Now the situation is very good, the base area of the Eighth Route Army has become so large that it has a military port and a shipyard, and now Duan Yunpeng is already starting to build the Third Arsenal, the Second Aircraft Factory, and the First Shipyard of the Eighth Route Army.

These three factories are all built on the Jiaodong Peninsula, because the location here is very good, and the three factories are close to each other, which is also easy to manage.

In June, Duan Yunpeng received the support of the leaders of the Eighth Route Army and decided to officially start the design and manufacture of the second long-range bomber of the Eighth Route Army, which will also become the most advanced long-range bomber in the world.

The Kunpeng No. 2 long-range bomber is more than twice as large as the No. 1, and its maximum take-off weight has reached sixty-two tons!

You must know that now the Boeing Company of the United States is also developing similar long-range bombers, but the Kunpeng No. 2 long-range bomber designed by Duan Yunpeng this time must surpass the B29 long-range strategic bomber, because it uses more advanced and powerful turboprop engines, each turboprop engine, with an output of 3,000 kilowatts, that is, more than 4,000 horsepower.

And Boeing's planned B29 long-range bomber, it can only rely on a 2,000-horsepower Wright twin-cyclone eighteen-cylinder air-cooled star engine.

Of course, the current B29 long-range bomber is only in the program stage, it is the Model 334 program, this design scheme, in the cockpit and the middle of the fuselage with personnel for airtight pressurization, the formation of front and rear independent pressurized cabins, the pressurized cabins are connected by airtight pipes above the bomb bay, and the crew can reach another airtight cabin through the pipeline.

This is also learned from Duan Yunpeng's Kunpeng No. 1 long-range bomber, which has a wing length of 36 meters, enough fuel, and a range of 7,200 kilometers, and the engine compartment is integrated into the main wing.

The design standard of the US Air Force is 650 kilometers per hour and the range is 8,600 kilometers.

Duan Yunpeng knows very well that in another plane, the B29 long-range bomber, but more than 2,000 have been produced, so now he hopes to use the Kunpeng No. 2 long-range bomber to replace the B29 long-range bomber, after all, it has not yet been officially launched, if the United States Air Force sees that the Kunpeng No. 2 developed by the Eighth Route Army is far more advanced than the B29, they will definitely choose the Kunpeng No. 2.

At that time, it can not only make a lot of money for the Eighth Route Army, but also make the country become dependent on Chinese manufacturing.

Duan Yunpeng knew that the development of the B29 long-range bomber was not very smooth, and in the history of aviation, its second prototype had an engine fire accident during the second test flight, and the test pilot made a forced landing, resulting in the death of the crew members and 20 people on the ground.

At that time, Roosevelt was alarmed, because he was already very anxious and dissatisfied with the delay in the development of the B29.

So now if the US Air Force can directly buy the Chinese-made Kunpeng 2 long-range bomber, they will definitely not want the B29 anymore, at most they will spend a lot of money to buy the Kunpeng 2 technology, and then they will produce it themselves, and then it will be numbered as the B29 long-range bomber, in that case, the whole history will change.

The problem with the B29 long-range bomber lies in the engine, after all, there is an upper limit to the performance of the aviation piston engine, so it has always had the problem of insufficient power.

But now the Kunpeng No. 2 long-range bomber designed by Duan Yunpeng is different, it uses an advanced turboprop engine and full horsepower, so it still has a speed of 800 kilometers per hour and a cruising speed of 700 kilometers per hour when the maximum take-off weight reaches 62 tons.

At such a speed, even the P51 Mustang fighter of the United States Air Force is not as good as it.

After all, the Mustang was one of the fastest fighters in World War II, but its ultimate speed was only 710 kilometers per hour, so the Kunpeng 2 long-range bomber would not be afraid of interception by any fighter jet, because it could get rid of the opponent at a faster speed.

Of course, if it is directly confronted, it does not have to be afraid, because Duan Yunpeng is the Kunpeng No. 2 long-range bomber, equipped with powerful self-defense firepower, that is, four six-barreled 40-mm Gatling guns and four 14.5-mm Gatling guns.

With such a powerful firepower, imagine what fighter can get close to it and effectively attack it.

Therefore, the crew of the Kunpeng-2 long-range bomber also has ten to twelve people, including the pilot and co-pilot, navigator, bombardier, mechanic, wireless telegrapher, radar operator and gunner.

The bombardier is at the very front of the nose, in front of the pilot, with the mechanic, wireless telegraph operator and navigator next to the cockpit.

In the pressurized cabin in the rear section, the gunner and radar operator are located, also under armor protection, and the gunner operates the cannon and cannon by remote control.

There is also a tail gunner in the pressurized cabin at the end of the fuselage, who operates both a Gatling gun and a Gatling gun.

In the belly of the Kunpeng-2 long-range bomber, there are two large box-shaped magazines, each of which can hang six tons of bombs.

The largest bomb can reach a ton, and the power of this aerial bomb is very large, if all of this bomb is hung, one bomb bay can hold six.

Compared with the B29 long-range bomber, the Kunpeng No. 2 long-range bomber has a better aerodynamic shape, which includes its wing, which is obviously more perfect than the B29, not only has more lift, but also has less cruising resistance, and it has a certain sweep angle, which is different from the traditional bomber straight wing.

It is closer to the later Tu-95 Bear strategic bomber, so it looks like a mini version of the Bear bomber.

The Kunpeng 2's fuselage is elongated, with a large wingspan and aspect ratio, including its flat tail and vertical tail, which are different from the semi-circular shape of this era, and it is a wing surface with a swept angle.

The wing of the Kunpeng 2 is a cantilever mid-monoplane, all-metal structure, with a sweep angle of 30 degrees, and a hydraulically operated aileron on the trailing edge of the outer wing, with an adjustment plate on the aileron and a spoiler in front of the aileron.

Moreover, the inner section of the trailing edge of its wing has a large area of backward slit flaps, which can be lowered during take-off and landing, and the lift system is much improved.

All these designs are epoch-making, so Duan Yunpeng fully believes that after the Kunpeng No. 2 long-range bomber comes out, the allies will definitely rush to buy it.

After all, who doesn't want such a powerful long-range bomber.

In addition to strong hardware, Duan Yunpeng also designed a very advanced avionics system for the Kunpeng 2, including a long-range navigation system and a bombing radar.

If you want to bomb the little devils in the future, it will definitely be very easy, because a large number of antiaircraft guns of the little devils are all less than 100 millimeters, and they cannot pose a threat to the Kunpeng No. 2, which is flying at high altitude and dropping bombs, and only more than 100 120-mm antiaircraft guns can threaten.
