There are variations where gudgeons are mounted to the rudder and boat, and a pivot clevis pin is inserted into these gudgeons, or the pintles are fastened to the boat, and gudgeons are attached to the rudder. In any case, the fitting with the hole is referred to as a gudgeon. They are used to attach the rudder to the boat so that it can swing ...
An article on fin and rudder design; "Tail Unit Design" - with a paragraph on the effects of fin and rudder stall, in a 1941 Flight article here: - page 1 of article here: The relevance to the Halifax is in the reference to angles of yaw with partial engine failure; "Stalling of the fin may occur at about 15 deg. angle of yaw. This is a large ...
Typical trim tabs on aileron, rudder and elevator. Trim tabs are small surfaces connected to the trailing edge of a larger control surface on a boat or aircraft, used to control the trim of the controls, i.e. to counteract hydro- or aerodynamic forces and stabilise the boat or aircraft in a particular desired attitude without the need for the operator to constantly apply a control force.
NTSB chair Jennifer Homendy accused the FAA of "downplaying the urgency" of potentially defective rudder systems on some Boeing 737 jets.
Gust lock on a rudder. A gust lock on an aircraft is a mechanism that locks control surfaces and keeps open aircraft doors in place while the aircraft is parked on the ground and non-operational. Gust locks prevent wind from causing unexpected movements of the control surfaces and their linked controls inside the aircraft, as well as aircraft ...
The vertical tail sometimes features a fillet or dorsal fin at its forward base, which helps to increase the stall angle of the vertical surface (resulting in vortex lift), and in this way prevent a phenomenon called rudder lock or rudder reversal. Rudder lock occurs when the force on a deflected rudder (e.g. in a steady sideslip) suddenly ...
The National Transportation Safety Board is investigating an United Airlines 737 MAX 8 flight last month that experienced "stuck" rudder pedals.
This story was updated to include new information. The National Transportation Safety Board has issued an urgent warning to airlines that fly the Boeing 737, saying a failure first seen on a ...
