In Russia, a patent has been registered for an unusual universal "Saturn" device capable of operating in the atmosphere, space, and aquatic environment. The development includes vertical take-off and landing, submersion and surfacing, as well as manned and unmanned modes, the author of the project is Vladimir Panchenko.
The structure is built around an ellipsoidal fuselage with ring modules. Rotor engines of external working fluid supply will be placed in the gap between the body and the ring.
The units provide lift, stabilization, and control over roll and pitch. Additional engines on the sides are responsible for horizontal movement and maneuvers.
The power plant is located in a sealed compartment and allows for different power options — from external combustion chambers to alternative schemes. Speed and direction are controlled by changing the pressure on the rotors with automatic adjustment via proximity sensors.
The ring compartments are designed to accommodate equipment, fuel, and crew. According to the engineer's idea, this architecture expands the capabilities of the device for transport and research tasks.
