Unmanned aerial vehicle for electrical switch monitoring

Daily life production can not be separated from the power supply, power operation is related to everyone's production of each company.

Many power units have begun to use unmanned aerial vehicles to inspect high-voltage transmission lines, which improves the efficiency of inspection.

Substation is also an important part of all kinds of electrical switches.

The normal operation of the electrical switch is also related to the operation of the entire power grid. Manual inspection of electrical switches, the efficiency is too low. FPV battery
The appearance of unmanned aerial vehicle (UAV) can greatly improve the efficiency of inspection, and the installation of thermal infrared imager on the top of the substation can be used to monitor the damage of the electric switch

CLASSIFICATION OF MODEL AIRCRAFT

From my understanding, the aircraft is divided into 2 major categories, such as real model aircraft, as well as non real model aircraft.
Like a real model aircraft, refers to the real aircraft as a reference, to reduce the proportion of aircraft.
Not like a real model aircraft, it is not a reference to the real aircraft, just as the model developed aircraft.
Whether it's a real model plane or a model plane, it can be broken down into smaller classes
Exercise machine / sports machine | high-speed aerobatic machine | glider | machine, racing machine
Exercise machine / exercise machine: exercise machine is generally refers to the pneumatic structure is relatively stable, the speed is low, easy to novice reaction and control models. Sports machine is relatively higher speed, better flexibility, can be used as a training machine.RC HELI LIPO BATTERY

Stunt flying machine: there are many levels and types of stunt flying machines, such as 3A, 3D models, refers to a particular standard match, and meet the performance requirements of the aircraft, are classified as 3A or 3D. We often hear the so-called 3D machine, just a short term, but does not represent the aircraft flying in the 3D space, if you can not fly in the 3D space, can only run on the ground. That's a car or a ship (see below)
Glider: a glider with power and an unpowered glider. The general characteristic is dexterous, leisurely, for the novice to operate a frame powered glider is not difficult, but to make a high level glider or to rely on air control in a glider and requires considerable level.
High speed / racing machine: as the name implies is the pursuit of high-speed aircraft.
For the name and meaning of the model match, see the following description:
Free flight class (class P1)
P1A - traction model glider (P1A-1, P1A-2 two)
P1B - rubber model glider (P1B-1, P1B-2 two)
P1C - piston engine model glider (P1C-1, P1C-2 two)
P1D - indoor model aircraft (sub P1D-1, P1D-2 two)
P1E - electric model aircraft
P1F - rubber model helicopter
P1S - hand model glider (divided into blank time and distance)
P1T - ejection model glider
Two, line control class (class P2)
P2B - line manipulation stunt model aircraft (points P2B-1, P2B-2, P2B_3 three)
P2C - line control team racing model aircraft
P2D - line operated air combat model aircraft
P2E - line control electric stunt model aircraft (P2E-1, P2E-2 two)
P2X - wire controlled rubber model aircraft
Three, radio remote control (class P3)
P3A - radio remote control stunt model aircraft (sub P3A-1, P3A-2 two)
P3B - radio remote control model glider (sub P3B-1, P3B-2 two)
P3E - radio remote control electric model aircraft P3K

AIRPLANE

Completely from the design of an aircraft, is a system engineering, involving many professional work, including the overall aerodynamic, structure, strength, flight control, avionics, control, hydraulic, fuel, electrical and other professional work together for many years, to design a decent aircraft test process aircraft design to do a variety of front to back are: wind tunnel test, whether it is designed by the aerodynamic shape, or reverse engineering the aerodynamic shape to the process, to do the wind at low speed and high speed wind tunnel test. Static test and fatigue test of aircraft, mainly used to verify the rationality of design, the need to complete the aircraft manufacturing, static test to destroy aircraft, aircraft static strength test, fatigue test machine dedicated to verify fatigue performance of aircraft. The second is the function of the test system, each subsystem to verify the functions, on the ground, a system is a system to do the test, such as engine switch, hydraulic system leakage etc., a 737 similar aircraft to go through the function test about 150 or so, can finally first flight. Don't worry, this is not the end, it is proved that the aircraft can fly, if you want to sell aircraft, also need a lot of flight, flying out of various limit state of the aircraft, draw the flight envelope, and verify whether the design meets the aircraft airworthiness standards. Usually this stage to many years, ARJ21 aircraft from 2008 to complete the first flight, by the end of 2014 was finally completed all flight test subjects, got the airworthiness certificate, which also set the national strength. How hard it is to get a plane, I've been a very streamlined project, there are countless R & D experiments, etc.. Model aircraft in the design of the aircraft in the eyes of people, is a toy, there is no reference. If you design a real airplane, you need to start from scratch. RC HELI LIPO BATTERY

where to buy aircraft

If you have a model shop around you, then you had better go shopping, and then brag with the

boss. Now the developed Internet can provide you with all the information you need when you buy a

plane, but the face to face communication with the magic, the effect should be better.

