Novel cross-domain aircraft

The invention aims at providing a novel cross-domain aircraft which comprises an aircraft hull, a cross-domain dual-purpose device is arranged in the middle of the aircraft hull and comprises a radial rotating shaft, the radial rotating shaft is installed on the aircraft hull, tilting mechanisms are installed at the two ends of the radial rotating shaft and connected with telescopic variant wings, and the telescopic variant wings are connected with the aircraft hull. The telescopic morphing wings comprise inner wings, containing cabins and outer wings from inside to outside, the inner wings are connected with the containing cabins, the outer wings are located on the outer sides of the containing cabins or retracted into the containing cabins, and a water ballast space is arranged below the front portion of the aircraft hull. The aerial cross-domain dual-purpose device can meet the navigation requirements under different working conditions of the water domain and the air domain, and the telescopic wings in the
