Re: What Fuel
Hi pyrojoe,
The cracks that occur in old brass items are a metallurgical problem called " season cracking " .
This condition rarely occurs in modern brass products that are properly heat treated during manufacture.

Re: Miss Galveston - Land, Water or In the Air
Hi Irvine.J,
Music wire is high carbon steel which is pre - hardened during the drawing process, and is about as hard as any tool steel tool that You might use to try to cut it.
The best method for cutting it is to use an abrasive cutoff wheel or the corner of a grinding wheel.

Hi,
Figure 29 in the Russian pulsejet manual shows two rectangular floppy valves, but since I can't read Russian I don't know what the article says.

vortex
Hi pyrojoe,
The item is defined as a vortex cavity or vortex cell. It might be referred to
by adding circumferential to the description, if it is in a tubular combustor.

Hi Jim,
I don't think that the ex-Cuban dictator makes castor oil, but Castrol does.
Sorry, sometime I can't restrain My warped sense of humor.
