b. SPECIAL TOOLS. The client shall provide, on loan, specialty tools required in removing turbine wheels of the T55-GA-714A turbine engine if required.

5. CONTRACTOR FURNISHED ITEMS.

a. PERSONNEL. The contractor shall furnish fully qualified and certified personnel to perform contract and PWS standards.

b. FACILITIES. The contractor will provide space for the client to store the engine at the contractor’s facilities before the project begins and after the completion of the project until the client takes delivery of the engine.

c. TOOLS AND EQUIPMENT. The contractor shall provide all equipment, materials and any ancillary work indicated and/or specified for performing the requirements pertaining to project.

6. SPECIFIC TASKS. To accomplish this objective the following sections of this Statement of Work, and the provided drawings, the Contractor shall:

a. ENGINE ASSEMBLY SECTIONAL CUTAWAY. A portion of the engine assembly shall be cutaway to expose the internal rotating assemblies and subassemblies. The cutaway section will be from 12 o’clock and end approximately at the 7 o’clock position (be sure not the cut below the forward engine mount), as viewed from behind, running the length of the engine assembly (see figure 3). The cuts, at their respective clock positions, shall extend inward at a 90° angle as to intersect the center of the engine. Furthermore, the 8 o’clock position/entry point of the diffuser and combustion housing shall be cut and layered as detailed below.

b. AIR-INLET HOUSING. In addition to the sectional cutaway of the air-inlet housing’s exterior frame, the oil reservoir and power output shaft housings will also be sectioned using the same entry points and linear plane cut lines as indicated above for the engine assembly. The principle purpose behind these cutaway sections is to expose the power output shaft and torque metering head (see figure 4 for details). Paint the interior walls of the air-inlet (air flow path) blue, see figure 1.

c. COMPRESSOR HOUSING. In addition to the sectional cutaway of the compressor housing halves, cut the bleed band actuator band, which wraps around the housings, along the same entry points as compressor housing halves and the loose ends secured to housing. Paint the interior wall and stator vanes of the compressor housing blue, see figure 1.

d. DIFFUSER HOUSING AND COMBUSTION HOUSING. Make the standard sectional cut at the 12 o’clock position. A modified sectional cut at the 8 o’clock position is required. The client desires to retain the existing conceptual layered flow design of the diffuser, diffused vanes, combustion housing, and combustion liner; however, it will need to be lowered to begin at the 8 o’clock position so as to expose more of the turbine section. The layered sections should be staggered vertically by approximately 2 inches converging around the igniter plug. The combustion liner should converge above the igniter plug with one exposed swirl cup and fuel nozzle. The principle purpose behind these cut modifications is to expose more of the turbine sections and retain the igniter port and starting fuel nozzle. The curl plate’s existing bottom cut will also need to be extended to 8 o’clock position (see figure 5).

e. TURBINE SECTIONS. In addition to the sectional cutaway of the turbine housings/assemblies, the turbine nozzles’ will need their outer frames cutaway to expose the stator vanes underneath (see figure 6). The 3rd stage turbine nozzle will need welding of the vanes to the hub.

f. HYDRO-MECHANICAL ASSEMBLY (HMA / “fuel control assembly”). The HMA shall have sections cutaway to expose as much of critical internal component without losing any structural integrity. The provide paint marking will give a relative idea for entry/cutaway sections (see figure 10).

g. ANIMATION. The engine requires two electric motors to drive the N1 section (blue) counter clockwise and N2 section (red) clockwise at different speeds (see figure 8). To highlight key areas use RBGW (red blue green white) LED lighting (see figure 9). Based on the T700 engine, more or bright light are required to see in well-lit classrooms. Internal lighting Highlight scheme: LED light scheme will have 4 settings: 1) All white, 2) Color scheme (white-to-blue-to-orange-to-red), 3) Flashing color scheme (white-to-blue intake process), and 4) Flashing color scheme (intake to orange-to-red combustion process). The electrical control/switch box will be mounted externally, front and centered. The electric system must be 110 vac standard service outlet compatible.

h. MOBILE DISPLAY STAND. Construct a rolling mobile display stand similar to the stand for the T700 engine project. The display must also include a low profile contouring Plexiglas protective covering of the engines internal rotating assemblies similar to the T700 engine. The stand must be no wider than 34 inches, allowing it to fit thru a standard door. The overall height of the display (top of the engine) should not be taller than 60 inches. The mobile display stand should house the components to drive the internal rotating gas producer section and power turbine section of the engine and be controlled by separate switches to operate each section of the engine independently.

i. PERIOD OF PERFORMANCE. After the contract has been awarded and the contractor has taken delivery of the engine work will began immediately and project completed in 150 day.

j. MONTHLY UPDATES. Contractor shall keep the client informed on a monthly basis of the projects progress, including picture, via email.

7. CONTRACT DISCREPANCY. A failure of the contractor to perform in accordance with contract requirements and specifications will result in a contract discrepancy. A contract discrepancy may result from a failure of the contractor to provide, or provide on time, the required contract products or services; or it may result because delivered products or services do not meet contract standards.
