Design And Evaluation Of Sensor Housing For Atmospheric Boundary Layer Profiling Using Multirotors, Ashraful Islam

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

Traditional configurations for mounting Temperature–Humidity (TH) sensors on multirotor Unmanned Aerial Systems (UASs) often suffer from insufficient radiation shielding, exposure to mixed and turbulent air from propellers, and inconsistent aspiration while situated in the wake of the UAS. Consequently, atmospheric boundary layer profiles that rely on such configurations are bias-prone and unreliable in descent. This thesis describes the evolution of a novel sensor housing design over three iterations. The sensor housing is designed to shield airborne sensors from artificial heat sources and artificial wet-bulbing while pulling air from outside the rotor wash influence. The housing is mounted above the propellers …
