Abstract
The utility model relates to an improvement of a propelling device of a ship or an aircraft. The center of a round umbrella surface is fixed at the middle part of a drawbar; the bundling end of a pull rope at the edge of the umbrella surface is fixed at one end of the drawbar. The utility model has the advantage of simple structure; nearly all the driving force is used for doing work, so the propelling efficiency is high; noise is not produced in the process of propulsion; the speed limit of the utility model is higher than that of a screw propeller.
Description
The utility model relates to the improvement to a kind of boats and ships or aircraft propelling unit.
At present boats and ships or aircraft are mainly by the propeller of rotating, jet, water spray or electromagnetic type advance backward.But propeller propelling unit propulsion coefficient is low, and noise is big, and fltting speed reaches capacity, is difficult to improve again; Jet, hydraulic efficiency jet propulsion system complex structure are made difficulty; The electromagnetic propeller technology is complicated more, and the cost height does not enter the practical stage as yet.
The purpose of this utility model is to provide a kind of umbrella formula linear reciprocation propelling unit.Simple in structure, the propulsion coefficient height, noise is low.
The utility model is to realize so in conjunction with the accompanying drawings.The center fixation of circular umbrella cover 2 is at the middle part of draw bar 1, and the boundling end of umbrella cover edge stay cord 3 is fixed on an end of draw bar.
Engine is connected with living again with the other end of this propelling unit draw bar, and when draw bar during to the end motion of umbrella rope boundling, umbrella cover becomes open configuration under water or air effect, promoting boats and ships or aircraft travels forward, when the draw bar counter motion, umbrella cover draws at once, not work done of pusher.Just can be used as the propelling unit of boats and ships or aircraft and so forth.
This propelling unit has simple in structure; Driving force almost all is used for work done, propulsion coefficient height; In the progradation, do not produce noise; Velocity limit is higher than the propeller propelling unit.
Description of drawings:
Fig. 1 umbrella formula linear reciprocation propeller structure scheme drawing
Fig. 2 umbrella formula linear reciprocation propelling unit running condition scheme drawing
Embodiment: structure as shown in Figure 1 is an example with long 120mm model ship, and its umbrella formula linear reciprocation propelling unit main technical details design is as follows:
Umbrella cover adopts nylon cloth to make umbrella cover diameter 50mm
Stay cord adopts diameter 0.5mm nylon rope to make
Draw bar adopts diameter 2mm steel wire to make.
Select for use the 10W DC micromotor to be used as power.
With this propelling unit by the stern rear portion that installs to ship model, 1.2 times of the speed of its ship model model speed that to be equal-wattage promote with propeller.Noise is little.
Claims (1)
1, a kind of umbrella formula linear reciprocation propelling unit, the center fixation that it is characterized in that circular umbrella cover 2 is at the middle part of draw bar 1, and the boundling end of umbrella cover edge stay cord 3 is fixed on an end of draw bar.
