Скачать или смотреть UE5 : Ocean Waves : Buoyancy : Ship Launching

This video shows further progress on the buoyancy system for the Ocean Waves project. It consists of two main parts, demonstrating the simulation of a planning hull (Motorboat) and a displacement hull (Research Ship, starts at 10:04). Sound effects were added in the video editor.

00:00 Motorboat launching
00:48 Motorboat in calm water with FPS less than 60
03:01 Motorboat in calm water with FPS greater than 60 [1]
05:04 Motorboat in light breeze
07:40 Motorboat in moderate gale
10:04 Research Ship overview
11:30 Research Ship launching
15:27 From the stratosphere to Research Ship in moderate gale
17:20 Research Ship in moderate gale [2]

[1] The minimum FPS at which Motorboat simulation remains stable depends on its speed and acceleration (at 00:50 and 03:54, you can compare how it behaves on calm water at zero speed with FPS less than 60 and more than 60, respectively).

In this video, the displacement of Research Ship is 5550 t (whereas the design full load displacement is LighweightTonnage + DeadweightTonnage = 5500 + 2550 = 8050 t). [2] Here Research Ship only carries 50 t of payload, as I forgot to increase the deadweight after she was launched.

Estimated performance of the presented watercraft:
Motorboat:
DisplacementAvg = 1.2 t;
MaxSpeed = 15.0 m/s = 29.16 kn;
PropulsionPower [3] = 120.0 kW;

Research Ship:
DisplacementAvg = 7000.0 t;
MaxSpeed = 8.0 m/s = 15.55 kn;
PropulsionPower = 4900.0 kW;

[3] The propulsion power is calculated as the product of the hull speed (MaxSpeed) and the drag force acting on the hull at that speed.
