Displacement Hull-DTMB5415:
DTMB 5415 was conceived as a preliminary design for a surface combatant by the US David Taylor Model Basin (DTMB) in the early 1980s. This model has been used as one of the benchmark models for the ship displacement hull. The hull geometry includes both a sonar dome and transom stern.
Discriminators:
- Automated meshing of the geometry
- Superior speed enables transient simulations which are inherently more accurate
- Can include complex features and tight clearances
- Ease-of-use
Design Issues/Benefits:
- Predict performance to within 5 %
- Predict loads
- Reduce noise
