Engineers have found a way to boost the performance of liquid fueled
rockets. The secret is in the plumbing.

Finally perhaps we are now back on track. However, nothing wrong
with solid fueled rocket concept provided means is built in for
compartmentalization of solid fuel block cells in case of emergency shut
down need is necessary including advanced safety pilot compartment
separation possibility.

ponder on,

Oh yeah that's a good idea.. break the solid fuel into separate blocks so
it no longer has a even, uniform burn within the chamber.

Hey Night
Sorry to inform you 'ol Mangeymutt is correct about the
impracticality of throttling or shutting down a solid fuel rocket. Once
the thing is lit, it's gonna burn flat-out until it's expended or the
RSO (range safety officer) blows it up. oc

Yes Officer oc that's the present known technology understanding
concerning solid burning rockets, for the Russians captured and got the
heavy payload German rocket research team. Remember my net posted war
service years and I heated my coffee, tea, and hot chocolate using
chemical solid fuel. And when the call came to move out what do you
think I did to quickly shut down and preserve my fuel till the next fox
hole? Dr. Von Braun was indeed with the guidance and light weight
ordinance liquid fueled rocket team when the second war advanced science
teams got separated and he managed with his full team to escape to the
west. I am so honored that you named one of your planes the bat wing,
ha, ha, ha, don't think I had forgotten.

carry on,

Hi nightbat There is away for solid rockets to be shut down. The
chemicals have to be stacked in canisters. Timing would be every
thing.in case of problems. It would be a pulse rocket. Very short time
delays between when one finishes its fuel to the next one on top firing.
Not as good as liquid boosters that can be shut down,but it could be
done. I can think of ways. It should always be a must to have the same
method of escape engineering that the Saturn V had. Saw a jet fighter
plane blow up just 300 feet off the ground and the pilot was not hurt.

'Lo Night
Sterno cooking fuel is a jellied alcohol product and
relies on atmospheric oxygen to burn. You can put it out by shutting off
the air, as you indicate. But solid rocket fuel incorporates its own
oxidizer. And therein lies the problem of how to throttle it or shut it
down once it's lit.
BTW, the batwing plane was so named by my ladyfriend
Lottie, who says it resembles a bat in flight. She used to fly gliders
in Germany and is also an aviation buff. oc

It's obvious Bert Butt'o'rack doesn't have a clue about solid rocket
engines.

Correct Officer Bert liquid fuel provides better control for the
pilot and the choice of Dr. Von Braun and he was not permitted to
further research cell fuel stacking of solid fueled booster rockets. A
combination could be envisioned rather then total support on just
convention full body solid fuel booster rockets. Another reason for his
departure no doubt was the absent crew escape Nasa choice design of the
space shuttle now admitted error.

Hi oc All fuels need oxygen to burn(other than nuclear) Bombs go off
under water(depth charges. Chemical with lots of oxygen molecules in its
structure burn "salt peter" The Chinese knew this 5,000 years ago.
Saturn V had 5 liquid rockets(burning liquid oxygen). Von Braun had the
astronauts lives come first. NASA shuttle could only kill,as proven by
the Challenger. The explosion did not kill them(this was proven)
Hitting the water killed them. Bert
