When Yan Yuqiu blushed and led the two to the airport, Yu Lei, chief of staff of the Air Force, Zhu Binhou, commander of the Naval Aviation, and Feng Ru, who resigned as the designer of the Meteor Company and became the director of the Aviation Procurement Department of the Ministry of National Defense, surrounded Yang Qiu and said something. Two Y-3 (Albatross 1927) military transport planes have begun to turn their propellers, one after the other.

After seeing the two of them, Yang Qiu didn't speak, pointed to the plane behind him, and took the three of them to board the first plane first.

This is a hard and fast rule, prohibiting more than three senior officials and officers from flying on the same plane, so the two of them have no choice but to get into the second plane. But when I went in, I found that there were already several people sitting in the plane, even Leng Jie was inside.

"Where is this going?" Yue Peng asked the pilot.

The pilot immediately saluted when he saw Yue Peng, but he didn't say anything, only said: "Chief of Staff, sit down, it's about to take off." ”

Yue Peng was a little puzzled, where did he go to keep even his chief of the general staff secret? However, he didn't ask much, just sat down and continued to chat with everyone. The plane began to slowly glide towards the runway, and soon the first transport plane climbed into the sky, and after Yue Peng's plane also went to the sky, four Falcon fighters chased up from the left side, protecting the flight on both sides.

Leng Jie and other young people who took a plane for the first time were very curious, and they also waved to the pilots outside from time to time, and the atmosphere gradually became lively. Yue Peng is still a little confused, although he doesn't know how to fly, he can still vaguely feel that the plane is flying north again, is it going to Chengdu?

On another transport plane, Feng Ru and the other three were reporting to Yang Qiu about the aircraft bidding. He also took out the report and photos for him to see.

The brief skirmish in Afghanistan two years ago gave the IDF its first test of ground-air coordination tactics and the importance of aircraft. Since then, the Ministry of National Defense has begun to solicit bids from the whole country for nearly 10 types of aircraft, including trainers, fighters, bombers, transport planes and seaplanes.

China and the United States are different. Even if the low altitude has been opened, the promotion of agricultural aircraft and aviation clubs is very slow, and although the development of postal and air transport is not slow, this supernumerary force cannot support the needs of future pilots, so Yang Qiu has formulated a detailed plan to expand the number of sea and air pilots. According to the plan, at least 20,000 pilots will be kept in the domestic frontline, and at least 50,000 people will receive aviation training in the next 10 years through militia training and other methods to help them obtain junior flight certificates.

Because of this policy, the amount of procurement in this tender is very large. The biplane trainer aircraft with the greatest demand alone is as high as 6,318, and the total purchase scale of all aircraft will reach more than 15,000 aircraft. Of course, this is not a one-year purchase, but the entire purchase amount for the next five years. In addition to the three major aircraft manufacturing companies, many small aircraft factories such as Chengdu's Sikorsky Company also joined the competition, coming up with more than 40 plans and verification machines in total.

"This is the list of those who made it to the second round of test flights. This is a trainer. Feng Ru sat beside Yang Qiu. This historical aviation pioneer was forbidden by Yang Qiu to test fly in person, and after seeing Wang Zhu and others' profound aviation skills, he quit his job five years ago and went to Southwest University to study aviation. After graduation, he did not return to Meteor Company, but was hired by the Ministry of Defense as an aviation technical consultant, responsible for bidding procurement and technical guidance.

The report he gave to Yang Qiu was the company and the aircraft that had entered the second round of testing. Judging by the report, after two years of experiments and tests. Integrating hundreds of technologies for data machines, the three major aircraft manufacturers of Meteor, Airbus and Raytheon are still strong, and it is a bit surprising that the company of Sikorsky, a former Russian designer who has become a Chinese citizen, has been successfully shortlisted in the seaplane.

If the first round is an audition, then the second round of testing is actually the final test flight and improvement of a single aircraft before it is finalized. Therefore, the aircraft listed in the report are basically already the models that have been looked at and will be ordered after all the experiments are completed.

On the trainer plane, Raytheon defeated Meteor and finally won. The White Stork two-seater biplane trainer modeled after the Y-5 is the most suspenseless, and its abilities such as handling, low speed, hovering, and rolling are among the best in the world even if they are put into the world.

But the data and photos of the latter planes made Yang Qiu secretly scratch his head.

The requirements for this procurement of the Ministry of Defense are very detailed and demanding. For example, the bomber must be able to fly directly from Guangzhou to Natuna (2,200 km) without refueling, with a maximum bomb load of 3,000 kg, a range of 1,200 km with a 1-ton bomb, two 1,200-kg large bombs at the same time, a secondary fuel tank, at least four self-defense machine guns, and so on.

Not to mention anything else, the request for a direct flight from Guangzhou to Natuna alone made many small companies completely desperate, and finally entered the second round with only two left, Meteor and Airbus. The former Air Force gave the number H-5, but this H-5 looks very much like the famous JU88 from the photos, but the range is larger, and it should be sacrificed in structure and protection. Using Meteor's own air-cooled Comet 900 engine, a single unit can reach 960 horsepower, a maximum level flight speed of 430 kilometers, and a maximum bomb load of 2,900 kilograms.

