Abstract
A kind of forward type pond towing trial device, it includes acting trailer system (1), pedestal (2), girder (3), locking adjusting apparatus (4), track (5), jigger (6), deep bar (7), trousers (8), electric pushrod (9), guider and model (11), model (11) is positioned at below the front end of acting trailer system (1), pedestal (2) is arranged on acting trailer system (1), girder (3) is steel frame construction, girder (3) end is arranged on pedestal (2) by flange, and girder (3) front end is provided with trousers (8)；This device substantially reduces the interference to model surrounding flow field of trailer and assay device, model test district air velocity and towed speed error are less than 2%, more former test method error reduces 10%, aircraft hydrodynamic(al) performance prediction is more accurate, device quality is little, intensity is big for this, simple to operate, applied widely.
Description
Technical field
The invention belongs to water surface flying device test field, be specifically related to a kind of forward type pond towing trial device.
Background technology
At present, the design of water surface flying device wants a large amount of with reference to the hydrodynamic performance test in towing basin, existing assay device is to be placed in model bottom trailer to carry out towing trial, the region of a relative closure is defined bottom the pool wall of towing basin both sides and trailer, and model test speed is higher, air-flow becomes the most disorderly when entering pilot region, causes the situation that air velocity is inconsistent with towed speed, causes model attitude to occur in that bigger deviation with design estimation.
Summary of the invention
The purpose of the present invention is aiming at present, the design of water surface flying device wants a large amount of with reference to the hydrodynamic performance test in towing basin, existing assay device is to be placed in model bottom trailer to carry out towing trial, the region of a relative closure is defined bottom the pool wall of towing basin both sides and trailer, and model test speed is higher, air-flow becomes the most disorderly when entering pilot region, cause the situation that air velocity is inconsistent with towed speed, cause model attitude to occur in that bigger deviation with design estimation, and a kind of forward type pond towing trial device is provided.
nullThe present invention includes acting trailer system、Pedestal、Girder、Locking adjusting apparatus、Track、Jigger、Deep bar、Trousers、Electric pushrod、Guider and model，Model is positioned at below the front end of acting trailer system，Pedestal is arranged on acting trailer system，Girder is steel frame construction，Girder end is arranged on pedestal by flange，Girder front end is provided with trousers，Locking adjusting apparatus one end is arranged on acting trailer system，The other end is by the front end of carbon fiber pipe locking girder，Track installation is in the steelframe of girder front end，Jigger is installed in orbit by one group of pulley，Deep bar is from top to bottom through jigger，And the bottom of deep bar is connected with model by connecting rod，Electric pushrod is arranged on bottom jigger，The push rod of electric pushrod is connected with deep bar bottom by rope，Guider is made up of forked gag lever post and guide post，The top of guide post is arranged on girder，One end radial type of forked gag lever post is arranged on the bottom of guide post，The other end of forked gag lever post is inserted on the navigation post of model afterbody.
The method have the advantages that: this device has had in vertical traction position and is greatly improved, model surrounding forms relatively spacious pilot region, substantially reduce the interference to model surrounding flow field of trailer and assay device, model test district air velocity and towed speed error are less than 2%, more former test method error reduces 10%, and aircraft hydrodynamic(al) performance prediction is more accurate, and device quality is little, intensity is big for this, simple to operate, applied widely.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
nullAs shown in Figure 1，The present invention includes acting trailer system 1、Pedestal 2、Girder 3、Locking adjusting apparatus 4、Track 5、Jigger 6、Deep bar 7、Trousers 8、Electric pushrod 9、Guider and model 11，Model 11 is positioned at below the front end of acting trailer system 1，Pedestal 2 is arranged on acting trailer system 1，Girder 3 is steel frame construction，Girder 3 end is installed on the base 2 by flange，Girder 3 front end is provided with trousers 8，Locking adjusting apparatus 4 one end is arranged on acting trailer system 1，The other end is by the front end of carbon fiber pipe locking girder 3，Track 5 is arranged in the steelframe of girder 3 front end，Jigger 6 is installed on the rail 5 by one group of pulley，Deep bar 7 is from top to bottom through jigger 6，And the bottom of deep bar 7 is connected with model 11 by connecting rod，Electric pushrod 9 is arranged on bottom jigger 6，The push rod of electric pushrod 9 is connected with deep bar 7 bottom by rope，Guider is made up of forked gag lever post 10 and guide post 12，The top of guide post 12 is arranged on girder 3，One end radial type of forked gag lever post 10 is arranged on the bottom of guide post 12，The other end of forked gag lever post 10 is inserted on the navigation post of model 11 afterbody.
nullOperation principle: model 11 is positioned at below acting trailer system 1 front end，It is connected on girder 3 by deep bar 7 and guider 10，Make model 11 can advance along the direction of advance of acting trailer system 1，The disorderly air-flow simultaneously avoiding acting trailer system 1 and the relative closure region of pool wall formation and produce carrys out interference model 11，Locking adjusting apparatus 4 regulates levelness and the symmetry of girder 3，Make the jigger 6 can be the most freely-movable，Deep bar 7 can be vertically freely-movable on jigger 6，Ensure the degree of freedom that model 11 fluctuates in traveling along with wave，Trousers 8 is arranged on girder 3 front end，Reduce the air drag of experimental provision in experiment，Thus improve the experimental precision of model 11，Electric pushrod 9 connects the bottom of deep bar 7 by rope，Play the effect of folding and unfolding model 11，It is the most immovable that forked gag lever post 10 is inserted in limited model 11 on the navigation post of model 11 afterbody，Ensure that model 11 along acting trailer system 1 direction of advance advance time steady.
