At the end of WWII, the only manned tailless fighter equipped with a liquid rocket engine was developed and produced in Germany (Me163), and remodeled and prototyped in Japan (秋水).
In Japan, the war ended shortly after the failure of the first flight, and it ended incompletely.
The engine uses the propellant (below) that self-ignites by mixing fuel and oxidizer.
・Fuel(C-Stoff, 乙液: "Hydrazine (30%) + Methanol (57%) + Water (13%)",
・Oxidizing agent(T-Stoff, 甲液): "80% hydrogen peroxide solution"
Both were dangerous chemical that were difficult to handle because they were powerful drugs.
The engine names are known as HWK109-509A (Germany), 特呂二号(Japan).
The main components are
[A] Power unit (Turbopump, Gearbox, Starter),
[B] Combustion Chamber (Injector, Combustion Nozzle, Cooling Device),
[C] Metering Unit, [D] Steam Generator, [E] Steam Control Valve, etc.
This time, I made a functional cut model teaching material for “[E] Steam Control Valve” with reference to books and public information on the Internet.
A. Features of this model (Steam Control Valve)
① Selector Valve and Lever (Select ports of T-stoff supplied from Metering Unit)
② Idle Control Valve (Control Idle Pressure and Flow of T-stoff)
③ Safety Valve (Limits Excessive T-stoff Pressure from Metering Unit)
④ Color identification (Light Green: Fuel, Yellow: Oxidizer, light blue: Steam)
B. Assembly Manual (PDF format, total 7 pages)
The detail assembly manual including "Parts-List", "After printing treatment" and "Assembly procedure" are prepared based on "Standard Skill (Filing, Drilling, Tapping and painting)".
C. Purchase Parts Information;
1. Screws
M1.4, M2, M3 - You can adjust quantity and size of screws.
2. AL Pipe - φ3
3. Coil Spring - φ0.5x7.9x28.7 - Similar parts is acceptable
D. STL file
Total STL files are 16 items including the stand and tools.
“ws” of last 2 digits of file name means “With Support” special designed.
E. Total Net Print Time: Approx. 10 HR
- (Estimated as case of PLA, 0.4mm Nozzle, 0.2mm Layer Height, 40% infill and No raft and support)
Note: When at actual print, each parameter may be adjusted by your experience.
F. Printing settings
Raft, Support, Layer Height, Infill: Depending on your experience.
My models were printed by "idbox" using with 0.4 nozzle, 1.75 PLA.
I do hope your success!!
