Neural Network-Based Prediction
A study developed an artificial neural network (ANN) model to predict the failure rate of De Havilland Dash-8 airplane tires. The model utilized a two-layered feed-forward back-propagation algorithm as a learning rule. The inputs to the neural network were independent variables, and the output was the failure rate of the tires. The model was built and validated using six years of data. The validation process involved comparing the ANN model’s predictions with those of a Weibull regression model. The results indicated that the failure rate predicted by the ANN was closer to the actual data than the failure rate predicted by the Weibull model, suggesting a higher accuracy in predicting tire?failures.
Passenger Comfort and Noise Levels
Another important aspect of aircraft safety is passenger comfort, which can indirectly affect the overall safety experience. The Dash-8Q variant of the aircraft has made significant advancements in this area.
Noise Reduction
The Dash-8Q has achieved a new level of cabin comfort, particularly in terms of noise reduction. The introduction of the Active Noise and Vibration Suppression (AVNS) system, along with additional features, has provided a more comfortable cabin environment for both passengers and crew. Continuous test programs have led to further advancements, significantly reducing noise levels inside the?cabin.
