"Missing" U.S. Military Aircraft Engines

[airplane176]

I am looking for any information on "missing" U.S. military aircraft engines for my website at http://aircraft.list-of-domains.org/, specifically the engines listings here: http://aircraft.list-of-domains.org/Engine.htm.

T59

PJ30
XPJ34-MD-8 I have seen this only in a posting here: http://www.pulse-jets.com/oldforum/se.php?subid=391&seid=0&senr=0&forum=valveless
PJ36
PJ38
PJ43
PJ44
PJ45
PJ47
PJ48

There are mention of numerous pulsejets from the 1940s and 50s, but usually only by manufacturer and nominal diameter, i.e. Continental 14-inch for the KD2C-1, McDonnell 7-inch for the KDD-1, 8-inch for the KD2G-1, 14-inch for the KD2C-2, 14-inch J-9 and J-11, several Marquardt...

RJ30-MA I have info on Air Force odd-numbers, but none on evens except -8. I know it was tested by the Navy on an F7F plus others.
RJ32
RJ33
RJ-34-MA
RJ36
RJ38
RJ53
SJ61 by Pratt & Whitney. Is this a company designation?

Again, there are examples such as the Hiller 8RJ2B for the YH-32, McDonnell 7.25-inch for the XH-20, numerous Marquardt, Bendix...

LR4
LR14
LR18
LR60
LR61
LR68 up even numbers if allotted
LR69
LR95
LR97
LR111
LR123
LR125
LR127
LR131

Thank you.

Go to http://www.designation-systems.net/usmilav/engines.html. SJ61 is clearly a company designation because there is no SJ (scramjet) category in the MIL-HDBK-1812 engine designation system. RJ30 and RJ34 were assigned to ramjets (the RJ30 was used to power the Navy's KDM drone). The entry "XPJ34-MD-8" is probably a typo for PJ42.

Hey Roger, did you get the info. I turned up on the Marquardt 20 and 30" engines? What do you have on the 30"ers? Kevin
