Hello everyone, I drive a water fire extinguisher. Look! Its white hull has large wings on both sides, four propellers, and something like a missile on the wings. Compared with an airplane, I can land on water. Compared with a boat, I have two more wings and can fly in the air. There are many seaplane brothers, some can take off from the sea at any time and participate in battles; some can quickly rescue ships in distress at sea; some can deliver supplies to sailing ships...

One day, When I landed the seaplane on the sea and closed my eyes to rest, a distress alarm sounded in the cabin. It turned out that a large forest in the northeast was on fire. I turned on the water pump and separated the fresh water from the minerals.

I taxied quickly on the seaplane, and white waves splashed on both sides of the fuselage. The seaplane gradually left the sea and flew towards the distant horizon.

When we came to the sky above the forest, we saw thick smoke billowing on the ground and flames reaching into the sky. Some firefighters were putting out the fire with fire extinguishers, and some were putting out the fire with brooms. The police were maintaining order, and ambulances were People came and went to the fire scene one after another to treat the wounded, and there were reporters on the front line reporting on the fire fighting situation. Seeing such a scene, I immediately turned on the sprinkler device and sprayed water on the area where the fire was the fiercest. Through the joint efforts of all of us, the fire that was raging in the forest was finally extinguished.

The trees and flowers seemed to be saying: Thank you for putting out the fire, otherwise we would have died. We returned to our station with a feeling of victory and joy, ready to engage in new battles at any time.

Hi, everyone! My name is seaplanes. I have a huge fuselage, long wings, tail, propellers, and landing gear. If I am a ship, I also have the characteristics of an airplane. If I am an airplane, my fuselage is like a huge hull. I float on the sea because of the huge buoyancy of the fuselage, and take off because of propellers and other things... My usage is to draw water from the sea to put out fires, and to take off from the sea to participate in battles at any time; it can also be used for sailing ships. It can transport supplies; it can also rescue ships in distress... I was invented by Frenchman Henri Fabre. Later, they gave up on me due to lack of money, and later the Vozan brothers, early French aviators and aircraft designers, re-created me. Children, now you know me!

Although I have such great abilities, many engineers made me appear in this world. Children, you must study hard and make progress every day to make our future generations more high-tech. Information on water fire extinguishers

In order to meet the needs of operations in Southeast Asia, the Japanese Navy began to develop water fighters for operations in areas without land airports. The 15th test water fighter (N1K1 "Strong Wind") developed by Sichuan West Company could not be launched in time due to the use of various advanced technologies. Therefore, the Navy ordered Nakajima Company, which shared the production of Zero, to transform the Zero War into a water fighter emergency. Engineer Mitake Shinobu was responsible for the design, using the Zero War Type 21 as the mother body and installing a pontoon to become a seaplane. The modification features are as follows: 1) Remove the landing gear and landing tail hook to reduce weight; 2) The bottom of the fuselage is installed like the 95 Water Reconnaissance A single pontoon of the same shape has a simple three-pillar shape to reduce air resistance; 3) The auxiliary pontoon under the main wing only uses one pillar; 4) Since the side area of ??the main pontoon in front of the center of gravity of the fuselage is larger, the vertical axis is increased accordingly. The tail area is increased and a slender stabilizer fin is added below to ensure directional stability and aircraft maneuverability.

5) In order to cope with the installation of the pontoon, a 330-liter fuel tank is installed in the main pontoon instead of the disposable auxiliary fuel tank. The prototype of the Type 2 water warfare aircraft first flew on December 8, 1941. Later, the fuselage and engine bracket were strengthened and put into production. The model name was A6M2-N. Allied code name "Rufe" (Rufei). Type II water warfare *** produced 327 aircraft. Due to the increased air resistance caused by the pontoon, the Type 2 water battle reduced the speed to 436 kilometers per hour. It did not have the flexibility of the Zero Battle, but only had the fragility of the Zero Battle body. It participated in the battle in the autumn of 1942 and was used widely. It was used in Type II water warfare from various islands in the South China Sea to the islands in the central Pacific and even the Aleutian Islands in the north. Among the warring countries in World War II, Japan was the only country that equipped and used water fighter jets on a large scale. These special fighters were deployed on the shoals of very small islands and atolls. During the war, these water fighter units provided air cover for Japanese transport forces (such as the famous "Tokyo Express") and cruised in the surrounding waters. , history has proved that it exerted certain specific effects in the early stage. However, faced with the threat of powerful Allied fighter jets in the later period, the Type II water warfare was more than fresh, but the combat capability was insufficient and it was unable to achieve major results. Facts have proved that the use value of water fighters is not as high as imagined.

