Problems solved by technology

[0004] The stability of the water surface aircraft between the full-machine dynamic model and the actual aircraft satisfies the similarity in geometric shape, weight center of gravity and inertia, so the water tank test of the full-aircraft dynamic model can compare the real performance of the actual aircraft. Unfavorable factors such as water currents, swells, and crosswinds are disturbe

Embodiment Construction

[0017] Such as figure 1 , 2 , Shown in 3,4, test procedure of the present invention is as follows:

[0018] a. Installation of the whole machine dynamic model and test device:

[0019] Install the full-machine dynamic model 1 on the airworthiness instrument 3 under the hydrodynamic high-speed test trailer 2, and the active connection point between the airworthiness instrument 3 and the full-machine dynamic model 1 is the center of gravity point of the full-machine dynamic model, and the whole machine The dynamic model 1 can freely pitch and rotate around the center of gravity. The navigation piece 4 at the front end of the whole machine dynamic model 1 cooperates with the navigation bar 5 at the bottom of the hydrodynamic high-speed test trailer system to prevent the model from yawping during the test. The equipment related to the stability performance test of the dynamic model includes a resistance meter 6, a gyroscope 7 and an interference rope 8. The resistance meter 6 is...

Abstract

Disclosed is a surface aircraft stability whole-machine power model basin test method. The surface aircraft stability whole-machine power model basin test 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. Specifically, the method comprises observing and recording the motion state and the motion process of the whole-machine power model (1) under disturbance; during the test, recording the state of the whole-machine power model (1) as well parameters such as the angle of deflection of flaps, the angle of deflection of an elevator, test weight and center of gravity and test speed. After finishing the test, data analyzing personnel should perform comprehensive analysis on the collected data according to the collected data and test phenomena as well as validity evaluation on test data. The surface aircraft stability whole-machine power model 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 stability full-machine dynamic model pool. Background technique [0002] Surface aircraft has advantages that general land aircraft and ships do not have. It can take off and land safely on the water surface, and can fly at high speed in the air. Surface aircraft plays an important role in national defense construction and national economic development. Military missions such as transportation, maritime patrol, early warning, attacking surface ships, and anti-submarine can also be used in civilian fields such as maritime rescue, material transportation, and environmental monitoring. With the current national defense construction and economic development in our country, the demand for high-performance surface aircraft is increasingly urgent , [0003] Stability is the most important performance of a surface aircraft and an important index to measure the performance of a su...
