Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] combine Figure 1 to Figure 4 , the present invention is an intelligent on-board airworthiness instrument, including two large fans 3 arranged at the stern of the ship through brackets, and a force measuring device 2 located between the fans and the hull 1 of the self-propelled model. The two fans should be arranged along the width of the ship, and the diameter of the fan 3 is about 0.08-0.3B (B is the width of the self-propelled model ship), and they are on the same horizontal plane. The two wind turbines are installed in parallel at the tail of the self-propelled model hull, 0.2-0.5L away from the stern (L is the designed captain of the self-propelled model hull). The force measuring device is installed between the fan and the ship model, 0.2-0.4D away from the deck of the ship model (D is the hull depth of the self-propelle...

Abstract

The invention provides an onboard airworthiness instrument, comprising a support, a force measuring device and two fans. The support is of an integrated structure, and includes two horizontal beams which are vertically arranged and a vertical beam arranged between the two horizontal beams, two ends of the lower horizontal beam are downwardly vertically provided with lower connecting columns, two ends of the upper horizontal beam are upwardly vertically provided with upper connecting columns, the two fans are arranged on the two upper connecting columns respectively, the two lower connecting columns are connected with the tail of a self-propelled model hull, and the force measuring device is arranged on the vertical beam. The intelligent onboard airworthiness instrument can provide auxiliary power for a ship model, and perform a related hydrodynamic performance test. Since a large-scale self-propelled model is difficult to arrange anchoring equipment under a real sea state, the intelligent onboard airworthiness instrument is high in boosting efficiency, simple and convenient to install, reasonable in structure, low in cost and excellent in test performance, the intelligent onboard airworthiness instrument is of great significance to this kind of tests, and has wide application prospects.

Description

technical field [0001] The invention relates to an intelligent on-board airworthiness instrument, which is a new hydrodynamic performance testing device for a large-scale self-propelled model of a ship in actual waters. Background technique [0002] Nowadays, countries are paying more and more attention to the environmental adaptability of ships in complex and harsh sea areas. In addition, there are serious inherent defects in small-scale ship model tank tests and real ship tests, which make it difficult to meet the measurement accuracy and various requirements of the test. Promote scholars to carry out research on the hydrodynamic performance of large-scale ship models under real sea conditions. [0003] The main research contents of large-scale ships include: carrying out research on the resistance performance of excellent ship types, seakeeping performance of ships under real sea conditions, developing high-efficiency propellers, and developing additional hydrodynamic and...
