Abstract

The invention belongs to the technical field of hydrodynamic tests of water surface aircrafts such as amphibious aircrafts and sea planes, and relates to a water surface aircraft wave-striking load full-aircraft power-free model pool test device. The device can ensure that the roll angle, trim angle and relative position of the model do not change, force and moment in three directions of the center of gravity of the model can be measured, a vertical stress situation at a vertical tail of the model can be measured, a water surface condition of the model in the test process is recorded through image pick-up systems installed in front of and behind the model, thereby providing support for subsequent analysis of a splashing situation of the model, and at the same time, the device is simple toadjust and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of hydrodynamic tests of water surface aircraft such as amphibious aircraft and seaplanes, and relates to a water surface aircraft impact wave load full-machine unpowered model pool test device. Background technique [0002] At present, with the improvement of the range of use of water surface aircraft, the requirements for the wave resistance of water surface aircraft in oceans or lakes are gradually increasing, thus putting forward higher requirements for the structural design and strength check of water surface aircraft, so it is necessary to obtain more accurate results through model tests. The wave collision load of the water surface vehicle is used for the structural design and strength check of the water surface vehicle. At present, the main test is the scaled model test of the water surface aircraft without power model crashing into the wave load pool. Through the water tank test of the aircraft cras...
