Nowadays‚ some electric fans can cause danger to people especially to children. It may cause wounds due to its blades and heat exhaustion. This study is concerned on Dyson Air Multiplier – a bladeless fan. Dyson Air Multiplier is known as the bladeless fan. It is an electric fan in desktop and floor standing models that are set to give smoother airflow and‚ having no exposed rotating blades‚ operating in a safer manner than the conventional bladed fans. This bladeless fan was tested at Dyson Ltd

The rotor is the spinning component that has wheels and blades attached to it. The blade is the component that extracts energy from the steam. There are two basic types of turbine designs. One is called the "impulse" design in which the rotor turns due to the force of steam on the blades. The other is called a "reaction" design‚ and it works on the principle that the rotor derives its rotational force from the steam as it leaves the blades. A single-flow turbine design has steam entering at one end

3.7 Wind Generators: There are three main parts in horizontal axis wind turbines: (1) a rotor‚ (2) an alternator‚ and (3) a tail. The rotor blades are attached to a central hub covered by a nose cone that improves aerodynamics. Three blades are generally present in upwind generators. This entire assembly rotates when wind blows past the blades‚ hence the name “rotor.” In many small wind turbines the rotor is coupled to a shaft which is coupled to an alternator‚ a device that produces AC electricity

Peerless has no way of knowing if the new market will respond as well as the saw blade market did to the anticipated improvements in quality and cycle time coming from the laser. The new product line will require different distribution channels‚ different marketing techniques‚ and will draw new and different competition. Peerless may

entered in the Indian shaving blade market through a joint venture company called ISPL with the House of Poddars. The Malhotras were the market leaders and shrewdly implemented the stock push strategy and thus‚ enjoyed around 80% of the share. The primary product was the carbon steel blade which was very cheap and was of an inferior quality as compared to stainless-steel blades. The other competitor was Wiltech which was facing heavy losses. Gillette believed that blade‚ being a low value product‚

airscrew for propulsion was utilized during the late 1700’s to early 1800’s. Only after experimentation did the inventors conclude that more propulsive power could be obtained by merely straightening out the surface of the airscrew blades. Attempts to utilize the “straight blade” propeller were made by balloonists. These contraptions were quite strange and hardly fulfilled their purpose of actually propelling the balloon. The basic propeller had evolved from the simple concepts of da Vinci‚ and was slowly

results. It was learned that coefficient of power (CP ) for various configurations is different and can be optimized with reference to Tip Speed Ratio. Latest emerging design techniques can be helpful in this optimization. Furthermore‚ flow field around the blade can also be investigated with the help of these design techniques for safe operation. © 2011 Elsevier Ltd. All rights reserved.

This amazing sculpture was created out of Cedar wood‚ where Philip McCracken carved the piece out then added a leather strap and blades along the body. This piece of art is currently on display at the Seattle Art Museum. The “War God” is a wooden sculpture and it was about 2 feet long and about 8 inches wide. The sculpture has lots of jagged edges and cut outs of blades that give it a very fierce look. McCracken chose to sculpt this piece of art because of the environment he was living in. He lived
