Can you share some airplane flight horror stories?Sure. One horror story is about a sudden engine failure during flight. The plane started shaking violently and there was a lot of noise. Passengers were terrified, thinking the worst was about to happen. Fortunately, the pilots managed to make an emergency landing at a nearby airport.
A simple explanation of the flight principle of an airplaneAirplane flight was mainly based on the following principles:
1. ** Creating lift **
- For an ordinary airplane, the shape of the wings was designed to cause the air to flow at different speeds across the upper and lower surfaces of the wings. According to the Bernoullian principle, the greater the flow rate of the fluid, the lower the pressure. The upper surface of the wing was usually curved, so the air flow was fast and the pressure was small. The lower surface was flat, so the air flow was slow and the pressure was strong, thus creating an upward pressure difference, which was the lift force. In addition, the lift was also related to factors such as the angle of attack (the angle between the wing chord and the relative airflow speed).
- For helicopters, the large propellers stirred the air to generate lift when they rotated. When the lift was greater than the helicopter's own weight, the helicopter could take off, and the height could be adjusted by changing the speed of the propeller in flight.
2. ** Obtained Thrust Force **
- The aircraft could obtain forward thrust through the engine. A common type of engine, such as a piston-type engine (such as the early star engine), produced forward traction by driving the propeller to rotate. The turbine jet engine was a high-speed air compression engine. The air was compressed by the high-speed operation of the air intake. The combustion chamber sprayed oil and burned it. The gas rushed back to the turbine, which drove the air compression engine. The gas flow was ejected from the spout to generate thrust. Turbofan engines (turbine-fan engines) had two internal and external bypass passages. The ratio of the air flow rate of the external bypass passage to the internal bypass passage was the bypass ratio. The larger the bypass ratio, the more fuel efficient it was. It was widely used in aircraft flying at subsonic speeds such as passenger planes. Its main thrust could come from the air ejected backward at high speed from the external bypass passage. The turbine prop-jet engine was similar to the turbine jet engine, which was connected to a decelerator and drove an external propeller. It was mostly used in small or low-speed subsonic aircraft, but there were exceptions. There was also a propfan engine. There was no decelerator, and the propeller had a high speed. The fuel efficiency was further improved, but it was noisy. Turboshaft engines transmit power through a shaft and are used in helicopters.
3. ** Controlling the flying posture **
- The aircraft had three axes of motion: pitch, roll, and yawing. The roll was controlled by the ailerons, the pitch was controlled by the elevators, and the yawing was controlled by the rudders.
- If the helicopter only had the main propeller rotating, the body would rotate according to the conservation of momentum. Therefore, the small propeller on the side of the tail of the helicopter was used to prevent the body from rotating, so that the helicopter could turn left, turn right, or maintain a stable course.
4. ** Maintain center of gravity and balance **: The position of the aircraft's center of gravity needs to be reasonably distributed to ensure balance and stability during flight. Different types of aircraft structures and arrangements were designed with the center of gravity and balance in mind.
The novel "Hundred Years of Spaceship" is equally exciting. Everyone is welcome to click and read it!
How is the flight of the cartoon airplane depicted?In most cases, the flight of the cartoon airplane is depicted with a sense of adventure. It might have special effects like trails of smoke or shiny lights to make it more visually appealing. Also, the background and the way it interacts with other elements add to the overall charm.
This is by far one of my favorite stories! I like how the character actually notices her own change from flight or flight when she usually had been a flight to go suddenly into fight for herself and her creatures.
