Fonsini,
The figures related to an engine failure after take-off for a Meteor variant that I have flown that has the big fin and rudder and Derwent 9 engines:
Unstick was 120 - 130 KIAS. If an engine failed below 130 KIAS the only option was to close both throttles and land straight ahead (or eject!). Following an engine failure between 130 and 165 KIAS, power had to be reduced on the good engine in order to maintain control using rudder and aileron, and once control had been regained full power was re-applied to accelerate to and then climb at 200 KIAS which was the best single engine climb speed. As much rudder as possible was applied (typically the forces were too high to achieve full deflection) and then 5 - 10 deg of bank towards the live engine was also used to help maintain straight flight. With the gear and flaps up a rate of climb could be achieved at 135 KIAS and above. 165 KIAS was defined as 'safety speed' and an engine failure at or above this speed could be controlled without reducing power.
