Problems solved by technology

[0003] However, the current ships still use the propeller propulsion system. Since the hydraulic power of the propeller propulsion system is a spherical scattering of a three-dimensional field, the thrust is relatively scattered and the directionality is poor. Moreover, the surface size of the propeller is large and its own resistance is large. These defects lead to the failure of the propulsion system. The power utilization rate is not high, so that the speed of the ship cannot be increased

Embodiment Construction

[0015] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] see figure 1 As shown, the present invention is a turbo water jet ship propulsion system, which is installed on the lower part of the hull 7, which includes a wave inlet pipe 2, an engine 4, a turbine 3, a transmission 5, a transmission system 6 and a water jet 8, wherein , one end of the turbine 3 is connected to the wave inlet pipe 2, and the other end is connected to the water spray port 8. The engine 4 drives the turbine 5 through the transmission system 6 and the gearbox 5, and the wave 1 enters from the wave inlet pipe 2 and impacts the turbine 3, and the engine 4 and the wave 1 jointly drive the turbine 3 to rotate to generate a high-speed water flow 9, the high-speed water flow 9 is ejected from the water spout 8 so as to propel the ship 7 to advance at a high speed.

[0017] The working principle of the turbine water...

Abstract

The invention relates to a turbine jet-type ship propulsion system which comprises a wave inlet pipe, an engine, a turbo, a gearshift, a transmission system and a jetteau, wherein, one end of the turbo is connected with the wave inlet pipe and the other end is connected with the jetteau; the engine drives the turbo through the transmission system and the gearshift; waves flow into the turbo through the wave inlet pipe and impact the turbo, both the engine and the waves drive the turbo to rotate to cause high-speed water flow which is jetted from the jetteau to boost the ship to move forward at a high speed. The turbine jet-type ship propulsion system can ensure the ship to have high navigation speed and even ultrasonic cruising speed and can realize high usage of energy by making full use of the energy of waves.

Description

【Technical field】 [0001] The invention relates to a ship propulsion system, more specifically a turbine water jet ship propulsion system, which is used in ship propulsion occasions. 【Background technique】 [0002] The propulsion system of the aircraft has changed from the propeller propulsion system to the turbojet propulsion system, which has greatly improved the maneuverability of the aircraft, and the speed has undergone a qualitative leap from subsonic to supersonic. [0003] However, the current ships still use the propeller propulsion system. Since the hydraulic power of the propeller propulsion system is a spherical scattering of a three-dimensional field, the thrust is relatively scattered and the directionality is poor. Moreover, the surface size of the propeller is large and its own resistance is large. These defects lead to the failure of the propulsion system. The power utilization rate is not high, so that the speed of the ship cannot be increased. The speed of...
