Description

Technical Field

[0001] The present invention relates to the technical field of ship airflow field design and evaluation, and in particular to a dual-space airflow field collaborative testing system and method. Background Art

[0002] Outdoor airflow field testing technology is mainly used in the evaluation of aerodynamic impacts during aircraft take-off and landing. In the field of ship design, the correlation between outdoor airflow field testing and overall design technology is gradually increasing.

[0003] The so-called dual space refers to the accessible measurement space on the ship deck (near field space) and the inaccessible measurement space outside the ship (far field space). The existing airflow field test method can only use an independent test system to measure one space separately. When measuring the same ship platform, its synchronization, real-time and correlation are difficult to reflect.

[0004] In recent years, with the development of outdoor airflow field testing technology, different space testing methods and processes have shown digital and automated characteristics, but there are still the following limitations:

[0005] 1) Cross-space test data lacks a connected measurement channel. The characteristics of a ship's airflow field are mainly affected by two spaces: one is the near-field space on the deck, where the incoming air flow begins to form laminar flow, vortex flow and other airflow characteristics under the influence of the overall layout configuration; the other is the far-field space outside the deck, where the flow field that forms the airflow characteristics develops, mixes, and dissipates to the far field to form the far-field airflow field morphology. Due to the limitations of the testing methods of the existing technology, the test data of the two spaces are independent of each other, resulting in the inability to establish a correlation channel for the airflow field that changes from the near-field space to the far-field space.

[0006] 2) The synergy of test systems in different spatial areas lacks a common control platform. The test range of the airflow field in the field of ships and other places is usually large (the area length is hundreds of meters and the height is more than one hundred meters), the distance between the test systems is large, and the operation interval is large. The test systems in the prior art are independent of each other, and there is no common control platform or communication channel, resulting in separate test operations. Summary of the invention

[0007] The technical problem to be solved by the present invention is to provide a dual-space airflow field collaborative testing system and method, which can realize the collaborative control of cross-space airflow field interconnection testing and cross-space area testing systems, and can effectively improve the synchronization, real-time and correlation of airflow field measurements in the near-field space and far-field space of ships.
