CTOnews.com November 5 news, According to Harbin Engineering University official news, Two named "Longgong 1" and "Longgong 2" Submersible air cross-medium vehicles recently in Wuchang City, Heilongjiang Province Longfengshan Reservoir successful test flight. Two "small planes" dive underwater one after another, arrive at the designated position in dozens of seconds, and fly out of the water lightly after completing the task.

CTOnews.com learned that the two submarine-space transmedia vehicles were built by Harbin Engineering University's National Key Laboratory of Underwater Robot Technology over a year. The two aircraft adopt fixed wing and folding wing structure respectively, both of which can quickly cross the water-air medium, fly stably in the air, navigate covertly underwater, and the whole process is fully autonomous without manual control.

▲ "Longbow 1" cross-domain attitude| According to the same introduction from Harbin Engineering University, the wing size after deployment is 2.3m × wingspan 2m and 1.9m × wingspan 2.5m respectively. It can not only switch freely in the air, water surface and underwater, but also bear a load of 1 kg and dive depth of 100m. Through the high-definition camera and digital radio station, the interface observation between atmospheric boundary layer and ocean boundary layer can be completed.

▲ "Longbow 2" cross-domain attitude picture Among them, in order to improve the cross-medium capability, the team specially designed folding wings for "Longbow 2," which also means that the stable attitude of the aircraft is more difficult to control. In order to stabilize the flight of Longbow 2, its folding structure has been changed as many as nine versions. In the test,"Longbow 2" overall water, wing deployment, successful takeoff, the whole process less than 6 seconds.
