> Most of them are far more subtle that a Harrier like vectoring of exhaust gas. The Harrier has a number of bleed air reaction nozzles dotted around the aircraft so it can be controlled whilst hovering. The vectored thrust is just for the main "drive", these nozzles replace the control surfaces at hover speeds. https://xplanereviews.com/index.php?/forums/topic/965-aircraft-review-mcdonnell-douglas-harrier-av-8b-by-x-trident/ https://xplanereviews.com/index.php?/forums/topic/965-aircra... > For me the significant area was the flight "puffer" small reaction nozzles that are the most important and the most ingenious aspect of the Harrier. It is actually quite easy to support any aircraft on a downward thrust of gases, and even here with the clever engine mounted vector nozzles... the real trick was in actually controlling the aircraft in the air. The Harrier has a unique system of engine bleed that directs air to the various reaction nozzles...
