The WALTER M601 is a two-shaft turboprop engine of reverse flow layout. The
engine features two basic parts: the gas generator and power section. The gas
generator consists of two stage axial and one stage centrifugal compressor,
annular combustor and one stage axial turbine. An accessory gearbox with
instruments necessary for engine operation and power control is situated on the
rear part of the compressor air intake casing. An oil tank is an integral part
of the accessory gearbox. The power section is mounted on the front part of the
gas generator. This section consists of one stage axial turbine, exhaust system
and two stage reduction gearbox with a torquemeter and propeller shaft. The
propeller governor is situated on the reduction gearbox and provides the control
of the hydraulic actuated propeller including the reverse thrust angle
adjustment.
The engine is equipped with a system of electronic limiters
which protects the engine against overload. The engine is modified for
installation of automatic feathering system.
