Natural Wind Speedometer The best time to fly a kite is when the wind is between  4 and 12 miles-per-hour. If the wind is less, then most kites have problems flying. If the wind is more, then most kites will lose control. So watch the trees, bushes, flags and grass to know when the wind is just right. The other thing to watch for is wind turbulence. Turbulence is what happens when the wind gets bumpy.

Wind turbine design Typical modern wind turbines have diameters of 40 to 90 metres (130 to 300 ft) and are rated between 500 kW and 2 MW. As of 2014 the most powerful turbine, the Vestas V-164, is rated at 8 MW and has a rotor diameter of 164m.ll wind turbines are designed for a maximum wind speed, called the survival speed, above which they will be damaged. The survival speed of commercial wind turbines is in the range of 40 m/s (144 km/h, 89 MPH) to 72 m/s (259 km/h, 161 MPH). The most common survival speed is 60 m/s (216 km/h, 134 MPH).

How To Make A Delta Kite The pictures should make things pretty clear. Just quickly work your way through from top to bottom, skimming over any detail that you don't need. The MBK 1-Skewer Delta kite is quite small at 1.0SL (29cm, 11 1/2) in length, but copies the full-size Deltas with a floating spreader and triangular keel.Speaking of larger Deltas...ow's the time to read up on kite materials and other things needed for building a Delta kite, if you haven't already. The template shown above represents one side of the kite sail. You will now transfer these measurements to the sail plastic as follows...

- by Crash | posted in: Kite Info | 0. A kite is a special sort of aircraft, attached to the ground by a string. When a kite is stopped from being blown backwards, usually by the string we hold in our hand, it will fly. Because this sort of aircraft has no engine, the power to lift the kite is the wind. Without wind moving over the kite it won’t fly. Some kites need lots of wind, others need very little.

- Use only plain thread, better not to use manja for this process. The entire thread should be visible on side 2 (on which the sticks are not visible). Tie the knots tightly so that they won’t move and tear the kite. The final or the third knot is very important – it decides the flight of your kite.

How to fly a kite Flying Space should be a clear, open area. Stay away from roads, power lines or airports. Open fields, parks and beaches are great for flying kites. The more room you have, the more line you can let out. Remember that as the wind goes over and around trees and buildings, it gets bumpy and difficult to fly kites in. Watch out for kite eating trees!

The Delta Kite The Delta is actually a very versatile design that can be altered slightly to suit all wind ranges. For example, a high-wind Delta kite will have its towing point more towards the nose of the kite. This reduces the pull on the flying line, and hence the stresses on the spars.Also, the amount of sail billow can be increased to provide more directional stability.ccording to kite shops, 2 meter (6 feet) wing span Deltas are the most popular. One of the biggest retail designs in 2008 was the Sweet 16 Delta, which has a span of 5 meters (16 feet)! Even that pales in comparison to another kite, a one-off, which was used in altitude record attempts in Canada in 2001.

Wind turbine design A wind turbine is designed to produce power over a range of wind speeds. All wind turbines are designed for a maximum wind speed, called the survival speed, above which they will be damaged. The survival speed of commercial wind turbines is in the range of 40 m/s (144 km/h, 89 MPH) to 72 m/s (259 km/h, 161 MPH).n addition to aerodynamic design of the blades, design of a complete wind power system must also address design of the hub, controls, generator, supporting structure and foundation. Further design questions arise when integrating wind turbines into electrical power grids.

What Is the Fastest Wind Speed Ever Recorded? The fastest wind speed ever recorded comes from a hurricane gust. On April 10, 1996, Tropical Cyclone Olivia (a hurricane) passed by Barrow Island, Australia. The equivalent of a Category 4 hurricane at the time, is 254 mph (408 km/h). U.S. Highest Wind

- A hurricane with 145 km/h (90 mph) winds while stationary would have winds up to 160 km/r (100 mph) on the right side and only 130 km/h (80 mph) on the left side if it began propagating at 16 km/hr (10 mph).

Kite (geometry) Kite (geometry) In Euclidean geometry, a kite is a quadrilateral whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other. In contrast, a parallelogram also has two pairs of equal-length sides, but they are opposite to each other rather than adjacent. Kite quadrilaterals are named for the wind-blown, flying kites, which often have this shape and which are in turn named for a bird.

- Wind velocity is highest in the core of the polar jet stream where speeds can be as high as 300 kilometres per hour. The jet stream core is surrounded by slower moving air that has an average velocity of 130 kilometres per hour in winter and 65 kilometres per hour in summer.

Wind Sustained wind speeds are reported globally at a 10 meters (33 ft) height and are averaged over a 10 minute time frame. The United States reports winds over a 1 minute average for tropical cyclones, and a 2 minute average within weather observations. India typically reports winds over a 3 minute average.

The Origin of Kites The generally accepted wisdom is that the kite was invented in China. However it is also known that people in the South Sea Islands have used kites for fishing since very early times. They would attach bait to the tail of the kite together with a sort of net to catch the fish.

How dangerous is flying in high winds? Captain Thomas says that wind shear may cause a pilot to break off a landing at around 3,000ft: “It’s the right thing to do – put the power on and get up and out of there.” Pilots always have a plan B in mind if the intended approach is not safe or if the airport closes because of high winds.

- distance from vertex of right angle to kite-flyer = 100. height of kite = 173.21 feet (rounded to the nearest hundredth). For this particular triangle, you need to only remember that the hypotenuse is going to be (the square root of 2) times either of the legs of the right angle (for they are both the same length). So to find the length of the other sides, simply divide the length of the hypotenuse by the square root of 2.

(n). Forces Acting to Create Wind This motion can be in any direction, but in most cases the horizontal component of wind flow greatly exceeds the flow that occurs vertically. The speed of wind varies from absolute calm to speeds as high as 380 kilometers per hour (Mt. Washington, New Hampshire, April 12, 1934).

How it works 4 - The ideal wind speed for hot air balloon flights - To provide the best conditions for a safe balloon flight landing the maximum surface wind speed on the day of the balloon ride must not exceed 10 miles an hour.

How to Fly a Kite Of course, you will want to have the wind blowing into the sail, this is what creates lift. You really do not need a lot of wind. Many kites will float on a minimum of a breeze, blowing only a few knots. Some kites can even be flown on no breeze at all. There are even indoor kite flying contests where wind does not play a factor. You can buy a wind gauge, but this is not at all necessary, and a simple wet finger in the air will usually be sufficient. For a rough approximation of wind speed you can use the table to the right.

- There certainly is documentary evidence to suggest that kites were being flown in China as long ago as 200 BC. when a general in the Han dynasty is recorded as having used a kite as an instrument of war, by using it as a method of determining the correct distance to dig a tunnel to enter a palace and end a siege.

- The amount of lift required to cause a kite to rise depends on the overall weight of the kite in comparison to the surface area of its sail(s). One additional force works on a kite to work against lift. The kite presents an amount of frictional resistance to the wind.
