I do not understand how propulsion in the vacuum of space normally would work. On earth, when there is movement, such as standing up, you are pushing against the ground with enough force to get up. But in space, there is nothing to push against. So even if there are rockets ejecting burning fuel, the fuel has nothing to push against to move the ship forward. (I also do not mean the effects of gravity on sattilites when I ask this question.) Asked by I Ask the World - Mon Jul 6 23:41:28 2009 - - 5 Answers - 0 Comments A. Standing up is not the same as rocket propulsion. In a rocket engine, there is a continuing controlled explosion of fuel. This explosion expands in all directions. But on one side the force escapes out the opening - the nozzle where we see the fire coming out. On the other side, the explosion is pressing against the thrust plate of the engine. This pressure is greater than any other pressure on the rocket, so the rocket moves away from it. The nozzle of the engine is shaped to accelerate the gases out of the engine chamber as fast as possible in the opposite direction that the rocket is traveling in order to create the lowest possible pressure on the exhaust side of the combustion chamber and the highest relative pressures against the… [cont.] Answered by China Jon - Tue Jul 7 00:01:04 2009 How can I use vectors to find the best propulsion for my hovecraft? Q. I have two factors. I have a leaf blower which needs to be angled correctly on the back of the hovercraft to get the hovercraft's best balance to create less drag and at the same time have the best speed. If there are any other methods that you have that are scientific please tell me. My chemistry teacher told me I could use vectors to solve this. Please answer. there are two blowers, one to lift up the skirt and another on the back to propel. Asked by stjdarylthomas - Mon Mar 3 22:25:30 2008 - - 1 Answers - 0 Comments A. Well there are some things we don't know. A hovercraft needs to blow down (and fill up a skirt) in order to hover. And it also needs to blow "back" in order to move. I reluctantly say back because really it needs to blow opposite the direction you want to move AND it is nice if you can use that force to stop as well. (You can reduce the blowing out the bottom and drag your skirt too, but this eats up your skirt). What we don't know from your question - are you using separate blowers or the same blower? If the latter, you will need to divert some of the blowing for hovering and some for propulsion with some ducting. Think of the side view of the hovercraft. For simplicity, lets assume it is a rectangle. Along the bottom edge, you… [cont.] Answered by ncwalker05 - Mon Mar 3 22:55:11 2008 Is the jet engine a dead end in propulsion methods of that nature?
Q. Can it be more fuel efficient? An aircraft engineer answered and I am sure very correctly why there could not be and electric powered jet engine. The engine in a tank and a plane are the same. But... Could not the ducted fan idea be combined with the turbo jet idea to make a more fuel efficient engine, I mean 4 gallons a mile is not war friendly. Could not the spining of the compressor be electric and the fuel burning made more efficient in a plane engine? Asked by Rev Z - Mon Aug 31 20:11:08 2009 - - 5 Answers - 0 Comments A. I think people have done a lot of thinking about that and probably tried the ideas you had posted. If the jet engine could be made more efficient then it would go farther and faster and maybe higher. You should try NASA or the NIAC and see what they predict for the jet engine. Answered by john c - Wed Sep 2 22:12:17 2009 From Yahoo Answer Search: "Propulsion" See also:
