Missing Engines[edit]

Shouldn't this template include the three new solid rocket motors that successfully flew on the ESA Vega flight in February? The Vega has the P80 first stage, the Zefiro 23 second stage, and the Zefiro 9 third stage. — Preceding unsigned comment added by 157.166.167.129 (talk) 23:00, 24 February 2012 (UTC)

Some missing engines include RD-171 RD-108 RD-0110 ArkianNWM (talk) 17:47, 7 August 2012 (UTC)


Template Scope[edit]

What engines are appropriate for this list? Is it only for launch vehicles? Only for engines that have flown? Undergone significant development/testing? Thoughts? ArkianNWM (talk) 17:10, 7 August 2012 (UTC)

Poor Classifications[edit]

The way I understand this template, is that it is trying to list all of the engines that have ever flown on a major rocket powered vehicle, and not just a subset of those. My issue then is that the classes that these engines are arranged into don't cover all categories. More directly, the classes are too narrow. LOX/LH2 are not the only cryogenic fuel combo, LOX/RP1 are not the only semi cryogenic fuel combo, and there are engines that use no cryogens but also do not use hypergols. I know that there are a couple of engines currently undergoing testing that use LOX/LCH4 which are both cryogenic. I don't know if any engine systems exist which would be appropriate for this list that use these, but LF2, NO2, and HTP are potential oxidizers that are excluded from this list and there are many fuels other than RP-1 that are excluded from this list including gasoline, LCH4, and Syntin.

When has RD-0146 flown?[edit]

The template currently shows RD-0146 as a "flown" engine. When, where, on what vehicle? (sdsds - talk) 23:29, 19 July 2014 (UTC)

Vinci[edit]

Vinci was included when this template was just "rocket engines," but it has not yet flown... and probably won't for several years A(Ch) 00:17, 27 July 2014 (UTC)
