【F-86】噴氣機時代的里程碑F-86“佩刀”戰鬥機，在朝鮮戰爭中屢次與米格-15空中對決|世界上第一架裝備空對空導彈的F-86“佩刀”戰鬥機，開啓了後掠翼超音速戰機新篇章。

In the Korean battlefield decades ago, both the United States and the Soviet Union were racking their brains to obtain samples of each other's fighter jets for research. I have to say that the US Air Force was lucky because two months after the Korean War ended , South Korea on September 21, 1953 Some pilots at Gimpo Air Force Base were looking at the photo film in the intelligence data room of the 4th Fighter Interceptor Group when someone shouted loudly. A MiG had just landed, a MiG had just landed, and the pilots rushed out the door and ran to the south of the airport. The runway scrambling to see the enemy's famous fighter jet and its pilot. A MiG-15 fighter jet parked there in the middle of 10 heavily armed F-86 fighter jets ready to go. Getting the coveted opportunity to test a MiG-15 and compare it to the F-86, the pilot ended up with a $ 100,000 bounty . Today we will talk about the North American F-86 "Saber" fighter jet, which has always regarded MiG-15 as a strong enemy on the Korean battlefield. The F-86 fighter jet is a single-seat, single-engine, swept-wing, subsonic jet developed by North American Airlines after World War II . The fighter jet is also the first generation of American jet fighters. It is used for air combat, interception and bombing missions . It is the first fighter to go supersonic in a dive and the first fighter in the world to be equipped with air-to-air missiles. It is also the first to fly at level. In 1944, the Pacific War reached a climax. The United States began to develop carrier-based jet aircraft . After World War II, with the German wartime research results on jet propulsion, rockets and missiles Continuing to advance , the United States is more eager to develop a higher-performance jet fighter. In fact, the original XP-86 plan of the United States used a barrel-shaped fuselage with air intake from the nose, a straight thin wing and a flat tail layout . The latest research has found that there are huge advantages of swept wings. For example, swept wings have great advantages at Mach 0.9. Flat-wing aircraft will be strongly impacted by compression effects at near-sonic speeds. Swept wings delay the generation of shock waves. And at supersonic speeds, the intensity of the shock wave is much smaller than that of a flat wing , making for better high-speed handling. Although these German studies are only theoretical, they have left American engineers working on ways to improve the performance of jet fighters . With the research ideas and directions, after several tossing, American engineers turned the Germans' theoretical research into reality . The "Saber" was born. Compared with the P-80 "Meteor" in the first generation of American jet fighters " The important progress of the "Sabre " and the F-84 "Thunderbolt" and other models is that its wings are swept back by 35°, which can make the aircraft break through the sound barrier and achieve supersonic flight . F-86 still has good control at high speed " The birth of the Sabre made important progress in the development of jet fighters It can be said that the Sabre fighter opened the swept wing The new chapter of the supersonic fighter F-86 fighter has a low- mounted swept wing Front three-point landing gear The engine air intake is located in the nose A fighter-type bubble canopy adopts a swept tail And the low-mounted horizontal stabilizer. To compensate for the low speed of the swept wing , engineers in North America installed automatic slats on the leading edge of the wing. The slats are fully automatically controlled to open or close according to the aerodynamic force received. When the slats slide forward, they can be opened. Accelerating the airflow over the upper surface of the wing increases lift and reduces stall speed At high speeds, the slats automatically close to minimize drag The relative thickness of the wingtip is 10% . The Sabre fighter has a length of 11.44 meters, a wingspan of 11.32 meters , a height of 4.47 meters, a wing area of ​​29.2 square meters, an empty weight of 4578 kg, and a maximum take-off weight of 7359 kg. The maximum flight speed is 960 km/h, the maximum range is 1060 km , and the weapons include 6 Browning M2HB 12.7 mm machine guns, which can also carry 908 kg bombs or 8 5-inch 127 mm unguided rockets . Change to 4 20 rockets for H-type The millimeter caliber gun F-86A was the first model of the F-86 family. The North American company received a production order for 33 aircraft in November 1946. The first A type was delivered to the US Air Force in 1948. Production ended in 1949 . Most used for testing and evaluation Did not enter military service In order to improve the takeoff and landing performance of unfinished runways, the US Air Force proposed