Detailed description of the invention
Examples of the present invention will be described by way of reference to the accompanying drawings, in which:
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the structural schematic diagram of the position driving mechanism in the present invention；
Wherein: 1 is injection type nacelle, and 2 be ventilation strut, and 3 be ventilation block, and 4 be high-pressure air source interface, and 5 be position driving
Mechanism, 6 be connection square chest；5.1 be outline border lead screw, and 5.2 be inside casing, and 5.3 be ventilation block mounting surface, and 5.4 be inside casing lead screw, 5.5
It is outline border, 5.6 be inside casing lead screw driving nut, and 5.7 be inside casing and outline border lead screw attachment base, and 5.8 be outline border lead screw driving rocker arm.
Specific embodiment
All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.
As shown in Fig. 1, entire Mobile support device includes two parts, and a part is ventilation strut and injection type nacelle,
Another part is position driving mechanism.Since it is considered that the present apparatus is for the support in half model test to injection type nacelle
Effect, and injection type nacelle is to need to be provided in the corresponding position of model wing, and injection type nacelle cannot be carried out with wing
Contact, therefore the structure of the ventilation strut in the present invention is used for the support of injection type nacelle.
Strut ventilate using the tubular structure of rigidity, in order to avoid being contacted with half model, therefore uses curved shape
Shape allows ventilation strut to get around half model；And the strut of tubulose is to need to be connected to inside injection type nacelle, it is convenient logical
It crosses external to conveying high-pressure gas source in injection type nacelle.The other end of ventilation strut is fixed on Vent Module, mould of ventilating
Connector is provided on block to be connected to high-pressure air source.
As shown in Fig. 2, because injection type nacelle is to need to carry out position relative to half model wing to adjust to close in the present invention
System, and the adjusting of position is divided into several directions, all around and the tune of vertical direction relative to the fixed position of wing
Section.
The adjusting of vertical direction is realized by a connection square chest, thus it is possible to vary the height of square chest is connected, thus can be light
The change injection type nacelle of pine is relative to the position change in the vertical direction of wing；Or replacement support rod, increase support rod
The length of vertical component is to realize the change to whole height.
And position all around is adjusted, and is mainly adjusted by two lead screws in the driving mechanism of position.Entire position
Setting driving mechanism includes an outline border, and an outline border lead screw is provided in outline border, and outline border lead screw is engaged by screw thread with inside casing,
By rotating outline border screw rod inside casing is moved along the direction of outline border screw rod.And inside casing lead screw is provided in inside casing, inside casing
V-way is arranged in screw rod two sides, is engaged with a sliding block by screw thread on inside casing lead screw, is driven and is slided by rotation inside casing lead screw
Block is moved on V-way along inside casing screw rod.And Vent Module is just mounted on sliding block and V-way.Therefore pass through
Rotation outline border lead screw and inside casing lead screw can adjust the positional relationship all around of injection type nacelle.
In actual tests, the present apparatus is to need to be installed under wind-tunnel in the melt pit of hole wall, only ventilation strut and injection
Formula nacelle is extend into wind-tunnel, is controlled the present apparatus by control system and is tested accordingly.
The invention is not limited to specific embodiments above-mentioned.The present invention, which expands to, any in the present specification to be disclosed
