edit: The smallest of proposed fighter designs has similar dimensions, and the same 1,5 m diameter ramjet as Skoda Kauba SK P.14.01, but it has different wing configuration and wing area.

How big is the PDF ? This cut-down Browser_PC 'fell over' and only showed the very top of the title page.


Not being able to read it myself, I must ask how did they get the ram-jet lit for ground running ??

It's 23,7 mb. 81 pages, and it contains recognizable test, so you could search in it (it's not perfect. It can't recognize all words...).


I didn't read the whole document, but I was curious about that too. As far as I know it would take off with two jettisonable solid fuel rocket producing 3 tons of thrust. The rockets are placed on the sides of the ramjet tube, or inside for reducing thrust differential.
According to the take-off graphs, the ramjet engine burns fuel from the start. Solid rockets are jettisoned after 30 seconds, at the speed of 145 m/s (522 km/h, 326 mph). I guess it's the "safe" speed for the ramjet. It also means that it couldn't approach the runaway under power. Pilot would have to decelerate in gliding flight and than land the plane.
------------------------------------
The document contains graphs that mention "jettison of bombs" points. Interesting... :eek:

I hope you can solve your problem with the pdf.

Edit: Ignition of fuel effected by injection of small quantities of zinc diethyl or by electric spark plugs.

No no no,it was not it my dear Richard,

Please my dear Jemiba,clip this topic to a new topic as I did,the Skoda Kauba SK P.14
was a well known aircraft,and called Sänger Staustrahljäger,and the fighter which I spoke
about it was developed from it but was not related to Skoda,it was called Sänger Überschall-
Staustrahljäger,or a supersonic ramjet fighter.
 
If it was a design by Sänger, it's well suited here, as this topic covers such designs, not just the SK P.14 .
"ÜberschallStaustrahljäger" (supersonic ramjet fighter) is just a description, that fits to several of those
designs, too.
For a dedicated topic we need way more information !
 
Unfortunately no more Info my dear Jemiba,

and after you edited the title,OK it's good to put it here,I will try to remember
the source,all I reported is; with improved Lorin-jet engine.
 
Hi,

all we know; he had two versions,one had 20.000 hp and the other had 40.000 hp power propulsion ?.
