2.1.1 At least
three copies of the following plans are to be submitted.
- Sectional assembly.
- Casings.
- Combustion chambers and heat exchangers.
- Rotors, bearings and couplings.
- Blades and blade attachments.
- Inlet and exhaust ducting.
- Securing arrangement (including details of resilient mounts where
applicable).
- Control engineering aspects in accordance with Pt 16, Ch 1 Control Engineering Systems.
- Fuel oil system schematic, including controls and safety devices.
- Lubricating oil system schematic.

- Cooling water system schematic, where applicable.
2.1.2 The following
information and calculations are to be submitted.
-
Details of the acoustic
enclosure fire detection and extinguishing system, where applicable.
-
Power/speed operational
envelope.
Calculations and information for short term high power operation,
where applicable.
Operation and Maintenance Manuals.
-
Calculations of
the critical speeds of blade and rotor vibration, giving full details
of the basic assumptions.
An analysis of the effect of a rotor blade failure and any details
of service experience, see
Pt 10, Ch 2, 4.3 Containment.
-
High temperature
characteristics of the materials, where applicable, including (at
the working temperatures) the associated creep rate and rupture strength
for the designed service life, fatigue strength, corrosion resistance
and scaling properties.
Particulars of heat treatment, including stress relief, where
applicable.
Material specifications covering the listed components together
with details of any surface treatments, non-destructive testing and
hydraulic tests.
2.1.3 The most
onerous pressures and temperatures to which each component may be
subjected are to be indicated on plans or provided as part of the
design specification.
2.1.4 Calculations
of the steady state stresses, including the effect of stress raisers,
etc. in the turbine and compressor rotors and blading at the maximum
speed and temperature in service are to be submitted. Such calculations
should indicate the designed service life and be accompanied, where
possible, by test results substantiating the limiting criteria.
2.1.5 Details
of calculations and tests to establish the service life of other stressed
parts, including gearing (where applicable), bearings, seals, etc.
are also to be submitted. All calculations and tests should take account
of all relevant environmental factors including particular type of
service and fuel intended to be used.
2.1.6 Components
fabricated by means of welding will be considered for acceptance if
constructed by firms whose works are properly equipped to undertake
welding of the standards appropriate to the components. Details are
to be submitted for consideration.
2.1.7 Before
work is commenced, manufacturers are to submit for consideration details
of proposed welding procedures and their proposals for routine examination
of joints by non-destructive means.
2.1.8 The manufacturer's
proposals for testing the gas turbine are to be submitted for consideration.
