Nice article, although someone with a strong british agenda added remarks which would be better left out Stephan Schmidt

Agreed, and that was practically their only addition to my original content. Removing! Maury 13:33, 4 January 2006 (UTC)[reply]

Wasn't The first American turboprop was the General-Electric T-31?

Scope?

'jet power' is a very broad term.

Rockets, scramjets and the aeolipile are all jet engines.

If the article is about airbreathing jet engines it should probably say so; if it's only about gas-turbine based jet engines then the ramjet stuff needs to go.

But I think the article is talking about airbreathing jet engines, in which case scramjets need to be mentioned.WolfKeeper 15:54, 9 September 2007 (UTC)[reply]

I've changed my mind, I think all jet propulsion vehicles have to be included.- (User) WolfKeeper (Talk) 17:07, 21 July 2008 (UTC)[reply]

According to the definition in dictionary, Coanda 1910 was a jet plane

Even if Coanda 1910 had used just a ducted fan powered by a piston motor, the overall engine fits the definition of a jet engine. Coanda 1910 used oxigen to burn fuel and produced a backward discharge of gases that pushed the plane forward. This is in the definition of a jet engine.

Coanda 1910 was not a turbojet aircraft but definitely was a jet plane.

"Definition of JET ENGINE

An engine that produces motion as a result of the rearward discharge of a jet of fluid; specifically : an airplane engine that uses atmospheric oxygen to burn fuel and produces a rearward discharge of heated air and exhaust gases" source: http://www.merriam-webster.com/dictionary/jet%20engine

"jet engine

1. An engine that develops thrust by ejecting a jet, especially a jet of gaseous combustion products.

2. An engine that obtains the oxygen needed from the atmosphere, used especially to propel aircraft and distinguished from rocket engines having self-contained fuel-oxidizer systems." Source: http://www.thefreedictionary.com/jet+engine

All of this has been hashed out at the Coandă-1910 talk page where consensus is that the Coandă-1910 as shown to the Paris public is not known to have exhaust routed to help thrust. The aircraft never flew. Binksternet (talk) 22:46, 23 March 2013 (UTC)[reply]

Coanda 1910 was a jet engine working in the "Cold Thrust" regime, at least

Cold Thrust - Hot Thrust; Both regimes = jet propulsion

According to this page http://modelingmadness.com/scott/axis/ity/campinipreview.htm Campini Caproni jet plane could fly at 200 km/h using just the compressor, without injecting fuel and igniting the mixture.

"On the cold thrust alone, the Campini Caproni was capable of speeds over 200 kph, however with the addition of the 'afterburner', speeds easily doubled to 400kph."

In case Coanda had not injected and ignited fuel (or exhaust gases from the Clerget engine that turned the compressor) his Coanda 1910 power plant would still have been a jet engine working only in the "cold thrust" regime.

Hobbyists often use cold thrust jet engines (ducted fans powered by piston engines) for their model planes.

At the Coandă-1910 talk page the consensus was that the Coandă-1910 as shown to the Paris public was little more than a ducted fan driven by a piston engine. The aircraft never flew. Binksternet (talk) 22:46, 23 March 2013 (UTC)[reply]
