Sea and air amphibious propeller

Abstract

The invention provides a sea and air amphibious propeller. The propeller comprises a ducted propeller stator, air propellers, air propeller rotors, ducted propellers and ducted propeller rotors, wherein a group of magnets is fixed on the air propeller rotors and the ducted propeller rotors respectively, the air propeller rotors and the ducted propeller rotors rotate coaxially and are nested to thesame ducted propeller stator, and two coils corresponding to the air propeller rotors and the ducted rotors respectively are embedded into the ducted propeller stator. The air propellers are used foraerial propulsion, water propellers are used for underwater propulsion, and the both can work independently. During underwater propulsion, the air propellers are folded back and rotated at a lower speed to eliminate the resistance to the air propellers, and the shaftless ducted propellers work to generate propulsion. In the air, the air propellers are unfolded and rotate to generate propulsion, and the ducted propellers assist the operation. The shaftless ducted propellers have good propulsion performance under water, the air propellers are suitable for working in the air, and the air propellers are combined with the shaftless ducted propellers to realize efficient propulsion and free switching under water and in the air.

Description

Technical field [0001] The invention relates to an amphibious propeller, in particular to an amphibious propeller suitable for sea and air. Background technique [0002] Existing amphibious vehicles include amphibious amphibious vehicles, land-air amphibians and land-air amphibians. The development of sea-air amphibious vehicles that can navigate both in the air and underwater has been stagnant. The most important technical limitation is the development of propulsion equipment. The air propeller has good propulsion performance in the air, but has low thrust and low propulsion efficiency under water, while the water propeller has good propulsion performance under water but is not suitable for working in the air. Therefore, designing a propeller with good propulsion performance in the air and underwater is of great significance to the development of sea and air amphibious vehicles. Summary of the invention [0003] The purpose of the present invention is to provide a sea and air am...

[0002] The existing amphibious vehicles include amphibious vehicles and land-air amphibious vehicles, but the development of sea-air amphibious vehicles that can navigate both in the air and underwater has been stagnant. The main technical limitation is the development of propulsion equipment

The air propulsion performance is good in the air, but the thrust is small and the propulsion efficiency is very low underwater, while the water propeller has good propulsion performance underwater but is not suitable for working in the air at all
