Abstract
The present invention features a technique and system for achieving sufficiently stable, thick liquid films on an aircraft surface during a rain storm in flight, wherein such stable and thick films can be measured to determine liquid water content (LWC) in the air, and (by known correlation) rain fall rate. Rainfall impinging upon an airflow surface of an aircraft, such as a wing portion, is gathered and confined within a weir-like structure. The flow of the rain is constricted within this device to increase the film thickness and reduce shear between air and liquid boundaries, whereby a stable film surface for measurement is provided.
