Also, da von Euch nichts konstruktives mehr folgt, ist die Wahrheit für mich annalog
http://www.916-starfighter.de/Q&A.htm , dass das Heulen NICHT bei der B-58 oder vergleichbaren Maschinen vorkam/vorkommt, sondern typisch für einige F-104-Varianten ist:
1. What causes the "Howl"?
It is actually the simple event of two differing airflows coming together and causing a whistle! The engine is surrounded with bypass air, some of which is coming from the engine air bypass flaps, and some is coming from generator access doors and aft fuselage suck-in panels. This bypass air is mixed with heated air coming from within the engine, which has been heated due to it having passed through the compressor and hot section. The result is a mixture of heated air, that which has passed through the engine, and cooler air, that which has passed around the engine, all of which is forced to be mixed when it encounters the convergent/divergent exhaust nozzle system. What we have is two airflows, one heated and faster from the engine, mixed with a slower and cooler airflow, from around the engine, forced out through the exhaust. The result is a whistle. Some call it a howl.
What it really is, is J-79 installed in F-104, in operation. The howl is different in the 104 from the F-4 due to the differing
amount of bypass airflow in the 104. The howl is also different in dash -19 and -J1K engines due to the differences in the
convergent/divergent nozzle systems. It's still J-79, and we all love it.
