Currently, there is no sensor for assessment of an aircraft engine’s exposure to dust and particulates. Hal Technology developed sensor can measure real-time dust loading and is potentially capable of material identification. The sensor can be integrated into many aircraft engines and engine health management systems and can be used to both avoid regions with high dust levels and perform condition-based maintenance. Hal Technology specializes in providing advanced technology solutions for environmental sensing applications. Our goal is to transition this technology to an OEM sensor manufacturer with flight qualification experience for eventual integration into government and prime contractor engine health management systems. The initial target engine platforms are the GE T-700, AE1107C or F-135. This particle sensing technology is applicable to both gas and liquid.
