We have some rough numbers for the pumps.
Going with Lloyd's numbers because the same numbers are close for the
Barsky as well.
Fuel Pump
Mass Flow = 0.89 lb/s
DP = 870 psi
N = 50 kRPM
Inlet Diameter - 0.40"
Outlet Diameter - 1.72"
Inlet Height - 0.23"
Outlet Height - 0.033"
Inlet Angle (Beta1) = 9deg
Outlet Angle (Beta2) = 20deg
#Blades = 12 (6 are half length)
Outlet Flow Angle (for Volute tounge) = 4deg
Shaft Diameter = 0.15"
Input Power = 9.4 kW
Oxidizer Pump
Mass Flow = 6.23 lb/s
DP = 940 psi
N = 50 kRPM
Inlet Diameter - 0.79"
Outlet Diameter - 1.40"
Inlet Height - 0.165"
Outlet Height - 0.072"
Inlet Angle (Beta1) = 9 deg
Outlet Angle (Beta2) = 25 deg
#Blades = 8 (4 are half length)
Outlet Flow Angle (for Volute tongue) = 11.2 deg
Shaft Diameter = 0.25"
Input Power = 26.2 kW
I am now working on the test stand that will power the pumps and I am
satisfied I can reach the project goals with the test stand.
I'd like to see if we can get the guy's that helped me start this
project back together and talk about a test engine.
We can integrate the engine stand with the pump test stand and use one
data ack system.
The test stand for the pumps has a large V-8 engine for power and is
self contained I'd like the engine test stand to also be self contained
perhaps the pump test stand can share some systems with the engine test
stand?
The ultimate goal for me is to run the engine for 5 min at full power.
My time table is first pump test in February and I'd like to have an
engine ready for testing I'd like to be running some test firings of the
engine (pressure feed not pumped) before April.
I'd like to have 2 modules that fit together.
The test stands and support equipment (tanks ect) must be transportable.
Because there are good people at FAR that would probably like to see
this work I'd like to be able to test there.
