Definitions
- the invention relates to an axial flow machine with an asymmetrical air inlet and a compressor directly downstream of the air inlet with a guide vanes formed from inlet guide.
- Such axial flow machine with asymmetric air intake occur, for example, in the core engines of turboprop or helicopter engines.
- flow problems of the first compressor stage can result, which can lead to a partial detachment of the flow at this blade stage with consequent pumping and loss of efficiency.
- the invention is therefore based on the object to avoid the disadvantages of the known solutions of the prior art and to provide an improved solution for symmetrical as possible flow of the first compressor stage in an axial flow machine with asymmetric air inlet.
- the peripheral disturbances caused by the asymmetrical air inlet are minimized and thus the first compressor stage largely passes on circumferentially symmetrical inlet conditions, which leads to improved stability and improved efficiency of the compressor.
- An advantageous embodiment of the invention provides that one or more of the guide gratings following the inlet guide grille have at least individual guide vanes with a blade profile deviating from the remaining guide vanes and / or a different angle of attack.
- An advantageous embodiment of the invention provides that individual vane groups have a blade profile deviating from the remaining vanes and / or angle of attack. This allows a rational production and corresponding cost savings.
- the guide vanes may be arranged in several groups of different geometry.
- a further advantageous embodiment of the invention provides that the guide vanes of the respective vanes groups have mutually differing blade profiles and / or angle of attack.
- a further advantageous embodiment of the invention provides that all guide vanes are profiled differently and / or have a different angle of attack. This means that a targeted profiling of each individual blade or a re-scaling of the individual blades can be carried out, thereby adapting to the asymmetrical flow
- a further advantageous embodiment of the invention provides that the guide vanes are designed to be adjustable. By a different adjustment of at least individual blades or blade groups also the desired effect can be achieved, since this can be done quasi a targeted rescaling of individual blades. This has the further advantage that with changed flow conditions, the individual alignment of the guide grid can be traced.
- Guide vanes are formed on the inlet side of a fixed part and the outlet side of a pivotable part.
- a further advantageous embodiment of the invention provides that an individual control is provided for each or all vanes. This enables individual descendants of each individual blade under changed flow conditions.
- Fig. 2 is a schematic representation of alitissleitgitters of the prior art
- Figure 1 shows a schematic representation of a developed constructivesleitgitters according to the present invention with multiprofiles, i. individual profiling of each individual blade of the inlet guide grille.
- the blades are adapted to the variable circumferentially asymmetrical angle of attack of the inlet guide grille.
- This unbalanced flow is caused by the asymmetric air inlet.
- a constant outflow angle is generated over the entire circumference and the first compressor stage largely passes on circumferentially symmetrical entry conditions. This leads to improved stability and improved efficiency of the compressor.
- Figure 2 shows a schematic representation of a prior art unwound inlet guide grate with circumferentially asymmetrical flow caused by an asymmetric air inlet.
- the leftmost and outermost right vane in the plane of the drawing have separations which continue in the subsequent compressor stages and lead to unstable compressor behavior, i. lead to pumps.
- the outflow angle in this case is not constant over the circumference, but changes at each vane, which likewise can lead to unstable compressor behavior and efficiency losses.
