Analysis of Aerothermal Environment Characteristics of Hypersonic Rudder Shaft Gaps

气体物理
Rudder shaft gaps of hypersonic vehicles affect the flow structure and corresponding aerodynamic heating characteristics, resulting in local peak heating near the rudder shaft, which poses a safety risk to the local thermal protection system.

A new energy saving twin rudder system - Gate Rudder [PDF]

, 2015
Rudder and propeller of a ship share almost similar long service history. The rudder is usually placed behind the propeller to make use of the strong slipstream flow of the propeller. By changing the direction of the slipstream flow the rudder functions as a remarkably effective control surface to maneuver the ship.
