The coal was to take the form of small granules instead of irregular lumps, to produce a controlled and even burn, and the basket was altered to a mesh drum revolving on a vertical axis at 60 rpm. A jet of flame from tanks of bottled gas would fire into the basket once the P.13a had reached operating speed (above 320 km/h), whether by using a rocket to assist take off or by being towed.
The air passing through the ramjet would take the fumes from the burning coal towards the rear where they would mix under high pressure with clean air taken from a separate intake. The resulting mixture of gas would then be directed out through a rear nozzle to provide thrust. A burner and drum were built and tested successfully in Vienna by the design team before the end of the war.
The P13a was made of wood, plywood and steel tubing. One-piece wing of open rib design, cantilever, vertical and horizontal stabilizer surfaces were hinged, with trim tabs in the interior portion. There was no fuselage in the normal sense, the cockpit was located in part within the forward portion of the vertical stabilizer, in part just behind the forward leading edge between the two main spars.
A window in the lower forward floor provided better view at high angles of attack (during landing at roughly 35 degrees). The triangular vertical stabilizer had a similar profile as the wing. Trimming was accomplished by a manually operated water transfer pump 9 gallons from a rear tank to a nose tank and back. The tricycle landing gear, which could only be retracted on the ground, had a 23 inch travel stroke.

Was watching Nazi Mega Weapons episode about the German type 21 submarine developed at the very end of the war.
If that was put into operation two years earlier, they would have owned the Atlantic. Incredible forward thinking machine.
The tricycle landing gear, which could only be retracted on the ground,
???
Nah... we would have still won. They never built a VT fuse that was any good. And we had ASW down to an art by the time that sub was built.
Near as I can figure, that means the aircraft was designed to be launched with the gear up (eg rocket propelled up a ramp). And the wheels were only lowered for landing.
The German military leadership was told to be ready for war in 1946.If Hitler had stuck to the plan we would all be speaking German right now.
Wood and plywood + Mach 2 = 10+ pucker factor
Not to mention the fuel’s combustion happening right under the pilot’s seat.
The German engineers were nothing if not daring. The fail factor would have been apparent long before such speeds were achieved.
The idea of using finely pulverized coal as a fuel is ingenious in several ways. The vastly increased surface area of each particle of coal dust would greatly expand the burn exposure, making it a two-fold advantage. There would be a first burn, creating two carbon monoxide molecules, both of which would reburn forming two very hot carbon dioxide molecules, with adequate oxygen supply.
Actually, finely divided cereal flour would be nearly as effective if used as a fuel in this manner, as there are conditions in which explosions have occurred in grain milling plants, if ignited by a static electric spark or the act of lighting a cigarette.
Bizzaro world chronicles, but what good is a warplane without weapons? 2 machine guns?
Typical “Luftwaffe 46” Sifi fantasy stuff
I don’t doubt that coal dust could be used as a fuel, nor that the proposed engine wouldn’t work, but I seriously doubt that the craft could carry enough coal for more than a few minutes of flight time.
Interesting opinion, but you need to explain your rationale. I completely disagree with you, though.
All I know is when I play Axis & Allies and invade Britain before attacking Russia, I always win :)
Kinda gives new mea ing to the term “ram” jet
From looking at the wings, Mach 2.6 would be a pipe dream. At Mach .95 that thing would shake itself to death and turn into splinters.
Did they do any trans-sonic wind tunnel testing?
Sorta like a half assed version of black powder.
