Embodiment Construction
[0024] Such as figure 1 As shown, the propulsion system of the water-air trans-medium craft that can quickly switch the propulsion mode in this embodiment includes a main body bracket 1, a dual output shaft motor shafting 2 is arranged in the main body bracket 1, and a foldable propeller is arranged at one end of the main body bracket 1 3. The other end is provided with a water jet propeller 4, and the foldable propeller 3 and the water jet propeller 4 are connected to an output shaft of the double output shaft motor shafting 2 through a one-way bearing, and the directions of the two one-way bearings are opposite In this embodiment, the double output shaft motor shaft system is used to realize two working modes driven by a single motor. The one-way bearing at the rear end is locked to realize the connection of the water power system when rotating in the opposite direction, and it can quickly switch to the power system suitable for the corresponding medium according to the diff...

The invention discloses an underwater and aerial cross-medium aircraft propelling system capable of quickly switching the propelling mode. The system comprises a main body bracket, a dual-output-shaftmotor shaft system is arranged in the main body bracket, one end of the main body bracket is provided with a foldable propeller, the other end of the main body bracket is provided with a water spraying thruster, and the foldable propeller and the water spraying thruster are connected with output shafts of the dual-output-shaft motor shaft system respectively. According to the system, the dual-output-shaft motor shaft system is utilized for driving two working modes through a single motor, and a power system applicable to a corresponding medium can be quickly switched according to the difference of aerial and underwater mediums, that is to say, the system is switched into an aerial propeller in air, and switched into an underwater propeller under water. The requirements of the power systemfor aerial and underwater propelling and water entry and exit can be met.
Description
technical field [0001] The invention relates to a propulsion system of a water-air cross-media aircraft, in particular to a propulsion system of a water-air cross-media aircraft capable of quickly switching the propulsion mode, which can quickly switch the propulsion mode according to the cross-media requirements. Background technique [0002] With the rapid development of modern equipment technology, the concealment and rapidity of equipment detection make the water-air amphibious vehicle an important strategic equipment, and the propulsion system of the trans-media vehicle determines whether the vehicle can normally travel between the two sides. between the media. At present, most of the commonly used propulsion systems can only be applied to the propulsion of a single medium in the air or underwater, and cannot meet the propulsion needs of cross-medium vehicles. The required propulsion system. Contents of the invention [0003] The technical problem to be solved by th...