After the successful development of Airbus's twin Mustangs, the Meteor company led by Wang Zhu also began to study similar double-layer structure air-cooled piston engines, and after several years of hard work, they finally came up with a comet engine with comparable technology, not only using mechanical supercharging and double spark plugs and other technologies, but also developed the technology that can directly inject methane into the cylinder in an emergency. The most important thing is that the company strictly follows Yang Qiu's requirements, and ensures that the engine interface and the same model of the double Mustang can be used in common while innovating, and even some parts can be interchanged.

That's a huge step forward! This means that although the two factories are highly competitive and each has its own know-how in terms of engines, they have carved the concept of standardization into every aspect of R&D and production.

Airbus' number is H-6, compared with the oldest Meteor company in China, Yang Qiu deliberately used a large number of drawings and technology to pull up the catalytic company, not only finally successfully developed the double Mustang engine, but also has strong technology in the monoplane metal aircraft, and KC-1 has become a world famous brand. Yang Qiuyuan thought that they would come up with a bomber similar to the American B-18, because the B-18 was improved from the DC-2. And DC-2 is now KC-1. But when he saw the photo, he was a little dumbfounded, because the shape of the bomber taken out by Zhou Houkun was very similar to the French "Leore and Olivier LEO451" bomber in the parallel world. For the first time, the H-type lift double vertical tail design was used in a domestic aircraft.

Because the 1200 horsepower engine is still being tested, the H-6 also uses a 960-horsepower double Mustang 2 engine, and the maximum speed is not as good as the H-5 only 400 kilometers, but the range has increased to 2500 kilometers because of the H-type lift double vertical tail, and the maximum bomb load is 2800 kg. And Meteor, like the company, also left room for larger engines to be installed in the future at the beginning of the design.

"Judging from the first round of experiments, the range basically meets the requirements, but the load and speed are slightly insufficient. But both the Meteor and Airbus 1200-horsepower engines began to be tested. It will be ready for production as soon as the end of next year, when performance will improve a lot. As for the models of the 4-engine heavy bomber, none of them are very ideal, and considering the lack of technology, we have discussed and prepared, and we are ready to postpone the tender for the 4-engine heavy bomber for several years. Yu Lei is the chief of staff of the Air Force, and the "Yu Lei Turn" named after him has left him famous in history. He was also the first bomber pilot in China, and he led his troops to kick off the sniper battle at the Battle of Raineyvale. After so many years of painstaking research after the war, and after the test of Afghanistan, he has become a leading figure in domestic air supremacy theory and bombing science. Known as the father of Air Force bombing.

But when the father of bombing introduced the new plane with high interest, he didn't notice Yang Qiu's strange face. The aerodynamic shape of Germany and France, the American engine, and the internal structure of Chinese designers have become a mess, and I don't know what kind of road China's aviation industry will take in the future.

There is a "multinational version" of the bomber at the bottom in the front, and after Zhu Binhou introduced the sea and air fighters, Yang Qiu was no longer surprised, even if the two shortlisted models were so familiar.

The first is a single-engine fighter named after the "snake" in the Classic of Mountains and Seas. The technical performance and figures are similar to the famous British Hurricane, using 800 horsepower Hanyang 12-cylinder Kunlun water-cooled engines, installed with four 12.7 mm aviation machine guns, the maximum level flight speed reaches 450 kilometers, and the range is 800 kilometers.

The second one is from Meteor Corporation. Also named after the mythical "Mighty Wind", while its data is replaced with 4 machine guns for 12.7 mm. The rest is about the same as the early 960-horsepower Japanese Zero A6M1 fighter.

Hurricanes and Zero Battles.

Yang Qiu pinched the tip of his nose, the former is not bad, although it is not the best, it is the best maintainability in World War II, and it is also the easiest aircraft for novices to master, these two points alone are enough! But forget the latter, there are still a few days before 1931 at the moment, and the war is even longer, so these two models are strong enough under the current situation, and they will naturally improve when they find problems in the future, even if they adjust their thinking in a few years.

Thinking of this, Yang Qiu suppressed the words that came to his lips, and looked at the planes behind.

The dive bomber entered the second round for final testing and modification of the Meteor company's "ghost car" dive bomber, which used the same Comet 900 engine as the "Forceful" fighter, considering that the Navy would also procure it. It is different from the well-known dive bombers, and it is not like the JU87 Stuka with unretractable wheels, but adopts a rear three-point retractable wheel, using a Meteor 900 engine, equipped with a dive speed brake and automatic pull-up device, and can carry a maximum of 500 kg bomb.

There was no tender for the torpedo machine this time, and the performance of the biplane torpedo machine used by the Navy at present is sufficient, and the output is not large, so there is no need to reequip it so quickly. As for the last "Fei Lian" seaplane, it is completely the American Caterina PBY1 of the later generations, because Sikorsky is the chief designer of this aircraft, but now he himself has settled in Chengdu, so it is not surprising that it appeared in China.

Yang Qiu, the transport plane behind, only glanced at it a few times, in addition to the plane starting to land, it was also because the engine technology was not enough. But even with all the problems, the report is promising. As long as the engines are up, the planes on the report will be able to reach or even surpass the level of their respective imitation "predecessors", and a powerful and modern air force has finally begun to emerge after 20 years of hard work.

When Yang Qiu returned the aviation report to Feng Ru, Yue Peng and the others had already landed and drilled out of the plane in advance, and when a 100-meter-high barrage dam appeared in front of them, everyone was stunned.

This is where it is
