Definitions
- the invention relates to a method for detecting a shaft break in a Flow engine with the goal, then a suitable speed limit Measure, in particular a quick fuel cut-off an aircraft gas turbine system to initiate, wherein a torque-emitting Turbine rotor and a torque-absorbing aggregate on the regarding of a break to be monitored, essentially at the end in at least two Rolling bearings are connected to each other.
- a commercial disadvantage for a problem to be solved in this way is therefore the large number of systems used, depending on the specific conditions of the the respective aircraft engine must be adapted in terms of design.
- at Aircraft engines that break waves between fans according to the Tangling principle and safely intercept low pressure turbine is always with the total loss of Blading with correspondingly high replacement costs.
- On mechanical system with a reference shaft is at least if required subject to the partial loss of components, in addition to the fact that a such system means additional mass for the engine, which is what one Aircraft engine is of course undesirable.
- the mass-cost ratio of mechanical solutions for realizing the required function of a safety shutdown in the event of a shaft break between Fan and low pressure turbine is from the point of view of manufacturing costs and operating costs classified as disadvantageous. Electro-mechanical or electronic solutions are over from the point of view of the total costs here clearly has an advantage.
- the invention is based, an inexpensive task and safe method for detecting a wave break in a Fluid power machine and an associated device to accomplish.
- the object is characterized by the features of Main claim solved.
- the present invention preferably relates to the problem of a wave break between the fan as a torque absorbing unit and the torque-releasing low-pressure turbine rotor of an aircraft engine or a flight gas turbine system and the required speed limitation of the Low pressure turbine rotor, however, is analogous to any one Fluid power machine can be used.
- the aim is to have such a procedure and associated device to use that on an electromechanical / electronic Execution based.
- the rotational frequency of the respective shaft end in the respective rolling bearing can be determined. distinguish the rotational frequencies of the two shaft ends differ significantly from one another obviously a wave break before, so that a suitable one speed-limiting measure is initiated.
- Prefers can use a filter unit to adjust the rotation frequency for both rolling bearings in real time of the roller bearing cage and / or the rollover frequency of the roller bearing outer ring and / or the rollover frequency of the roller bearing inner ring and / or the Rolling body rotation frequency determined and from this the rotational frequencies in the Rolling bearings mounted shaft ends can be determined separately.
- Figure 4 shows the determination of the nominal pressure angle ⁇ O and the operating pressure angle ⁇ B for angular contact ball bearings.
- f n denotes the rotational frequency of the respective shaft end in the rolling bearing and z the number of rolling elements.
- vibration spectrum can also be generated by suggestions outside of the rolling bearing.
- a typical one Vibration spectrum for a rolling bearing with an accelerometer as FIG. 5 shows the measurement signal pickup.
- the aircraft engine shown in Figure 6 consists of a high pressure system 1 and a low pressure system 2 with shafts 3 and 4 for power transmission are equipped.
- the two shafts 3, 4 are not mechanically connected to one another connected and thus rotate independently of each other.
- the low pressure system 2 consists of the fan 2a, the rotor of the booster stage 2b and the low-pressure turbine rotor 2c, which are connected to one another via the shaft 3.
- the high-pressure compressor rotor 1a and the high-pressure turbine rotor 1 b connected together.
- the shaft 3 is on the torque-absorbing side Aggregates in the form of the fan 2a and the booster stage 2b via an as Grooved ball bearing trained roller bearing 6 is mounted.
- the shaft 3 is over a Rolling bearing 7 is supported with cylindrical rolling elements.
- a separate measuring channel is identical in each case for the two roller bearings 6 and 7 Execution provided. Since only one measurement signal per roller bearing 6 or 7 is required, the two measuring signal recorders 8a and 8b are connected to an OR gate 10 activated. In an analogous manner, the measurement signal pickups 9a and 9b an OR gate 11 responsible.
- OR gates 10 and 11 each leave a complex-period measurement signal in the time domain, which can be assigned to the respective roller bearings 6 and 7.
- t denotes a point in time
- T the period of the periodic function.
- the basic equations for a Fourier-transformed complex-period measurement signal are known to the person skilled in the art and are therefore not given here. It should only be mentioned that the Fourier transformation is carried out by the FFT processors 12 and 13.
- the Fourier-transformed measurement function is now available in the form of the frequency representation. If, on the other hand, the calculation were carried out as a discrete Fourier transformation, the computational effort would no longer be in the real-time capable range. Therefore, recursion formulas are used that reduce the computing effort by a factor of 10 3 . Mature processes for this Fast Fourier transmission are available in different versions. The FFT processors 12 and 13 handle this task in real time.
- the measured value functions which have been subjected to a significant data reduction without loss of information, then pass through the filters 14 and 15.
- These filters 14, 15 are designed such that they can only pass a frequency band from 0 Hz to the maximum frequency which can be followed Equation (C) given above (in connection with FIGS. 2-4), which represents the rollover frequency of the rolling bearing inner ring, is determined.
- the value f n in this equation (C) corresponds to the maximum permissible rotational frequency of the low-pressure turbine rotor 2c.
- the filtering mentioned takes place almost instantaneously under real-time conditions.
- the arithmetic processors 16 and 17 can carry out a comparison of the rotational frequencies for the rolling bearings determined according to equations (A) to (D), a predefined spreading range not being allowed to be exceeded.
- the Gaussian method of least squares is preferably used to determine the effective values f n1 and f n2 and the standard deviations ⁇ 1 and ⁇ 2 of the measurement results, which are then used as the basis for a subsequent evaluation.
- the rotational frequency information is thus in the form ⁇ f n1 ⁇ ⁇ 1 ⁇ and ⁇ f n2 ⁇ ⁇ 2 ⁇ for both roller bearings 6, 7.
- the inflow to the fuel ring line 19 is equipped with a fuel quick-closing valve 20.
- This fuel quick-closing valve 20 which is not provided with an electromagnetic actuator 22, is always kept closed by means of a spring 21 in the electrically de-energized state. If the rotational frequencies f n1 , f n2 or ⁇ f n1 + ⁇ 1 ⁇ , ⁇ f n2 - ⁇ 2 ⁇ of those on both roller bearings 6 and 7 match, the fuel quick-closing valve 20 is thus kept under electrical voltage and is in the open state ,
