Flybarless Rotor Heads – The Ins And Outs

Posted on by blogger

What was the flybar for anyway? The flybar performs three basic functions stabilization, amplificationof cyclic input, and resistance to pitch up in forward flight.

Stabilization: While hovering a wind gust may try and move (tilt) the main rotor. The flybar will be differently (less) affected, and the linkage system will adjust the pitch on the blades to resist the change.
Amplification of cyclic input: When the swashplate tilts and moves the flybar, aerodynamic forcesimposed by the flybar paddles change the spinning plane of the flybar, and again through a series oflinkages this then changes the pitch on the main rotor blades. This means the servos work less hard toachieve a cyclic input.
Resistance to pitch up in forward flight: In fast forward flight the blade advancing into the airflowcreates more lift than the blade retreating in the airflow. This causes a pitch up motion of the helicopter.The flybar again tries keeping in its own plane of rotation, and through the linkage system adjusts thepitch on the main blades to resist this change.

So the electronic components of the system take over these tasks from the flybarSo why ditch the flybar and change to a flybarless head setup?Flybarless helicopters have arguably better all round aerobatic performance. But they are also great forscale models, aerial photography platforms, etc
Advantages include:

Less rotating mass
Lower drag
Combination of longer flight time and better 3D performance
Less mechanical complexity
Infinitely tunable flight characteristics, including improved stability if desired
Looks cool!

What is required:

The Flybarless Head Itself It is ideal to purchase a custom designed flybarless head for your size of helicopter rather than try and modify an existing setup. There are several reasons for this:

The geometry of the head is important
You are purchasing a product that is known to work

Flybarless Electronics You require a system to take over the role of the flybar. There are two and three axis units on the market. For general flying a two axis unit (meaning you still require your own tail gyro) works very well. For 3D flying there are advantages of three axis units, however the two axis ones still hold their own.A two axis unit essentially contains two heading hold gyros (left/right and fore/aft cyclic). A three axis unit adds a tail rotor gyro also. Much like the way a traditional tail rotor heading hold gyro works, the cyclic gyros have the ability to stabilize the rotor head from wind gusts, etc.It is possible to fly a flybarless helicopter without electronic stabilization. However, the task is much easier with the help of an electronics package. You would not fly your helicopter without a tail gyro, would you?
Servo Selection Fast digital servos are preferable. But again, depending on your flying style,any reasonable servo will allow you to experience the flybarless feel.

In Flight: Flybarless helis can be set up to behave in an almost unlimited number of ways. With a flybar,it was time consuming (and expensive) to try a variety of flybar lengths, different paddles, and flybarweights. With the electronic flybar it is simply a matter of changing some of the programmableparameters in the unit itself and you have a whole new feel to the helicopter.There are some further flight differences with a flybarless heli. The cyclic controls now command acyclic rate from the rotor head. So if the helicopter is on the ground and even a small cyclic command isheld, the cyclic servos may move hard over to try and achieve the commanded cyclic rate. So it isimportant not to add cyclic control until the helicopter has lifted off.Autorotation performance is overall improved, but somewhat of a different technique is required torealize this increase in performance.

Are Anti Smoking Campaigns Ineffective The Most Common Reasons People Keep Smoking

Keep Your Breath Kissably Clean with Electronic Cigarettes

Fresh breath is a concern for just about everyone. We use mouthwash, breath mints, sprays, and gum to keep halitosis at bay, but most people still suffer from it at one time or another. Bad breath can be a real romantic mood killer, so the fight for fresh breath becomes even more vigilant when going on a date. Simply put, while no one wants to be able to smell your last meal, people are often overly sensitive about their breath, especially when going out for the evening. For smokers, fresh breath is often more than a concern; it is a constant battle. Most smokers carry some kind of gum or breath mint with them to disguise the smell of smoke, but they still find that everything around them seems to always smell of smoke. Not only does the odor of cigarettes adhere to your clothes and hair, it soaks into your skin, as well. Only the most physically conscious smokers manage to avoid smelling like smoke all the time. When a smoker has reason to be concerned about their breath, they quickly discover how much of an effort it is to keep it fresh.
Breath and Dating

