A high percentage of solids in the combustion products mitigates the
effectiveness of aerospike nozzles. The solids do not behave like a gas in
other words.
But a good thought and for pure AP people might be a good idea. It actually had
been done before in the distant past and there was some chat about making the
nozzles available to HPR users.
Many thanks to Mark for the excellent documents. I have the originals but had
forgotten how much valuable information was therein... Chuck's thoughts on
nozzle design were particularly useful. And now they are electronic and in a
file in my laptop!

I'm wondering if any consideration has been given to the use of aerospike
nozzles in our endeavors? Seems to me that there is a significant performance
bump using this nozzle design as well as a significant reduction of base drag.
I doubt if anyone has used an aerospike nozzle on a sugar motor either - we'd
be breaking new ground!
Might be worthwhile to take a closer look at!

Great single-page source for some document downloads on issues that are quite
topical for our current phase of development and testing.
