This Heli-Max Axe CX Micro Helicopter is an example of a model for micro-enterprises coaxial. Note the size comparison with the cell phone right.
Radio Controlled helicopters (also RC helicopters) are model aircraft that are distinct from RC airplanes because of differences in construction, aerodynamics and flight training. Several models RC helicopters are based, some more than others handy (such as helicopter collective pitch). The drawings are often more manageable more difficult to fly, but benefit from greater aerobatic capabilities.
Flight controls allow pilots to control the collective and throttle (Usually linked together), the cyclic controls (pitch and roll), and the tail rotor (yaw). Controlling these in unison with the helicopter can perform most maneuvers of an airplane can do, and that many aircraft can not, like hovering and backward flight, this way, they are quite similar in the operation of helicopters size.
The controls of the helicopter are affected different by servo-motors of small size. A piezoelectric gyroscope is typically used on the tail rotor (yaw) control to fight against the movement wind and tail reaction torque induced. This "gyro" does not apply mechanical force, but rather, electronically adjusts the signal command to the tail rotor servo.
The engines used are usually fed with methanol two-stroke engines, but gasoline, turbine jet and more brushless electric motors combined with high performance battery lithium polymer are used.

Nitro helicopters are currently more common than electric helicopters. Practical electric helicopters are a phenomenon relatively new and rapidly developing and becoming more frequent. helicopter gas turbines are also increasingly popular, although the cost high puts them beyond the reach of most people.
Nitro
Nitro helicopters come in different sizes: 15, 30, 50, 60 and 90 size. These figures came from the size nitro engine used in different models (0.30 cu in, 0.50 cu in and so on). The larger and more powerful the engine, over the main rotor blade that can rotate and thus the largest of the plane together. flight times for nitro helicopters is 7-14 minutes typical by engine size and tuning.
Electric
Recent advances in battery technology make electric flying more feasible in terms of flight time. Lithium Polymer (LiPo) batteries are able to provide the current necessary for high-flying high-performance while remaining very lightweight. flight times are typically 4-12 minutes, depending on driving style and capacity of the battery.
In the past electric helicopters have been used inside mainly due to the small size and lack of smoke. Larger electric helicopters suitable for visual flight outdoors and aerobatics are advanced become a reality in recent years and have become very popular. Their quietness has made them very popular for flying sites close to residential areas and in places like Germany where there are strict noise restrictions. Nitro helicopters have also been converted into electrical energy by commercial and home kits.
The smallest remote controlled helicopter production model made (Guinness World Records 2006) is the Picoo Z sold in many toy stores (although this is controlled infrared, not radio), electronic stores and internet stores, costing about $ 30 (? 15). The smaller side is the Mosquito helicopter blade rotating in opposite directions, which is also a battery powered helicopter R / C.
Several models are vying for the title of the smallest non-production helicopter with remote control, including family helicopters Pixelito micro, family Proxflyer, and micro flying robot.
A recent innovation is the coaxial electric helicopters like the aforementioned Mosquito. stability inherent system has in recent years has made it a good candidate for designing models for beginners and / or indoor use. Models of this type, as in the case of a helicopter on a large scale to eliminate a couple of rotation and the control response extremely Quick, both of which are very ...

Aerofortis 25KW Wind Turbine In Operation

Can someone help me wicker idea for my project?

Can anyone give me a good idea for a project? I am a founation degree in wind turbine technology and just started my second last year and this week. we have a project to do throughout hte year right, but im stuck for an idea of what I could base around. our teacher wants us to take a portion of a turbine and build the project cycle, there incorporating elements from previous modules we covered last year. He has given us an example that we use to Arnt. as the design of a yaw control system or look into the development of a lifting system for greater turbine using limited companies. thes eare a few but I want someone who is educated and experienced in the turbine to help me find an original idea for my project that would be good, interesting and fun to work on ... thank you!

Like Paul Gipes books on wind turbines. They can give you some ideas.

Yaw Bearing $68.51 High Quality Content by WIKIPEDIA articles The yaw bearing is the most crucial and cost intensive component of a yaw system found on modern horizontal axis wind turbines. The yaw bearing must cope with enormous static and dynamic loads and moments during the wind turbine operation, and provide smooth rotation characteristics for the orientation of the nacelle under all weather conditions. It has also to be corrosion and wear resistant and extremely long lasting. It should last for the service life of the wind turbine) while being cost effective. Windmills of the 1700s began implementing rotatable nacelles to capture wind coming from different directions. The yaw systems of these primitive windmills were surprisingly similar to the ones on modern wind turbines. The nacelles rotated by means of wind driven yaw drives known as fantails, or by animal power, and were mounted on the windmill towers by means of an axial gliding bearing.

Active Yaw Control $71.7 High Quality Content by WIKIPEDIA articles High Quality Content by WIKIPEDIA articles Active Yaw Control, auch bekannt als Gierregelung, tragt erheblich zu einem dynamischeren Fahrverhalten bei. Es handelt sich um ein intelligentes Antriebssystem, das an der Antriebsachse sitzt. Ein herkommliches Differentialgetriebe ermoglicht Kurvenfahrt, indem es unterschiedliche Drehzahlen der beiden Antriebsrader zulasst. Es ubertragt das Antriebsmoment gleichmassig auf beide Rader. Das bedeutet aber auch, dass das Rad mit der besseren Haftung nur so viel Traktion hat, wie das, das sich auf glattem Untergrund befindet oder bei Kurvenfahrt gering belastet ist Author: Surhone, Lambert M./ Timpledon, Miriam T./ Marseken, Susan F.

Darrieus Wind Turbine $76.47 High Quality Content by WIKIPEDIA articles The Darrieus wind turbine is a type of vertical axis wind turbine used to generate electricity from the energy carried in the wind. The turbine consists of a number of aerofoils usuallybut not always vertically mounted on a rotating shaft or framework. This design of wind turbine was patented by Georges Jean Marie Darrieus, a French aeronautical engineer in 1931. The Darrieus type is theoretically just as efficient as the propeller type if wind speed is constant, but in practice this efficiency is rarely realised due to the physical stresses and limitations imposed by a practical design and wind speed variation. There are also major difficulties in protecting the Darrieus turbine from extreme wind conditions and in making it selfstarting Author: Miller, Frederic P./ Vandome, Agnes F./ McBrewster, John Binding Type: Paperback Number of Pages: 104 Publication Date: 2010/07/01 Language: English Dimensions: 5.98 x 9.01 x 0.24 inches
