Multi-function Air Data Probes for UAVs and aircraft

Aeroprobe Multi-function Air Data Probes provide accurate aerodynamic pressure measurements for unmanned aerial vehicles (UAVs), experimental aircraft and flight testing applications. Combined with a compatible Micro Air Data Computer (μADC), these probes provide real-time information about airspeed, altitude, angle of attack (AoA) and angle of sideslip (AoS).

Unlike conventional air data booms with mechanical pitch and yaw vanes, Aeroprobe's multi-function probes determine the airflow direction without moving parts. This reduces mechanical complexity, weight and response delays associated with moving vanes.

The probes feature five pressure ports at the tip and a static pressure ring. Their compact design makes them suitable for aircraft where installation space, weight and aerodynamic interference must be kept to a minimum.

Available probe configurations

Straight air data probes

Straight probes position the measurement tip directly in the airflow. They are suitable for installations where the probe can be aligned with the incoming flow, including flight test booms and wind tunnel applications.

L-shaped air data probes

L-shaped probes use a curved geometry to position the measurement tip away from the mounting shaft. This helps reduce airflow obstruction downstream of the probe and provides additional installation flexibility.

Strut-mounted air data probes

Strut-mounted probes are designed for integration into aircraft structures. Their aerodynamic mounting configuration helps reduce drag and flow interference while providing a practical installation solution for UAVs and aircraft.

Designed for demanding flight applications

Aeroprobe Multi-function Air Data Probes are manufactured from stainless steel and are available with optional features for specific operating conditions.

An internal heater can provide icing protection, while an optional integrated Total Air Temperature (TAT) sensor enables additional temperature measurement.

The standard measurement configuration supports angle of attack and sideslip measurements up to ±20°. Extended-angle configurations are available for applications requiring measurements up to ±40°, subject to the selected probe and compatible air data computer.

Applications

Aeroprobe Multi-function Air Data Probes are suitable for UAV development, experimental aircraft, flight testing, aerodynamic research and flight control system integration.

Their compact design and ability to measure multiple flight parameters make them particularly useful where conventional air data booms are too large or heavy.

Selecting the right Aeroprobe air data probe

The appropriate probe configuration depends on the aircraft geometry, expected airspeed, angle-of-attack range, environmental conditions and installation requirements.
