Beschreibung
Zusammenfassung:	A gas turbine engine (10) comprises carbon fibre fan blades (230). At cruise conditions, the fan tip air angle θ in the range: 64 degrees ≤ θ ≤ 67 degrees. Additionally or alternatively, the fan blade tip angle β is in the range of from 62 to 69 degrees. Arrangements in accordance with the present disclosure provide advantages which may include improved bird-strike performance. This may allow advantages associated with carbon fibre fan blades to be better exploited.
