FI91953C - Ways of installing an ice sensor transducer wire in aircraft - Google Patents

Description

91953

The invention relates to an ultrasonic propagation method according to the preamble of claim 1, based on a metal wire-based method for installing a sensor wire or a device for mechanically mounting a sensor wire. The sensor part of the split sensor comprises a metal sensor wire mounted on the surface 10 requiring split monitoring, which has an ultrasonic transmitter at one end and an ultrasonic receiver at the other end.

The problem with this method using a metal wire sensor is that in aircraft, a metal wire with good sensor properties is aerodynamically as such and mounted on a surface requiring monitoring at several sites. other mechanical stress, such as a story or stepping.

Using the mounting method 25 described in this patent application, the wire sensor can be successfully used in objects requiring aircraft and monitoring, such as wing leading edge solos, wing, rotor and stabilizer leading edge, and engine intake ring leading edge -afloat. In order to achieve these objects, the installation method is mainly characterized by what is set forth in the appended claim 1 in the characterizing part 35 thereof.

The invention is illustrated in the following description by reference to the figures of the accompanying drawing.

The mechanical mounting method of the wire sensor according to the invention is characterized in that the wire sensor is mounted in a groove providing mechanical lateral support and aerodynamic shape protection, which is obtained by mounting flat wire-like supports on both sides of the wire (Fig. 1) which are glued or otherwise attach to the substrate requiring inspection, or make a groove approximately 10 wire wide and deep in the substrate (Figure 2), or mount the sensor wire between the plates mounted on the butt seam of the mounting base by machining the gap between the plates approximately wire wide if necessary (Figure 3).

In order to keep the sensor wire in its groove as firmly as possible, the sensor wire is shaped curved before installation so that the wire preload is pressed against the mounting base 20 during installation or the wire is tensioned longitudinally when installed. In this case, the sensor wire does not necessarily need any other supports that may interfere with the sensor operation than the fastening of the sensor wire at the flanges of the mounting base at the ultrasonic transducer and the ultrasonic receiver and the aerodynamic and hydrodynamic forces or machine vibrations.
