Abstract
The invention discloses a special plastic shovel blade for wind tunnel tests, which is composed of a blade (1) and a handle (2). The special plastic shovel blade is characterized in that the blade (1) and the handle (2) are integrally prepared into a whole through injection moulding by using plastics; the thickness of the blade (1) closer to the handle (2) is gradually increased; the top of the handle (2) is provided with an index finger slot (3); one side wall of the handle (2) is provided with a thumb slot (4); the bottom of the handle (2) is provided with a groove (5); and the handle (2) is in the shape of a mouse. Compared with the traditional iron shovel blade, the special plastic shovel blade for wind tunnel tests, disclosed by the invention, can prevent the blowing test data of a model from being affected because the appearance of the model is damaged, and can effectively ensure the integrity and high similarity of the appearance of the model.
Description
One, technical field
The invention belongs in the wind tunnel test model surface and repair the type specific purpose tool, be specially wind tunnel test special plastic perching knife.
Two, background technology
In the wind tunnel test, there is more screw hole on model (aviation or aerospacecraft, automobile etc.) surface, must fill up this hole and carry out curved surface and repair type with soft material (generally using plasticine), and model repaiied that type is general to carry out operation with common on the market irony perching knife (the iron plate perching knife with wood handle of using such as the Puttying of building decoration field) in the past, did not have special-purpose model in wind tunnel to repair the type instrument.The easy damage model of irony perching knife and affect model blowing test figure.Especially concerning the aircraft of supercritical airfoil, very responsive along the air-flow effects on surface roughness that its upper surface of the airfoil leading edge flows through, therefore carry out to reduce when the model screw hole is repaiied type the destructiveness of effects on surface at leading edge of a wing place, otherwise may affect lift efficiency and the suffered aerodynamic force of whole aircraft of wing, thereby affect the precision of aircraft wind tunnel test data.
Three, summary of the invention
The objective of the invention is to design a kind of wind tunnel test special plastic perching knife that had not only made things convenient for use but also be not easy damage model.
The present invention is achieved in that a kind of wind tunnel test special plastic perching knife, is made of blade and handle, it is characterized in that: blade and handle adopt the plastic monoblock injection mo(u)lding to be integrated; The closer to handle part, the thickness of blade progressively increases; The top of handle is provided with the forefinger groove; One sidewall of handle is provided with thumb grooves.
Further scheme is: be provided with groove at the bottom of the section of handle.
Further scheme is: handle be shaped as mouse-like.
Blade of the present invention bottom surface should smooth planar, is beneficial to the type of repairing of model surface plasticine; Groove in the middle of the handle bottom not only can play the loss of weight effect but also can deposit plasticine, is convenient to the staff and uses.This perching knife material is generally the high rigidity plastics, and the perching knife head is the requirement of strength of blade position hardness should satisfy plasticine and repair type the time.
Design philosophy of the present invention is from the ergonomics angle, and based on the consideration of man-machine interface, its general layout design thought source is in mouse, and its characteristics are as follows:
This perching knife quality is less, convenient operation;
This plastics perching knife is that model surface is repaiied the type specific purpose tool in aviation or aerospacecraft, the automobile wind tunnel test, and the main and model surface of this perching knife is repaiied shaped material (plasticine) and is used in conjunction with.
This special plastic perching knife is compared with traditional irony perching knife, and can avoid affects model blowing test figure because of the damage of model external form; Can effectively guarantee model external form integrality and high similarity.In addition, the invention of this perching knife has been filled up in the wind tunnel test model and has been repaiied this blank of type special plastic instrument.

Five, embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described in detail, the present embodiment provided detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment take technical solution of the present invention as prerequisite.
Such as Fig. 1, Fig. 2, Fig. 3 and Fig. 4, Fig. 5 and shown in Figure 6, a kind of wind tunnel test special plastic perching knife is made of blade 1 and handle 2, it is characterized in that: blade 1 adopts the plastic monoblock injection mo(u)lding to be integrated with handle 2; The closer to handle 2 positions, the thickness of blade 1 progressively increases; The top of handle 2 is provided with forefinger groove 3; One sidewall of handle 2 is provided with thumb grooves 4.Be provided with groove 5 at the bottom of the section of handle 2.Handle 2 be shaped as mouse-like.
This perching knife is generally used the whole integral molded plastic moulding of highstrenghtpiston.
The use-pattern of this perching knife is fairly simple, and hand-held is the same with the mode of using computer mouse, and during work, hold with a firm grip forefinger and thumb get final product.
Determining of the forefinger position of this perching knife upper surface and the thumb position of side can be through repetition test location repeatedly.Process can be as follows:
Make the perching knife (material is softer) of same ratio and profile of plasticine, different staff is with holding this perching knife, in the middle of the force process, forefinger and thumb are as mainly having stayed the darker marking with the force at mould, determine the concrete scope of forefinger and thumb according to this marking, use so that point staff different in size.This perching knife also can carry out the size fine setting in the middle of process, to improve its cost performance.
Claims (3)
1. a wind tunnel test special plastic perching knife is made of blade (1) and handle (2), it is characterized in that: blade (1) adopts the plastic monoblock injection mo(u)lding to be integrated with handle (2); The closer to handle (2) position, the thickness of blade (1) progressively increases; The top of handle (2) is provided with forefinger groove (3); One sidewall of handle (2) is provided with thumb grooves (4).
