thread_title:  Citations Banner on Advanced Nozzles 

message: I've just updated the section and after looking back through the links have realised that there is much confusion over 'plug nozzles' (so maybe this discussion should be in that section too- EDIT: it is!!). Anyway, my understanding is that a plug-nozzle is much like an aerospike but without the base pressure component supplied by a base-bleed. Most articles I've read support this (http://pdf.aiaa.org/preview/1998/PV1998_3522.pdf) so I was wondering what evidence there was for plug nozzles and ED nozzles being confused. --RedHotIceCube (talk) 02:15, 7 November 2008 (UTC)
thread_title: Advanced Nozzles confusion

message: JohnnoShadbolt, both spellings are acceptable. One is the American spelling and the other is the British spelling. It is my understanding that whichever of the two was used by the original author is the one that stands.  In this case, the original author used the American spelling, so I am reverting your change of the spelling. Regards, mbeychok 19:31, 18 November 2006 (UTC)

message: SpaceX recently released a video of the initial test version of the Raptor vacuum engine hot-fire test on a ground test stand, with an (intentionally) overexpanded nozzle on the engine.  Video here.
They are developing this interim engine design—where three of these engines will be used on the final version of the SpaceX Starship, the second stage of the SpaceX Starship system two-stage launch vehicle, simply because they need to initially test the vehicle and engine at sea-level—as they endeavor to design and iterate for a complete reuse of the second stage orbital ship.  Thus, lots of flights of the six-engine second stage, with three Raptor vacuum engines on it, under sea-level atmospheric pressure conditions.  Very interesting video footage.

message: Rocket are reaction engines. Why is the outside pressure relevant? Only the speed of the propellant should matter. In fact matching the ambient pressure seems like it should slow the propellant the most. Why is it?--88.100.176.55 (talk) 17:21, 7 April 2022 (UTC)

message: A rocket engine uses a nozzle to accelerate hot exhaust to produce thrust. But how does it work? How does it function? Confidential Editor (talk) 14:55, 23 August 2022 (UTC)
