Ophir proposes to develop a multifunction, low-cost lidar capable of accurately measuring kinetic air hazards, and air data, simultaneously. The innovation is providing a single sensor that has dual-use functionality air data measurement and kinetic air hazard detection in a package that is easily integrated onto commercial aircraft. Conventional air data systems provide critical information to the aircraft for safe flight, but there are vulnerabilities, as evidenced by the recent Air France accident. A more robust air data system for flight controls on aircraft is needed particularly to measure airspeed in icing and severe weather conditions. This proposed sensor also measures air hazards which impacts the safety of air traffic and smoothness of ride; decreases fuel consumption and incidence of encounters with turbulent events on aircraft. The Phase I effort entails the system requirements determination, determination of optimal dual-use sensor, prototype design, range and accuracy expectations for each of the lidar modes, and preliminary design of the Phase II prototype. This technology is a TRL 2 with the intent of reaching TRL 3 by the end of this program. Phase II consists of a sensor demonstration in a representative flight environment (TRL 5).
