The present application relates to a kind of high-speed boat with two skids symmetrically arranged on the bottom of deep V planing boat, the extension length and the trim angle of the skid can be adjusted, and two sets of surface propeller propulsion systems are arranged at the stern, the horizontal direction and the vertical direction of the propulsion angle can be adjusted.The present application can maintain the good seaworthiness and rapidity of deep V boat type under high sea conditions.When sailing at high speed under normal sea conditions, the lift and the upward reaction force of surface propeller on the boat body will lift the boat body out of the water, and a very high speed can be achieved.For different sea conditions, manual or automatic control mode can be selected to adjust the sailing state and speed of the boat.The present application has simple structure, small resistance and high speed when skid is sliding, and has good safety, rapidity and energy efficiency ratio under the same power;PID automatic control system is used to ensure the safety, maneuverability and rapidity of the boat;The present application provides a high-speed boat type suitable for various sea conditions for military, police and other industries.

A supercooled large droplet detector capable of accurately and reliably identifying and distinguishing supercooled large droplet icing weather. The supercooled large droplet detector includes a detector base and a detection structure for detecting supercooled droplets in an air flow and for identifying and distinguishing supercooled large droplet icing weather from icing weather, the detection structure having an outer layer of temperature sensor layer, an intermediate layer of electrically heated film layer, and an inner layer of structural base, the electrically heated film layer providing heating energy through a plurality of electrically heated circuits to maintain a uniform temperature on the surface of the detection structure, the temperature sensor layer having a plurality of temperature sensors, and a controller disposed in the structural base, the controller inferring an impact range of a supercooled droplet by temperature changes at a plurality of different locations caused by the supercooled droplet impacting the detection structure, and determining whether the supercooled droplet that was previously impacted was a supercooled large droplet by determining whether the impact range exceeds a critical impact range for a supercooled droplet of a critical size impacting the detection structure.
