the propulsion state to the braking state after the engine is turned on. Some airlines use reversal technology after the plane lands to shorten the taxi distance of the plane. When the plane lands, the pilot will push the accelerator to the maximum and then pull down the reversing lever to reverse the direction of rotation of the engine.In this way, the braking force of the aircraft will be strengthened, reducing the taxiing distance and brake wear. However, it is worth noting that reversal is only a technical means after the plane lands. In normal flight, reversal is not allowed and is also very dangerous. Because reversal will lead to aerodynamic and structural problems, damage the engine of the aircraft, and increase the risk of accidents. The danger of engine reversal. First of all, the reversal will lead to aerodynamic problems. When the plane is in normal flight, the compressor and turbine in the engine will suck in and accelerate the air. If the engine is reversed, the conveying airflow after twisting will increase the angle of attack, limit the take-off and landing speed of the rectifier, and also weaken the force on the wing, thus increasing the risk of aircraft crashing. Secondly, reversal will also lead to structural problems. During normal flight, the air inhaled by the engine will cool their parts and components.The reversal makes the engine heat up quickly, accelerating the wear and fatigue of mechanical parts, thus shortening the life of the engine, and even causing the engine to crack or explode. In addition, reversal will also bring risks. When the speed of the aircraft exceeds the reversal limit, even if the crew tries to reverse the engine, they cannot reverse it. And the ability to slow down the engine in reverse will increase the risk of cutting the belt when the plane takes off. Therefore, if there is any problem with the aircraft in normal flight, reversal should not be a desirable solution. In recent years, some new technologies have been introduced into commercial aviation, such as engine taxiing, to reduce the taxiing distance of aircraft. Engine taxiing Engine taxiing is a technique that reverses one or more engines to increase braking capacity before the plane lands and stops completely. Unlike reversal, this method isTurn the engine to a position where the aerodynamic and structural effects of the engine are minimized, so as to shorten the taxiing distance without damaging the engine. In engine taxiing technology, the taxiing speed of the aircraft will be significantly reduced, thus increasing the braking capacity. The pilot must perform engine taxiing in time after the plane lands in order to reduce the taxiing distance of the plane. Conclusion In short, engine reversal is not a solution for safe flight. Even when sliding, it is necessary to use professional technology instead of starting the reversal function easily. Therefore, pilots should use engine taxiing techniques as soon as possible after landing to obtain better braking results and shorter taxiing distances.
