Hydrodynamic performance testing method of water surface aircraft

Abstract

A hydrodynamic performance testing method of a water surface aircraft is characterized in that the following testing steps are included as follows (a), test equipment is installed; (b), the testing method is as follows: two forces FX and FZ are respectively applied on a water surface aircraft test sample (2), the outputs of a two component force balance (6) and a single component force balance (13) are measured to make sure FX1 on the two component force balance (6) is the FX, the sum of FZ1 on the two component force balance (6) and FZ2 on the single component force balance (13) is FZ. A hydrodynamic test trailer with high speed is started and is also used for collecting data. According to collected test results, the data need to be analyzed, and the hydrodynamic performance of the water surface aircraft in the process of sliding on the water surface is acquired. The hydrodynamic performance testing method of the water surface aircraft has the advantages that test influence between force and torque caused by the characteristics of a balance is avoided by using the two component force balance and the single component force balance, and the hydrodynamic test precision of the water surface aircraft is improved in the process of taking off on the water surface.

Description

technical field [0001] The present invention relates to the hydrodynamic performance test field of seaplane, amphibious aircraft, ground effect aircraft (wing-in-ground effect ship) and other new-concept water surface aircraft when taxiing and taking off on the water surface, and specifically relates to a hydrodynamic performance test method of water surface aircraft . Background technique [0002] The hydrodynamic performance test of the surface vehicle includes two model tests using a single fuselage and a full-fledged aircraft with wings. The test method of the single fuselage has always been a model that is completely free, and different lifts are performed by applying a vertical force at the center of gravity. This method can simulate the water resistance of the aircraft in the process of gliding on the water surface, and can obtain the vertical motion of the fuselage of the aircraft gliding on the water surface under a specific lift. Utilize the mode of the whole mach...
