Turbine Warlock Project

[John Hice]

Made some pretty good progress on the project this weekend. I have only three more runs of 10awg wire to run for the cooling fans and the fuel supply pump. Run out of wire today.



In this pic is the starboard battery main disconnect solenoid, the solenoid controller in the middle that only supplies enough voltage to the large solenoid to keep it engaged depending on the draw going through it which keeps it from getting hot in upwards of 180 degrees. The smaller solenoid is to engage the alternator. I found if you connect the alternator as you would on a normal engine it starts to charge when the turbine gets to 15% and puts much more strain on the turbine starter and increases the EGT on startup. Yes, I could have changed the regulator in the alternator to a non self exciting regulator but I prefer to cut all power to the alternator. I just like it that way!


This is the port main battery and battery disconnect that's controlled by the same controller on the starboard side. The very large solenoid is the series parallel start solenoid to supply 24 volts to the turbine starter and of course an on-board charger to keep the batteries maintained when the boat is in storage.


Few pics of the helm and cockpit area. The seat is just setting in place so I could make a few imaginary passes and collect my thoughts.






This is in the spacious machinery compartment "No It's Not Spacious" on the starboard side just in front of the pilot. Mounted on the bulkhead is the fuel lift pump supplying fuel to the turbine at 4 psi and up to 200 gallons per hour. Attached to the lift pump is a primary Racor filter with a PMOR 2040 30 micron pre-filter before the fuel goes into the lift pump and the secondary 3 micron filter on the pressure side of the pump before it goes on to the turbine.
In between the pump and the filter is the brake master cylinder with a remote mounted reservoir for the N2 turbine brake for putting the crash-box in and out of forward and reverse.


This is in that same compartment on the port side just ahead of the insane co-pilots seat. From left to right is the gearbox oil filter, gearbox oil reservoir, engine oil reservoir and ahead of that is the fuel to oil cooler for the engine.
The engine oil heat is exchanged with the cool fuel thus cooling the engine oil and heating the fuel for a better automation of the fuel going into the combuster of the turbine.
