Description
What kind of engine does a turboprop engine use?
Propellers are very efficient and can use nearly any kind of engine
to turn the prop (including humans!). In the turboprop, a gas
turbine core is used. How does a turboprop engine work? There are
two main parts to a turboprop propulsion system, the core engine
and the propeller.
Turbo Maintenance
One thing all turbos need to survive is good lubrication and
cooling. The turbine and compressor wheels are mounted on a shaft
that is supported by water-cooled bearings in a center housing. The
bronze shaft bearings are pressure lubricated and must have a
steady supply of oil to handle the high shaft speeds. Synthetic
oils are best for turbos because they can handle higher operating
temperatures. Regular oil and filter changes are also essential to
prevent viscosity breakdown, varnish deposits and sludge that can
damage the turbo’s shaft bearings.
Turbo Troubles
The most common problem with high mileage turbos is bearing wear,
although blade erosion can also be an issue if the vehicle has an
ill-fitting, damaged or missing air filter. Turbine wheel damage in
the turbo housing can also occur if an engine has had a valve or
piston failure and shrapnel exited an exhaust port.
Noise such as whistles or hisses can be caused by air leaks in the
turbo housing, connections or plumbing. Squealing or scraping
sounds can be caused by bad shaft bearings or the wheels inside the
turbo scraping against the housing. Oil inside the compressor
housing would tell you the shaft seals are leaking.
Bad turbo shaft bearings can reduce turbo speeds and boost
pressure, or they may cause the turbo to stop spinning altogether.
A good turbo should spin freely with no drag, scraping or noise
when spun by hand. Any wheel-to-housing interference will create
drag and prevent the turbo from reaching normal speeds.
