The method of protecting the engine against damage (leaks, unstable operation) and determining the engine’s service life and durability are presented. Selected problems and faults occurring during engine operation are also discussed. ENGINES PZL-10W – ASPECTS OF MAINTENANACE The article discussed some aspects of maintenance PZL-10W engines. Characterized the primary engine fuel control system and modernized. Presented how to protect the engine from damage (leaks, unstable work) and the findings of the resources and the durability of the engine. Also discussed some problems and faults that occur during using the engine.
1. INTRODUCTION
The PZL-10W turboprop engine forms the basis of the propulsion system for the W-3 “Sokół” helicopter.
This helicopter is widely used − both in military and civilian versions. The PZL-10W engine, as a version of the TWD-10B aircraft engine adapted for the helicopter, has been in operation since 1986, when serial production was launched in Rzeszów. Years of experience have allowed for a thorough understanding of this design, as well as its development and modernization, which will likely allow for many more years of operation.
The entire population of PZL-10W turbine helicopter engines can be conventionally divided into several design stages and associated operational methods.
The first group of engines, series 1 and 2, introduced into service in the initial period of the helicopter’s operation, had a time-limited hourly service life − 750 hours/1125 cycles, successively extended after the implementation of subsequent bulletins to 1000 hours/1500 cycles and 1500 hours/2250 cycles. The calendar life, initially 5 years, was also extended to 6, 7, and 8 years of operation and storage.
The second group of engines – series 3, produced since 1997, meeting the requirements of FAR-33 regulations, colloquially referred to as “FAR” engines, underwent a series of modernizations and achieved an overhaul interval of 3000 hours. (…)
