Chapter 127 News leaked

When Liu Xiu took off in the Cricket aircraft equipped with a new engine, the first thing he noticed was that he felt a push on his back.

That's right, Liu Xiu felt a strong push on his back when the plane took off. With the throttle at 90%, Liu Xiu actually took off after only rowing less than a hundred meters.

Obviously this also shows the powerful power of the new engine. After all, the original two four-stroke engines need more than 300 meters to make the plane take off!

After Liu Xiu ascended to the sky, he retracted the flaps and immediately began to raise the altitude to a height of one thousand meters. Then he began to test the speed of the aircraft according to Liu Qin's request without letting go of the throttle.

However, Liu Xiu didn't dare to pull the throttle again after a while, because Liu Xiu had already heard the creaking sound of the wooden fuselage.

After that, Liu Xiu took another look at the regular pitot tube obtained from the wreckage of the Jaap-1 fighter plane and found that the speed reached 380 kilometers per hour.

After absorbing Liu Qin's homemade simple pitot tube, Liu Xiu asked the independent group to send over the wreckage of the three Type 1 aircraft in Ping'an County, and then found a still usable pitot tube from the damaged facade. .

Although Liu Xiu carried a parachute when he ascended to the sky this time, Liu Xiu could land safely even if the plane disintegrated in the air, but the most important thing was that Liu Xiu gave up the idea of ​​continuing to accelerate.

That's right, for Liu Xiu's safety, Liu Qin specifically asked the quilt factory, where Li Yunlong was the factory director before, to sew several sets of parachutes and send them here.

And Liu Xiu also tested this parachute, which was made up of several sheets sewn together. Not to mention that the effect was really good. At least when Liu Xiu tied a 100-jin pig and threw it from a 100-meter-high cliff, The pig didn't fall to death, and it didn't even have any broken bones.

It was precisely because of this that Liu Qin dared to let Liu Xiu test the strength limit of the aircraft's fuselage.

After Liu Qin heard Liu Xiu's words, he nodded and said:

Such as rolling in the air, trying to climb at a large angle, snake maneuvers and other actions. Anyway, if the plane falls apart, Liu Xiu still has a parachute to save his life!

"Just now I saw that you took off successfully in only a hundred meters, which was one-third of the previous motorcycle engine. So it can be concluded that the horsepower of our two two-stroke engines should be the same as that of the four-stroke motorcycle engine. Three times, about 70 horsepower! Two units are 140 horsepower, plus your throttle is 90%, so the full horsepower should be more than 150 horsepower!"

After Liu Xiu got off the plane, he said to Liu Qin who was walking over:

"Dad, when I tested the top speed just now, I only reached 380 kilometers per hour when I heard the creaking sound of the wooden fuselage, so I didn't dare to try anymore!"

After flying in the air for almost an hour, Liu Xiu looked at the inaccurate fuel tank gauge, which showed less than half of the fuel, then descended to altitude, then aimed at the asphalt runway, reduced the throttle, lowered the flaps, and landed.

This time, with the help of a parachute as a life support, Liu Xiuye ​​naturally became more courageous and started performing various special performances at a thousand-meter altitude above the arsenal.

Later, at Liu Qin's request, Liu Xiu tested the maximum load of the aircraft. Of course, this was not done by a master, but directly on a sandbag.

After adding sandbags again and again, I found that when the sandbags reached 300 kilograms, it was no longer able to take off. This was of course not because the horsepower of the aircraft engine was not enough, but because the wooden fuselage was not strong enough. When the sandbags were added, the wooden fuselage made a creaking sound again. Therefore, adding Liu Xiu's own weight of 160 kilograms and 80 kilograms, the maximum bearing capacity of the aircraft was only 380 kilograms. Kilogram.

So after testing, the parameters of this aircraft are:

Empty weight: 320 kg Maximum take-off weight approximately: 700 kg

Maximum flight speed approximately: 380 kilometers per hour

However, it can bear a weight of 380 kilograms. Excluding the 80 kilograms of the driver and at least 100 kilograms of fuel, the ammunition that this aircraft can carry is only 200 kilograms.

And this is the fuel carrying amount for a short endurance. You must know that during the ground test, the fuel consumption of this two-stroke engine at maximum throttle reached 50 kilograms per hour.

Therefore, one hundred kilograms of fuel is only enough to drive the aircraft at maximum throttle for one hour.

Of course, the specific fuel consumption and economic cruising speed can only be determined after many flights.

Although the data of this aircraft can be considered excellent compared with the fighters of World War I, compared with the aircraft of World War II, such as Mustang, Zero or Type 1 aircraft, it is still far behind, but the equipment A machine gun, and then some bombs to deal with ground personnel is already a big mistake.

But the choice of machine guns on this plane made Liu Xiu difficult. What Liu Xiu valued most was naturally Deguo's chainsaw machine gun, the MG42 machine gun, but the arsenal did not have the conditions to manufacture these!

Therefore, it is difficult to get the kid's crook-handled light machine gun to make up the numbers. Isn't it a joke to use a thirty-round magazine to shoot at the enemy?

Do we have to let the pilot change the magazine while flying the plane?

Just when Liu Xiu was thinking about what machine gun to install on the aircraft, Director Zhang of the arsenal heard this and immediately said:

"It can be equipped with a Type 24 heavy machine gun! Although this thing is not fed by bullet belts, it is fed by bullet canvas belts! And the bullet belts can also be connected to each other, so you can have as many rounds as you want, as long as the aircraft As long as the carrying capacity is enough!”

After hearing Factory Director Zhang's words, Liu Xiu began to wonder what this Type 24 heavy machine gun was.

Liu Xiu thought for a moment and then remembered that this Type 24 heavy machine gun was actually a self-produced version of the German Maxim heavy machine gun. It is said that tens of thousands of such heavy machine guns were produced.

It uses the same 7.92 type bullet as the Mauser rifle, which can be used with the bullets of the Mauser rifle, and the weight of the gun body is only 20 kilograms.

In addition, the weight of the machine gun rack is 29 kilograms. Of course, once this thing is on the plane, it will not need the machine gun rack. The entire aircraft is its machine gun rack.

And the most important thing is that it uses a canvas bandolier. One canvas bag contains two hundred and fifty rounds, and the canvas bandoliers can be connected, so once this thing goes into the air, you don't need to worry about changing bullets.

Of course, in addition to this, the more important point is that this thing is water-cooled. As long as there is water in the water tank, there is no need to worry about the barrel overheating.

Of course, it is also possible to remove the water-cooling cover of the Maxim machine gun and extend the barrel to use the airflow when the aircraft is flying at high speed for air-cooling and heat dissipation.

However, just when Liu Xiu and Director Zhang were discussing how to install the Maxim machine gun on the aircraft, Yoshio Shinozuka in Taiyuan also received news that the Eighth Route Army's arsenal actually produced an aircraft, and also built an aircraft at the entrance of the arsenal. track.
