Including flight altitude (Hp), speed (CAS and TAS), Angle of attack (AOA), sideshow Angle (AOS), static pressure (Ps), dynamic pressure (Qc), total atmospheric temperature (TAT), and static temperature (OAT), etc. These data are the basis for the stable flight, precise navigation and various operations of the aircraft. The 5-Hole Differential Pressure Airspeed Probe integrates multiple measurement functions, greatly simplifying the measurement system of the aircraft and improving the overall reliability and efficiency.
From the perspective of structure, the new generation of Airspeed tube systems represented by the Windtuner5-Hole Differential Pressure Airspeed Probe demonstrates a high degree of system integration and engineering optimization. Its core probe is processed from high-strength corrosion-resistant stainless steel and combined with advanced capacitive or strain gauge differential pressure sensors to rapidly convert dynamic air pressure signals into digital electrical signals. This architecture not only ensures the long-term reliable operation of the system in the harsh environment ranging from -35℃ to +55℃, but also guarantees the response accuracy and data consistency under extreme working conditions such as turbulent disturbance and high Angle of attack changes. In cases such as drastic changes in aircraft attitude and sudden changes in payload, real-time data sampling and transmission can still be achieved, providing a high-resolution input basis for the flight control system.
Furthermore, due to its characteristic of having no moving parts, the 5-Hole Differential Pressure Airspeed Probe naturally has the advantages of shock resistance, vibration resistance, and maintenance-free, and is extremely suitable for deployment in unmanned aerial vehicles, hypersonic vehicles, verification aircraft, and flight platforms in complex environments. Compared with the traditional mechanical wind vane system, it is not affected by the "wind vane lag" problem caused by the insufficient thrust of the flow field at low airspeed, nor will it produce dynamic overshoot errors due to structural rotation. This makes it a more ideal solution in multiple scenarios such as flight control feedback, flow field identification, CFD model verification, and even flight safety monitoring.
Today, with the highly intelligent and refined integration of global aviation equipment, the technological evolution of the 5-Hole Differential Pressure Airspeed Probe is not only reflected in measurement accuracy and stability, but also in the data fusion capability and system connection capability it carries. Enterprises like Windtuner, which have the capabilities of independent research and development, customized design and wind tunnel calibration, and wind tunnel laboratories that have passed the CNAS national certification, are capable of conducting high-precision full Angle calibration of the 5-Hole Differential Pressure Airspeed Probe. Ensure that all the equipment leaving the factory can adapt to complex pneumatic environments and provide reliable data support. This technical capability of a full-process closed-loop from design, processing to calibration is precisely the key support for the 5-Hole Differential Pressure Airspeed Probe to achieve high-end aviation testing tasks.
