5-Hole Differential Pressure Airspeed Probe

Five-hole differential pressure pitot tube is a high-performance measuring device specially designed for low-altitude aircraft, which can provide data of flying altitude (Hp), speed (CAS and TAS), angle of attack (AOA), sideslip angle (AOS), static pressure (Ps), dynamic pressure (Qc), total atmospheric temperature (TAT) and static temperature (OAT) for aircraft.
The adaptive PID algorithm dynamically adjusts the heating power, and matches the optimal temperature rise curve according to the real-time airspeed and the ambient temperature to prevent the probe from freezing or overheating. (9~30)VDC wide power supply, the maximum heating power is 280W, using PWM pulse width modulation technology, saving energy by 30% compared with conventional resistance heating.
Based on the aerodynamic principle, a multi-aperture five-hole differential pressure pitot tube probe with variable cone angle is pioneered, which can effectively solve the problem that the air inlet is easy to block when the aircraft flies at low speed while ensuring the measurement accuracy, and escort the flight safety accurately.