But you should

be careful, in reality there are many profiteers, they love blackmail your hard-earned money, and

don't care about you is not able to go smoothly. If you encounter such a businessman, he sold you the

right thing, rather than the most expensive thing, then, when you blow up the machine, you will go

back to his shopping, so the experience is relatively happy.

Online shopping is another good choice for you. Through the network at any time to pay attention

to the reference information, so that you will not make too much mistake. Again, you must be careful,

we know that the network is a minefield. A better choice should be a reputable shop (Translator: all

foreign famous model shop, it is recommended that you choose the domestic online shop, communication,

logistics and other more convenient), such as Red Rocket Hobbies, RCPlanet, HobbyPeople, eHobbies,Tower, Hobbies, Hobby, Lobby etc.. FPV battery

Of course, foreign Ebay, a treasure on the domestic also have a lot of good things. You may meet

something you've never heard of, just because it looks cheap". If in doubt, then you should ask the

people around, to find a forum, look at the video on YouTube (see, want the wall). In short, you need

to be careful about what you want to buy and who you buy.

RC HELI BATTERY

Before flying and a set of professional buddy attempts to design a plane, then settle a matter by leaving it unsettled. Find a lot of problems. For example, the controller, I can do a small aircraft flying stability of the autopilot, but the problem is that the transmission of pure telex or hydraulic cylinder? How should the hydraulic system be done on such a light plane? Is there a suitable hydraulic cylinder? Whether can guarantee stability. If there is no conflict between the material and the material of the aircraft, the design assembly adjustment cycle is too long. Cost is too high. The matching of power system and the dynamic attribute need a large amount of data. Aerodynamic simulation of what is not too much of a problem, and then on the metal fatigue simulation of what the heart is not at all. It's more about experience and money RC Heli Battery

spare parts

Debugging and testing, which is an important part of the model aircraft, because the aircraft itself is a model of the dishes. So do a good job of psychological preparation, when you learn to fly, sooner or later, is to blow up the machine, and it is likely to be “early”, rather than “late””.

If there are ready-made accessories, “repair” will be very convenient. When you are shopping for your first plane, you should take a moment to see if there are spare parts. Certain brands, such as HobbyZone and ParkZone, will provide everything you need.

Generally speaking, RTF aircraft accessories than bulk aircraft accessories cheaper. FPV battery

If you don’t have spare spare parts when you buy a model aircraft, your aircraft will have a lot of security and performance problems in the face of the possibility of maintenance

DESIGN OF MODEL AIRPLANE

1, design thinking. Large aircraft and small aircraft design ideas are not the same, not to mention the aircraft and model aircraft. Because of the simple structure light weight, model did not consider the physical constraints limit the structural strength and the overload of the model only can be in a certain range of flight is good, but the real aircraft design must consider many factors, each kind of design scheme is the influence of various factors on the balance.

2, power aspects. Aircraft flight speed doubled, the engine power will become 8 times the original, the aircraft flight speed, the greater the thrust requirements. Now the aero engine thrust weight ratio increase is really very difficult, so to make full use of the thrust of the engine, and other components must lift the flap aileron is very well designed to generate enough lift. But due to the power of the model aircraft, there is no concern in this regard. This is why many models can fly out of the real aircraft can not do strange action.

3, structural strength. Due to the size effect, the aircraft needs to optimize the structural design, so as to meet the strength requirements as far as possible to reduce the quality of the structure. There is a saying that "in order to reduce the quality of each gram of struggle", but the model does not need to worry so much, many times with the framework of foam, plastic or wood structure can meet the requirements.

4, control aspects. Model aircraft are generally controlled by the ground, direct remote control servo motor can control the flight control of the rudder. The model aircraft in flight by the less interference, so simple to control. However, when the aircraft is flying, the air flow is complicated, and the feedback torque is large. To deal with the complex flight conditions, people can not rely on the plane, the aircraft has a complex power system and control agencies, and even the ability to automatically control the autonomous flight, which is not the model aircraft. RC Heli Battery

5, security aspects. The model is low cost and no one, so occasionally some small failure is acceptable, it is inevitable. But the high cost of the aircraft, but also related to human life, while the risk of flight speed is large, it is necessary to minimize the risk as much as possible. The plane of the key parts of many institutions have more than one, there is a safety margin, a bad one immediately involved in the work to ensure flight safety, it is not a model can be forced landing and recovery, but the aircraft can not easily crash. These are some of my views, it is not comprehensive, because the aircraft design is a large systematic project, many professionals need to design a few years to complete. As the fuel system and the economy of these I do not mention, because it really is can be seen but have little talent and less learning, and to make the design of the aircraft model aircraft designers, it is hard too hard too hard too hard too hard too hard too hard too XD

Hand or fly to fly

The degree of completion of your first plane was entirely up to you.

