The application relates to a multifunctional
airbag system for assisting a cross-medium vehicle to quickly
cross media, which is suitable for a rotary-wing cross-medium vehicle and comprises an
airbag buffer device, an
airbag ballast device and a multi-airbag
air volume unified control module. The airbag buffer device is arranged at the head of the cross-medium vehicle, the airbag
ballast device is arranged at the middle section of the cross-medium vehicle, and the multi-airbag
air volume unified control module is arranged at the
tail of the cross-medium vehicle. The cross-medium vehicle is provided with three functions of
underwater attitude adjustment, high-speed
water entry buffering and rapid water exit assisting, the airbag
ballast device replaces a traditional ballast water
system, the inflation amount of the ballast airbag and the
propeller power are controlled, and the functions of the cross-medium vehicle in
underwater attitude adjustment, such as floating, diving and rotating, and the function of zero-
energy consumption suspension in water can be realized.