a need for a larger tire design. The designation was changed to F-86B . However, the increase in tire size led to other related structures and systems . The change complicates the design work until the high-pressure tires and the new brake system are mature. This change requirement will no longer apply. The North American company proposes to split the previous order of 190 F-86Bs into 188 A-models and 2 C-models. After the U.S. Air Force agreed, the F -86B project was officially abolished . In the late 1940s, the U.S. government first faced the situation of being directly attacked by Soviet strategic bombers and began a huge air defense development program . -86D was born Nicknamed "Sabre Bulldog" The F-86D was the first single- seat all-weather interceptor, powered by a highly automated radar -guided interceptor system to provide all-weather operations, powered by a J47-GE-17 turbojet with an afterburner and had Microcomputer-controlled fuel distribution system When the pilot pushes the flight stick, the microcomputer determines how much fuel to supply according to the air intake , the operation of the engine and the afterburner to avoid unnecessary waste . The nose of the F-86D is also equipped with an AN . /APG-36 radar In order to free up the space for radar installation , the original air intake of the nose was moved down and changed to be similar to the F-1 The attack weapon carried by the 6 jaw-type air intake F-86D is a cluster launch of 24 2.75-inch "giant mouse" folding wing aviation rockets instead of traditional cannons. The rockets are all accommodated in the belly of a retractable launcher. Aviation The rocket was jointly developed by North America and the Navy. It was based on the German R4 rocket of World War II. The use of rockets as weapons was very risky at the time. So there was a more traditional 20mm cannon solution as a backup F-86E fighter based on the F-86A only . In front of the horizontal stabilizer, there is an extra bulge for covering the mechanical transmission, but there have been major changes in the interior of the aircraft. The E-type uses a J47-GE-13 engine with a thrust of 2360 kg. A total of 396 F- 86Es were produced. -86F replaces the F-86F, which is the main model of the day type. A total of 2247 F-types were delivered. Equipped with the J47-GE-27 engine with greater thrust , the combat radius when carrying two auxiliary fuel tanks reached 690 kilometers . This type of aircraft is equipped with a low-altitude bombing system. The F-86F fighter jet, which was specially used to drop the small tactical nuclear weapon MK12 atomic bomb , was once the car of General Amos , and the first model of the "Saber" series he experienced. The F-86F fighter jet used the J47-GE-27 with greater thrust . Engine This further enhances the performance of the Sabre fighter. The new and improved "full-motion horizontal tail" and "full-hydraulic irreversible" flight control systems enable the aircraft to still get the pilot's light and precise control during transonic flight. F The -86F "nimble" can fly to an altitude of 15,240 meters. It is a very suitable aircraft for fighting in the daytime, but it also needs a lot of fuel. The skills of Air Force pilots have been significantly improved. In addition to the United States Air Force, Canada , Greece, Italy, Spain and some other countries also use the F-86F for aerobatic performances. The F - 86H is a specialized fighter-bomber . Bombing system Installed with four 20mm cannons and capable of carrying nuclear weapons F-86 Sabre fighter of the 1950s With its more advanced radar , more flexible dive and low to medium altitude maneuverability compared to earlier MiG-15 It has a certain advantage, but the MiG-15 is superior to the F-86 fighter in terms of ceiling and climb rate. Therefore, Soviet pilots often fly the MiG-15 to approach the US formation from a high altitude and then dive down to attack. In this case, the US pilots generally The only option is to dive to a low altitude to escape, or try to drag the MiG-15 into a level fight after escaping a round of dive attacks . If the MiG-15 pilot chooses to climb back to altitude immediately after the dive, then the "Saber" Pilots will have nothing to do with this. After the Korean War, the F-86 entered service with the U.S. Allied Air Forces and became a major fighter jet for many Western nations. The last F-86 in service until 1993 It was only retired from the Bolivian Air Force in 2009, and it has created a record of service time for combat aircraft. Now with the replacement of jet fighters, the F-86 has long since retired from service , but as a classic jet fighter , the Sabre aircraft has created a variety of Its speed record and long-term and excellent service performance have established its position in the history of fighter jets goodbye
