Aerospace Blockset Maritime Applications Library

Model and simulate maritime vehicles and ocean environments for marine applications and multi-domain system-of-systems scenarios.

The Aerospace Blockset Maritime Applications Library provides Simulink blocks for modeling maritime vehicles and ocean environments. It supports two key use cases: marine engineers building low-fidelity simulations for early-stage design and operations analysis, and aerospace/defense engineers extending their system models into maritime domains for integrated multi-domain scenarios.

Use this library to:

• Model ocean environments with industry-standard wave spectra, currents, and seawater properties
• Simulate hydrostatic response of surface and subsurface vehicles
• Build low-fidelity marine digital twins for vessel design trade studies and operational analysis
• Integrate maritime models into multi-domain simulations spanning air, land, and sea platforms

Ocean Environment Blocks:

• Irregular Ocean Wave Spectrum - generate realistic sea states using standard spectral models (Pierson-Moskowitz, JONSWAP, Bretschneider)
• Pressure and Density - TEOS-10 compliant equations of seawater
• Temperature and Salinity - depth-dependent ocean properties for subsurface operations
• Synthetic Seafloor Generator - procedural terrain models for bathymetric environments
• Subsea Altitude - above-ground-level computation relative to terrain

Marine Vehicle Dynamics:

• 6-DOF Hydrostatic Response - buoyancy and restoring forces for standard hull shapes (cuboid, cylinder, sphere)

Applications:

• Hydrostatic simulation of surface and subsurface vehicles in ocean environments
• Subsurface vehicle operations with trajectory planning APIs
• Hydrostatic trade studies and vessel stability analysis for surface and subsurface hull forms
• Autonomous surface and underwater vehicle simulation in realistic ocean conditions
• Multi-domain mission scenarios combining maritime, aerial, and ground platforms
• Vessel operational analysis including response to sea state and environmental loads
