The importance of fail-safe design for composite structure is clear, particularly the associated problems, and widespread defects due to processing failures make it an imperative even when high-tech quality control processes are employed.

What is an importance of fail-safe system?
Benefits of fail-safe designs include being able to manage the unexpected and mitigating damage if failure occurs. There is no method to help determine which if either of these philosophies should be employed. Engineers must use their judgment on a case-by-case basis.
What is fail-safe design and why does it matter?
In engineering, a fail-safe is a design feature or practice that in the event of a specific type of failure, inherently responds in a way that will cause minimal or no harm to other equipment, to the environment or to people.Some systems can never be made fail-safe, as continuous availability is needed.
What is the concept of fail-safe?
A fail safe system is one which, due to the characteristics of its equipment and components and the way in which they are integrated, is guaranteed that, in the event of any fault appearing, the system will always go to a safe status, normally affecting availability but never, and in no case, affecting safety.
What is a fail-safe and an example?
Collins Dictionary has the following description of the term, as well as an example: Something that is fail-safe is designed or made in such a way that nothing dangerous can happen if a part of it goes wrong. For example: There was a fail-safe mechanism in place to override the controls in case of a malfunction.
What is fail-safe and fail set?
What is meant by ‘fail safe’ and ‘fail set’ in a pneumatic control systems ? On failure of control air supply, the pneumatic actuator may be arranged to move to a position that allows the plant to continue to operate safely, in other words, fully opened or fully closed. This is known as fail safe.
What is another word for fail-safe?

Why are safe life and fail-safe design concepts important in aircraft structure?
In certain areas such as in wing or tail components, structural failure in flight would be catastrophic. The safe-life design technique is employed in critical systems which are either very difficult to repair or whose failure may cause severe damage to life and property.
How can fail-safe methods be used to reduce service failures?
A potential failure arises if the customer forgets the appointment. To preclude this, a fail-safe procedure is to call the customer the day before the intended service.By maintaining a customer database, the dealer can preprint forms with this background information, decreasing errors and the work load.
Is it failsafe or fail-safe?
Something that is fail-safe is designed or made in such a way that nothing dangerous can happen if a part of it goes wrong. The camera has a built-in failsafe device which prevents it from working if the right signals aren’t received.
Is normally open fail-safe?
Normally-Closed Valves, Normally-Open Valves, and Valves that can be Converted between Normally-Open and Normally-Closed. Actuated or automatic valves that revert to a pre-determined position after the actuating force is removed are referred to as “fail-safe” valves.
Is fail safe one word?
verb (used with object), fail-safed, fail-saf·ing. to make fail-safe.
What does it mean to fail open?
Fail Open (FO) means that when there is a loss of signal, the valve opens. If you are using your valve in a back pressure application, such as holding pressure on a separator, a fail open valve would allow you to prevent excessive pressure build up on the upstream side of the valve in the event of a failure.
What do you call a backup person?
fill-in, reliever, stand-in, backup, substitute, relief. compeer, equal, peer, match – a person who is of equal standing with another in a group. locum, locum tenens – someone (physician or clergyman) who substitutes temporarily for another member of the same profession.
What does the fail-safe redundancy mean?
In engineering, redundancy is the duplication of critical components or functions of a system with the intention of increasing reliability of the system, usually in the form of a backup or fail-safe, or to improve actual system performance, such as in the case of GNSS receivers, or multi-threaded computer processing.
What is fail fast and fail-safe iterator?
The Java Collection supports two types of iterators; Fail Fast and Fail Safe. These iterators are very useful in exception handling. The Fail fast iterator aborts the operation as soon it exposes failures and stops the entire operation. Comparatively, Fail Safe iterator doesn’t abort the operation in case of a failure.
Is normally open fail open?
Therefore a normally open valve is one that is open until the actuator is energized to close it; if power to the actuator fails, the valve opens or “fails open”. Likewise with a normally closed valve if power to the actuator fails, the valve closes or “fails closed”.
What is meant by fail-safe condition in PLC?
A system’s being “fail-safe” means not that failure is impossible or improbable, but rather that the system’s design prevents or mitigates unsafe consequences of the system’s failure.
Is fail open Same as normally open?
The term Normally Open (NO) applies to manual valves or dampers which the operator must leave open in normal operation. A control valve that should go to an open position on a control signal failure should be labeled FO, i.e. Fail Open. The control signal may be pneumatic, hydraulic or electric.
