A Five-Port Architecture That Measures What Traditional Pitot Tubes Neglect
Windtuner designs its five-hole probe to read the flow field in three dimensions, rather than rely on plain symmetric flow conditions. When the angle of attack or sideslip changes, each pressure port experiences a unique pressure gradient. Windtuner’s algorithms translate these gradients into accurate spatial flow-angle information, dynamic/static pressure, and velocity.
Traditional single-port pitot tubes expose their limit in asymmetric or disturbed flow fields. Windtuner five-hole probes achieve stable, accurate measurement of 3D velocity components, making them indispensable tools for aerodynamic design, UAV flight-control tuning, and calibration wind tunnel tests in research laboratories.
Intelligent Measurement: Aerodynamic Design Meets Embedded Algorithms
Windtuner supplies both standalone five-hole probes for experimental measurements and fully integrated airspeed measurement systems that combine the probe with a customized atmospheric data computer. This flexibility allows clients to specify geometry, mounting, ranges, heating configuration, and interface options to match test benches, wind tunnels, or flight platforms.
Windtuner incorporates three core intelligent technologies into the integrated system:
AI-Driven Low-Temperature Compensation
The embedded algorithm tracks real-time sensor temperature and dynamically adjusts measurement output. This reduces drift under low-temperature and protects accuracy across demanding environments.Smart Anti-Icing with Closed-Loop PID Control
Windtuner develops an intelligent heater using a PID algorithm that modulates its heating curve based on actual airspeed and ambient temperature. The system avoids under-heating that can lead to icing and prevents overheating that may deform small-diameter probe structures.The heating module delivers up to 280 W, achieving 30% higher efficiency than traditional resistance heaters.
Variable-Mach 2D Non-Opposed Linear Interpolation Algorithm
Windtuner draws on extensive calibration wind tunnel datasets to build a knowledge base that corrects flow-angle and velocity outputs under changing Mach numbers. This algorithm maintains stable accuracy even in complex or transitional flow regimes.Selecting a Source Manufacturer: Why R&D, Calibration Capability, and Customization Matter
Five-hole probes demand advanced aerodynamic design, micron-level machining or 3D-metal-printing capability, and rigorous calibration. Partnering with a true source manufacturer profoundly affects measurement accuracy and the reliability of flight-test data.
R&D and Customization Capability
Windtuner designs custom five-hole probes across a wide range of installations and operating conditions. Clients can request structural variations, heater power levels, signal interfaces, mounting geometry, or complete airspeed measurement systems according to their specific requirements. Windtuner supports full customization from geometry to data-processing architecture, delivering solutions tailored to each flight platform or wind-tunnel setup.
Accuracy and Reliability Verification
Windtuner validates every probe in its CNAS-accredited calibration wind tunnel. Probes undergo environmental tests from –35°C to +55°C, with dynamic and static pressure accuracy reaching ≤0.2% FS. AOA and AOS errors remain within ±0.5°, maintaining stable performance across extreme conditions.
A Reliable Partner for Aerodynamic Measurement
Five-hole probes sit at the center of aerodynamic experiments and flight-test evaluations, where the fidelity of airflow data directly impacts design decisions and flight safety. Choosing a manufacturer with strong aerodynamic R&D, calibration infrastructure, and product customization is essential for achieving accurate, repeatable results.
Windtuner delivers an end-to-end portfolio that spans standalone five-hole probes to complete airspeed measurement systems powered by embedded algorithms, smart heating, and rigorous calibration. We at Windtuner stand close with our clients across research institutes, UAV developers, and aircraft manufacturers to run every aerodynamic measurement accurately, reliably, and confidently.
Accurate airflow measurement is the basis behind every stage of low-altitude aviation and aircraft development. Windtuner’s self developed five-hole airspeed probe offers that accuracy. With a design that captures airflow speed, direction, and pressure distribution, the five strategically placed ports on the probe head sense multi-directional pressure changes and feed them into Windtuner’s aerodynamic algorithms to compute critical parameters such as angle of attack (AOA), sideslip angle (AOS), dynamic pressure (Qc), and static pressure (Ps).
