Eyeballing those pictures of the As044 and the Pabst ramjet - IMHO the
AS044 is a pulse jet (else why the square grilled inlet?) and the
Pabst ramjet is a neat way to convert fuel into smoke and noise. Its
specific fuel consumption (Kg fuel/newton/hr) must have been very high
indeed. I believe the ramjet fighter as pictured would have had a
range even less than that of the Me163b. (Little volume for fuel.)
Doubtless why it never made it off the sketch board.

Walt,

A pulsejet is a form of ramjet except that the combustion is
intermittent rather than continuous. The pulsejet uses spring loaded
shutter valves that open and close for the imtermittent pulse... but
is still a ramjet that has to be launched into the air by some means
other than the engine for it to work.
The Germans had both the As044 and Jumo 226 pulsejets under
development at the end of the war- both were investigated by the
Russians from '45-'47.
