Abstract
The invention provides a turbo propeller applicable to driving a rail locomotive. A motor drives a turbo compressor to compress the air entering the turbo compressor; the compressed air is ejected by an ejector tube to generate recoil force; the recoil force drives the rail locomotive to move; the air in front of the rail locomotive moving can be sucked and compressed from the rear so as to increase the rear pressure of the rail locomotive, the air pressure of the front of the rail locomotive drops, and a severalfold pressure difference is generated to drive the rail locomotive to move.
Description
Technical field
The present invention relates to a kind of turbine propulsion device, be applicable to the driving dynamics of rail locomotive.
Background technique
The locomotive travelled in vacuum pipe, owing to not having the resistance of air, the speed of locomotive may bring up to thousands of kilometer per hour when equal energy consumption, but build the suitable complexity of this huge vacuum pipe, costly.
Summary of the invention
The invention provides a kind of turbine propulsion device, it utilizes motoring turbocompressor, compresses the air entered in gas compressor, and eject generation recoil force through injection pipe; As the driving dynamics of rail locomotive, advancing for locomotive forward air can suck and from rear portion extrusion, the pressure at locomotive rear portion be improved by it, and the air pressure of locomotive front portion declines, and the pressure difference drive track locomotive therefore producing several times advances.
The present invention realizes with following technological scheme: a kind of turbine propulsion device, comprises housing, multistage stator blade grid that segmentation is fixed on inner walls, is alternately distributed at the multistage turbine fan between two between stator blade grid, the half-cone hollow sleeve of fixing multistage turbofan, the motor be sleeved in half-cone hollow sleeve, supports the antero posterior axis board of half-cone hollow sleeve, the intake grill air guiding grid of fixed electrical machinery two output shaft and exhaust port air guiding grid, the injection pipe that is connected with exhaust port air guiding grid;
It is characterized in that: described housing be taper it be formed by two shell combination of double; The leaf grating face length direction of described multistage stator blade grid is curved surface, the leaf grating that length is identical is divided into two groups and is fixed on two to half-open housing inner circumferential by certain drift angle decile by housing air inlet, and the length of multistage stator blade grid is successively decreased to rear class successively by prime; The flabellum of described multistage turbine fan is distributed in half-cone hollow sleeve outer circumferential face successively by the segmentation of length same hierarchical and is certain drift angle; Described motor is made up of external rotor, inner stator, output shaft, the external rotor of motor is fixed on half-cone hollow sleeve inwall, the antero posterior axis board that the output shaft at motor inner stator two is installed by half-cone hollow sleeve two supports, fitted bearing between antero posterior axis board and motor output shaft, the assemblying body of motor and turbofan is fixed on intake grill air guiding grid and exhaust port air guiding grid between the two by output shaft, and can freely rotate; According to above-described: be provided with two of stator blade grid and half-open housing merged to be connected with exhaust port air guiding grid by intake grill air guiding grid be overall structure, utilize the multistage turbofan pressure of motoring to compress the air entered in gas compressor, compression ratio is high, recoil force is large.
Good effect of the present invention
1., except as except the driving dynamics of rail locomotive, also can be used for other transit equipment.
2. structure is simple, and can form higher compression ratio, recoil force is large.
