User:VogonFord I added a section on the X-15-A2's dummy scramjet. I was not logged in at the time, though.

Russian discrepencies

"First working scramjet "Holod" in world flies on 28 November 1998 reaching speed 5.8M. But collapse of Soviet Union stops funding this research and development of next generation of Russian scramjets is still suspended."

If it was in 98' how could the fall of CCSI stop the funding of a nation that fell 7 years prior? Uopmegabytes 11:01, 17 March 2007 (UTC)[reply]

In fact most of those tests were of a high speed ramjet (ie subsonic combustion). The one final test which should have had supersonic combustion was not completely successful, and had an engine unstart. After some time it restarted and flew with stable combustion. Analyses of the data are somewhat unclear, with the official CIAM position being that supersonic combustion was achieved, and all publications which I've read saying that the data is not clearly showing supersonic combustion. In fact the program was probably defunded because most of the money was coming from France and the USA, and in the absence of a clear win, they preferred to fund internal projects. Just as a side note: "Holod" referrs to the flying laboratory system (Fuel/telemetry/control) and not to the engine itself. As far as I understand, the tests of the holod system itself were a resounding success and it's available for anyone who wants to do supersonic flight testing. AKAF 08:51, 19 March 2007 (UTC)[reply]

I too found that NASA was funding and supporting the Russian tests and that Australia claims to have the first supersonic combustion tested engines. Without international help Russia would have had no testing at all. I think it might be appropriate for the article to reflect the lack of Russian success and independent research they have contributed to scramjets. Uopmegabytes 02:25, 20 March 2007 (UTC)[reply]

Maybe, but please try to avoid and remove nationalistic statements, they just lead to edit warring. You can look at my short explanation of the problems with the simple nationalistic approach in my recent edit to scramjet.AKAF 08:41, 21 March 2007 (UTC)[reply]

I might mention that the Australian tests were not an engine. They vented the combustion gases out the side generating no thrust. Thus it was just a supersonic combustor. http://www.americanscientist.org/issues/pub/a-burning-question DieselDude (talk) 19:01, 4 June 2013 (UTC)[reply]

DARPA Vulcan

Where does Vulcan fit into this? —Preceding unsigned comment added by 76.11.79.206 (talk) 02:38, 7 June 2009 (UTC)[reply]

List of scramjet powered flights

Is there anywhere a List of scramjet powered flights/tests with dates, speeds and durations ? Rod57 (talk) 16:17, 1 January 2010 (UTC)[reply]

Project HARP

There is no mention of the several 16" Scramjet Projectiles fired during Project HARP.

that is where some real research came from to developing a functional freeflight Scramjet. I also have the photos of the firings of these scramjets at both facilities. Vermont and Bermuda. —Preceding unsigned comment added by 208.74.37.17 (talk) 23:05, 15 February 2010 (UTC)[reply]

GLL Holod wiki link to Kholod

I have removed this link because from looking at russianspaceweb.com it does not appear to be the same. However I am not an expert so could someone please verify. Note: If re-adding the link please add a reference and consider updating the Kholod article.
