"blow-down"?

What is a "blow-down" rocket engine? The term is used to describe an engine made by Armadillo Aerospace in another bipropellant rocket engine article: "The rocket engine is a LOX-Ethanol, film-cooled, pressure-fed, blow-down design." The description comes from the Aerospace Testing International article, pp. 52, that is used as a source for that article. Thanks. N2e (talk) 06:38, 5 January 2011 (UTC)[reply]

It's a simple type of pressure-fed engine. The pressure in the propellant tanks isn't regulated, so it is determined by the pressure in the pressurant tanks, which decreases as pressurant is being expelled. Martijn Meijering (talk) 07:49, 5 January 2011 (UTC)[reply]

Cycle Type Table stuck in External Links section

As the title says, for whatever reason the Cycle Type tables appears to be stuck in the External Links section instead of the Engine Cycles section. This causes the link template of the bottom to be jammed into one of the cells of the table. Even stranger is that it apperas to be in the right place in the source code, and it's in the right spot in the section edit window. -InvisibleUp (talk) 23:54, 22 April 2013 (UTC)[reply]

Just table syntax. The table wasn't closed properly. These things are always a pain. Andy Dingley (talk) 10:39, 23 April 2013 (UTC)[reply]

External links modified

Hello fellow Wikipedians,

I have just modified one external link on Liquid-propellant rocket. Please take a moment to review my edit. If you have any questions, or need the bot to ignore the links, or the page altogether, please visit this simple FaQ for additional information. I made the following changes:

Added archive https://web.archive.org/web/20071201210444/http://liftoff.msfc.nasa.gov/news/2003/news-goddard.asp to http://liftoff.msfc.nasa.gov/news/2003/news-goddard.asp

When you have finished reviewing my changes, you may follow the instructions on the template below to fix any issues with the URLs.

The principles of operation is wrong. Solid rocket boosters also suffer from center of mass issues. This must be fixed. i don't know how 2 edit — Preceding unsigned comment added by 99.43.252.75 (talk) 19:57, 1 December 2020 (UTC)[reply]

Appealing Aspects of Liquid-Propelled Rockets

Lsnellin (talk) 21:05, 20 November 2023 (UTC) Under principles of operation, there is a section containing a list of issues associated with liquid-propellant rockets. However, there is not much content highlighting the advantages of liquid-propelled rockets, and why they are the most common propulsion system in space exploration. I believe that a section with this information in it would be relevant and beneficial to this article.[reply]

Recent edits address this with a new Advantages and disadvantages section. (— 𝐬𝐝𝐒𝐝𝐬 — - talk) 02:46, 14 February 2024 (UTC)[reply]
