Shi Yajun from the Chinese Research Institute of Ship Science and his team have designed a new aerial vehicle that can be utilized for delivering supplies to islands and beaches or conducting search and rescue missions. The prototype has completed 30 tests over the sea, as reported by Interesting Engineering on April 10. The machine is equipped with a propulsion engine that allows it to move above the water’s surface, while its wings assist in airborne travel.
The Ground Effect Vehicle (GEV) utilizes the aerodynamic phenomenon that reduces drag experienced by an object approaching a surface to achieve lift and enhance efficiency. The air cushion between the surface and the object allows it to generate lift at lower speeds. A famous example of this type of vehicle is the ekranoplan from the former Soviet Union, which could fly just a few meters above the water with a wingspan of 70 meters. The ekranoplan was designed to transport people and equipment above the water, reaching speeds of up to 400 km/h.
According to Science and Technology Daily, the new aircraft can fly for 6 hours continuously at a speed of 240 km/h. The vehicle has a total takeoff weight of 4.5 tons and can carry 12 passengers. “Compared to seaplanes or previous generations of winged ships, this machine has high wave resistance, ensuring year-round operations and safety in rough seas,” Shi stated.
The research team estimates that the vehicle can move 20 times faster than boats on the water. It can quickly reach accident sites and stay nearby for extended periods while conducting search and identification activities using onboard detection systems. The aircraft can then hover over the target, deploying rescue equipment and emergency supplies. It can also transport injured individuals to medical facilities. This ground effect vehicle will play a crucial role in the high-speed transport network between Hainan Island and other islands.
