Vertical/short take-off and landing - LIFT THRUST AUGMENTATION

23. In many cases on V/STOL aircraft augmentation of the lift thrust is necessary to avoid an engine which is oversized for normal flight with the consequent effects of higher engine weight and fuel consumption than would be the case for a conventional aircraft- This lift thrust augmentation can be achieved in a number of different ways:
(1) Using special engine ratings.
(2) Burning in the lift nozzle gas flow.
(3) By means of an ejector system.
