NOTE 5. Engine ratings are based on calibrated te st stand performance under the following conditions:
- Static sea level ISA conditions, (59 F, 29.92 in.Hg.)
- No air bleed
- No power off-takes by the accessories.
The ratings are minimum acceptable final test performan ce of series and overhauled engines, measured with:
- Calibrated test bed air intake, according to Turbomeca dwg. No. 6202 66 701 0.
- Flight exhaust pipe, Turbomeca Part No. 0.249. 76.000.0 (which is part of engine delivery).
- Air intake anti-icing protection shield installed, but not supplied with hot air.
NOTE 6. Maximum permissible air bleed (from centrifugal compressor plenum).
(Orifice limited at engine ou tlet with 0.598 in. orifice).
- For aircraft services (including inlet duct anti-icing when required) 0.397 pounds per second.
- See Turbomeca Operation Manual for limitations on bleed flow vs engine power and r.p.m.
NOTE 7. Air intake anti-icing limits:
- If OAT is between +5 C and -20C, Gas Generator r.p.m. must be equal to or higher than 26,000
- If OAT is between -20 C and -30C, Gas Generator r.p.m. must be equal to or higher than 26,500
- Also engine oil temperature must be equal or higher than 30 C.
