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.

Posted on by blogger

Businesses are increasingly being held accountable by consumers for their impact on the environment. Governments are also mandating reductions in carbon emissions and will likely continue to enforce new environmental regulations on businesses. Consumers are choosing “green” companies more than ever. Email, SMS and Voice communication solutions enable your business to significantly reduce the carbon footprint of your day to day communications. Through the use of highly automated electronic delivery mediums you can reduce your impact on the environment and increase your overall communication effectiveness.

The facts

A recent study conducted by the International Telecommunications Union has shown that switching from direct mail to an electronic communication method such as voice, SMS or email reduces CO2 emissions by a staggering 98.5%.

Reduce waste and increase ROI

Electronic delivery means no tree logging, no paper waste and substantially reduced carbon emissions required for delivery. The automated nature of broadcast technology also means a significant reduction in energy costs.

The impact of undelivered and returned mail can be expensive both from a cost and environmental point of view. Consumers are so overwhelmed with the amount of junk mail received, a business is lucky if the consumer even sees their message. With electronic communication delivery, the cost to your bottom line and the environment of unsuccessful communications can be reduced to zero.

Moving to a green solution doesn’t mean you have to compromise on the success of your campaign. Switching from direct mail to electronic delivery can actually increase the return on investment for your campaign. Response rates to SMS, email and voice campaigns regularly exceed direct mail campaigns.

In addition to the direct savings to be made by switching to electronic delivery, there are indirect savings such as mitigation of staffing costs associated with mail merging and physical sorting, reduced wear and tear on printing equipment and zero costs for franking and returned mail handling.

The greenest paper is no paper

– Completely paperless technology means zero tree logging
– Zero physical waste
– Zero carbon emissions related to delivery (postal vs. electronic delivery)
– Zero cost for undeliverable mail
– Positive “green” brand recognition
– Increased ROI
– 98.5% reduction in overall carbon emissions

The bottom line is simple – demonstrate to your customers your commitment to the environment through the use of environmentally friendly electronic communications solutions.

Electronics Gadgets Hints What Is A Capacitive and Resistive Touch Screen

Posted on by blogger

You may have noticed a spate of gadgets being released recently that do not have any buttons but instead require the user to touch the things they want to interact with on the screen this is called touchscreen technology. But what precisely is touchscreen technology?

A Touch Screen is a device in a form of a display screen that is sensitive to touch and pressure. You can normally use a gadget by a touch of a finger or hand or by using a stylus. It is outfitted with an electronics visual display system which detects the presence of touch along its display range.

It also works as an input tool, where its interface can be modeled to palpable buttons. A touch screen can be used as a keyboard and its recent multi touch technology allows the touch screen to recognize handwritings and finger actions. It also recognizes graphics by plain touch on the screen.

electronics gadgets which are digital in nature makes use of the touch screen technology. It is normally used for ATM machines, sale terminals in the grocery or department stores, mobile phones, video games and PDAs or the personal digital assistant. Touch screens are graciously functional in hospital monitors which check on the progress of a patient, satellite navigation gadgets like a car navigation devices and for industrial usage like control panels. Touch screens became enormously popular since 2007 when Apple introduced iPhone and the iPad in 2010.

Kinds of Touch Screen technology

* The resistive touch screen technology has functioning layers made up of electrically metallic conductive and resistive sheets which gathers voltage from back to front to permit the controller to compute the user’s needs. This type of touch screen is affordable and resists dust and water, but it can be damaged by sharp items which come to contact.

* The surface wave touch screen technology on the other hand applies ultrasonic waves on the screen panel. This in turn sends the information required to process the user’s activities. This is the most advance technology available for a touch screen.

* The capacitive touch screen technology is layered and stores electrical charges. Upon the user’s touch, it is immediately transmitted for the processing of the information. It can only use fingers to harness the screen unlike the resistive and surface wave technologies which can make use of both fingers and stylus for navigation.

