Abstract
The utility model relates to a propeller of an airplane, particularly to a novel foldable and telescopic propeller. The propeller comprises a rotating shaft and blades mounted on the rotating shaft, and is characterized in that a sliding chute is formed at the end part of a main blade, an auxiliary sliding chute is formed at the root of a telescopic blade which is embedded in the sliding chute at the end part of the main blade, and the main blade is embedded in the auxiliary sliding chute of the telescopic blade and is in hinge connection with the rotating shaft. By mounting the telescopic blade on the main blade, the utility model can realize rotation diameter variety of the blades, thereby effectively changing the pushing force of the airplane. Therefore, the utility model is particularly suitable for being used in aircrafts of automobiles, and has the characteristic of simple structure.
Description
Technical field
The utility model relates to the screw propeller on the aircraft, particularly a kind of collapsible, flexible new type propeller.
Background technology
Screw propeller on the aircraft is to be fixed on the S. A. of driving engine at present, can't change the length of its blade, in the process of flight, the thrust of aircraft has only by the rotating speed that changes driving engine and realizes, the length of screw propeller after obsolete situation is now folding is very long simultaneously, give and preserve inconvenience, particularly on the distortion automobile, just can't use.
Summary of the invention
The purpose of this utility model provides a kind of collapsible and flexible new type propeller.
Scheme of the present utility model is as follows: a kind of new type propeller, comprise S. A. and the blade that is installed on the S. A., it is characterized in that being provided with chute in the end of main blade, root at flexible blade has secondary chute, flexible blade is sleeved in the chute of main blade tips, main blade is sleeved in the secondary chute of flexible blade, and main blade is connected with the S. A. hinge.
In above-mentioned chute or secondary chute, detent mechanism is arranged.
The junction of above-mentioned main blade and S. A. is equipped with detent mechanism.
The utility model is by telescopic blade being installed on main blade, can having been realized the variation of blade rotating diameter, changed the thrust of aircraft effectively, be specially adapted to use on the automobile aircraft, having had characteristic of simple structure.
Description of drawings
Fig. 1 is the scheme drawing of the utility model after folding;
Fig. 2 is the scheme drawing of the utility model after launching.
The specific embodiment
As shown in Figure 1, 2, be provided with chute 5 in the end of main blade 6, flexible blade 4 is sleeved in the chute of main blade tips, at the root of flexible blade secondary chute 3 is arranged, and main blade is sleeved in the secondary chute of flexible blade, and main blade is connected with S. A. 1 hinge.During use, along upwards upset of hinge 2, the back that puts in place lock main blade by lockout mechanism with main blade, and the detent mechanism that has in chute 5 or secondary chute 3 of opening installation is outwards pulled out the blade that stretches and got final product then.Location and lockout mechanism can adopt prior art.
