Experimental facilities / Experimental facilities for the aerospace industry
WTtech.CZ manufactures experimental facilities and test equipment for many industries including the most demanding ones, such as the aerospace industry. Our test equipment and components, as well as their implementation at customer sites, meet the highest quality, safety, and maximum test reliability requirements. Recently, we have completed test equipment to measure the performance and reliability of aircraft engine components, as well as hydraulic and fuel systems. Testing these devices is often necessary to verify the safety and efficiency of aerospace applications.
We supply experimental facilities developed and designed by us with modifications and construction completely tailored to customer conditions and requirements. Apart from the facilities, we offer a comprehensive service, including delivering all equipment, programming the measurement and control software, project management, preparation of research projects, and expert consultation.
Construction at WTtech.CZ is conducted exclusively in a 3D CAD system using Creo software, which enables detailed design and modeling of all testing facility components. The design data is stored and managed in the Windchill PDM system, ensuring efficient product lifecycle management and easy access to all necessary information.
Design optimization includes FEM (Finite Element Method) and CFD (Computational Fluid Dynamics) analyses. These analyses allow the simulation of the mechanical and fluid behavior of components before they are manufactured, resulting in high product quality and reliability.
WTtech.CZ control and measuring systems are based on the PLC (Programmable Logic Controller) technology and the measurement of selected parameters by industrial computers. This guarantees the resulting products’ exceptional accuracy and reliability.
Testing facility control and measurement is usually implemented in the LabVIEW user interface. This enables efficient test automation, minimizes the need for human intervention, and increases efficiency and measurement accuracy while offering intuitive visualization and analysis of measured data.
This device is designed to ensure maximum cleanliness in the gearboxes’ internal oil reservoirs. This uniquely designed equipment uses an oil flushing station to wash the complete gearbox assembly. During this process, the gearboxes are washed with a special oil, which ensures the impurities are effectively washed out and subsequently captured in the filter. The gearbox is angularly adjustable and tilted in 2 axes. It is powered to simulate normal operation. The temperature and oil properties are controlled according to specific customer requirements.
This equipment performs run-in and flow measurements of pumps under pre-set hydraulic resistances.
Access to the cabinet’s interior is provided by a door at the rear and on the right side; the left side contains a separate control cabinet with PLC, motor inverter, and other electrical components. The control panel with controls, including a foil-protected touchscreen display with a synthetic oil-resistant film, is located at the front of the equipment.
The test procedures are fully automated and PLC controlled, allowing the pressure conditions of installing the pump into the engine to be simulated. The hydraulic resistances are adjustable and, together with the speed pump speeds, the oil flow can be measured accurately, ensuring high test accuracy and repeatability.
Pumps are tested by changing in hydraulic resistance at pre-set speeds. Every time the speed setting and hydraulic resistances are changed, the flow through the pump or pump stage is measured. Depending on the pump type tested, various parts of the hydraulic system differing in their clearance both at the inlet (suction) and at the outlet (discharge) are used. The measurement is fully automated, which guarantees high quality and reliability of the entire process. The system also allows the generation of detailed measurement reports, which are crucial for maintaining the quality system and for accurate evaluation of the tested pumps’ performance.
Its high flexibility and automation make the test equipment for hydraulic pump testing a key tool for verifying the performance and reliability of hydraulic systems in various applications.
The WTtech.CZ oil test station is designed for measuring oil flow through aircraft engines. The purpose of the device is to provide accurate data on the oil flow rate. All impurities are captured by a filter, ensuring maximum cleanliness of the engines’ internal oil compartments.
The intuitive touchscreen display on the station’s top surface enables easy control. All processes, including flushing, are fully automated and PLC-controlled. In addition, the touch screen is protected by a synthetic oil-resistant film.
The oil test station is a key tool for ensuring optimal performance and safety of aircraft engines and a source of essential information for maintenance and service.
This equipment is designed to measure the aerodynamic characteristics of propellers with a maximum diameter of 1,8 m. The device has a power input of 110 kW and reaches up to 3000 RPM. It allows precise measurement of thrust, torque, power, and propulsion efficiency of both adjustable and fixed propellers.
The measurement and control system automatically processes the data and displays the results online using its characteristic curves, providing an instant overview of the performance and efficiency of the propellers under different operating conditions.
The device is capable of measuring both static and dynamic thrust in flight simulation speeds in a wind tunnel. This allows complex propeller tests including not only their basic characteristics but also their behavior at different flight speeds.
The high degree of adaptability and accuracy of the measurements makes this device an essential research and development tool in the field of propeller aerodynamics.
