allright, time to give something away...

I've got too much stuff on my workbench, so heres a question...

winner will recieve something automag related.

where do the oblique shock waves converge to on a ramjet?

let the games begin :)

[BeaverEater]

Why dont you just kick me in the face, it would be less painful

[teufelhunden]

They don't



[I think, from reading thru some PDFs google found.. damn this high level crap.]

they converge in the inlet :cheers:

turbine housing?? i dont even know what you are refering to!!!!

[Rocp15126]

I believe that Pennzman54 is correct, they converg in the inlet duct (Supersonic or variable geometry).

[shatter_storm]

at the fuel injectors/combustion area. having convergence promotes the compression of inlet air - if they converge in front of or behind the injectors, the engine just doesn't work.

edit: oops, I think that's a scramjet, not a ramjet. I can't remember how ramjets work.

[Enemy]

are we talking car motors or turbine/aircraft engines?? car moter=intake runner right above the carb that feeds straight into the aircleaner.. aircraft right after the turbine just before the fuel is added tot he mixture.. obviously im guessing on the last one!

[Rocp15126]

hmmm. Shatter-Storm you may be correct. If I remember correctly the flame holders located in the combustion chamber provide blockage to slow down the airflow (to mix and ignite the fuel and air.) I remember the inlet duct being a key factor, but you may be right about where the waves converge. It's been a long time since I thought about powerplant design. Must have a lot of Aerospace engineers around here.

Everybody knows that oblique shockwaves are produced when supersonic flow passes over a wedge, in a ramjet the wave converges at the supersonic diffuser cone and in scramjets the oblique shockwave converges at the nose of the vehicle. "A ramjet cannot work without a shockwave. The flow in the combustion chamber must be subsonic. Remember what happens to total temperature as it passes through a shock: It remains the same. Also note, that by slowing the flow down you convert most of that to local temperature. If you had a ramjet engine in a Mach 6 flow, the temperature inside the combustion chamber would be over 2000°C! Not only is that temperature hot enough to damage the internal components of the engine, but there is very little energy which you could get by burning the jet fuel."

[Bad_Dog]

I'm looking for a term that describes the location... to be more spacific :D

either way I'll check with my source to see if any of your answeres are correct (or close enough)...

[Bad_Dog]

pennzman543 you are the winner.

"inlet" is technically correct, I was looking for the "cowl lip" which is a part of the inlet but your answer is very close...


now what do I give you.. lemme go look....

The Ramjet Is Like A Supercharger. Housed Over The Intake Manifold. They Converge In The Intake/carbeurator.

[germanman]

Aww, Damn! I Get A Car Question Only To Lose Cuz I Was At An 8 Hour Martial Arts Seminar. Tear...

[Mister Sinister]

Ummm sorry dude not a car question... A ram jet is a type of a jet aircraft engine... I think your thinking of Ram Air... which is just a scoop.

[Enemy]

there was a ram air called ram jets on an old school muscle car thats why i was hella confused!! congrats on who won!

[pennzman543]

what did i win :confused:

i am pumped :clap:

[germanman]

heh, i know cars, not jets.... oh well. now i know something new thnx sinister. i owe u a drink :cheers: .

[Bad_Dog]

you win a brans spanking new bolt spring :cool: !1!!

(sorry I actually found a buyer for the lvl7 bolt I was going to send you :p )

PM me your address :D
