AXIAL-FLOW COMPRESSOR BLADE

摘要

turbine engineering; axial-flow compressor blades made from laminated composite material; aviation, oil and gas industries. SUBSTANCE: axial-flow compressor blade made from laminated composite material consisting of alternating layers or stacks of layers oriented at angle relative to longitudinal axis of blade differs in that composite material has non-balanced structure relative to selected axes of anisotropy possessing ability of adapting for loading with gas and centrifugal forces, thus ensuring automatic control and alignment of modes of operation of compressor stages. EFFECT: wide field of flexible spin-up of fin making it possible to automatically control mode of operation of compressor stages and ensure gas-dynamic stability at misalignment of stage operation, as well as to control stress and deformation state of material of fin and edges of blades at joint action of gas and centrifugal loads. 7 cl, 4 ex
