Bright Sword Military System

Five helicopters were assembled in Liyuan, the model is VS300.

Speaking of this model, Wang Xuexin believes that Ying Jiang originally wanted to give it to the early model... There are several models of VS300 according to the level of safety and advanced.

The original was the VS300 type 39, this helicopter can be said to be a prototype, and its first flight was successful in [-]... But this "success" cannot be said to be successful, because it only achieved hovering but could not move forward, and then it was in the subsequent experiment A sudden gust of wind blows the boat down and crashes it. This event is called a "sudden wind and roll" event.

Then there was the first flight of the VS40 II in 300 years, which realized the hovering and advancing of the helicopter.

In 41, VS300 developed to the third type. This type has realized most of the functions, and the code name was changed to VS300A.

At the end of the same year, the VS300 developed into Type IV, which should be said to be an improved type. On the basis of Type III, it changed the nose into a streamlined shape that is more suitable for flying, and added a hydraulic damper system to improve the performance of the helicopter. greatly improved.

Afterwards, because Ying Jiang participated in the war, all funds were concentrated on the research and development of aircraft carriers and carrier-based aircraft, and the development and improvement of helicopters basically stopped.

Ying Jiang originally wanted to give Wang Xuexin VS300 Model [-], which is the model before improvement.

Ying Jiang thinks this way: Anyway, helicopters are Ying Jiang's military secrets, and others don't even know how far Ying Jiang's helicopter has developed, so who would know if the relatively backward third type was given in the transaction?

But this idea was quickly shattered by Wang Xuexin's few words.

"Sun Erwei!" Wang Xuexin said: "We bought this helicopter mainly for combat. Although you have helicopters, if your helicopters cannot satisfy me or have no practical significance, then..."

"I know!" Sun Erwei replied: "If you can't meet your requirements, then you have no reason to buy!"

Wang Xuexin nodded, and then asked to tell Yingjiang this sentence.

There is a reason for Wang Xuexin to do this, in order to prevent Yingjiang from shoddying backward models for trading.

Yingjiang thought it over and over again, and finally decided to hand over the latest model, the Type 300 VS[-], to the Eighth Route Army.

The reason is very simple. Although the Type III VS300 can barely meet the flight requirements, it cannot be used in actual combat... Because this thing is not equipped with hydraulic dampers, the entire fuselage will vibrate violently with the rotation of the propeller like a tractor during flight.

This situation will inevitably lead to many helicopter failures, difficult operation, and pilot fatigue, especially the inaccurate shooting after adding weapons.

And Wang Xuexin also said that they would cancel the deal if they couldn't actually fight... In order to avoid side effects, let's use the most advanced four-type deal, at least they have shown sincerity!
Therefore, Wang Xuexin was relieved when he saw the hydraulic damper system in the delivered parts.

He knew that although this was not the most advanced helicopter, it was already Eagle Sauce's most advanced helicopter.

The assembly of this helicopter is very simple, it is like a combined bed purchased online, install the brackets according to the drawings and do some welding if necessary, the most important part is to install the engine and arrange the oil pipes inside , circuit, and adjust the control system, and finally put a skin on the nose... This VS300 helicopter has no skin on the tail, and the steel frame is exposed outside.

The flight instructor was a major named Alberta.

The reason why an instructor has such a high military rank is because this Alberta is a member of the helicopter research and development team... Before that, the Yingjiang military did not train helicopter pilots because they did not pay attention to the development of helicopters, so they could fly helicopters Only the researchers of the R&D team, they even learn while groping.

"Comrade Commander!" Alberta handed the information to Wang Xuexin, and reported: "This is our most advanced VS300 four-type helicopter, which uses an upgraded 4AC-199 engine and can provide a power output of 100 horsepower!"

These are not what Wang Xuexin cares about. He took the file and looked at the data: the maximum speed is 128 kilometers per hour, and the maximum range is about 500 kilometers...

The reason why the maximum range is "approximately" is that if its full load capacity is used to load fuel, it can theoretically support a flight of 500 kilometers, but the actual flight time is only 1 hour and 32 minutes.

(Note: This flight time was a world record at the time)

After all, it is scientific researchers rather than professional pilots who fly the helicopters. It is not easy for them to persist for such a long time in a state of high tension that may threaten their lives at any time.

In addition, it is unrealistic to use all the loads of helicopters for fuel. Some loads must be freed up for installation of self-defense weapons or shipment of supplies. Otherwise, what is the use of helicopters being able to fly?

Wang Xuexin continued to look down at the data: the ceiling is about 3000 meters.

The reason for using "approximately" is because no one dares to fly up again... The helicopter is a new gadget, and its flight is unstable, and no one dares to test its ceiling.

The 200-kilometer voyage has a load of 500 kg.

Looking at the data, Wang Xuexin couldn't help frowning. The helicopter with this performance is not said to be useful, it is barely enough for the Eighth Route Army, or it can be said that it is useful without a helicopter, but such performance obviously cannot meet the needs of the Eighth Route Army. Practical needs.

One of the biggest issues is speed and payload.

The maximum flight speed is only 128 kilometers per hour, which means that it can only fly 128 kilometers per hour. If it needs to carry 500 kilograms, the range is only 200 kilometers.

It is about 100 kilometers from Datong to Taihang Mountain, and it is 200 kilometers one way and one way. This does not include the fuel consumption of hovering in the air and combat.

In the northeast direction, the straight-line distance from Zhangjiakou to the north is more than 300 kilometers just to reach CF City, that is, to walk through the Yanshan Mountains, let alone continue north to Daxinganling.

The load is only 500 kg, and if calculated on the basis of 80 kg for an adult, it can accommodate almost six people.

How much ammunition and supplies can this load carry?
Seeing Wang Xuexin's expression, Alberta asked nervously, "Comrade leader, do you have any thoughts on VS300?"

"Its performance seems to be much worse than Hans' helicopter!" Wang Xuexin said: "I heard that Hans' helicopter can lift 75MM anti-tank guns, and its weight is obviously more than 500 kilograms!"

"Yes!" Alberta's expression became a little unnatural: "PAK40 anti-tank gun, it weighs about 1500 kilograms!"

"The load is three times different?" Wang Xuexin looked at Alberta suspiciously. Even if there was a gap between Yingjiang's helicopter and Hans's, it shouldn't be so different.

Alberta explained: "Hans uses a Brameron engine with an output of 120 horsepower, while ours only has 100 horsepower, and Hans' helicopter uses two engines, so..."
