How does the harr fighter achieve vertical take-off and vertical landing

1. The magic weapon for the harr fighter to achieve vertical take-off and landing is a vehicle equipped with 4 steering nozzles and can be rotated 0- 95° pecasus turbine fan engine. It can provide lift by changing the jet direction of the engine nozzle.

2. Because the hare fighter adopts a jet reaction force, it is the reaction force lift generated by the engine's downward jet to overcome gravity to achieve vertical take-off and landing.

3. The pilot can change the flight attitude of the plane by adjusting the direction and angle of the nozzle. This kind of aircraft generally does not require a runway. There is a 35×35-meter open space that can take off or land. Like a helicopter, it is very suitable for taking off and landing on smaller islands or aircraft carriers.

4. Operation steps The operation steps of a squail fighter can be divided into three stages: take-off, flight and landing. Take-off The pilot enters the cockpit and makes various preparations, including checking the instruments, adjusting the seats and seat belts. Start the engine and preheat and self-check. Adjust the angle of the jet port and prepare for vertical take-off.

5. Britain's "Harrier" Britain's "Harrier" is a vertical take-off and landing aircraft that uses a deflected nozzle.

6. Jet backwards to make the plane fly forward normally. The process of vertical landing is that the plane jets down, and then the intensity of the jet airflow is slowly weakened, and the thrust is slowly weakened, causing the plane to descend → land on the ship. Send you a picture. Photo of vertical take-off of the U.S. X-32B vertical take-off aircraft. Pay attention to the downward hot airflow to blur the scenery.

Which is better, Mobil Pegasus 805 or Kunlun

1. Generally, it is recommended that you use Kunlun oil, of course you can If you want to guarantee that Mobil oil is genuine, you can use Mobil. The reason for using Kunlun oil is that Mobil has too many fakes: Great Wall Kunlun is a domestic brand, and Shell Mobil is an international brand.

2. Hello! Kunlun engine oil is better. Although both are the strongest in the engine oil series, I think the engine oil should be durable. Kunlun myself thinks that the color is pure, and it is more active! It only represents my personal opinion. If you don't like it, don't comment. Thank you.

3. In summary, if you value cost-effectiveness and domestic brands more, you can choose Kunlun Tianwei;If you pursue higher performance and purity and are willing to accept the price of international brands, you can choose Mobil Black Overlord. When choosing, you can decide the most suitable product for you according to your needs, budget and preferences.

4. Domestic engine oil is developing very well now, okay? Whether you are a novice or a veteran, as long as the engine oil is a regular brand, the model and viscosity are suitable for the engine, and I also use domestic engine oil (Kunlun lubricant). The effect is completely no problem. You should believe in domestic big brands.

5. Easy to use, high-end. It is an independent brand under PetroChina, and the quality is still good. Although the effect is not as good as that of Jiashiduo, Mobil and Shell, after all, there is also a price gap, so as long as the expectations are not too high, you can rest assured to use it.

6. The best brands of lubricating oil are Kunlun, Mobil, Shell, Casto and Bosch.Kunlun Oil Lubricant Branch of China National Petroleum Corporation is a directly affiliated enterprise of China National Petroleum Corporation. It is a professional lubricant company integrating production, research and development, sales and service.

X-47 ship-borne unmanned fighter

1. Northrop-Grumman's X-47 "Pegasus" is an experimental unmanned fighter. The X-47 was first part of DARPA's J-UCAS project and is now part of the UCAS-D project of the U.S. Navy, which aims to build an unmanned aircraft carrier-based.

2. The American X-47 unmanned aerial vehicle X-47 was developed by Northrop Gruman in the United States.Fan's experimental unmanned fighter, the initial version code-named X-47A, made its first flight on February 23, 2003, while the subsequent naval version code-named X-47B, made its first flight in January 2011.

3. The X-47B is an experimental unmanned combat aircraft (UCAV) developed by Northrop Grumman, an American defense technology company. The X-47 project is part of the J-UCAS program of the Defense Advanced Research Program, which is already part of the UCAS-D program of the U.S. Navy aimed at developing ship-borne unmanned aircraft.

Which model of Pegasus Lidar lens is better

Pegasus D2000+lidar2000.The laser sensor with light mass, long distance and high accuracy can achieve a measurement accuracy of 5cm, which can achieve the purpose of topographic mapping, earth square measurement and other mapping purposes. With Pegasus' self-developed high-precision combination navigation products. The engine of Pegasus D2000+lidar2000 is good.

IMX906 and IMX890 are both Sony camera sensors. Their main comparisons are as follows: Pixels: IMX906 has 12 million pixels, while IMX890 has 12 million pixels. Sensor size: The sensor size of IMX906 is 1/55 inch, while the sensor size of IMX890 is 1/8 inch.

Omron 7211 has a large test range and supports dual-sensing self-testing function. Personally, I think it's better.The differences between Omron 7211 and 7136 are: different test range, different arm circumference range, different support, and different weight. The test range is different. Omron 7211: The test range of Omron 7211 is 0-299mmHg.

First of all, Kangjia KES-22AS02, boil 2L of water for 6-10 minutes. The shape of this model is unique. It does not take up space on the table, and the workmanship is also very good.

mini8 can flash intelligently, but it can't be turned off, and there is no automatic light measurement function.

How many meters per second can the fastest fighter reach?

1. M is to fly 3,298 meters per second. The fastest pilot is the SR-71 "BlackBird", a high-altitude reconnaissance aircraft of the U.S. Air Force.

2. The fastest speed of a supersonic fighter can reach: a flight speed of 400 per second at an altitude of 12,800 meters, M=1015. Speed of sound: The speed of sound is about 340 meters per second. Mach: ultra-high-speed unit, the ratio of the speed of movement of an object to the speed of sound is Mach or Mach. Subsonic speed: the speed is less than 1 Mach.

3. The outer part of the MiG-17 has a 42-degree angle, and the fuselage is longer and streamlined, which eventually makes it an all-weather fighter that can reach 15 times the speed of sound. The second generation aircraft with the fastest flight in the world: the F-104 Starfighter.

4. The maximum speed of the plane is about 1,915 km/h, and the maximum flight altitude can reach 15,000 meters. Its unique vertical take-off and landing capabilities make it particularly widely used on naval aircraft carriers.J-10 fighter - a multi-purpose fighter in China, its development began in the 1990s.

5. Through calculation, it can be learned that the fastest flight speed of the J-20 reaches 866 meters per second, which is equivalent to Mach 6. This flight speed has exceeded that of advanced fighters such as F2 Su-35, and is only slightly slower than the MiG 31.
