This video explains how the hydraulic twin servo system controls the position of the Inlet Guide Vanes (IGV) and Variable Stator Vanes (VSV) in a gas turbine. It begins with the physical layout of the hydraulic pump and twin servo assembly and introduces the closed-loop control concept used to position the blades accurately.

The video then breaks down the operation of the torque motor and shuttle, or spool, valve. You’ll see how the turbine control system uses a 0–200 mA signal, with 110 mA as the null position, to balance or shift control pressures on either side of the spool valve.

Using a practical example, the video shows how small changes in control current create pressure differences that direct hydraulic oil to extend or retract the actuator. Finally, it explains how position feedback returns the system to a neutral, stable condition once the desired blade angle is reached, ensuring precise and repeatable vane control.

ARTICLE REF – ART262

“This video looks at a real-world reliability issue on FT8 gas fuel systems — the flexible fuel injector hoses.

Early FT8 turbines used rigid stainless-steel tubing between the gas manifold and the fuel injector. Those lines took longer to install, but they were extremely robust.

Around 2012, Pratt & Whitney changed to a flexible hose design. In gas-only service these hoses generally perform well — but in dual-fuel units that also operate on liquid fuel, a serious failure mode has emerged.

These hoses use a thin, bellows-type metal inner tube, reinforced by an external stainless-steel braid. The braid is not cosmetic — it provides most of the strength. If that braid is compromised, the hose can fail very quickly.

What we see repeatedly is cracking right at the end fittings — and that is exactly what you are looking at in these photos.”

This video explains how power turbine cooling air and thrust balance airflow control axial forces on the power turbine rotor. Cooling air flows through the LP turbine and bearing areas before exiting through seals and mixing with exhaust gases, generating an aft axial force as energy is extracted. The number eight bearing absorbs part of this load, while Power Turbine Thrust Balance (PTTB) air provides an opposing force. Proper sealing is critical to prevent pressure leakage and ensure effective thrust balance. The video also introduces troubleshooting and seal-condition evaluation methods not covered in manufacturer documentation.

Solar Mars Shaft Alignment: 

Learn Solar Mars Shaft Alignment:
This video teaches you how to align the shafts on a Solar Mars hot-end drive. Proper alignment is necessary so that the shaft center lines are perfectly superimposed (lined up) while the machine is running at normal temperatures.

Why do we misalign the shafts when they are cold? When the turbine runs, it gets very hot and the metal expands. The compressor does not heat up as much as the power turbine. Also, the back (aft) of the turbine gets much hotter than the front. To make sure the shafts are straight when the machine is hot, we must intentionally misalign them while they are cold.

How to fix alignment errors: In this setup, we always move and shim the turbine relative to the compressor.
• Looking from above (Horizontal): If the shafts are not lined up or not parallel, you must loosen the turbine bolts and slide the machine to the side. No shims are needed for these side-to-side adjustments.
• Looking from the side (Vertical):
◦ If the faces are parallel but one shaft is lower, you must add an equal amount of shims to the front and back of the turbine to lift it up.
◦ If the faces are open at the top (not parallel), you must use different amounts of shims at the front and back supports.

What you will learn: This training focuses on the math and calculations needed to find the exact shim thickness for the front and back supports. Mastering these steps will ensure your equipment runs smoothly and stays in parallel. 
 

Compressor Cleaning: 

 

This video explains how to perform ingestive cleaning on a Solar Mars turbine. This process removes dirt and salt from the compressor blades and stators. When these parts are dirty, the airflow becomes turbulent, which reduces the turbine’s power and efficiency,.

Two Ways to Clean There are two main methods for cleaning the compressor:
• On-crank cleaning: This is done while the turbine is shut down and cooled. It is the most effective way to remove stubborn dirt.
• Online cleaning: This is done while the turbine is running at normal speed. It helps recover power without stopping the machine.

The Cleaning Process For a successful on-crank wash, you must follow these key steps:
1. Cooling: The turbine must cool for about 8 hours until the casing temperature is below 65°C,.
2. Preparation: You must remove the 11th stage bleed lines and install blanking plates to prevent the cleaning liquid from leaking.
3. Using the Wash Cart: A 100-liter wash cart holds the cleaning detergent or water. This liquid is injected into the air intake through special manifolds,.
4. Detergent and Rinsing: You can use approved detergents for oily dirt or water for salt and dust,. You must always rinse with water after using a detergent.

Borescope Inspection:

 
A borescope inspection is one of the most important tasks for a maintenance technician. It allows you to look deep inside the Solar Mars turbine without taking it apart. This video provides a clear guide on how to perform a standard inspection, helping you find hidden problems before they become expensive failures.
 
Why Borescope Training is Essential for a new technician, looking inside a turbine can be intimidating. There are 32 borescope ports and many other inspection locations to manage. This video teaches you how to navigate these areas safely so you don’t get your equipment stuck or cause damage that requires the turbine to be sent back to the factory.
 
What the Video Covers
 
• Navigating the Turbine: Learn how to enter from the front air intake to inspect the first stages of the compressor.
 
• Correct Naming: We explain the difference between parts like the IGV (Inlet Guide Vanes) and VGV (Variable Guide Vanes). Using the right names ensures your reports are professional and accurate.
 
• Finding Faults: Learn what to look for, such as oil leaks, cracks, or impact damage from foreign objects.
 
• Advanced Access: We show you how to use special tools, like guide tubes, to reach the combustion chamber and the first-stage nozzles.
 
By mastering these basics, you will have the confidence to inspect any turbine. You will learn to identify common defects like erosion, burning, and corrosion, ensuring your equipment stays safe and reliable.
