Rotor wing underwashing visual simulation method and system based on offshore flight

Abstract

The invention discloses a rotor wing underwashing visual simulation method based on offshore flight. The method comprises the steps that S1, texture pictures of water surface ripples in the underwashing process of a helicopter rotor wing are acquired; S2, the position of a helicopter in a virtual scene is acquired, the local coordinates of the texture pictures are converted into projection coordinates, and the collected texture pictures are rendered to the virtual scene in a dynamic effect mode according to the projection coordinates; S3, an OSG is called to render a particle simulation system of an engine, and lifted water mist is added. The invention further provides a rotor wing underwashing visual simulation system based on offshore flight. According to the rotor wing underwashing visual simulation method and system based on offshore flight, the visual effect of the helicopter close to a sea surface can be truly simulated, and the adaptive capacity of a pilot for executing low level tasks can be enhanced.

Description

technical field [0001] The invention relates to the technical field of visual simulation, in particular to a method and system for visual simulation of rotor downwash based on near-sea flight. Background technique [0002] The visual simulation system is used to simulate the scene outside the cabin, providing a realistic scene outside the cabin, and is an important part of the flight simulator. The image quality and performance of the image generation equipment in the visual simulation system are directly related to whether the pilot can make a correct judgment on the scene, which is of great significance. [0003] The development of the marine module in the visual simulation system occupies an important position, and the development of this field in our country is still in the initial stage. Regarding the helicopter rotor downwash, the movement of the rotor, part of the air is attached to the surface of the rotor, and the air is also compressed. The pressure on the upper s...

AI Technical Summary

Problems solved by technology

[0004] Therefore, the existing flight simulator visual simulation system is relatively weak in the development of marine modules, and the development of special effects (such as rotor wash-down) close to the sea is still blank, which seriously affects the pilot's visual interpretation when approaching the sea. Subject training in special circumstances (such as broken altimeter) cannot be carried out
