Measurement of high-precision turbine blades

For the quality assurance of its high-precision turbine blades, Hyatech on close cooperation with WENZEL. The professional measurement solutions are used there for multi-dimensional measurements in aerospace and industrial manufacturing. Hyatech is an up-and-coming private company from Wuxi, China and is convinced “that WENZEL's highly accurate measuring devices undoubtedly make Hyatech's product quality even more competitive. ”

The high-tech company specializes in the research and development, production and sale of key parts for aircraft engines. These include high-performance components such as compressor blades, rotating components and components such as blisks, housings, turbine and compressor discs, rectifiers and rotor components.

Ease of use for software and hardware

The engine is the “heart” of an aircraft, so the rotating parts and structural elements such as the engine blade, blisk, turbine disk and housing are the “muscles and meridians*.” As one of the most important parts of an engine, the geometry of the blade has a direct influence on aerodynamic performance during operation. The characteristic parameters of the engine, the compressor charge ratio, the turbine speed, etc. are closely linked to the shape and position of the blade. Measuring the geometry of the engine blade is therefore particularly important.

Hyatech has grown very fast in recent years. With the continuous increase in production capacity and the increasingly complex product structure, the need for measuring devices has increased to keep pace with development. Hyatech has chosen WENZEL from among many providers of measurement solutions, as Leiyu Zhang, engineer at Hyatech, explains: “WENZEL has a long industrial history and their coordinate measuring machines are made of granite structures. As far as measurement software is concerned, WENZEL's modular design is very convenient for future upgrades. Hyatech is already using two WENZEL measuring machines, which also take into account the simple and ergonomic usability for the user. For this reason, Hyatech finally opted for the WENZEL LH 2015 coordinate measuring machine. ”

Ø Measurement of complex product structure

Ø Measurement of the blade profile of the blisk, including the gearing and surface roughness of the turbine blade profile

The measurement and determination of the processing accuracy is particularly important due to the higher requirements for the blade profile size and the position accuracy of the blisks, the uniform arrangement of the blades in the circumferential direction on the blisks and the very small air flow channel between the blades and a challenge for measurement. The five-axis LH 2015 measuring machine from WENZEL perfectly solves the above challenges. The most attractive point of this solution for Leiyu Zhang is “the evaluation and measurement of the blade profile and the secondary development and application of the transmission. ”

The LH 2015 is a high-speed and high-precision portal CMM that supports tactile, scanning and optical sensors. The measurement ranges of X, Y and Z are 2000 mm, 4000 mm and 1500 mm, and the load capacity is 6,000 kg, which means that the entire blisk as well as large and complex structural elements can be easily accommodated.

Compared to previous devices, WENZEL's solution offers an unusual new experience, as Leiyu Zhang confirms: “First, WENZEL has a lot of experience in measuring blisks and turbine blades. Since the structure of Blisks is complex and the surface is also difficult to measure, WENZEL is absolutely competitive when it comes to evaluating and measuring blade profiles. Second, WENZEL offers a measurement module for gears, which has been assembled for some special components of components and is very convenient to use. Finally, WENZEL offers a roughness measurement for blade profiles that has been improved in terms of time and efficiency; and the form of the measurement report tends to be standardized.” With the WENZEL LH 2015, a whole new world has opened up for Hyatech that can meet future challenges and opportunities.

Leiyu Zhang also comments positively about WENZEL's service: “We have been working with WENZEL for many years. WENZEL is always ready to answer any questions you may have about software and hardware. For example, the service technician always arrives on site the next morning if there is a problem that occurred in the afternoon of the previous day. In addition, WENZEL technicians have good behavior and solve problems efficiently. We would like to continue this type of cooperation with WENZEL in the long term. ”