Even the family bought the aircraft model, assembling aircraft also involves a plane from a pile of parts in all aspects. You may have a great sense of accomplishment, but you also need a lot of knowledge and skills. You’ll have to buy your own motor, battery, battery, remote control, etc..

We do not recommend that you use a traditional light wood coach to make your first aircraft. You should learn to fly and enjoy the fun before you take the risk of blowing up your hard work.

If you buy a set of Ready (Almost to Fly, that is, quasi hand flying) remote control aircraft, then 90% of the things have been completed in the ARF. All you need to do is to buy motors, batteries, batteries and remote control. At this time, you also need to master some model knowledge, but the production is not so difficult.

If you are learning to fly at the same time, you want to intervene in the field of model aircraft production, then the ARF suite will be a good way to get started. 75C FPV lipo packs

If you want to fly the aircraft as soon as possible, then buy a set of RTF (Ready To Fly, that is, “flying”) will be the best choice. RTF electronic equipment on the plane (motor and receiver) has been fully installed. In addition to some of the basic assembly work (such as installing the wing to the fuselage), all you need to do is to recharge the battery, install the transmitter battery and fly.

In recent years, all kinds of foam material in electric RTF aircraft has attracted many people to go. They are affordable, convenient use, provides a shortcut to the devil. To deal with a pile of foam, the “worst” maintenance is also playing with all kinds of glue.

how many flights do you need?

This is a very important question. Once again, the good or bad of the aircraft will determine how much fun you can get from the model plane.

Simple “park fly” type electric aircraft (Parkfly, is very popular, not for the purpose of the game, for the public model aircraft), usually two or three, for self-study, they are more commonly used. There is also a single pass remote control aircraft, but they are more like toys than models

To experience the real result of fun, generally speaking, should be more than three, because there are many limitations of the two aircraft.

Conventional two – way aircraft generally control the rudder and motor speed, which can control the speed of the aircraft to climb and glide. Three – way aircraft generally control the rudder, elevator and motor, or the other way is to control the aileron, lift and motor. For beginners, it is more common to control the steering wheel. Aileron control is even more important for stunts because they need to be controlled to provide a smooth roll. FPV battery

Of course, no one can stop you from using E-flite four 15E, such as the Apperntice trainer. Such a remote control aircraft is a bit difficult for self-study, but in the end you will benefit more.

A four remote control aircraft can control the throttle, aileron, rudder and elevator. The aileron channel, to some extent, increased the difficulty of learning to fly, because of the need for better coordination of action. That’s why it’s not as easy to use as a three pass.

Here, we will use the three remote control aircraft (with motor, lifting and direction control), HobbyZone super Cub LP such models (the above with dihedral on the monoplane) as the entry-level model.

HOW HARD IS IT TO MAKE A MODEL ENGINEER BUILD A REAL AIRCRAFT THAT CAN FLY?

Compared to the traditional aircraft designers and high performance UAV designers, a model

aircraft designers generally lack the following capabilities: first, structural design. For the model

aircraft, especially the sports machine, a lot of time can take a very rude way to design the

structure. It is a common practice to use a heavy, heavy plate in a place where there is no need to

use some glue to fix some structures. Of course, the purpose of this is to reduce the cost or reduce

the complexity of the process, as well as special reinforcement in some places to withstand rough

landing (because the model may not be good enough to manipulate the technology). But for the use of

the value of the aircraft, it is very bad to do so. And the general model structure efficiency is not

high, so in fact can not carry any load. Of course, the model may be in addition to a set of FPV

equipment is also nothing to bring god. But for the practical value of the aircraft is not the same.

And aeroelastic problems on the general model is not considered, but the big guy, this is a headache

thing. RC HELI LIPO BATTERY
Process and material is also a problem. Basically the model designer in the design to take into

account the material is wood or composite glass fiber and carbon fiber. But for metal materials, is

about a question three do not know. How to design a semi monocoque metal body? How to make aluminum

sheet metal? How to rivet? How is the metal beam connected to the fuselage? How to strengthen the

openings? Oh, let's talk about world peace. In the compound is also. The model manufacturers for

composites is not very high, so you want to let them make clear what what what the glue with carbon

fiber, what size autoclave temperature much much pressure, they will only give you about working at

the master, and then let him feel to. Even the wood, the model designer may not be proficient.

Because of the small size and weight, that is, the material properties of wood are not fully

developed. Again, the design of the aerodynamic shape of the idea will be very different. In any

case, it is in the worst of the aircraft will not appear on the aircraft trainer head of this crude

to outrageous shape.
