Core Alert takes engine health data
and plots trends of several performance
parameters. These data, which are
captured automatically, now follow a
large number of parameters compared to
the traditional manual systems. The large
number of parameters now followed
allow problems that are developing to be
pinpointed down to a module level. This
can even allow smaller shop visits to be
performed, or repairs and maintenance
that prevents full shop visits.
Performance data are summarised for
operators, and predictions such as EGT
margin reaching zero are also made. This
timing is also compared to LLP lives, and
so decisions about optimum timing of
removal for shop visits or overhauls can
be made.
Airline customers thus sub-contract
engine health monitoring to DS&S, but
because the system is web-based airlines
can still monitor their own engines. This
allows DS&S to liaise with customers and
consult them about the management of
their engines. Engine health monitoring
data used by DS&S can either come
directly from the customer airline or RR’s
24/7 operations room.
In addition to plotting trend data,
Core Alert also provides alerts to
customers by text messages, e-mails and
other formats.
The combined services of RR’s 24/7
operations room and DS&S’s Core Alert
provide airlines with an operations
management management service for
engines.
Data are monitored and collected 24
hours per day, seven days per week,
including data captured during take-off,
climb, cruise, descent and landing phases
of flight. Sub-contracting this function to
RR and DS&S allows airlines to avoid
investing in in-house capability while still
maintaining compliance with all
regulatory requirements. Technical
problems can also be anticipated,
preventing in-service delays and
expensive unscheduled maintenance
visits. Scheduled removals and engine
maintenance can also be optimised. This
allows lower cost per FH to be achieved,
as well as preventing clusters of removals
that result in peak demand for spare
engines.
In greater detail, Core Alert can
detect, among other technical issues, inservice
problems relating to high pressure
turbine system deterioration, compressor
damage, fuel and nozzle coking, faulty
bleed valves, sensor errors, foreign object
damage and bearing distress.
Core Alert also has an intelligent
diagnostic system that can pinpoint likely
causes of alert notices sent to customers.
Trend charts are generated automatically
and kept up to date, and data can be
analysed and displayed in a number of
ways. Fleet summaries can also be
provided, so that fleet status information
of deterioration and EGT margin status
can be provided.

Jouve’s AirGTI has the facility to search for a part
with a word search. Once a picture of the part is
retrieved, the IPC shows an item number. This
item number is used to find the part number.
MAGNETIC PARTICLE TESTING
MT - MAGNETIC PARTICLE TESTING
DESCRIPTION OF THE METHOD
MT is often used as nondestructive testing of ferromagnetic materials. The major applications are in aircraft and automotive industry,
in power industry and transportation. With regard to its relative simplicity and low demand for carrying out, it is one of the most important
methods even for inspection of equipment in service. MT is capable to detect surface and subsurface defects such as tears, cracks, pores,
inclusions and the like of ferromagnetic materials. It is not applicable for other materials than ferromagnetic ones.
