Just an AK47 assault rifle made the Tang Empire make a lot of foreign exchange, and advanced aircraft such as Raptors and Hellfire are also among the exporters, with greater value.

According to the export principle of the Tang army, unless the military uses more advanced and advanced weapons and equipment, exports are restricted.

Previously, the Tang army only exported shrinking versions of Raptor and Hellfire series of fighter jets in terms of fighter jets, but in the past few years since the outbreak of World War II, countries have been imitating it, and there is a trend of becoming more popular.

Fighters such as Raptor and Hellfire were successively retired after ten years of service in the Tang army and turned to export. At the same time, the replacement aircraft were a group of new fighter jets with jet engines as engines.

According to algebraic classification, jet aircraft belongs to the third generation and have been studied by all countries, but only the Tang Empire is at the forefront and has developed real jet fighters.

Whether it is Germany's ME262, Soviet MiG3, or American XP86, although they have turned the aircraft into a jet type, which can theoretically fly 700 kilometers per hour, the actual test flight speed has not exceeded 600 kilometers per hour.

For the efficiency of propeller and jet aircraft, the aircraft speed is 700 km/h, and the efficiency of pure jet engines is lower than that of propeller engines because its propulsion efficiency depends to a large extent on its flight speed. Therefore, pure turbojet engines are most suitable for higher flight speeds. However, due to the airflow disturbance caused by the propeller's high blade tip speed, the propeller efficiency is rapidly reduced at more than 500 km/h. These characteristics make some aircraft flying at medium speeds adopt a combination of propeller and gas turbine engines instead of using pure turbojet devices - turboprop engines.

This is the real reason why the hybrid turboprop engine used by the first generation of Raptor fighters in the Tang Empire. At this time, Germany, the Soviet Union and the United States did not break out of this circle of thinking. However, after a long period of research and experiment, the Tang Empire used the world's top super wind tunnel to conduct a large amount of data testing, and finally broke through this barrier in 1941. It developed a jet engine that can make the Raptor fighter speed exceed 850 kilometers per hour.

The second generation of Raptors, the Tang army continued to use this code name and distinguished it with the second generation.

The new generation of Raptor fighters benefited from the rapid development of air compressor technology and gas turbine technology of the Tang Empire, and the two combined form the most critical core component of the jet engine.

In terms of aerodynamic layout, the Tang Empire took a shortcut. Zhang Meng personally drew a sketch of the swept-wing aircraft layout and handed it over to aircraft designers of the General Administration of Aviation for re-study and design. After testing the top-level super wind tunnel group, the second-generation Raptor jet fighter of the Tang Empire was able to achieve its first flight at the end of 1942 and was officially delivered to the Royal Air Force of the Tang Empire in March 1943 for verification.

When the Tang Empire and the Soviet Union signed the export agreement for the first-generation Raptor fighter jets, the Tang army began to produce the second-generation Raptor fighter jets on a large scale to replace the first-generation Raptor fighter jets served by the Tang army.

The appearance of the second-generation Raptor fighter of the Tang army has undergone a revolutionary change, which is completely different from the first-generation Raptor. Due to the installation of a single-engine jet engine and a swept wing, the layout of the aircraft wheels has also changed from the previous two front one to the first one and the second one.

A long spear extends from the nose, which is a new generation of radio antenna system. Below the pilot's cockpit is a huge circular air intake, which is equipped with an integrated air compressor, a gas turbine, an afterburner chamber and a circular tail nozzle.

The second-generation Raptor still attaches importance to weapons and armor protection. It has been replaced with two 30mm caliber machine guns, but the aluminum alloy armor no longer provides comprehensive protection. Instead, based on combat experience since World War II, the armor is mainly in front-front to resist shells fired from the front.

Of course, at this time, the Tang Air Force no longer only developed one type of fighter jet, but divided the fighter jets into different categories according to their combat purposes, and derived Raptor interceptors used to intercept bombers, Raptor attack aircraft used to cover ground combat, etc., and armor protection in different parts is installed according to their uses. For example, the attack aircraft mainly strengthens the belly armor protection.

The Tang Empire was established with high technology, and electronic technology was the most rapid development. The airborne small radar system has been realized and can be installed in the second-generation Raptor fighter, allowing Tang army pilots to discover the enemy first and occupy a favorable position in advance to attack the enemy. It greatly improves the chances of winning the battle.

At the same time, the Raptor second-generation fighter aircraft was also developed, and the supporting devices such as the Tang army's large aircraft carriers were successively replaced with more powerful steam catapults and blocking cables.

The steam catapult used by the Tang army before was towing the two front wheels of the fighter jet. Now the second-generation Tang army aircraft adopts swept wings, with a wheeled layout of one front and two rear, so the catapult has to be replaced with a single slide rail. This has greatly reduced the operation process of the catapult and improved the success rate of the catapult.

However, the carrier-based jet aircraft has a long taxiing distance and is only suitable for the second-generation large aircraft carriers of the Tang army. Only the flight deck length of the second-generation aircraft carrier can the success rate be ensured after assisting the catapult. As a first-generation Tianwang-class aircraft carrier, because it is a straight-through flight deck, the first-generation Raptor is still used as a carrier-based aircraft.

Of course, the Tang army is ready to retire the Tianwang-class aircraft carrier because they firmly believe that the jet fighters on the second-generation aircraft carrier are enough to defeat any country's carrier-based aircraft, because whether it is Germany, the Soviet Union or the United States, their jet fighters are land-based and have a speed of no more than 600 kilometers per hour. The Tang army's second-generation fighters have a minimum speed of more than 800 kilometers per hour. With the strongest 30mm cannon firepower and the most advanced radar system, they have an advantage in combat, and victory is almost certain.

Therefore, the Tang army not only wanted to retire the first-generation aircraft carrier early, but also planned to cancel the escort aircraft carriers, because relying solely on the Tang army's 20 second-generation aircraft carriers was enough to gain an overwhelming sea and air advantage.

However, the Ministry of Defense of Datang was still very cautious and did not agree to the Navy's request, and continued to retain first-generation aircraft carriers and escort aircraft carriers for service.

In addition to the Raptor fighter series, Tang Jun also replaced the jet engine with bombers and reconnaissance aircraft.

Among them, Hellfire II continued to be used. The land-based Hellfire II bomber has added several tons of weight to the head after installing a jet engine. The payload has not changed much and can still carry 1,000 kilograms of aviation bombs. However, the weapon system has changed a lot. There is no close-range fighting machine gun weapon system, but two sets of rocket launchers are installed under the wings, equipped with 12 30mm caliber rockets, which can be used to fight enemies in the air, and can also be used to attack target ships on the ground and at sea.

The second-generation JF-11 bomber, which has been equipped with a jet engine, has greatly increased its power. Although its range has not changed much, its combat radius of 1,500 kilometers, its size has doubled. The fuselage alone weighs 37 tons, the normal take-off weight reaches 72 tons, the normal load capacity reaches 3.5 tons, and the maximum load capacity reaches 9 tons, which has exceeded the Dabaihe strategic bomber.

As a result, the Tang army's definition of bombers also changed. Light bombers stipulate that they can load 3 to 5 tons of bombs, medium bombers can load 5 to 10 tons of bombs, and heavy bombers can load 10 to 30 tons of bombs.
