Let’s know about Solar Power Aircraft.

About Solar-Powered Aircraft

The Solar Powered Aircraft developments Solar one is a British mid- wing, experimental, manned solar-powered aircraft that was designed by David Williams and produced by Solar Aircraft Developments under the direction of Freddie To. On 19 December 1978 it became one of the first solar-powered aircraft.

Development and Design

Freddie To was a member of the Kremer prize committee who started his own project to produce a human-powered aircraft to compete for the prize. Its structure comprised a wooden frame covered with heat- shrunk solar film model aircraft film. The wing was built in 3 sections, a centre section and 2 outer wing panels to simply storage and transport. The wing spar is a laminated spruce girder box- spar design. The tail surfaces are quickly removable for storage. The resulting aircraft at 230 Ib (140kg) proved too, heavy for human-powered flight and so To converted it to solar power.

To recharge the batteries, 750 solar cells 0f 3 inch diameter were installed at a cost of 6,000 billion. At that time solar cells were very expensive. They were the mostly costly part of the aircraft and had to be limited in a capacity to remain within the project budget of 6,000 billion.

The output from the solar cells is not sufficient to sustain flight. Before flight they are used to charge the batteries. The batteries then provide power for takeoff and initial climb. The installed batteries provide for a climb of 8 minutes plus a 2- minute cruise allowance.

Learn About Weather…

What is Weather?

The Weather is important to peoples as it affects their comfort, food, their’safety and easy science experiments for kids. Weather is the daily state of the atmosphere, or air at any place. The weather is more than wind or rain, but also includes so many stunning effects like Rainbow, flashes of lightening and sunset etc. Our lives can be affected by weather as it decides what we wear or what we decide to do?

Why Weather is caused?

Weather is caused by heat from the sun and movement of the air on earth’s surface. All weather happens in the lower layer of earth’s surface. The sun heat warms the air in this layer to a different temperature level at different places. Warm air is light, so it rises, and cold air rushes in beneath to replace it. This movement of air is called wind, which causes change in the weather.

Types of Weather

  • Wind : the natural movement of the air in the form of current of air blowing direction.
  • Climate : the weather conditions prevailing in an area over a long period oftime.
  • Lightning : a flash of light in the sky due to the electrical dischargev between clouds or between a cloud and earth’s surface.
  • Snowfall : the quantity of snow falling within a given area in a given time.
  • Hurricanes : a storm wind with a violent wind is called a tropical cyclone.
  • Tornadoes : a destructive vortex of violently rotating winds having the appearance of a funnel-shaped cloud.
  • Thunderstorms : a storm with thunder and lightning and typically heavy
    rain and hail.
  • Earthquakes : a sudden violent shaking of the ground due to the
    movement within earth crust, causing destruction.
  • Volcanoes : is a mountain from which hot melted rocks, gas, steam, and
    ash from the inside the earths erupts.

Learn about Walkie-Talkie

What is Walkie-Talkie?

A Walkie-talkie is a hand device, two way radio receiver/transmitter. It was developed in the Second World War. Radio engineer Alfred J. Gross worked on the early technology behind the walkie talkie between 1934 and 1941. During the war it was developed by Donald L Hings and engineering teams at Motorola led by Henryk Magnuski.

Typical walkie talkies today are phone sized and have a push to talk button. Discovery toys Walkie talkies are used for various reasons, in the military for amateur radio and for personal use.

Facts about Walkie-Talkie:

  1. They’ve been around for over 100 years.
  2. Two-Way Radios were The First Mobile Communication Devices.
  3. The first walkie talkie was the size of a Backpack.
  4. Two way Radios are used to communicate in space.
  5. Your mobile phone is technically a Two-Way Radio.

Development

The idea of walkie- talkies did not get much interest until the war started in 1939. After a few years the Motorola team had improved them, so that the army could use them. There were also vehicle and tank versions. The British, Germans and Americans all had their own versions.

Motorola also produced the hand-held AM SCR-536 radio during World War II and it was called the “handle talkie” (HT). The terms are often confused today, but the original walkie talkie referred to the back mounted model, while the handie-talkie was the device which could be held entirely in the hand (but had vastly reduced range.)
