Peroxide would be really cool if you could use induction heating to get
it to self catalyze safely. There by avoiding the cat packs completely.
But right now I just need a motor I can use to test the pumps with. I
am now confident the pump test stand I'm working on will do the job. I'm
also confident I can start testing pump designs as soon as that is
finished hopefully by February end.
The test motor must be biprop and therefor cat packs and flame
holders.The only thing I want special is symmetric burning and good
clean combustion. (who wouldn't? lol)
The plan is to have it together and ready for a first fire by April
end. Pump development should begin and the motor should also begin
development along side.
30 years ago I was going the other way disabling biprop mode on a gama
engine for a peroxide dragster. Damn I wish I still had access to that
motor. (yeah, perhaps I can find it?)
Paul, looks like we will buy a container at FAR this year. I've had a
talk with Kevin Baxter and we are going to need peroxide storage too.
You are going to see amateur turbopumps very soon. I've found my niche'
This is what I was born to do I thought it was rockets but now I know
it's a specific part of a rocket.

For a flight weight vehicle, its hard to build light weight LOX tanks, and
the valves for LOX are a continuous problem with
small valves.
Also if you factor in the price of Helium I think that peroxide pressurized
with Air or N2 is lower cost than LOX.
The Lox is almost free, the Helium not so much....
Also no hardstart issues, it just lights....
the O:F is ~ 7:1 and the O is the coolant for Regen, small Lox hydrocarbon
regen motors are hard and need film cooling,
with Persoxide I'm runing a 100lb regen aluminum motor with no cooling
issues (so far)
You do have cat pack issues...
You can get you oxidizer and store it for log periods... not so with Lox.
I like peroxide....

Where there some details somewhere? Yeah, I think Paul had a better
source for peroxide than Armadillo seems like a lot of Armadillos work
was done with lower concentrations at least on the bigger motors.
Peroxide/gasoline or kero would seem to benefit from jet engine
technology. Basically treat it like a jet ingesting a lot of water. I
wonder if an annular combustion chamber can be made to withstand the
heat?
That would be reinventing the wheel right now which I'm wanting to
avoid.

Check out Paul Breed's peroxide/gasoline engine that flew on one of his
"lander challenge" vehicles: that seemed to be a smooth-running unit
(though well under the 1000 lbf. you contemplate here).
