For “Mid” and “Large” class jet engine starting, the air turbine starter is used to reduce weight than electric starter (motor).
Air starter is drive by pressurized air supplying by APU or ground equipment.
There are “Radial” or “Axial” type of turbine. This is “Axial” type running model by the home vacuum cleaner as the source of power.
The features are as follows.
① Axial Turbine Rotor and Stator
② Two Stages of Planetary reduction gears (Reduction Ratio 10:1)
③ One-way Clutch (Simplified)
④ Output (Quill) shaft
⑤ Metal bearings are used for all the rotating shafts.
⑥ This can be dis-assembled and assembled.
⑦ The vacuum nozzle with the variable opening for speed control.
"Over-speed Switch” and “Oil Pump”having by the actual Starter are eliminated for this model.
Maximum allowable RPM and torque are not verified. Please decide by self-responsibility.
B. Assembly Manual (PDF format, total 17 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)".
In order to make it rotate smoothly, careful eccentricity and gap adjustment are needed.
