Definitions
- the present invention relates to a stage rectifier of a compressor comprising a succession rectifier or stator stages separated by stages rotor blades, each rectifier stage consisting of fixed vanes connecting an inner ferrule to an outer shell.
- Coaxial compressors are well known in itself, and are used in several types of application. In particular, they are used in double motors body, turbofans or turbojets. We also note their presence in power plants. These compressors low or high pressure basically consist of several stages of rotating blades or rotor stages separated by stator stages or rectifiers which have to reposition (straighten) the speed vector of the fluid leaving the previous stage before sending it to the next compartment.
- Each of these rectifier stages is essentially consisting of fixed vanes connecting a ferrule exterior to an interior ferrule, both concentric.
- the blades are joined to the ferrules, both interior and exterior, by rivets, bolts or welds.
- the use of these means of joining presents the major drawback of disrupt the flow and generate a pressure drop in the aerodynamic vein.
- the present invention aims to provide a solution which simplifies the assembly of the blades fixed to both the inner ferrule and the ferrule exterior.
- the present invention aims to allow a solution that offers great simplicity of assembly and which does not require assembly operations additional.
- the present invention also aims to propose a solution that allows the vein aerodynamics of the flow is not affected by the presence welds or rivets at the ferrule.
- the present invention also aims to allow a low cost solution.
- the present invention relates to a stage rectifier of a compressor comprising two ferrules, one inner ferrule and outer ferrule, both concentric and preferably circular and connected one to the other by a series of fixed vanes.
- At least one of ferrules, and preferably the two inner ferrules and exterior, are provided with lights which allow the passage of said blades in these lights in order to allow their attachment to the ferrules.
- blades also have at least one and preferably at their two ends, an opening intended to allow the passage of a locking element. This element of locking will advantageously allow the joining of the blades to at least one and preferably to the two ferrules on the non-functional side, i.e. side of the inner face for the inner ferrule and side of the outer face for the outer shell.
- the joining of the blades to the ferrule or to the ferrules is carried out by passing a strip in one or several pieces, which successively crosses all always blades of the same rectifier stage, and this from non-functional side of the ferrules.
- this strip presents a elastic function and will be embedded in an elastomeric element which protects the different parts, and especially the locking elements.
- Figure 1 shows a general view of the compression stage of a turbofan.
- Figure 2 shows the solution implemented work by the present invention to secure blades fixed to both exterior and interior ferrules.
- a portion 16 and 17 of said fixed blades 60,61,62,63, ... exceeds ferrules 4 and 5.
- the different portions 16 or 17 each also have an opening 20,21,22,23, ... and 30,31,32, ... which allows the introduction of an element of locking (40 and 50 respectively).
- Said element of locking here takes the form of a strip which, in crossing simultaneously either every day 20,21,22, ..., either every day 30,31,32, ... fixed blades 60,61,62,63, ..., secures said fixed vanes to inner 4 and outer 5 ferrules. This occurs on the non-functional side of said shell, that is to say on the inner face of the inner shroud 4 and on the outer face of the outer shell 5.
- this strip presents a elastic function and consists of a single piece.
- the strip can understand several pieces.
- the fixed blades are secured to the two ferrules in this way, on the one hand to the inner ferrule 4 and on the other hand to the outer shroud 5, by through two locking elements 40 and 50. Another possibility is that the fixed blades are not secured together with only one of the two ferrules.
- Such a securing device has several advantages. First of all, it does not entail any defect in the aerodynamic flow stream, which reduces strongly the pressure drops in it.
- Another advantage is that it allows to assemble and secure two types of parts without mechanical link, fixed vanes and ferrule, without modification of the functional aspect of these two types of rooms.
