Talk:Hypergolic propellant

message: Why isn't this a "true" hypergolic?  In an article on rocketry, the crucial factor making hypergolic propellants of interest is their simple and reliable ignition, without the need for separate igniters and the risk of hard starts. Although the British HTP / kerosene engines did use a prior catalytic decomposition, they had all the engineering benefits of being hypergolic engines (just look at their reliablilty record, compared to their contemporaries). In a purely chemical context, the question of whether cold HTP + kerosene is hypergolic is indeed arguable, their place in rocketry seems secure. Andy Dingley (talk) 13:13, 28 April 2008 (UTC)
replies: text: hypergolic means the two propellants spontaenously chemically ignite on contact.  Kerosene and H2O2 do not. DonPMitchell (talk) 19:12, 3 November 2008 (UTC)
replies: text:  Kerosene and _hot_ HTP (from the prior catalytic decomposition) are hypergolic though. Andy Dingley (talk) 10:01, 4 November 2008 (UTC)

replies: text: hyper + ergein ("lots of work = energy"). So hyperergolic. Say that quickly ten times and you will have reduced it to hypergolic. 2A01:CB0C:CD:D800:ED8F:60EF:8209:7153 (talk) 15:35, 11 April 2021 (UTC)
thread_title:  Etymology? 

message: Strictly speaking it's the propellant combination that's hypergolic, not the propellants themselves. I've restored a sentence that stated that the term "hypergolic propellant" is commonly used, even though that's not strictly correct. John added a cn tag to this, but the title of the article itself presumes that it is in common use. If we don't want to state that, then we should perhaps rename the article to just "Hypergolic".

message: Just for interest the RZ2 MK3 engines used on Blue Streak used a hypergolic starter. This was put in place By the RR representative just before the floor beneath the engine chambers was removed. The starter wires lashing about as the main engines ran up at -4secs was a problem, bearing in mind the nickel tubes of which the engine chambers were formed, were not overly strong.Drg40 (talk) 19:11, 8 July 2019 (UTC)

message: Hello all, I have gone and changed some names around and added further historical context based mostly around Clark's book
I have also deleted the first citation needed section in the "history" section as I could not find any evidence of this and Clark lists Walter specifically as the first to stumble upon hypergolicity
I am fairly new to Wikipedia, so review and help would be appreciated, please let me know if I messed anything up.
Thanks all! Mameyn (talk) 19:48, 14 September 2021 (UTC)
