Chapter 127： Engineer Level 5, Target Rotorcraft

The work of replacing the power generation method in the shelter went very smoothly. Although the current coal output is still low, it is only used as fuel after all, so the output of a mine is more than enough.

As for the other effects of coal, Ankai can't do many of them at present, he is still limited by the level after all.

However, this predicament finally ceased to be his limitation on the third day after Kent and the others left.

[Engineer level 5, the highest level engineer, can manufacture all kinds of high-tech equipment, can make all kinds of vehicles, including but not limited to: rotorcraft, helicopters, cars, trucks, large motorcycles, yachts, ships. Unlock some modern weapons. 】

This is a text prompt for engineer level 5, and the content can be said to be very simple. After all, engineer level is originally used to provide preconditions for other skills, and this skill itself is not complicated.

And the wisdom of the master plan has also been promoted to the limit by him. At present, he can save 70% of the materials and increase the production speed by 70%, and the things he has manufactured can guarantee 4 products.

As for the stable production of the 5th product, related skills are still needed. For example, a rank 5 weapon requires a full-level arsenal skill. For example, a level 5 tool requires a full-level blacksmith skill.

At present, the stable output of Grade 5 can be guaranteed mainly by some simple equipment weapons, as well as those vehicles in the skill description of level 5 engineers. Sacrifice like sacrifice

Yachts and ships currently made by Ankai are of little significance. Of course, it is not completely meaningless. He can actually open up a road to the river and build a suggested pier. Then he can use to build inland watercraft to transport the river to Use it. But he doesn't have so much material now, so he can only think about it.

Cars are not the best choice in today's environment.

In fact, if there is enough fuel, it is best to make an airplane.

Of course, water transportation is also very good. When Ankai prepares to wait for enough materials, he will directly do both.

Aircraft are used for detection, and ships are used to transport items.

As far as the aircraft is concerned, this is really too useful. In today's environment, there may be threats from zombies on land, and there is no such concern in the air.

But how to put it, there must be a problem.

The fact that aircraft cannot be used for transportation is the most troublesome.

But this question has to be separated into two parts.

If it is a helicopter, it can naturally be responsible for part of the transportation function, but the materials required by the helicopter are too scary, and the fuel consumption is huge, and the movement is not small.

In fact, when it comes to flying alone, the rotorcraft is the best choice at the moment.

Compared with helicopters, the advantages of rotorcraft are really too big in today's environment.

There is almost no difference in appearance between the two. They both have a large-diameter top rotor, which relies on the rotation of the rotor to generate lift during flight.

But apart from these superficial consistency, the rotorcraft and the helicopter are almost two completely different aircraft.

Rotorcraft is actually an aircraft between a helicopter and an airplane. In addition to the rotor, it also has a pair of vertically placed propellers to provide forward power. Generally, it is also equipped with a smaller wing to provide part of the flight. Lift. The biggest difference between a rotorcraft and a helicopter is that the rotor of the rotorcraft is not connected to the engine transmission system. The engine does not drive the rotor to provide lift for the rotorcraft, but during the flight of the rotorcraft, the front airflow blows the rotor to rotate to generate lift. Like a windmill, the rotor system is only driven by its own power when starting, which is called pre-rotation, and is driven by air force after takeoff.

The helicopter's rotor is connected to the engine drive system, which can not only generate lift, but also provide power for flight, like an electric fan. Diminish

Because the rotor is self-rotating, the torque transmitted to the fuselage is very small, so the rotorcraft does not need a tail rotor like a single-rotor helicopter, but it is generally equipped with a tail to control the flight.

In flight, the most obvious difference between the rotorcraft and the helicopter is that the rotor of the helicopter is tilted forward, while the rotor of the rotorcraft is tilted backward.

In addition, when some rotorcraft take off, the rotor can also be connected to the engine through a "clutch", and the engine drives the rotation to generate lifting force. This can shorten the take-off and run distance, and climb almost steeply, but it can't ascend vertically, nor can it hover in the air.

When a rotorcraft is flying, the lift is mainly generated by the rotor, and the fixed wing only provides part of the lift. Some rotorcraft do not even have a fixed wing, and all the lift is generated by the rotor.

Since the rotor of the rotorcraft is driven by the rotorcraft to move forward, if the engine is parked in the air, the propeller will not rotate, at this time the rotorcraft will continue to fly forward because of its inertia, and gradually reduce the speed due to gravity and air resistance. At the same time as the height drops, there is a bottom-up relative airflow, and the rotor can rotate to provide lift. In this way, the Xuanji plane can glide and land safely with the pilot's control. Even in the special circumstances where the pilot cannot control and the rotorcraft loses control, it will land like a parachute. Although it is also a rough landing, there will be no situation similar to the landing on the top of the scale.

This provides a lot of safety for the rotorcraft, which is completely incomparable to a helicopter.

Although the helicopter also has the ability to safely land on the lower edge of its rotation, its rotation needs to transition from a powered state to a self-rotating state, and this transition requires a certain height loss. If the flight altitude is not enough, then the helicopter may not have time to transition and touch the ground. The rotorcraft itself flies in the state of autorotation and does not need to be transitioned, so there is no such height restriction required for safe conversion But the rotorcraft does not have the powerful engine power of a helicopter. , So it can hardly carry any cargo function. The self-weight of the rotorcraft plus the weight of the pilot has basically occupied the full load capacity of the rotorcraft. Of course, different types of rotorcraft are different in this respect. A slightly larger rotorcraft can more or less still have the ability to lose weight.

All in all, the rotorcraft is a very good addition to the current shelter.

Although it cannot be used for transportation and can only be used for simple investigations, this is actually very important.

After all, An Kai currently regards the guys behind the zombie mutation as his main enemies, so he needs to observe where these guys exist. At present, it can be determined that the city they are in is one of the strongholds of those guys, otherwise it is impossible to have three mutated large zombies appear, but where these people are hiding and whether there are in other cities, these are unknown. Mi He Mi

If you drive a car to investigate, it will not only be easy to be discovered by the other party, but if the other party sends more powerful zombies out to pursue it, it will be difficult for the person in charge of the investigation to escape.

But with the rotorcraft, this problem does not exist. Moreover, the rotorcraft is only a general term for a class of aircraft. It is not completely impossible to add a power system. Adding a certain power system can transform a single-person rotorcraft into a two-person ride. The extra person can use both hands to use weapons. It also guarantees a certain attack capability.

So after he was promoted to Engineer Level 5, An Kai was thinking about being able to squeeze a gyroplane. He didn't even consider whether the people in his shelter would drive this thing.
