Yeap ... We call that a "Can annular" combustion chamber concept. One of the aircraft that use to have such engines was the famous F-4 Phantom in its early stage, but I think it was later upgraded with "Reverse Annular" chamber engine later on ... But don't quote me on this last one, but I am quit certain with the previous.No. 44 wrote:You know, I've taken a peak at some of the first gas turbine engines and it seems that one of the original attempts by Frank Whittle involved placing several small combustion chambers around the compressor/turbine. The compressor would force air into the combustion chambers and the exhaust would be recombined at the end when turning the turbine and exiting the assembly. Maybe Zippiot was onto something by placing several pulsejets around a super-sized turbocharger.
One of the major reasons and/or advantage of a "Can Annular" concept, is that individual chambers are easyly replaced if damaged or cracked occures instead of splitting the engine in aft for changing the entire chamber. But again, I think this is also the reason why the Phantom was also know as the "Smoker" for this perticular engine concept was know to leave a trail of smoke behind, which is not that good when trying to avoid detection in a war scenario. Actually, the never knew and found out why this engine was smoking that mutch and talking to an EX Phantom engine mechanics years ago ... Lolllllll.
But I personally see this concept coming back, especially with the outcomes of better Pulse-Jets and PDE engines for I lately read that there are few new projets involving Pulse-jets and PDE engines on NASA tables. But you will need to check this one out.
