Abstract
The utility model discloses a kind of aircraft in wing skid pad deflector, including flow guide plate body, the flow guide plate body is installed in parallel on barrier support, the longitudinal thickness D of the flow guide plate body is 126mm, interval S between the flow guide plate body is 100mm, the angle theta of the flow guide plate body and horizontal direction is 45 °, pass through the design of the assembled dimension to flow guide plate body, when engine air-flow passes through flow guide plate body, air current flow direction generates deflecting and the relatively low region of air pressure is formed at deflector rear, so as to generate suction-operated and lead to the flowing of air, air velocity of the test run aeroengine in wing test run can largely be reduced, in the case where not changing flow guide plate body height, significantly reduce skid pad and peripheral facility usable floor area.
Description
Technical field
The utility model is related to deflector technical field, specially a kind of aircraft is in wing skid pad deflector.
Background technology
Aircraft skid pad deflector is a kind of test run engine air-flow in wing test run can not only to have been made to pass through but also can change
Airflow direction, the equipment for effectively reducing air velocity, the setting of existing deflector is unreasonable, causes flow field uneven and cannot be
Deflector rear reaches required wind speed, certainly will reach required wind speed with peripheral facility distance to increase skid pad, occupy
More resource.
Utility model content
The purpose of this utility model is to provide a kind of aircrafts in wing skid pad deflector, to solve in above-mentioned background technology
The problem of proposition.
To achieve the above object, the utility model provides following technical solution：A kind of aircraft is in wing skid pad deflector, packet
Flow guide plate body is included, the flow guide plate body is installed in parallel on barrier support, and the top of the barrier support and supporting rod connect
It connects, the barrier support is fixedly connected, and the barrier support and supporting rod and ground with the bottom of the supporting rod with ground
The angle in face is 65 °.
The flow guide plate body is made of thickness of the steel plate of 8mm, and the longitudinal thickness D of the flow guide plate body is 126mm,
Interval S between the flow guide plate body is 100mm, and the angle theta of the flow guide plate body and horizontal direction is 45 °.
Compared with prior art, the beneficial effects of the utility model are：A kind of aircraft is in wing skid pad deflector, by right
The design of the assembled dimension of flow guide plate body, when engine air-flow passes through flow guide plate body, air current flow direction generates deflecting simultaneously
The relatively low region of air pressure is formed at deflector rear, it, can be very so as to generate suction-operated and lead to the flowing of air
Air velocity of the test run aeroengine in wing test run is reduced in big degree in the case where not changing flow guide plate body height, greatly
Amplitude reduces skid pad and peripheral facility usable floor area.
Description of the drawings
Fig. 1 is the scheme of installation of the flow guide plate body of the utility model；
Fig. 2 is enlarged drawing at the A of Fig. 1；
Fig. 3 is the velocity vector detail view of flow guide plate body.
In figure：1st, flow guide plate body, 2, barrier support, 3, supporting rod.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
- Fig. 3 is please referred to Fig.1, the utility model provides a kind of technical solution：A kind of aircraft is in wing skid pad deflector, packet
Flow guide plate body 1 is included, flow guide plate body 1 is installed in parallel on barrier support 2, and the top of barrier support 2 and supporting rod 3 connect,
Barrier support 2 is fixedly connected, and barrier support 2 and supporting rod 3 and the angle on ground are equal with the bottom of supporting rod 3 with ground
It it is 65 °, flow guide plate body 1 is made of thickness of the steel plate of 8mm, and the longitudinal thickness D of flow guide plate body 1 is 126mm, deflector sheet
Interval S between body 1 is 100mm, and flow guide plate body 1 and the angle theta of horizontal direction are 45 °, pass through the ruler to flow guide plate body 1
Very little optimum organization and its angle, the setting of spacing, so as to which air velocity of the test run aeroengine in wing test run be greatly lowered,
Eliminate influence of the test run aeroengine air-flow to periphery runway and building.
As shown in Figure 3, it can be seen that flow guide plate body 1 plays the role of rearrangement to speed direction, can prevent wake flow
Excessive is ejected into the height nearer apart from ground, and as can be seen that the speed of air particle on the tail Jing Guo flow guide plate body 1
Degree has larger reduction.
While there has been shown and described that the embodiment of the utility model, for the ordinary skill in the art,
It is appreciated that can these embodiments be carried out with a variety of variations in the case of the principle and spirit for not departing from the utility model, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
