You need to research information (using the internet) that includes answers for the following questions:
1. How the turning rotor makes a helicopter move upwards
2. How the rotor is made to turn in a helicopter and in an autogyro
3. How autorotation is used to help land a helicopter safely if the engine fails
4. Why a helicopter; falling during autorotation, could reach a terminal speed without the pilot changing any controls
5. The effect of the weight of the helicopter on terminal speed
Over the summer you need to carry out your research in preparation for the controlled assessment you will be completing it for Physics in September. You must make sure that you include:
Relevant information from at least 6 sources
All your sources identified in the text
All information presented clearly and ready to be written up
A full bibliography
Consider the reliability of the sources used
You will be completing your research write up in the first lesson back after the holidays.
You must make sure that you come prepared with your research and full bibliography!
This sheet and the research pack will be available on my blog on the VLE throughout the holidays. If you have any problems then you need to email me to let me know before September!
How Helicopters Fly http://science.howstuffworks.com/transport/flight/modern/helicopter6.htm Imagine that we would like to create a machine that can simply fly straight upward. Let's not even worry about getting back down for the moment -- up is all that matters. If you are going to provide the upward force with a wing, then the wing has to be in motion in order to create lift. Wings create lift by deflecting air downward and benefiting from the equal and opposite reaction that results (see How Airplanes Work for details -- the article contains a complete explanation of how wings produce lift).
A rotary motion is the easiest way to keep a wing continuously moving. You can mount two or more
