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.

On a related note, grain silo explosions are a real thing, and there are codes having to do with ventilation of air space above the grain mound for that very reason.
Thanks BenLurkin. Interesting, but WWII, so no ping.
Is it bizarre that this thing looks like the vehicle mode used by Decepticons jets before they came to Earth?
The question is what did we do with the Lippisch Delta after we got it, ;-).
It would work, the Verhees Delta proved it..
G1 cartoon and comics, obviously.
Would probably have an unbelievable smoke trail pointing allied fighters to the small airstrips from where they originated.
Coal-fired? Amazing some of the things the Germans came up with.
Presumably takes off as a rocket. Lowers gear (not powered) to land
