Specific embodiment
The embodiment of the present invention is described below in detail, the embodiment is exemplary, it is intended to it is used to explain the present invention, and
It is not considered as limiting the invention.
The purpose of the present invention is realizing safety examination of the full-scale solid engines under the effect of big extruding force, mention thus
Go out a kind of safety testing device for examining full-scale solid engines under the effect of big extruding force, when simulating aircraft landing,
Because fortuitous event undercarriage could not be opened, airborne missile bears the process of aircraft landing weight with solid engines.
Present invention oil cylinder, control system and thrust pickup constitute extruding force bringing device, provide for test required
Nearly hundred tons of extruding forces cooperate lower resistance stripper plate, compose the extruding force of actually applied extruding force spectrum and setting on the engine
It is as consistent as possible, meet extruding force precision and the requirement of extruding force-time spectrum.Double-layer elastic air cushion is designed in engine bottom,
Interference of the deformation of engine vertical direction to test when reducing horizontal addload extruding force, it is vertical when making it with aircraft landing to add
The state for carrying extruding force is consistent.
As shown in Figure 1, safety examination of the full-scale solid engines of examination in the present embodiment under the effect of big extruding force
Experiment device, including carrying wall 1, elastic air cushion, stripper plate, pressure sensor 5 and horizontal addload system.
Tested 2 side of full-scale solid engines is against carrying wall 1 and is placed on elastic air cushion；Stripper plate is placed on
The other side of tested full-scale solid engines 2, and connect by pressure sensor 5 with horizontal addload system；The level
Loading system applies the extruding force of horizontal addload by stripper plate to tested full-scale solid engines 2.
The horizontal addload system includes oil cylinder 6, control system 9 and oil piping system 8, and control system 9 is squeezed according to setting
Pressure-time profile requirement, controls oil piping system 8 and oil cylinder 6 generates required extruding force, and is loaded by pressure sensor 5
On lower resistance stripper plate 4.
The stripper plate uses lower resistance stripper plate 4, and the lower resistance stripper plate 4 is cooperated with ground using smooth idler wheel.
The elastic air cushion uses Double-layer elastic air cushion 3, when corresponding deformation occurs for tested full-scale solid engines 2
Afterwards, upper layer elastic air cushion ruptures gas leakage, continues the tested full-scale solid engines 2 of support by lower layer's elastic air cushion.
