From Google News Search: "Engines and Propulsion Systems" Apollo Service Module Question!? Q. I want to find out the chamber pressure of the Service Propulsion System or the main engine of the service module. I have found out the propellants used for the engine that are: Dinitrogen tetroxide and Aerozine 50 are hypergolic propellants. I would like to know it in atmospheres, if possible. For example, the SSME has a chamber pressure of 186.922 atm and the F-1 engine has a chamber pressure of 69.085 atm. This are just approximations not exact measurements. Thank you for your time.

Q. ok stick with me on this. i was waching the tv the other day about the current limitations of space travel. it talked about the waight of all that fuel needing to be hoisted into the edge of our atmosphier & blah blah blah...it talked about how inefficient the current system is. well i had an ideah to create a kind of nuclear sub but desighned from scratch that would be the opposite of a submarine (keeps pressure in not out) & powered by a small reactor. maybe even using a nuke sub engine & using sealed air/liquid pipes runing outside the ship to super cool air(or)liquid & return that air/liq or gelatin incapable of freezing, back to the reactor for cooling as space is verry cold. anyway take this reactor atached to a masive solenoid &… [cont.] Asked by 6-sick-6 - Thu Aug 27 21:24:04 2009 - - 2 Answers - 0 Comments A. Things of this nature have been discussed. The main problem is that earth's magnetic field (and that of any planet) is very weak, and falls off very quickly with distance. So you would need some way (with its own energy source) to generate all these magnetic fields. You'd effectively be making a very large but very weak linear induction motor. It's hard to imagine a circumstance where that would be practical. A Faraday shield plus a magnetic shield around the core of the spacecraft could protect the electronics inside.

Q. My Idea for solving Hydrocarbon Problems My idea consists of creating an electrical system placed upon our nations highways in the form of an interconnected highly durable plastic solar panel system. Imagine if all of our roads were covered with such a system! Once manufactured, in the form of large and long plastic rolls, the system would make up the top layer of the roadway. Plastics are being developed now which can store charges (batteries), conduct electricity, produce light (flexible television screens), and I would not doubt- also provide magnetic properties. By adding silicon in different property levels of ionic charge distributions, according to the movement of electrons flowing from lower energy voids to higher, solar… [cont.] Asked by studzywudzy - Fri Jun 30 12:33:32 2006 - - 12 Answers - 0 Comments A. The idea certainly makes me think...I love questions that make me ponder "now why didn't I think of that? It makes sense!" I'd like to answer a few questions and concerns which other answerers have brought to light. Semi-trucks can't stop hauling because America lives through the goods the truckers haul. And up here in MN, the river barges bring up alot of goods, but they can only run when the river isn't frozen...we'd be in big trouble without the truckers running in the winter months. The current road workers would simply switch materials, instead of laying asphalt and concrete, they'd lay solar panels and electrical wiring. And as for the oil industry employees, they can help maintain the new roadways. With a project like this, there'l [cont.] Answered by Moon Maiden - Fri Jun 30 14:50:59 2006 From Yahoo Answer Search: "Engines and Propulsion Systems" |
