COMBINED SUBMERSIBLE VESSEL AND UNMANNED AERIAL VEHICLE

摘要

A combined submersible vessel and unmanned aerial vehicle preferably includes a body structure, at least one wing structure, at least one vertical stabilizer structure, and at least one horizontal stabilizer structure. A propulsion system is coupled to the body structure and is configured to propel the flying submarine in both airborne flight and underwater operation. Preferably, the propulsion system includes a motor, a gearbox coupled to the motor and configured to receive power generated by the motor and provide variable output power, a drive shaft coupled to the gearbox and configured to transfer the variable output power provided by the gearbox, and a propeller coupled to the drive shaft and configured to accept power transferred to it from the drive shaft. The propeller is further configured to rotate and propel the flying submarine in both an airborne environment and in an underwater environment.

主权项

1. A method for operating a flying submarine, comprising:
providing a rocket propulsion system to cause exhaust propulsive matter from the rocket propulsion system to propel the flying submarine; flooding a ballast tank with water; placing the flying submarine at an appropriate water exiting depth; accelerating the flying submarine to about a maximum forward velocity with a propeller propulsion system; placing the flying submarine at a water exit angle; firing the rocket propulsion system at or just below a water-air interface, thereby providing an exhaust propulsive matter from the rocket propulsion system and propelling the flying submarine to a water exit velocity; unfolding one or more wing structures on the flying submarine to a flying position just at or above the water-air interface; and reversing the propeller propulsion system to operate the propeller in an airborne mode.
