    • UAV Icing: Ice Accretion Experiments and Validation 

      Hann, Richard (Journal article; Peer reviewed, 2019)
      Atmospheric icing is a key challenge to the operational envelope of medium-sized fixed-wing UAVs. Today, several numeric icing codes exist, that all have been developed for general aviation applications. UAVs with wingspans ...
    • UAV Icing: Icing Cases for Validation of Path Planning Method 

      Cheung, Michael; Hann, Richard; Johansen, Tor Arne; Stovner, Bård Nagy (Peer reviewed; Journal article, 2023)
      As part of the complete solution to deal with atmospheric in-flight icing on unmanned aerial vehicles (UAV), a path planner is a valuable tool for finding an optimal path for accomplishing UAV missions. When considering ...
    • UAV Icing: Intercycle Ice Effects on Aerodynamic Performance 

      Wallisch, Joachim; Hann, Richard (Peer reviewed; Journal article, 2023)
      Atmospheric in-flight icing poses a challenge to all aircraft including unmanned aerial vehicles (UAVs). Aircraft should avoid icing conditions unless they have ways of mitigating the negative effects of icing, e.g., if ...
