The utility model discloses a kind of rolling angle measurement device of non-axis symmetry model in wind tunnel, belong to wind-tunnel technique field.A kind of rolling angle measurement device of non-axis symmetry model in wind tunnel, it is characterised in that：Processing coordinates inner chamber (1) inside disk (2) structure of an outwardly platform (5) centered on main body, platform (5)；On disk (2) and positioned at the outside processing observation window (4) and column pin hole (3) of platform (5)；Inner chamber (1) is coordinated to be engaged and be firmly connected by the pin in column pin hole (3) therebetween with the assembling face of cylinder of model, observation window (4) is both used for mitigating the weight of platform, it is used for the position that observing and nursing coordinates pin-and-hole on section again, it is easy to pin-and-hole to align installation, platform (5) is used to provide the plane that quadrant measures roll angle.
Description
Technical field
The utility model belongs to experiment aerodynamic scope, is related to a kind of roll angle of non-axis symmetry model in wind tunnel
Measurement apparatus.
Background technology
By converting, the method for different roll angles and the lateral aerodynamic characteristics of angle of attack mechanism coupling measurement test model is
A kind of conventional wind tunnel test methods.For axisymmetric model, along the circumferential angle groove at regular intervals of model, using height gauge
The method for measuring groove measures the roll angle of test model, and the model of plane is carried for top, usual when roll angle is little
Roll angle is measured using quadrant measurement plane, and above-mentioned side can not be then used for the nonaxisymmetric model that top does not have plane
Method measures roll angle.
The content of the invention
Problem to be solved in the utility model is the roll angle for measuring non-axis symmetry model in wind tunnel, of the present utility model
Device is connected with model precision, has platform on device, with the roll angle of the indirect measurement model of the angle of quadrant measuring table.
The technical solution of the utility model is：A kind of rolling angle measurement device of non-axis symmetry model in wind tunnel, main body
Centered on an outwardly platform disc structure, platform interior processing coordinate inner chamber；Add on disk and positioned at the outside of platform
Work observation window and column pin hole；Inner chamber is coordinated to be engaged with the assembling face of cylinder of model and therebetween by column pin hole
Pin firmly connect, observation window had both been used for mitigating the weight of platform, was used for the position that observing and nursing coordinates pin-and-hole on section again,
It is easy to pin-and-hole to align installation, platform is used to provide the plane that quadrant measures roll angle.
Described platform is square platform, or hexagon platform.
Assembling face of cylinder length long 10cm of the length of platform than model.
The sectional dimension of platform is less than the sectional dimension of disk.
The utility model having the beneficial effect that compared with prior art：The utility model devises a kind of non-axis symmetry wind-tunnel
The rolling angle measurement device of test model coordinates with model to be accurately connected, and has platform on device, with the angle of quadrant measuring table
The roll angle of indirect measurement model is spent, it is convenient and reliable using the device by wind tunnel test.
Brief description of the drawings
Fig. 1 is the utility model apparatus structure schematic diagram.
Fig. 2 is the sectional view of the utility model apparatus structure.
Fig. 3 is the model mating surface structural representation coordinated with the device.
Embodiment
The utility model is described in further details below in conjunction with the drawings and specific embodiments.
A kind of rolling angle measurement device of non-axis symmetry model in wind tunnel includes coordinating inner chamber, annulus, pin-and-hole, observation window
With square platform.The apparatus structure schematic diagram is shown in Fig. 1 and Fig. 2, and the model mating surface structural representation coordinated with the device is shown in figure
3.Inner chamber 1 is coordinated to be engaged with the cooperation cylinder 7 of model, annulus 2 and model coordinate 2 pin-and-holes of design on section 6, pass through pin-and-hole
Platform and model is accurately connected, the observation window 4 of large-size is provided with annulus, both for mitigating the weight of platform, be used for again
Observing and nursing coordinates the position of pin-and-hole on section 2, is easy to pin-and-hole to align installations, annulus 2 below with platform 5, for provide as
The plane that instrument measures roll angle is limited, platform there are multiple planes, accordingly even when still there is plane to be in upper position when roll angle is very big
Put, quadrant measurement roll angle can be placed.After the roll angle of model is adjusted in place, turnbuckle 8 is tightened, passes through pad 10
Model is compressed, makes the model conical surface 9 and balance secure fit, then lays down frock, and dummy head is loaded onto, roll angle is installed
Into.
The length of platform enables the placed longitudinally measurement model of quadrant than the assembling face of cylinder long 10cm of length of model
The angle of attack.
Described platform is square platform, or hexagon platform, the sectional dimension of platform is less than the sectional dimension of disk.
A specific embodiment of the present utility model is the foregoing is only, model of the present utility model is not limited to
Enclose.Any those skilled in the art, the equivalent variations made on the premise of design of the present utility model and principle is not departed from,
Modification belongs to the scope of the utility model protection with combining.
