Talk:Afterburner

Images

The image in this article doesn't exactly show an afterburner, but rather the exhaust nozzle. Perhaps a more illustrative image demonstrating an afterburner in action, such as this one http://www.globalsecurity.org/military/systems/aircraft/images/f-14-Carrier-Launch2.jpg could be used instead?

added pics

The first image on the page shows the SR-71 without an afterburner. For an article about afterburners, wouldn't it be more logical for the first image to show a plane with an afterburner? --Scottie theNerd 08:35, 22 February 2006 (UTC)

Could someone indicate what the increase in thrust might be when adding the afterburner?

Diamonds

Could somebody knowledgeable add a section on why you get diamonds in an afterburner exhaust? Cheers, miterdale 11:35, 19 September 2005 (UTC)

Air Combat Link

The link to Air Combat leads to a redirect to a computer game. Presumably there is some better link?

Confusing

This is a well written article, but, I do not know much about aircraft (probably why I am looking at articles like this one), and this page is almost impossible for me to fully understand without doing a whole lot of background research first. I don't have a clue as to what some of the words in this article mean, so could someone please dumn it down a bit, for people who don't know much about aircraft. Thanks!

"Principle" section error

"Then while they [the gas] pass the turbine they expand at a constant pressure thus losing temperature."

When gases expand through a turbine they lose pressure and temperature. For an ideal turbine the process is isentropic i.e. happens at constant entropy, not pressure.

See the article on the Brayton cycle and look at the P-V or T-S diagrams for details - it is clear that the pressure does not remain constant through a turbine.

Agreed, but in the text no reference is made to an "ideal" turbine, so the the text should read either

"Then while the gas passes the turbine, it expands at a near constant entropy, thus losing temperature."

or

"Then while the gas passes an ideal turbine, it expands at a constant entropy, thus losing temperature."

I know this is technical detail, but if there is any place that should be technically correct it's the encyclopedia, right? :)

And just to be thorough, you can read more about ideal and actual Brayton Cycles in Cengel YA and Boles MA, Thermodynamics - an Engineering Approach, McGraw Hill, 2006

Examples of increase in thrust

Shouldn't there be actual examples (figures) for the net increase in thrust (in percent) when using re-heat on a few particular planes?

It's all very abstract without... —Preceding unsigned comment added by 82.139.196.68 (talk) 20:22, 10 November 2010 (UTC)

Reheater

Reheater redirects here. however, a reheater is a very important, efficiency boosting heat exchanger in a power plant, should therefore be a separate article. —Preceding unsigned comment added by 194.53.253.51 (talk) 14:50, 22 December 2010 (UTC)

First, we need to make sure that such an article doesn't already exist, or should exist, under another name, or as part of another article. - BilCat (talk) 14:58, 22 December 2010 (UTC)

Is Thermal power station#Reheater what you are talking about? - BilCat (talk) 15:03, 22 December 2010 (UTC)

Reheat redirects here also. That is an alternate term for Afterburner. Maybe Reheater should redirect there instead (??). -fnlayson (talk) 15:36, 22 December 2010 (UTC)

Is Roll-Royce's Joe Holden the inventor of the afterburner

I was watching a video on youtube [1] about an inventor called Joe Holden (who was born in 1930 so the age is about right) who said he invented the afterburner whilst he was an apprentice at Rolls Royce, I think this would be worth investigating and rolling into the article Back ache (talk) 08:30, 5 August 2011 (UTC)
