Spanish SME offers more accurate measurements for the aeronautical industry through photonic solutions
Summary:
A Spanish (Basque) SME specialized in the development of photonics technology for different industrial fields offers innovative technology to make more precise measurements in the aeronautical industry. The company looks in the first instance for a commercial agreement with technical assistance. But it is also willing to cooperate under a license agreement, research cooperation agreement or technical cooperation agreement.
Description:
The Spanish company is a spin-off company from the University of the Basque Country whose mission is to apply customised photonic solutions to all kinds of industrial processes. In aeronautics, the main product is a system for monitoring turbines and compressors based on the measurement of Tip Timing (TT) and Tip Clearance (TC).
They have already available optical probes and the optoelectronic equipment for the measurement of Tip Clearance and Tip Timing in turbines, compressors, and fans. These parameters are related to the performance and mechanical behaviour of the motor blades.
The distance between the end of the blades of a turbine and its casing is known as TC. This parameter is related to the efficiency of the turbine/compressor, which increases as the TC decreases. Therefore, an accurate system for measuring this distance allows the air flows through the turbine to be adjusted to a minimum without producing useful work, achieving aeronautical engines with lower fuel consumption, and consequently, more economical and ecological.
On the other hand, the TT is a technique that enables evaluating the amplitude and frequency of the vibrations of the blades from the arrival time of each one of them to the position in which the sensor is located. Once the amplitude and frequency of vibration are known, the dynamic behaviour of the turbine blades can be characterised, and systems for monitoring the amplitude and frequency of vibration are known, the dynamic behaviour of the turbine blades can be characterised, and systems for monitoring the turbine´s structural health based on both parameters can be designed. Thus, ensuring the correct operation of the engine, predicting possible failures due to blade fatigue or damage to the blades due to impacts (birds, ice, ...).
The optoelectronic equipment includes up to 6 modules. Each module has 2 outputs for the data acquisition system and can be configured with 1 or 2 lasers. This equipment can be configured to measure TC at three different points or combine a single measurement point for TC with 4 probes for TT.
Thus, the company is looking primarily for a commercial agreement with technical assistance, where the client will have the technology implemented in its factory and the company will give them support every time it is needed. The purpose is to develop this solution and to validate it for the market. Another acceptable cooperation types would be license agreement, research cooperation agreement or technical cooperation agreement.
Advantages and Innovations:
The optoelectronic system will allow to measure TT and TC parameters with greater precision and in real-time. Currently, there are different technologies for these measurements, but this system based on optical sensors increases the performance of the systems used to date.
Regarding TC, sensors have demonstrated an accuracy of 12 µm in real operating conditions, improving the performance of capacitive, inductive, or electric shock sensors. Furthermore, they all require the turbine blades to be made of an electrically conductive material, thus reducing their application to the study of new materials in the manufacture of turbine blades, such as ceramics.
Within the optical sensors, there are different technologies used in the measurement of TC, such as the Doppler effect or interferometry. However, sensors based on light power have proved to be the simplest, most robust, and economic.
The most widely used sensors for studying the vibrations of the blades are strain gages. Despite being widely used its drawbacks are not few. The main ones are its laborious installation as far as cabling is concerned, the need for telemetry or a slip ring to transmit the obtained data and that the measurement is made with contact with the blade. All these inconveniences are avoided when using the TT processing technique. The optical sensors used for this analysis offer the following advantages over other sensors used for this purpose (mainly capacitive and inductive): insensitivity to electromagnetic interference, low weight, and size, great sensitivity, resolution, and bandwidth.
In addition, the optical sensors that make up the system allow TC and TT measurements to be carried out using the same sensor, with the consequent savings in both installation-calibration times and economic expense. They can also be designed with different operating ranges, so they are perfectly adjusted to the particular conditions of each turbine, compressor, or fan.
