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
A fault model, falls under one of the following assumptions: single fault assumption: only one fault occur in a circuit. if we define k possible fault types in our fault model the circuit has n signal lines, by single fault assumption, the total number of single faults is k×n. multiple fault assumption: multiple faults may occur in a circuit.
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.
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.
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.
This caused the aircraft to break up in mid air and crash into the water, killing all 102 people on board. [28] 7 March 2007 – Garuda Indonesia Flight 200: poor crew resource management and the failure to extend the flaps led the aircraft to land at an "unimaginable" speed and run off the end of the runway after landing. Of the 140 occupants ...
FADEC also monitors a variety of data coming from the engine subsystems and related aircraft systems, providing for fault tolerant engine control. Engine control problems simultaneously causing loss of thrust on up to three engines have been cited as causal in the crash of an Airbus A400M aircraft at Seville Spain on 9 May 2015 .
Having developed a suitable design for such an aircraft, development activity on the Lampyridae programme proceeded to the construction of a single three-quarter scale piloted model of the aircraft. [4] This model was initially used for a series of wind tunnel tests. Commenced during 1985, these tests are known to have involved at least two ...
