Thrust vectoring
Subject: Thrust vectoring
From: (JAXAshby) Date: 03/25/2004 13:57 Pacific Standard Time Message-id: t can also be applied to moving ahead, no, it can not. water *pushed* over a rudder can cause a rudder to turn a boat, while water "pulled" over a rudder can not. Jax, quit worrying about push and pull. Take a sailboat and start backing it with the engine.... get up the right amount of speed and shut down the engine. You can now steer that boat because of the forces of the water PASSING over that rudder, exert a steering force. Hoist sails and trim them to start getting headway (you are not pushing water over the rudder you are passing water over the rudder) and once you have sufficient speed, this water passing over the rudder will exert a force to steer the vessel.... hence it applies astern or ahead. Too simple for you to understand? ...... oh well...... Shen |
