Metal fatigue and aircraft design flaw 6 Structural failure of the right horizontal stabiliser due to metal fatigue and aircraft design flaw 1978-06-26 Helikopter Service Flight 165: North Sea, Norway Sikorsky S-61: Fatigue 18 Rotor blade loosened after fatigue to the knuckle joint: crashed into the sea [10] 1979-05-25 American Airlines Flight 191
For example, the thrust reverser system could be identified by its ATA code 78-30. Untimely deployment of thrust reverser would be a hazard, which could be assigned an identifier based on ATA code 78-30. FHA results are coordinated with the system design process as aircraft functions are allocated to aircraft systems.
There are two generic types of aircraft structure, safe life and fail safe. The former is one that has low residual strength if a primary load-bearing member should fail, whereas the latter has alternative load paths so that if a primary load-bearing member cracks, residual strength remains because the loads can be assumed by adjacent members.
The example shown in the figure on the right illustrates a model-based FDI technique for an aircraft elevator reactive controller through the use of a truth table and a state chart. The truth table defines how the controller reacts to detected faults, and the state chart defines how the controller switches between the different modes of ...
A fault tree diagram. Fault tree analysis (FTA) is a type of failure analysis in which an undesired state of a system is examined. This analysis method is mainly used in safety engineering and reliability engineering to understand how systems can fail, to identify the best ways to reduce risk and to determine (or get a feeling for) event rates of a safety accident or a particular system level ...
The main purpose of the IFCS project is to create a system for use in civilian and military aircraft that is both adaptive and fault tolerant. This is accomplished through the use of upgrades to the flight control software that incorporate self-learning neural network technology. The goals of the IFCS neural network project are.

Basic fault models in digital circuits include: Static faults, which give incorrect values at any speed and sensitized by performing only one operation: the stuck-at fault model. A signal, or gate output, is stuck at a 0 or 1 value, independent of the inputs to the circuit. the bridging fault model. Two signals are connected together when they ...
