Numerical Simulation on Kinematic Characteristics of Trans-media Aircraft during Water-skipping

doi:10.12382/bgxb.2021.0164

Abstract

Abstract: Inspired by the phenomenon of hydroplaning in life，the flexible skipping motion mode is widely used for trans-media aircraft，which greatly improves the penetration ability of naval weapons. The kinematic characteristics of a trans-media aircraft with complex configuration are studied numerically，and the influence of water-entry parameter on the skipping process of trans-media aircraft over calm water surface is emphatically analyzed. The research results show that the skipping process of trans-media aircraft over water surface can be divided into stable skipping phase and hydroplaning phase，the movement trajectory of trans-media aircraft at the stable skipping phase fluctuates in a sinusoidal pattern，and it is subjected to a large slamming load at every water contact moment. When the water-entry velocity of trans-media aircraft is in the range of 10-55 m/s，the water-entry pitch angle range of the aircraft can increases first and then decreases in the skipping process over water surface with the increase in the entry velocity. When the entry velocity is 30 m/s，the effective range of the water-entry pitch angle of the aircraft is from -8° to 10°.The greater the water-entry velocity is，the greater the slamming load is，the more the number of stable skipping is and the farther the stable skipping distance of the aircraft is. When the pitch angle of water-entry is from 0° to -5°， the trans-media aircraft has the most stable skipping times over the water surface，the longest skipping distance，and the most stable skipping attitude.

Key words: trans-mediavehicle, skipping, slammingload, motioncharacteristic
