Our Model 56S is designed to mount directly to Solar Saturn engines.
An integral soft clutch eliminates the jaw-type clutch assembly, for
trouble free operation. And because the 56S motor requires no
lubrication in the drive air…fugitive starter exhaust emissions can be
totally eliminated.

TDI
TURBOSTART
Model 56S
INDUSTRIAL GAS TURBINE STARTER
The TDI TURBOStart Model 56S turbine powered starter motor is designed for application
to Solar Saturn gas turbine engines. The Solar Saturn industrial engines are widely
used for electrical power generation, industrial drives, and marine propulsion. The
Model 56S was designed as a replacement for both the vane-type starter motor and the
over-running and/or pneumatically driven jaw clutch assembles. The 56S has a
mounting flange and output shaft spline that mates with the accessory drive assembly
starter mount pad.
The 56S uses a robust turbine drive motor design. Properly installed, the turbine motor is
highly resistant to damage caused by wet or hard contaminates in the drive air/gas.
APPLICATION
VERSATILITY
CONTAMINATED
SUPPLY AIR/GAS
The Model 56S-07 starter can be used over a wide range of drive pressures from 80
psig (6 BAR) to 150 psig (10 BAR). It is suitable for operation on either compressed air
or natural gas. On air it delivers 47 HP (35kW) of cranking power at 150 psig (10 BAR)
with only 790 scfm. The starter materials have been selected to be compatible with
“sour” natural gas and marine environments. For installations having less than 80 psig
operational drive pressure at the starter inlet, low pressure versions can be ordered
through your local TDI representative.
LOW AIR
CONSUMPTION
The Model 56S provides significantly lower life cycle costs when compared to both the
acquisition and operating costs of aviation derived starters. For industrial turbine engine
application, the Model 56S provides superior performance and reliability at substantial
savings over other starter alternatives.
LOWER COST
The starter can be operated using compressed air or natural gas pressures up to 150
psig (10 BAR). The 56S produces up to 140 HP on natural gas. See performance data.
CRANKING POWER
The Model 56S starter incorporates the TDI low mass turbine rotor designed to fracture
in a precisely engineered and inherently safe manner should the starter ever over
speed.
The Model 56S features an internal (vented) oil sump, which functions as a stand-alone
method of starter lubrication. The Model 56S also provides pressure lubrication ports
which permit optional extension of the engine oil system to facilitate starter lubrication.
This option is preferred by some operators when using the Model 56S.

An axial flow turbine coupled to an integral planetary gear reduction set powers the
Model 56S starter. The turbine power combined with the planetary gear reducer results
in a very efficient and compact unit. The Model 56S incorporates a sprag type
overrunning clutch in the starter gearbox drive train to provide a means of disengaging
the starter from the gas turbine engine once the starter cutout speed has been reached.
The Model 56S starter can be operated using either compressed air or natural gas.
Tech Development Inc. introduced the first turbine technology for starting industrial
engines in 1979. The TURBOStart 56 series air starters feature an innovative and more
reliable turbine motor than any other gas turbine starter on the market today. The 56S is
the result of TDI’s continuing turbine starter design innovations.
