The project I chose to do was hovercrafts. Hovercrafts are a mode of transport which is not very popular yet but, I think they are extremely interesting.
The basic components of a hovercraft are:
• The skirt
• The platform
• The fan
• The rudder
The skirt is a piece of material which is attached to the platform. There are small holes underneath the skirt which allows air to come out and creates a platform of air for the craft to rest on. The platform is the main base of a hovercraft. This is where people are and where you can control the craft from. The fan provides thrust and inflation for the craft and skirt. The air comes out of the fan and is directed by the rudder to control which direction the craft goes in. Air is also sucked up through the fan and is contained and eventually escapes the skirt. The skirt has low air pressure because the air does not have a lot of time to build up in the skirt. If it did then the skirt would eventually burst.
My aim for the project was to create a working hovercraft model and an information board about hovercrafts.
There were many ways in which I could have approached this topic. I could have contacted a hovercraft manufacturing company and see if they could help me with my research into how hovercrafts work and my model design. I could have also contacted a hovercraft captain and see if he could help me with understanding hovercrafts and my model. I also could have found any engineer and see if he/she could help me understand how the mechanics and engineering part of a hovercraft work. I could have even gone on a hovercraft myself and witnessed how hovercrafts worked.
I decided that I would use the internet for my research into hovercrafts. The internet is forever expanding an...

X. To prevent the material between the vent holes from ripping, you can use duct tape to reinforce the holes.
XI. Flip the hovercraft over so the plastic sheet is now on the bottom.
XII. Place the leaf blower into the hole that was cut for it on the top of the hovercraft and turn it on. You may need to lift the wood off the ground slightly to let the air flow into the plastic skirt.
XIII. Seal the hole around the blower with duct tape if too much air is escaping.
XIV. To test the hovercraft, place it on a smooth, flat surface, in an area with surrounding walls or fencing.
XV. The hovercraft will lift up and start gliding around.
XVI. Have an adult help you as you manoeuvre the hovercraft. Carefully sit on the hovercraft. When you are safely on, turn the leaf blower on.
XVII. Test out your hovercraft's speed and manoeuvrability.

The history of flying dates back as early as the fifteenth century. A Renaissance man named Leonardo da Vinci introduced a flying machine known as the ornithopter. Da Vinci proposed the idea of a machine that had bird like flying capabilities. Today no ornithopters exist due to the restrictions of humans, and that the ornithopters just aren’t practical. During the eighteenth century a philosopher named Sir George Cayley had practical ideas of modern aircraft. Cayley never really designed any workable aircraft, but had many incredible ideas such as lift, thrust, and rigid wings to provide for lift. In the late nineteenth century the progress of aircraft picks up. Several designers such as Henson and Langley, both paved the way for the early 1900’s aircraft design. Two of the most important people in history of flight were the Wright Brothers. The Wright Brothers were given the nickname the “fathers of the heavier than air flying machine” for their numerous flights at their estate in Kitty Hawk, North Carolina. Orville and Wilbur Wright created a motor-powered biplane in which they established incredible feats of the time. The Wright Brothers perfected their design of the heavier than air flying ma...
You are going to want to pull the book directly out of the freezer and remove the wax paper wrapped around it or pull it out of its Ziplock bag and lay it flat on your counter. Then, turn your blow dryer onto the hottest and highest setting. Take your blow dryer and move it around the cover of your book, working across the entire surface so that your cover becomes dry. As it dries, open the cover and continue to apply hot area to the cover.
(Moore). The player must develop a technique called circular breathing where he or she inhales through the nose, stores air in their cheeks, and exhales through their mouth without stopping the air flow through the horn.
As the air-fuel mixture is burned, the gases expand so that the pressure is increased further. Part of this energy is captured by the turbine blades and translated into the rotation of the compressor shaft, and thereby supplying the energy the compressor needs to function.
Hot air is taken into the chamber assembly from the remainder of the house through the come duct, affected by the blower across the evaporator to cool down, then pumped-up back to the remainder of the house through your home's duct system.

My project has to do with robotic arms for amputees and ways I could help improve them. I chose this topic because I have always been interested in the human body and medical innovations. Now I really did not know much about prosthetic limbs or robotics, but it did interest me greatly, so I was willing to learn.
In mythology Daedalus was an inventor who used a set of wax and feather wings that he created to help him and his son escape from imprisonment on the island of Crete. In 1988 students from Massachusetts Institute of Technology let this idea of manpowered flight inspire them to create a bicycle-type plane made of carbon fiber and ingenuity. The students’ plane took flight in April 1988 and set the record for the longest human-powered flight, by flying for four hours in near 123 mph winds. This success story inspired NASA to create a partnership with the MIT students and in 1989 John Langford, the manager of the Daedalus project, started Aurora. This company now specialises in making high altitude UAVs, unmanned aerial vehicles, for the military and to monitor climate change (source 2).
The solution to all these would be to install window coverings like blinds, awnings and shutters for your home. These tools not only improve ventilation in hot weather and conserve heat during cold weather, but they also provide privacy and security for you and your family.

2.3 Components of Hovercraft :- The hovercraft is the most significant component of the project. The design of this component is documented in the remaining sections of this report.
I made a cube like structure out of Popsicle sticks that was nice and firm. I cut out the corner of the Ziploc bag and tied it to some string and tied the string to the Popsicle sticks. I took more Popsicle sticks and made edges to hold up the cube. I made my finally touches by making the parachute and putting it on the cube. The parachute was made of a Walmart bag that I cut the handles off of and tied some string to it. I rapped the string around the four sides of the Popsicle sticks. I took
I have been interested in airplanes since my childhood. The first airplane I built was a paper fold plane during my school days. Though it was built for fun, I also used to compete among my friends. The planes flying for more distance or staying longer in air were declared as the winners in those competitions. To win in the competition, we used to build planes of various designs and tweak them to fly for longer distance or to stay more time in air. Though it was done unknowingly, today I can relate them with resp...
... projects. These projects have left me with a deep impression of how the real world situation is going to be like. Hence, I feel fortunate to have taken this module.
