俄罗斯在研制地效飞行器(地空两用飞机、气垫船)方面一直处于世界领先地位。地空两用飞机1965年即研制成功,1974年批量生产的系列地空两用机首次飞行。俄国研制的地效飞行器最初主要用于军事目的,保密甚严。随着军工企业转产民用产品,这种新型交通工具才慢慢见于报端,公诸于世。 Russia has always been a world leader in the development of ground effect aircraft (ground-air aircraft, hovercraft). Air-ground dual-use aircraft was successfully developed in 1965, and a series of air-ground dual-use aircraft was mass-produced for the first time in 1974. The ground-effect vehicle developed in Russia was originally used primarily for military purposes and has strict security. With the transition of military industrial enterprises to civilian products, this new form of transportation is slowly seen in newspapers and made public.
