Windtuner Five-Hole Differential Airspeed Probe
Professional Precision Defines Strength
The Five-Hole Differential Airspeed Probe is designed specifically for low-altitude aircraft, providing precise measurements of key parameters such as airspeed, altitude, and attitude angle. Its unique variable Mach number 3D non-coaxial linear interpolation algorithm, waterproof anti-icing structure, and variable cone-angle probe design make it a critical tool for enhancing flight performance and safety.

High Integration and Multifunctional Design
Windtuner's Five-Hole Differential Airspeed Probe features a highly integrated structure, the heater, pressure sensors, temperature sensors, and drainage modules are combined within a single compact body. With an integrated design, the probe offers smaller volume, faster response, and higher reliability. The total pressure and static pressure modules are arranged with precision to ensure rapid and accurate dynamic pressure measurement even in complex airflow conditions.
The probe is equipped with intelligent temperature compensation and anti-icing functions. Using a PID-based control algorithm, the system dynamically adjusts heating power to match optimal heating curves based on real-time airspeed and ambient temperature, preventing both icing and overheating. With a wide 9–30VDC power supply range and a maximum heating power of 280W, it maintains measurement stability even in extremely cold environments while achieving approximately 30% higher energy efficiency compared with traditional resistive heating designs.
Windtuner also integrates multiple proprietary innovations into the probe's design. The AI-based high and low-temperature compensation algorithm automatically corrects temperature-induced measurement errors, ensuring more accurate and stable aerodynamic pressure data. The variable Mach number 3D non-coaxial linear interpolation algorithm, built upon an extensive aerodynamic database from experimental data, delivers high-fidelity aerodynamic computation across varying Mach numbers and attitude angles, ensuring the reliability of airspeed and angular measurements.
Windtuner's calibration expertise further reinforces product accuracy. Windtuner operates three self-built calibration wind tunnels(subsonic, low-speed, and supersonic), all accredited by CNAS. Each Five-Hole Differential Airspeed Probe undergoes rigorous flow field recovery and precision validation before delivery, guaranteeing performance that meets international standards.
