Engine Programs
The Walter M601E-11 was originally designed to match
Russian conditions of heavy climate and lack of qualified engineers on site.
This is why the engine is specific by its install-and-go philosophy. This
means there are no "hot section" inspections, as with other
products. These excellent features are making M601 more and more popular
outside the original target market. The reason the engine is not of modular design (but
very rigid and heavy duty and is the reason why no complicated on spot
repairs are supposed to take place). In fact there is no "On-Condition"
maintenance scheme necessary and is actually not possible for technological
reasons. There is only basic maintenance during TBO if everything is OK. So
an engineer with no special experience is able to do all the maintenance
himself after passing a 1 Week course in "WALTER". This is why this
engine has attracted even non-professional flyers. The TBO of WALTER M601E-11 is limited by whichever
occurs first of the following: 1.
Cycles: from 2,250
to 20,000 cycles OR 2. Flight
Time: 2,000 or 3,000 hours or; 3. Calendar
Time: 8 years |

M601 Turbo Prop Engine
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
torque meter 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.
