MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202611025728 A) filed by Chandigarh University, Mohali, Punjab, on March 5, for 'self-purging de-icing pitot tube.'
Inventor(s) include Swagatika Dash; Pooja Roy; Shantanu Mandal; and Moniya.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to an improved pitot-static tube system for measuring airspeed or fluid velocity in aircraft, wind tunnels, and industrial flow applications. The system addresses inaccuracies caused by ice formation and debris accumulation in pressure sensing ports. The disclosed invention employs a non-thermal de-icing mechanism based on controlled pressurized gas pulses. The assembly includes an inner pitot tube for total pressure measurement and an outer static tube with radial ports for static pressure sensing, arranged in a precisely defined geometric configuration. Intermittent bursts of compressed gas are directed through internal passages to remove ice and debris without inducing thermal expansion or material fatigue which improves measurement accuracy, reduces energy consumption, minimizes maintenance, and extends service life, ensuring reliable operation under extreme environmental conditions."
