Hello again, howrang bajaj

Your Question is impossible to answer, because it is improperly asked.

Refer to my earlier answers, also the one I gave you a few minutes ago: http://cr4.globalspec.com/thread/25323/magnets

If you continue asking Questions similar in format to these last four of your Questions, all asked within a few short minutes of time, you may well find that Readers will refuse to give you any replies at all.

I am advising you of this, so that you may learn, and perhaps not ask such Questions in the future.

Kind Regards....

• What is the diameter of the fan?
• Is it shrouded or is it free?
• How many blades?
• What is the pitch of the blades?
• What is the shape of the blades?
• How is it powered?
• How much does it weigh in itself, including motive unit and fuel/power source?
• What is the local air pressure and temperature?

Please help the forum to post helpful replies.

There is an article on hovercraft in Wikipedia on this subject, which may be helpful.

Better model aircraft stores stock model hovercraft, which may prove valuable for personal experimentation locally.

1- Not the fan but the air flow will lift your mass

2- Do you consider the fan static or in the lifted object?

3- If the fan is on the lifted object you have to induce an air flow so that its impulse force is at least = 10 N.

4- If the fan is static then you should generate a flow such that at the distance of 1m the dynamic force of it on the surface of the lifted object will exceed the above mentioned force. The power requirements in this case will be higher.

As you see your question is not complete and shows that you did not think yet about what you want. It would be better to complete your idea and give more input. It would be even better if you look first in a book or use internet to gather informations and formulate your questions only when you do not understand a specific aspect.

I presume that you think about toys (your other question) but for your information there are already such toys. They did not find a large acceptance due to the very short time of use on the battery pack carried on board.
