Icing of the flying wings is a serious hazard, which destroys the smooth flow field on the surface of the aircraft, increases the flight resistance, and reduces the reliability of flight control and the lift force of the aircraft. As the power increases to compensate for the extra drag and the flight angle of attack increases due to nose lift taken to maintain altitude, the critical angle of attack decreases, the aircraft stalls at higher speeds or at lower angles of attack than normal, and the maneuverability and stability deteriorates, possibly falling into an uncontrolled and unrecoverable roll or pitch condition, particularly causing the maneuverability of the aircraft to be out of control during take-off and landing conditions, resulting in serious flight accidents.
