Description
Technical field
The utility model relates to surperlight type helicopter field, provides a kind of straight-line silencer of tubular type surperlight type helicopter.
Background technique
Along with surperlight type helicopter is in the application study of every profession and trade, people all the more now depopulated helicopter are day by day remarkable in the effect of social production and life All aspects of.Use modern new and high technology machinery, can not only increase work efficiency and quality, reduction operating cost.
Surperlight type helicopter domestic at present is also in elementary developing stage, and silencing apparatus many employings multistage noise reduction of traditional surperlight type helicopter, its exhaust performance is poor, there is the problem causing engine power deficiency.
Summary of the invention
It is good that the purpose of this utility model is to provide a kind of soundproof effect, and air displacement is high, can the overall silencing apparatus improving engine power.
The utility model is to achieve these goals by the following technical solutions:
A kind of straight-line silencer of tubular type surperlight type helicopter, it is characterized in that, comprise air pipe (1), seam (4), noise elimination cavity, noise elimination cavity comprises shell, noise elimination air pipe (3-1,3-2) is in the enclosure set, between shell and noise elimination air pipe (1), is provided with resonant cavity (2) and honeycomb noise elimination cavity (3-3), noise elimination air pipe (3-1,3-2) is evenly equipped with through hole (3-4).
In technique scheme, described noise elimination air pipe (3-1,3-2) comprises front hush tube (3-1) and rear hush tube (3-2).
In technique scheme, resonant cavity (2) is arranged between front hush tube (3-1) and housing, and honeycomb noise elimination cavity (3-3) is arranged between rear hush tube (3-2) and housing.
In technique scheme, resonant cavity (2) comprises the resonant panel (2-1) that gap is arranged, and resonant panel (2-1) one end is vertical with the tube wall of housing, and the other end is provided with turning (2-2).
In technique scheme, described honeycomb noise elimination cavity (3-3) is Cellular Networks structure.
In technique scheme, air pipe (2) is 2.
Because the utility model adopts technique scheme, therefore possess following beneficial effect:
The utility model adopts the structure of prime resonant cavity rear class honeycomb noise elimination cavity 2 grades of noise reductions, ensure that the erasure effect of baffler, and the straight tube that noise elimination air pipe of the present utility model is integrated, which ensure that the air displacement of motor, thus compare existing silencing apparatus, power about the 15%-25% of motor can be improved.
Accompanying drawing explanation
Fig. 1 is stereogram of the present utility model.
