Gad! What crappy pics! I know film cameras well; I used to build my own from scratch- Got a lot to learn about this new digital I bought for the expressed purpose of posting pics on this site. Sorry about that, but it was just to give a peek at something really big. RG PS Vern- Thanks for the tip ab...

Well, just for the fun of it, I made a sketch of the KLM, scaled up to 18 inches cc dia (dome dia). (as-built dims) The scaling factor is thus 7.146, for diameters. The square root of this number, 2.673, was used to scale longitudinal dimensions. Then I made another sketch of the Sveldt Lady, scaled...

Looks really neat; I like it. Next, we need to increase cc diameter to 18 inches. Useing the square-root scaling rule, what would it llook like? Haven't drawn this up yet; maybe today. Bet it'll be a real fatty. How big can we go before the SFC drops off the map? Great stuff, Vern. Keep on truckin'....

re: Window in combustion chamber?

G'morning all-

I believe saphire has been used for windows in high-temp burners.
Saphire has very good thermal conductivity and can be cooled with
with forced draft. This might make a good window for a turbojet
burner can. An outfit named Melles Griot makes them.

re: Window in combustion chamber?

Howdy all- I wonder if something along the lines of a pin-hole camera could give us a view of the interior of a running engine. I cut bottom off an empty beer can, and poked a hole in the side with a pin at half-height. I then placed this over a candle, and holding a piece of mylar drafting film bef...

Jerry-

Been trying to post a pic of the XP-67, but I'm struggling with

re: Favorite aircraft

Thankx, Jerry- The wimpy engine thrust was pretty well known, but the this is the first I've heard of the poor pitch response. A very good read regarding the X-3 is abook entitled " The Lonely Sky" by William Bridgeman, the primary test pilot for the X-3 program. It was published in 1955 and may be ...

re: Today's tidbits

Howdy, guys-

Say, did you know that LOX is magnetic?(!)
Visit www.chem.uiuc.edu. There is a short video showing the LOX being
trapped and held between the poles of a strong permanent magnet
and evaporating. Give anybody any ideas? Maybe a pump, or
something.
