Outlet Plastic Air How do you use a European bike pump?
I'm from Australia and bike pumps there have a little flexible cylinder at the end with a screw that you screw onto the wheel's air inlet after which you can the pump up your tyre. Not so in Europe. The bike pump I just bought only has an inlet outlet hole with a detachable plastic nut whose function I can't figure out. In any case none of it seems to fit onto the tyre's air inlet and I cannot for the life of me figure out how it's supposed to work. Am I supposed to buy another part separately? Please help!
I mean Australian bike pumps have an attached nut, not a screw, that you screw onto the tyre's inlet tube.
The pump looks like this:
So, your pump head probably has a lever. Put the tube valve in the pump head. Pull the lever away from the head body to lock the head onto the valve. Pump.
since rocket work on the famous newton principle i suggest that if i get my rocket aerodynamics right. then upload fueal (probably methanol) and ignite the air outlet. will generate thrust.
i'm just a beginner and i suggest this because having carried out very simple experiment using plastic bottle and quick fuel. ignited the improvised air outlet, newtons law was exibited (pls see 7sec vid)http://www.youtube.com/watch?v=YX9PZZwI58E
so if i make a more complex design in agrrement with necessary aerodynamics and load the chamber with enough fuel and ignite. is that all i need for a more complex rocket system.
also if anyoe can give me a detailed layman explanation of how a model rocket works i'll be glad. thanks
Looks as if you have the basic idea(s) down. Now you need to figure out how to get a large enough air supply for more fuel.
Model rockets work just like the big ones. They usually have a solid fuel (which contains its own oxygen) and they still work on Newtons Laws.