The composition is as follows: Super Detective There is a super detective in our family, he is my grandfather. Every time I "commit a crime" I can't escape his eyes. One day, I came home from school and found that the adults were not at home. I was still thinking that this was a great opportunity to commit a crime. So I put aside my homework and read the Little People's Book. When I was halfway through the book, I looked up at my watch, ah! It's already six o'clock, and it's probably time for grandpa to come back. So I folded the page that should be there, quickly put the little book on the bookshelf, and started doing my homework. Sure enough, after a while, grandpa came back. When he saw how little I wrote, he suspected that I had committed the crime. The focus of the super detective is - TV set, little book. The "super detective" first walked to the TV, touched the TV, and found that there was nothing unusual about it. So, grandpa looked through my little book again and found that one page of my little book was covered with quilt. The key point must be that I read the Little Man Book again. He said to me, "Have you read the Little Man Book again?" "No." I said guiltily. Grandpa joked: "That means magic has bent one corner of his body." I lowered my head in shame. Why water can extinguish fire essay 300 words

It was a bright morning. My mother was cooking in the kitchen and poured a lot of oil. Suddenly, the oil in the pot started to burn.

I saw it and shouted hurriedly: Mom, put it out with fire. Not only did my mother not go. Still laughing on the side, which made me confused, my mother picked up the pot lid and closed it for a while. The fire is out. I asked my mother in surprise. Firefighters and uncles always use water trucks to put out fires. Why don't you put it out with water? My mother said with a smile: Firefighting does not always require water, especially when the oil is on fire. Because oil is light and water is heavy, if you pour water into the pot, the oil will fill up and the fire will not be extinguished. And it can easily cause bigger fires. My mother also told me that fire requires oxygen to burn. After the oil pan is on fire, cover the pan quickly. a while. The oxygen in the pot will be gone, and the fire will naturally go out. It dawned on me. If I build a seaplane, it will also play a new role. How to write a 200-word essay

Seaplane

One day in 2091, I leisurely drove a water fire extinguisher to the strange place. On the changed sea, I saw waves chasing one after another, like snow-white silver chains thrown from the sky, violently crashing against the rocks. There was only a "boom" sound. In an instant, the silver chains broke and changed. Became countless waves.

While I was admiring it, suddenly, a shark came out and patted me on the shoulder and said, "Hi! Brother, what's your name?" I replied with a smile, my name is Shuishui. The fire extinguisher is similar to the boat, but it has two more big white wings and four propellers. When we were talking happily, the distress alarm sounded. I reluctantly said goodbye to the shark, and then quickly flew towards the sky.

I came to the sky above the forest surrounded by raging fires. I saw the firefighter uncle was sweating profusely from work. I quickly pressed the red switch, and a large fire extinguisher stretched out from under the plane. The fire extinguisher We immediately started spraying water, and with the concerted efforts of all of us, we finally put out the fire. The firefighter uncle smiled and said to me: "Thank you, you helped us a lot this time." I said: "You're welcome, this is what I should do." After that, I pressed the green switch again, A super big bag stuck out from the plane, which was full of seeds. I scattered them throughout the forest, and the forest was filled with greenery again. Then, I flew to the sky again.

What I learned from today’s incident is that it is everyone’s responsibility to serve the people.

Seaplanes can be divided into three categories according to the design method of contact with the water surface:

Generally, small seaplanes mostly adopt pontoon design

Float planes are generally used by small aircraft. One or two pontoons are installed under the fuselage to separate the fuselage from the water. Some aircraft have pontoons on both sides of the wings. Small auxiliary buoys are also installed to prevent the aircraft from tipping to both sides and capsizing.

A seaplane designed with only one pontoon, which is located directly under the belly of the aircraft. The two pontoons are designed to be located on both sides of the belly of the aircraft.

Since the beginning of World War I, most warships above cruisers will carry one or more pontoon seaplanes to carry out long-distance reconnaissance, target search and error correction during artillery firing. These aircraft are usually parked on warships, and some are ejected from the take-off rails above the turrets. Some larger ships have exclusive slides or hangars to house these observation seaplanes. When the aircraft lands, it first lands on the sea near the warship, and then the crane on the warship lifts the aircraft back to the ship and places it properly for the next mission. This type of pontoon seaplane can also take off directly from the water.

Medium and large seaplanes mostly use airship designs, such as the American PBY, which also has wheels and can be operated directly on land

Airship

Airship (Flying Boat) It is generally a common design method for medium and large seaplanes. The fuselage is in direct contact with the water surface. There is no need to install additional buoys under the fuselage. Some aircraft models will also be equipped with auxiliary buoys on both sides of the wings.

Another derivative of airships is ground effect aircraft that utilize ground effect, but this type of aircraft is generally not included in the classification of airships. Please refer to the relevant entries for details.

Amphibian aircraft

Amphibian aircraft (Amphibian) refers to seaplanes that can be equipped with or have wheels themselves and can operate, take off and land directly on land. This type of aircraft It can operate on the water or at land airports as needed, so it is called an amphibious aircraft.
