[edit] engine explanation

Why was there so much detail in explaining basic turbojet and ramjet operation? Those topics have their own articles. The only significant parts about the J58 design are its movable spike inlet and the union of two propulsion techniques. Everything else is standard turbojet/ramjet tech.

• The moveable spike inlets are not part of the J-58 design. They were created by Ben Rich as part of the Oxcart project. I will strike mention of them from the article unless anyone objects.

I object. The inlet design of a jet engine is very highly coupled with the engine, and this engine probably more so.WolfKeeper 18:10, 2 January 2007 (UTC)

I agree. Johnson makes it clear in his bio that the inlet design is The Big Deal. —Joseph/N328KF (Talk) 18:52, 2 January 2007 (UTC)

[edit] Suggest Including Term "Variable Cycle" and Additional Details

I think the amount of descriptive info on turbojet/ramjet operation is appropriate as written, at least of this date.

It's important to include the descriptive term "variable cycle" when referring to the J-58. Also explain what that term means. While the J58 is an example, it doesn't just mean turbo/ramjet. E.g, the GE F120 used to power the F/A-22 is a variable cycle turbofan/turbojet.

Here's some more info on how the J-58 works: [1] Joema 13:15, 20 December 2005 (UTC)

I incorporated some of the above. Joema 11:43, 29 March 2006 (UTC)