When buying touch screens, it is important to take note of the following:

* It should have features which you can easily use, like the ability for changing characters should you use it as a keyboard or as a mobile phone.

* The clarity of the display resolution is another important attribute.

* It should have a capable battery life and fast charging for you to fully utilize and make the most out of your gadget.

* It should be dirt, water and heat resistant, which makes cleaning very minimal.

* It should come with a warranty for repairs or change of parts.

With this helpful facts in mind, it won’t be hard to find your ideal electronics gadgets with touch screen features. Good luck on your touch screen hunting!

How Long Does It Take To Play Jazz Guitar

Posted on by blogger

Jazz guitar is quite an absorbing and secretive technique of guitar live to many rock and realm guitar players decide to take part in as a way of broadening their musical horizons and civilizing their improvisational skills.

Quite often a rock or realm guitarist working in the studios all daylight hours will be found live jazz guitar in the clubs turn over three in the morning; it’s a way in support of these working guitarist’s to ‘let it all hang out’ and stretch themselves so they can keep a fresh handle to their guitar live.

Unlike mainly other styles of guitar live jazz guitar requires the player to possess quite a trace of hypothetical and technical skills under their belt or else they dive in.

Here’s an overview and a realistic age frame so you can frozen up your own jazz guitar encode.

Jazz guitar techniques

* alternate alternative

* arpeggios

* rope bends

* hammer-on’s

* pull-off’s

* slides

* vibrato

Most importantly, the guitarist requisite effort on live a steady flood of eighth clarification on top of the vocal background of standard jazz tunes this practice is referred to as ‘melodic continuity’.

Essential jazz guitar scales

* minor pentatonic

* blues

* major pentatonic

* modes – Aeolian & Dorian

* major diatonic

* vocal minor

Listening to complete jazz players is a necessary part of learning jazz guitar; a partial tilt would include: Charlie Christian; Django Reinhardt: Herb Ellis; Barney Kessel; Howard Roberts and George Benson.

Jazz rhythm guitar: Is a art! To take part in a mild rhythm guitar in a jazz come together the player needs to be able to take part in chords in their triadic and scaletone seventh forms all on top of the fretboard in all major.

The same as well as being able to take part in kick off voicing inversions of scaletone seventh chords, three annotation chords and occasionally even two annotation chords.

Jazz chord progressions:

The mainly communal chord progressions in jazz are the 2-5-1 and the 1-6-2-5 progressions; again it is necessary to the guitarist learns these progressions in all major.

Equipment:

Guitars: A mild quality semi-acoustic emotional guitar is ideal in support of live jazz; you don’t possess to turn obtainable and accept a Gibson ES-175 or L-5 a mild Yamaha or Aria semi-acoustic guitar will execute the job entirely fine. The mainly chief fixation is to take note to how the guitar ‘sings’ lacking the amplifier; take note carefully to the

Guitar’s sustain and tone lacking the electronics.

String gauge: A rope gauge of.011-.052 is the industry standard in support of jazz, if you are live a jazz guitar with a vaguely shorter level e.G., a George Benson GB-10 you will stumble on a rope gauge of.013-.056 will be ideal.

String brand: I possess tried all the major brands and possess found D’Addario to be a very unfailing and steadfast brand of strings; you might aim to try out with discrete types of rope windings e.G., even wounds are complete in support of chord solo effort there’s additionally half-wound strings and the standard in a circle wound rope.

Amplifiers: ‘Acoustic Image’ be selected for complete portable jazz amps to you can take with individual worker and will fit without difficulty on the back seat of several car. If you are fortunate sufficient to stumble on either a used PolyTone or Roland Cube amps check them obtainable both are beautiful amps to possess a very musical sound.

Basically, after you are retail a jazz amp the priority is the amp’s capacity to produce accurately the sound of your guitar confidently highlighting your guitar’s acoustic qualities; usually 60 to 100 watts is all the power you need in support of jazz.
