message: The accidental deployment of a thrust reverser during flight is a dangerous event that can lead to loss of control and destruction of the aircraft.
It's nice to see that the Lauda B767 is remembered, but does in-flight reverser deployment happen often enough that a broad statement such as this is warranted, or might it be better if the Lauda incident was more directly acknowledged? 59.167.244.69 12:14, 19 June 2007 (UTC)

message: There are "toy" jet engines available, eg Jet Cat USA and Wren Turbines UK that develop between 5 and 50 lbs thrust, available in turbojet, turboprop and turboshaft configurations for radio controlled planes and helicopters. See a functional description here. Is it appropriate to mention these in the Jet Engine articles? Chalky (talk) 05:25, 14 January 2011 (UTC)
replies: text: They deserve their own article, if you feel like it. I wouldn't put too much in here, as jets are relevant to miniature models, models are much less relevant to jets overall. We did at one time have coverage at Gas_turbine#Scale_jet_engines, but this has been eroded quite a bit from when I last saw it. Incidentally, there are gas turbine turboshafts out there as well as pure-thrust jets. There was a chap on the model jet builder's association stand at the Bristol model engineering show who had a turbine-electric loco chassis on display.

message: How the heck can nozzle temperature remain the same whilst turbine temperature increases?  The statement makes absolutely no sense!  The purpose of increasing the compression ratio is to correspondingly increase the burn rate of the fuel...  a higher compression ratio allows the engine to burn more fuel at any given time or to run more efficiency.  Combustor inlet temps have little to do with nozzle temps, or even turbine temps for that matter - this is because combustor inlet temps are much, much lower than outlet temps and the net transfer is low.  That said, compressed, pre-combusted air that's used to cool the nozzle, will invariably become less effective at higher temps.  — Preceding unsigned comment added by 211.27.67.97 (talk) 07:46, 3 August 2012 (UTC)

message: Turbojets seem to be used as backup in power plants. It is a cheap oil turbine easy to start and fast to connect to the network. (Engie Electrabel in Belgium in the news these days.) Is there literature on this in general? It would be then worth mentioning in the page. --Dominique Meeùs (talk) 07:18, 23 November 2018 (UTC)

message: The article says: The turbine exhaust is then expanded in the propelling nozzle where it is accelerated to high speed to provide thrust.  I would think that expansion would slow down the exhaust gases, not speed them up. Gah4 (talk) 00:19, 26 May 2022 (UTC)
replies: text: The statement is correct. Exhaust gas enters the propelling nozzle at high pressure and exits at atmospheric pressure. This represents a substantial fall in pressure, causing the exhaust gas to exit at lower density and higher speed. The mass of gas leaving the nozzle in a given time must be the same as the mass of gas entering the nozzle in the same time. Dolphin (t) 22:06, 27 May 2022 (UTC)
