Please note that "Argus As 014 Staustrahltriebwerke" translates into
"Argus As 014 RAMJET"
And NO, a gas turbine is NOT closer to a RAMJET than a Pulsejet
because neither the Ramjet or its primitive form, the pulsejet have a
compressor or turbine. My original comments on the pulsejet has always
been that the Germans were the ones that called it an intermittent
ramjet, or athodyd.
The V-1 was launched off a ramp or an aircraft at 250 mph for the
pulsejet to work independently. On the ground the firing of the engine
(according to numerous sources) lasted just 7 seconds by remote
control with compressed air and fuel pumped into the stovepipe to get
it up to operating temperature.
It was the 16-17g launch up to 250mph that got the As 014 operating
independently.
Sources:
"German Weapons of World War II": "the launch gear was important,
since the pulse jet engine needed to be at flying speed before it
would work"- pg 114
"Germany's Secret Weapons in World War II": "The device must be
accellerated by some external means to a critical threshold velocity,
something of the order of 300km/h (186 mph) before it will work..."
pgs 62-63
" the launch procedure was straightforward. The pulse jet was fired up
and allowed to run for 7 seconds, bringing it up to the correct
operating temperature" pg 66
rest of launch sequence as in my earlier post pgs 66-67
"The Last Year of the Luftwaffe May 1944 to May 1945": "The missile
accelerated rapidly and when it left the end of the 156 ft ramp it was
moving at 250 mph, comfortably above minimum flying speed" pgs 81-82
"German Secret Weapons of the Second World War" by Ian Hogg: "just off
to the left side of the ramp was the 'distributor unit' mounted on a
steel platform. This carried more compressed air tanks, pressure
guages, and distrubution valves supplying compressed air to the
missile, firstly to blow air into the front of the duct and simulate
flight, and secondly to switch on the fuel valve (and switch it off
again should there be any malfunction). There was also a transformer
and trembler coil which supplied power to the engine spark plug by
flexible lead" pg 20
Get the picture now? The V-1 pulsejet wasn't running on its own on the
ramp.
I have lots more references should you require them.
