Merge with Liquid-propellant rocket[edit]

Cryogenic engine redirects to Liquid-propellant rocket. It seems like there is redundancy here. Jojalozzo 02:43, 16 April 2010 (UTC)

I've fixed this redirect. Yes, there is a little redundancy in the contents of Liquid-propellant rocket and Cryogenic rocket engine, but not enough to merge (my opinion). --Kubanczyk (talk) 22:36, 17 April 2010 (UTC)

india has developed its own cryogenic engine. needs to be verified. —Preceding unsigned comment added by 117.195.200.189 (talk) 20:38, 1 January 2011 (UTC)

Not only has India developed its indigenous cryogenic engine it is one of the most efficient engines of its class in the world as far as specific impulse is concerned.

Article scope is unclear[edit]

Question about article scope. The article is about cryogenic rocket engines, at least as far as its title is concerned, but never defines its terms.

  1. Are we talking only about LH2/LOX engines? (as this seems to be the major focus of the article)
  2. What about cryogenic oxidizer but non-cryogenic fuel (like RP-1/LOX rocket engines? Seems that they are cryogenic too, but not represented in the article.
  3. What about non-governmental cryogenic engines, like the SpaceX Raptor Liquid methane/LOX engine now in development? ... or the SpaceX Merlin rocket engines currently flying, and currently in their third generation of engine model? I realize that 95%+ of all rocket engine development efforts to date are governmental programs and government funded, but not all of them are. What should this article be about?

In my view, it is necessary to define our terms, and then editors can help improve the article by editing it over time to better cover that topic scoope. Cheers. N2e (talk) 21:03, 7 January 2014 (UTC)

I don't know what government has to do with any of this, since all engines are built by private companies, not governments. But, generally, cryogenic refers to LH2-LOX while semi-cryogenic refers to LOX-RP1, LOX-ethanol or LOX-liquid methane, but no article has yet been created for semi-cryogenic engines.
