Rudders

Footage shows orcas repeatedly targeting boat rudders in the Strait of Gibraltar.

This set features all the real-life engineering details of the actual Concorde, including a tiltable droop nose, a retractable tail bumper wheel, delta wings with movable elevons, hinged upper and lower rudders, and functioning landing gear.

Work was carried out on the propellers, rudders, bow thrusters and other engineering projects, whilst A&P painters applied the new silicone-based paint system on the underwater hull which had been hydro-blasted.

Designed by German engineer Werner Von Braun, the V2 had four key points that marked the V2 out: large liquid fuel rocket engines, supersonic aerodynamics, gyroscopic guidance, and rudders in jet control.

A second version was crafted on the same airframe with the twin booms given greater sideplane area to augment the vertical rudders.

Autopilot systems combine mechanical rudders with navigation systems.

Exhaust vanes and external rudders in tail section shown.

Lippisch changed the system of vertical stabilization for the DFS 194's airframe from the earlier DFS 39's wingtip rudders, to a conventional vertical stabilizer at the rear of the aircraft.

Northrop had investigated several means of applying directional control that would least infringe on the aircraft's radar profile, eventually settling on a combination of split brake-rudders and differential thrust.

Rudders are rotated to generate a lateral force which turns the boat.

Sea turtles fly through the water, using the up-and-down motion of the front flippers to generate thrust; the back feet are not used for propulsion, but may be used as rudders for steering.

The torpedo was fitted with elevators controlled by a depth-keeping mechanism, and the fore and aft rudders operated by the differential between the drums.

The V-2 was guided by four external rudders on the tail fins, and four internal graphite vanes in the jet stream at the exit of the motor.

Ward 2004, p. 28. The square twin fins and rudders proved too weak; they collapsed and the aircraft crashed after it entered an inverted spin during the testing of the terminal dynamic pressure in a dive.
