When Was the First Strut-jet Ever Built?

[KJ_Lesnick]

Does anybody know when the first strut-jet design was built?

KJ Lesnick
BTW: Did Paul Csysz ever mention such a system, or did any of McDonnell/McDonnell-Douglas' design use them? Assuming it's not classified and all...

Looks like the Strutjet patent was issued to Aerojet in 1993:

Aerojet tested the Strutjet in NASA's hypersonic tunnel in 1996:

Then again in its own facility in 2000:

Saw the strutjet mentioned in some older messages on the McDonnell-Douglas Orient-Express thread and thought this might be a better place to add this info. Much strutjet work was done under the NASA NGLT program under the ARTT/ART banner. Later work was done under ISTAR as the strutjet was the initial concept chosen by the RBCCC (Rocket Based Combined Cycle Consortium, consisting or Aerjet, P&W and Rocketdyne). Some program info:

The engine later morphed into a more P&W design.
