Embodiment Construction

[0023] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods. Spatially relative terms such as "below", "beneath", "under", "lower", "above", "on", "higher", etc. are used to facilitate description to explain the relative The orientation of two elements means that these terms are intended to encompass different orientations of the device in addition to orientations other than those shown in the figures. In addition, for example, "one element is on / under another element" may mean that two elements are in direct contact, or that there are other elements between the two elements. In addition, terms such as "first", "second", etc. are also used to describe various elements, regions, sections, etc. and should not be taken as limitations. Similar terms refer to similar elements throughout the description.

Abstract

The invention provides an offshore airspace engine test bed which is arranged on a gravel layer laid on offshore gravel. The offshore airspace engine test bedincludes a concrete embankment and a semi-submersible platform which are arranged on a gravel layer, one side of the semi-submersible platform is close to the concrete embankment, and the other opposite side of the semi-submersible platform faces seawater. The semi-submersible platform comprises a lower part which is submerged into seawater and an upper part which is exposed out of the seawater. A platform deck at the upper part of the semi-submersible platform is at least provided with a propellant storage tank, an engine mounting bracket and at least one track for transferring an engine. The track is laid in the middle of a platform deck from the coast to seawater, and the propellant storage tank is arranged near the track and used for providing propellants for the engine arranged on the track. After the engine installed on the engine mounting bracket moves to the test run position along the track, a spray pipe of the engine faces the seawater, a diversion trench structure does not need to be built, and it is guaranteed that high-temperature fuel gas generated in the test run process can be directly sprayed to the seawater.

Description

technical field [0001] The invention relates to the technical field of aerospace engine test runs, in particular to an off-shore aerospace engine test bench. Background technique [0002] In recent years, the tonnage level of liquid aerospace engines has gradually increased, and the demand for engine testing has surged. Due to the noise problem generated during the test run of the high-thrust engine, it is very difficult to select a site for the construction of an engine test stand on land. [0003] In order to effectively utilize the advantages of geographical resources of offshore islands and reefs and reduce the investment cost of test bench construction, it is urgent to propose an aerospace engine test bench built near the coast. Contents of the invention [0004] Those skilled in the art will recognize additional features and advantages after reading the detailed description and after viewing the accompanying drawings. [0005] The invention provides a near-coast ae...
