Airspeed and Wind Shear Measurements with an Airborne CO2 Continuous Wave Laser

Abstract: The Laser True Airspeed System (LATAS) developed by the Royal Aircraft Establishment and Royal Signals and Radar Establishment and installed on the RAE HS 125 research aircraft is described. It has proved exceptionally reliable and rugged. Examples of results are presented including a climb to 43000 ft; flight through a severe thunderstorm wind shear (microburst); pressure error measurements; and signals observed in cloud, heavy rain and from solid objects such as the ground. The paper concludes with some thoughts on other potential applications such as using the sensor for an intelligent autothrottle; for measuring cross-flow velocities; for measuring tyre and ground speeds to save tyre wear; and was a combined air data and ground velocity system for helicopters (including a facility to maintain a steady hover).
