Liu Kui is very appreciative and optimistic about the "wild helicopter" summoned back by this group of Zerg brood.

Liu Kui swore with confidence: "With these, it will not be far from me dominating the world!" ”

The Zerg Mother's Hive was very happy when she saw Liu Kui's confident appearance at this moment.

So he didn't say anything more and directly gave Liu Kui some information about the helicopter.

Because these "wild helicopters" summoned by himself have many similarities with current helicopters, it is more appropriate to let Liu Kui understand about helicopters. Only by understanding the helicopter, Liu Kui will be able to have a greater probability of getting along with these "wild helicopters" in the future. Of course, these helicopter-like robots will better serve Liu Kui and exert their tremendous power.

Liu Kui seemed to be in a good mood, and couldn't wait to open the book about the common sense and basic knowledge of helicopters handed to him by the Zerg Mother Hive, and let him take a good look.

Liu Kui knew that his level was poor, so he was still more serious when he read the book.

"There are many forms of helicopter mechanisms, and the body structure of conventional helicopters includes fuselage, rotor system, tail rotor, mechanical control system and landing gear.

The fuselage is used to support and fix helicopter components, systems, connect them as a whole, and is used to carry personnel, materials and equipment to make the helicopter meet the established technical requirements. The fuselage is an important part of the helicopter.

The shape of the fuselage has a significant impact on the flight performance, maneuverability and stability of the helicopter.

In the process of use, the body bears not only the load from various loads, but also the dynamic load from moving parts, weapon launches and cargo lifting. These loads are transmitted through the joints. In order to load and unload cargo and install equipment, many doors and openings are designed in the fuselage, which complicates the structure of the fuselage.

The alternating load transmitted to the fuselage by the rotor and tail rotor causes the vibration of the fuselage structure, affecting the comfort of the occupants and the fatigue life of the structure. Therefore, when designing the fuselage structure, measures must be taken to reduce the vibration level of the helicopter fuselage.

The propeller is an important component that provides lift, and the design of the propeller requires not only aerodynamic requirements, but also dynamic and fatigue requirements. For example, the natural frequency of the designed propeller does not resonate with the aerodynamic excitation force, and the fundamental frequency of the propeller swinging and oscillation meets the requirements of maneuvering stability and "ground resonance". The load-bearing structure of the propeller can have high fatigue performance or adopt a breakage safety design, etc. The development of rotor blades is based on materials, processes and rotor theory. According to the order of development of the propeller, it has three forms: hybrid impeller, metal propeller and composite propeller. Due to the fact that the hybrid blades were gradually replaced by new ones in the late 50s, they are currently only used on heavy helicopters Mi-6 and Mi-26.

The rotor system consists of a blade and a hub. The rotor form is determined by the propeller form. It has evolved with the development of materials, processes, and rotor theory. So far, the rotor forms that have been applied in practice are articulated, seesaw, unhinged and bearingless.

The tail rotor is the component used to balance the reverse torque and maneuver the course of the helicopter. The rotating tail rotor acts as a vertical stabilizer and stabilizes the helicopter's course. Although the function of the rear rotor is different from that of the rotor, they are both aerodynamic forces generated by rotation and work in asymmetrical air flow when flying forward, so the tail rotor structure has many similarities with the rotor structure.

Generally, the load of the shaft is large, the use conditions are complex, and the balance vibration characteristics and the reliability of the shaft are high. Any damage to the propeller shaft of the helicopter during flight can force the flight mission to be interrupted at least and cause serious accidents at worst. Therefore, the transmission shaft of modern helicopters requires long-term bench tests, fatigue tests and flight verification tests to obtain comprehensive use data such as life and reliability.

The main role of the landing gear helicopter landing gear is to absorb the energy brought by the vertical velocity during landing, reduce the overload caused by the impact during landing, and ensure that "ground resonance" does not occur during the whole use. In addition, the landing gear is often used to give the helicopter the ability to move on the ground, reducing the impact and turbulence caused by uneven ground when taxiing.

Helicopter landing gear used on land includes wheeled landing gear and skid landing gear. If the helicopter is required to have the ability to take off and land on the water or make an emergency landing, it is generally required to have a water-sealed fuselage and a pontoon to ensure the stability of the lateral side, or an emergency forced landing pontoon. For carrier-based helicopters, it is also necessary to equip special landing devices, such as pull-down equipment.

The control system is used to control the flight attitude and flight direction of the helicopter, which can be divided into three parts, namely the friend variable distance system (used to control the helicopter to take off), the foot control system (used to control the tail slurry to rotate the helicopter), and the joystick control system is used to control the direction of the rotor pull).

In the mechanical control system of a helicopter, the automatic tilter is the most important component. The auto-tilter, also known as the auto-tilter, is used to manipulate the rotor to achieve lifting, forward-backward, and side-to-side movements.

Auto-tilterThe auto-tilter is a major component of the helicopter control system, through which the total distance of the rotor and the periodic variable pitch control are realized. ”

Liu Kui casually read a few chapters and had a preliminary understanding of helicopters.

Liu Kui tried to communicate with the theoretical knowledge in the book and the "wild helicopter".

Sure enough, as Liu Kui expected, it would be much easier to communicate with these aliens summoned by the Zerg Mother's Hive in this way.

Liu Kui felt that this was very strange, so he endured it again and again, and finally couldn't help but ask the Zerg Hive: "Why do I use the method of maintaining the helicopter to try to communicate with this group of helicopter aliens you summoned but think it will be very effective?" What is the reason for this, do you know it? ”

When the Zerg Mother's Hive heard Liu Kui ask herself, she didn't know what to do.

It's not very good to not be able to answer Liu Kui's question, so the Zerg Brood Intelligence replied simply and generally: "Just communicate with this group of wild helicopters I summoned according to the method of repairing helicopters!" In this way, we can cultivate very awesome characters! ”

Liu Kui was so amused by the Zerg Mother's Hive that he didn't know what to do.

So he asked again, "You didn't make it clear!" Your answer in such a general way is that you don't know it yourself, and you are afraid that it will be embarrassing to say that you don't know in front of others as the head of a school, so you can only ......"

Zhan Xiaogui and his son at this time will make an appointment to go to a place where there are no wires and few people, which will be a good opportunity.
