System Testing

  • Mark IV hardware production testing is conducted through four distinct phases: components, cards, modules, and panels.
  • During the component testing phase, all integrated circuits undergo a rigorous screening process, which includes temperature cycling, hermetic seal inspection for fine and gross leakage, and burn-in. Following this, the ICs are subjected to a comprehensive 100% electrical parameter test.
  • For printed wire boards a burn-in process occurs at 155oF over 160 hours, with electrical power continuously applied. Subsequently, these cards undergo in-circuit testing, followed by a functional test. If specialized calibration is needed, it is conducted separately after the initial testing phase.
  • Both the in-circuit and functional tests are currently performed using a General Radio GR2270 tester. These tests are meticulously programmed, ensuring a high level of consistency and precision throughout the testing process.

Software features

  • Gas turbine control installation is tailored to the specific preferences. This necessitates a highly modular and easily adaptable software structure, particularly in areas frequently subject to modifications, such as start-up and shut-down sequences.
  • Moreover, configuring this distinct software setup while upholding stringent reliability standards presents yet another formidable challenge.
  • Lastly, the fault-tolerant redundant processor design mandates a meticulously crafted communication system capable of functioning seamlessly even in the event of partial failures.

Frequently Asked Questions

How does the customization of each gas turbine control installation impact the software design?
Installation is tailored to the specific needs of the customer, which necessitates a highly modular and easily adaptable software structure. This ensures that the software can be customized to include the desired options and features.

Could you elaborate on the modularity of the software and why it's essential?
Modularity is crucial because it allows for easy modifications, especially in areas that undergo frequent changes, such as start-up and shut-down sequences. This flexibility ensures that the software can be adjusted to meet evolving requirements without compromising its integrity.

How was the challenge of maintaining high reliability in the software addressed?
Maintaining high reliability while customizing the software for individual installations is a complex task. It involves rigorous testing, fault-tolerant design principles, and careful configuration management to ensure that the software remains reliable even with varying customer-specific requirements.

Can you explain the concept of a fault-tolerant communication system and its importance in software design?
A fault-tolerant communication system is designed to continue functioning even in the presence of partial failures. In the context of the Mark IV, this ensures that critical data and commands can be exchanged reliably between redundant processors, enhancing system reliability and safety.
