Abstract

The present invention provides a net-casting large-scale ship model brake device. The device comprises a deceleration net, a cable, a hoist and an emitter. The net-casting large-scale ship model brakedevice is inspired by a brake umbrella employed when an airplane is landing, and is a simple and practical hydrodynamic guidance device. The emitter is arranged at the middle portion and installed ona ship model tail deck, the deceleration net is casted into water at a certain angle, and netting is filled with sea water to generate resistance to allow the ship model to be decelerated and braked;and the hoist returns the deceleration net after the ship model stops motion, and the emitter is reinstalled into the ship model for usage for the next time. The net-casting large-scale ship model brake device is simple in structure, convenient to operate and high in performance cost ratio, and effectively solves the brake problem of a large-scale ship model self-propulsion test under an actual sea condition.

Description

technical field [0001] The invention belongs to the field of test equipment, and in particular relates to a net-throwing type large-scale ship model braking device. Background technique [0002] The adaptability of the ship environment is an important index to measure whether the performance of the ship and its equipment can be fully utilized and improve its overall performance in the information age. Ships are constantly developing in the direction of high performance, high speed, and safety and reliability. Therefore, ships are required to have good navigation safety performance under high sea conditions or strong winds and waves, and higher and higher requirements are put forward for the performance of ship platforms. Scholars from all over the world pay special attention to the research on the seaworthiness of ships in complex and harsh marine environments, which is of great significance to the safety of ships in actual marine environments, comprehensive navigation perfo...
