Abstract
The utility model relates to aircraft wing leading edge pipeline installing area, particularly relates to a kind of bourdon's tube mounting flange, installs the more difficult problem in location to solve bourdon's tube.Bourdon's tube mounting flange is used for bourdon's tube to be fixedly mounted in leading-edge slat, and comprising: flange, be fixedly connected on the axial end portion of bourdon's tube, flange center offers the through hole be communicated with bourdon's tube; Flange stretches out sheet, is fixedly installed on flange, and it is identical with the row in the flute shape hole on bourdon's tube that flange stretches out the quantity of sheet, and the arrangement angle that each flange stretches out between sheet is identical with the arrangement angle of respectively arranging between flute shape hole.When bourdon's tube mounting flange of the present utility model is installed, stretch out sheet by the flange identical with the row in the flute shape hole on bourdon's tube to position, can to avoid in fitting process that bourdon's tube is counter fills problem, effectively ensure that flute shape hole spray angle meets designing requirement, eliminate safe hidden trouble.
Description
Technical field
The utility model relates to aircraft wing leading edge pipeline installing area, particularly relates to a kind of bourdon's tube mounting flange.
Background technology
Aircraft bourdon's tube cross section is generally circle, if use common flange to weld with bourdon's tube, because slat leading edge structure dividing plate is to the stop of sight line, in fitting process, operating personal is easy to fill counter for bourdon's tube, cannot ensure that the flute shape hole spray angle on bourdon's tube meets designing requirement.The most important thing is, this maloperation is difficult to find, once system is opened, the structure in the high-temperature gas opposite joint nose of wing that flute shape hole is ejected and cable cause damage, for follow-up test and flight bring potential safety hazard.
Summary of the invention
The purpose of this utility model is to provide a kind of bourdon's tube mounting flange, installs the more difficult problem in location to solve bourdon's tube.
The technical solution of the utility model is:
A kind of bourdon's tube mounting flange, for being fixedly mounted in leading-edge slat by bourdon's tube, comprising:
Flange, is fixedly connected on the axial end portion of described bourdon's tube, and described flange center offers the through hole be communicated with described bourdon's tube;
Flange stretches out sheet, is fixedly installed on described flange, and it is identical with the row in the flute shape hole on described bourdon's tube that described flange stretches out the quantity of sheet, and the arrangement angle that each described flange stretches out between sheet is identical with the arrangement angle between described each row's flute shape hole.
Alternatively, in the side of stretching out sheet away from described flange of described flange, the sheet groove parallel with the vertical edge of aircraft leading edge dividing plate is offered.
Alternatively, described flange is fixedly connected with described aircraft leading edge dividing plate by bolt.
Alternatively, the profile of described flange is identical with described leading edge of a wing section.
Alternatively, described flange be one piece by stamping forming titanium alloy sheet.
The utility model has the advantage of:
When bourdon's tube mounting flange of the present utility model is installed, stretch out sheet by the flange identical with the row in the flute shape hole on bourdon's tube to position, can to avoid in fitting process that bourdon's tube is counter fills problem, effectively ensure that flute shape hole spray angle meets designing requirement, eliminate safe hidden trouble.
Accompanying drawing explanation

Fig. 2 is the front view after the utility model bourdon's tube mounting flange is installed;
Fig. 3 is the lateral plan after the utility model bourdon's tube mounting flange is installed.
Detailed description of the invention
Be described in detail of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 3, a kind of bourdon's tube mounting flange of the present utility model, for being fixedly mounted on bourdon's tube 5 in leading-edge slat.Bourdon's tube mounting flange can comprise flange 1 and flange stretches out sheet 2.
Flange 1 is fixedly connected on the axial end portion of bourdon's tube 5, and flange 1 center offers the through hole 4 be communicated with bourdon's tube 5.
Flange stretches out sheet 2 and is fixedly installed on flange 1, it is identical with the row (each line arranging the center of circle, flute shape hole 51 is parallel along bourdon's tube 5 axis direction with shown in Fig. 3) in the flute shape hole 51 on bourdon's tube 5 that flange stretches out the quantity of sheet 2, and the arrangement angle that each flange stretches out between sheet 2 is identical with the arrangement angle of respectively arranging between flute shape hole 51.
When bourdon's tube mounting flange of the present utility model is installed, stretch out sheet 2 by the flange identical with the row in the flute shape hole 51 on bourdon's tube 5 to position, can to avoid in fitting process that bourdon's tube is counter fills problem, effectively ensure that flute shape hole spray angle meets designing requirement, eliminate safe hidden trouble.
Further, in the side of stretching out sheet 2 away from flange of flange 1, offer the sheet groove 3 parallel with the vertical edge of aircraft leading edge dividing plate 6 (being again leading edge slat dividing plate), guarantee during installation that sheet groove 3 is parallel with the vertical edge of leading edge dividing plate 6, play positioning action.
Flange 1 can adopt multiple applicable material, and in the present embodiment, flange 1 one pieces is by stamping forming titanium alloy sheet, and its profile is substantially identical with leading edge of a wing section.In addition, stretch out on sheet 2 at flange 1 body and flange and be provided with multiple bolt hole, be fixedly connected with aircraft leading edge dividing plate 6 by bolt; In the present embodiment, the bolt hole on flange 1 body comprises laterally zygomorphic two, and each flange stretches out sheet 2 and arranges a bolt hole.
When the utility model bourdon's tube mounting flange is installed, implement according to the following steps:
Step one: by the through hole 4 of bourdon's tube 5 one end alignment flange dish 1, ensures that flange stretches out sheet 2 consistent with the jet-impingement angle in flute shape hole 51, completes welding of flange 1 and bourdon's tube 5.
Step 2: by bourdon's tube 5 other end through leading edge dividing plate 6, until flange 1 (6 fit with leading edge dividing plate.
Step 3: rotary flange dish 1, after confirming that sheet groove 3 is parallel with the vertical edge of leading edge dividing plate 6, uses screw bolt and nut to be fixed on leading edge dividing plate 6 by flange 1, completes installation.
The above; be only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should described be as the criterion with the protection domain of claim.
