Embodiment Construction

[0016] Such as figure 1 , 2 Shown, test procedure of the present invention is as follows:

[0017] a. Installation of the whole machine dynamic model and test device:

[0018] The whole machine dynamic model 1 is installed under the hydrodynamic high-speed test trailer 15. The test device includes the center of gravity connecting rod 2, small block 3, heave rod 4, navigation rod 6 and airworthiness instrument 7. The lower end of the center of gravity connecting rod 2 is connected with the whole machine. The center of gravity of the power model 1 is hinged, and the upper end is fixedly connected to the heave bar 4. The heave bar 4 passes through the small block 3 and can move freely in the vertical direction. The small block 3 is placed on the airworthiness instrument 7 and can move along the Free movement in the longitudinal direction within a certain range, the navigation rod 6 is fixed on the airworthiness instrument 7, and the navigation rod 6 passes through the navigatio...

Abstract

Disclosed is a surface aircraft seakeeping whole-machine power model water basin test method. The method comprises the test steps of a, installation of a whole-machine power model and a test device; b, installation of a data collecting device; c, basin test of the whole-machine power model. After finishing the test steps, data analyzing personnel can firstly analyze the validity of collected data, deletes invalid data and records content including the angle of deflection of flaps, the angle of deflection of an elevator, the weight and the center of gravity of the test model, the speed of a trailer during the test, the mean value of a resistograph and the amplitude of a gyroscope (13), a displacement meter (11) and an acceleration sensor (14). The surface aircraft seakeeping whole-machine power model water basin test method has the advantages of being practical, feasible, simple in operation and reliable in test results.

Description

technical field [0001] The invention specifically relates to a test method for a water surface aircraft seakeeping full-machine dynamic model pool. Background technique [0002] Surface aircraft can not only safely take off and land on the water surface, but also fly at high speed in the air, which plays an important role in national defense construction and national economic development. Surface aircraft can be used not only for military missions such as military material transportation, maritime patrol, early warning, attacking surface ships, and anti-submarine, but also for civilian fields such as maritime search and rescue, environmental monitoring, and forest fire fighting. With the national defense construction and economic development in our country, the demand for high-performance surface aircraft is increasingly urgent. [0003] Seakeeping is one of the most important hydrodynamic properties of a surface vehicle, and an important indicator to measure the performanc...
