Shadow Spy

Chapter 181 Modification Design and Site Selection

In his previous life, Li Junhao once saw a saying on the Internet: The appearance of the F6F "Hellcat" is as always brick-shaped. It has insufficient speed, maneuverability, and climb rate, so it uses an engine to make up for it!The designer's point of view is very clear. As long as the power is strong enough, bricks can fly into the sky!

This is indeed the case. After the F6F "Hellcat" was replaced with the HP R-2800-10W-18-cylinder air-cooled radial engine, the power was increased from the original 4-cylinder 14 horsepower of the F1200F "Hellcat" to 2200 horsepower; the flight speed It increased to 629 kilometers per hour, the climb rate was 13 meters per second, and the firepower was also increased from four 4mm heavy machine guns to six. However, the body also increased a lot, with a fuselage length of 12.7 meters, a wingspan of 6 meters, and a significant increase in fuel. , but even so, its range actually reaches an astonishing 10.24 kilometers.

You know, the maximum take-off weight of the F6F has reached 6990 kilograms. Now he has replaced this engine with the F3247A-2, which has a maximum take-off weight of only 2 kilograms. That speed... well, the airframe cannot adapt!

It just so happens that the barrel-shaped fuselage of the F2A is too ugly, so change the fuselage!
The F6F's fuselage design continued Grumman's ugly style. It was still a barrel, which he didn't like. Only the F8F "Panda" at the end of World War II had a better-looking fuselage, with a preliminary smooth shape and only an increased wingspan. It’s more than one meter and the length of the aircraft is increased by half a meter, so use it!
The reason why he did not use the original HP R-8-2800W two-speed supercharged air-cooled radial engine of the F30F was because its performance was not improved much, it only increased the torque and used a large engine with a diameter of 3.84 meters. The efficiency of the 4-blade propeller has not improved much, but it consumes more fuel. This also brings a series of new problems, such as: because the propeller is too large, the main landing gear must be lengthened to prevent the propeller tip from touching the ground; The space occupied by the wing landing gear compartment also needs to be designed to be folded separately, which is a lot of trouble.

As for other aspects, Li Junhao decided to use the F8F-1N night combat Panda as the modification blueprint, and made some corresponding adjustments. Although these are only based on his imagination and understanding, he believes it makes sense.

In addition, he applied the super aluminum alloy developed by Little Japan and the high-strength nickel alloy steel from the Czech arsenal to the body, which not only increased the structure of the body, but also greatly reduced the weight, and the effect was good.

After a night of tossing, Li Junhao finally determined the modification plan and built an F8F-LJH model with his own personal characteristics, which passed the software-simulated wind tunnel test, take-off and landing test, high-altitude test, shooting test, etc. After many adjustments, the optimal effect was achieved.

What he needs now is a place where he can actually take out the modified aircraft and test-fly it.

On Wednesday, July 7, as soon as he got to work, Li Junhao walked around the police station, announced his return, and then went back to the office to catch up on his sleep.

In the afternoon, he went around No. 527 Haiphong Road and learned about the situation of the first batch of 1400 patrol officers undergoing rotation training.Overall, it looks good. Most people don't want to lose their jobs. Of course, there are a handful of people whose performance is really bad enough. They have been blacklisted by the instructors because they have not repented after being reprimanded many times.

In this regard, Li Junhao was more direct. With a stroke of his pen, these guys were all fired and executed immediately!He doesn't have time to rely on these old fritters. Time is precious now.

Then, accompanied by his old acquaintance Major Luke, commander of the first battalion of the Fourth Marine and Land Regiment, he went to inspect the No. 1226 Xinzha Road No. 256 Xinzha Road headquarters of the No. 196 Squadron, the No. [-] No. [-] Xiaoshadu Road No. [-] Xiao Shadu Road headquarters of the No. [-] Squadron and the No. [-] No. [-] Squadron subordinate to the Fourth Regiment. The location is No. [-] Xiaoshadu Road.Major Luke was a little puzzled by his behavior. He didn't know what he wanted to see?
When leaving the military camp, Li Junhao felt a little regretful. He wanted to see if there was enough space in the three military camps to build a temporary runway. It didn't need to be too long, just 200 meters. Then he could take off and land on it. airplane; but alas, there is no space for this.While riding back in the car, he suddenly remembered the next place - the racecourse!There was plenty of room for his plane to take off and land!So he immediately asked Nick, who was driving, to divert to the racecourse on Jing'an Temple Road...
-
The racecourse was built in 1863 (the second year of Tongzhi in the Qing Dynasty), covering an area of ​​500 acres, with stands on all sides, and a 1.25-mile (2012.25m), 60-foot-wide (6.096m) horse racing track that surrounds the venue; in the middle of the racetrack there is 430 acres of land was purchased by the Shanghai-Hai Sports Fund Board of Directors to build a comprehensive stadium, also known as the "Xiqiao Public Stadium", which includes a golf course, baseball field, football field, cricket field, bowling green, and tennis courts. Stadium, etc., and in 1892 (the 18th year of the reign of Emperor Guangxu of the Qing Dynasty), the first swimming pool in Shanghai was built.

Although the racecourse and Xiqiao Public Stadium are located on the same land, they are managed by different organizations.The Horse Racing Association manages the outer track and grandstand facilities, while the stadium and inner track in the middle are managed by the Sports Foundation.

On horse racing days, public stadiums are closed; on non-race racing days, public stadiums are open all day.

In addition to various sports competitions, Western overseas Chinese communities hold major celebrations or military parades and drills, and they often rent public stadiums.

At that time, the racecourse was known as the best racecourse in the Far East. However, in 1909 (the first year of Xuantong in the Qing Dynasty), Chinese were allowed to buy tickets to watch horse racing and gamble, but the stands were separate from Westerners; and as a public sports facility, However, Chinese people are never allowed to enter the stadium.The largest sports facility in East Asia was built on Chinese soil, but had no connection with the Chinese. This was a true reflection of the social conditions of that era.

Upon learning that the Commissioner of Police had arrived, the manager of the Racing Club hurriedly came out to greet him. Unexpectedly, the young Commissioner just wanted to enter the racecourse to take a look!
After an inspection, Li Junhao felt very satisfied. It was enough to turn this site into a small airport. For propeller aircraft at this time, a straight runway of 200 meters long and more than ten meters wide was enough to take off and land. In terms of lines, no fewer than ten tracks can be drawn in just the middle area of ​​the horse racing track!

As for the ground being covered with grass, it is not a problem at all. Propeller aircraft are not that proud. However, in order not to damage the ground and make take-off and landing more efficient, it is best to find a way to install a hard runway. He has this. An idea that should work.

Li Junhao felt that it was a waste to keep the racecourse in the hands of those British businessmen. They had made enough money over the years!Rather than letting these stupid guys cling to it and be confiscated by the Japanese after the outbreak of the Pacific War more than two years later, he might as well do it first and use this place to do something useful!