Another challenge faced by smokers is dating. While there are plenty of people who do not mind the smell of smoke, there are many others who will find it hard to get physically intimate with someone who smells like an ashtray. No one wants to have a good date end badly because of smoker’s breath or give up the possibility of getting to know someone because you disagree about the use of tobacco cigarettes. For smokers playing the dating game, this is always a risk.
It’s Almost Necessary

In fact, bad breath is a very natural function and given the conditions of smoking, it’s unavoidable. When you smoke a tobacco cigarette, the smoke bonds to the cilia in your throat and lungs, and also to your teeth and gums. This is what causes the distinctive yellow stains on many smokers’ teeth, and it can also lead to halitosis. Combined with the breakdown of enzymes in the bloodstream, stomach, and intestines, it is no surprise that smokers have such a hard time keeping their breath kissably clean.
Are There Really Smoking Alternatives?

There are always new bad breath remedies marketed towards smokers, but few of these work well enough to justify the high cost. As even chewing tobacco and nicotine gum can leave an unpleasant aftertaste and odor, the only solution seems to be to quit altogether. Fortunately, for those who can neither give up their cigarettes nor the fight against halitosis, there is a new smoking alternative that is not only safer, but smells better too. Fifty-One electronic cigarettes look a lot like tobacco cigarettes, but they are actually very different. Electronic cigarettes do not require a flame. Though an orange LED simulates the burning ember at the end of a cigarette, there is no actual flame or smoke. This means that electronic cigarettes are safer for both you and those around you. Electronic cigarettes are harmless to other people because there is no smoke or dangerous chemicals involved. In fact, Fifty-One is completely legal to use in England, because the smoking ordinances require flame and smoke to qualify as a cigarette. While many other countries still have tighter smoking policies, most people, once they understand just how different Fifty-One is, will have no trouble making an exception for the product.
Other Advantages of Electronic Cigarettes

As a smoking alternative, these are also much safer for you. Not only does the lack of fire reduce your overall risk for many lung and respiratory problems, but you also won’t be consuming hundreds of dangerous chemicals whenever you inhale. Studies have identified over four hundred active chemicals in tobacco, plus several added by tobacco companies, which include among them several carcinogens. Fifty-One electronic cigarette, on the other hand, contains three chemicals, only one of which has any physical effect upon your body. In addition various levels of nicotine (based on the smoker’s preference), electronic cigarettes are mostly water vapor with some propylene glycol added to color the vapor and make it resemble cigarette smoke. Though this vapor is far safer than tobacco, both for you and those around you, it feels surprisingly familiar when inhaled.

Most smokers will have no trouble getting used to smoke that tastes better and helps calm their hacking cough. Once you find a nicotine cartridge level and flavor you are comfortable with, it may be difficult to go back to tobacco cigarettes, especially considering the monetary and social benefits of switching. After the purchase of a Fifty-One electronic cigarettes starter kit, you will start to save money. Nicotine cartridges are sold in five packs for just under fifteen dollars or three dollars per cartridge. Since each cartridge is the equivalent of approximately thirty cigarettes, this means that one pack of Fifty-One electronic cigarette costs about two dollars. If smoking for two dollars a pack is not enough of a reason to quit smoking tobacco cigarettes, the money that you will save on breath mints and gum might persuade you.

Electronic cigarettes are the perfect solution for health-conscious smokers who want a good smoking alternative. Not only does no smoke mean a safer product, it also means that your fight against bad breath will get easier. Fifty-One electric cigarette smokers do not smell like ashtrays, and their clothes are not dotted with cigarette burns. A neat appearance and pleasant smell make it a lot easier to impress a date. Imagine being able to smoke just about anywhere without worrying about halitosis or the reactions of others. The odorless vapor of electronic cigarettes makes it possible to be a smoker without sacrificing social relationships.
