The centre of gyration of type heavy duty turntable 7 is overlapped, can towing aircraft 1 move up and down, 360 degree of revolutions can also be done around lifting rope 4
Movement.
The end of suspension centre and the lifting rope 4 of hangar system 3 on aircraft 1 is attached, and aircraft 2 is located at 2 thousand on wing
Jin vertex carries out with 5 top of support rod of support jacking system 8 hinged respectively, by this connection at 3, makes aircraft 1 and " two
One hangs " device forms connection.
When aircraft 1 moves up and down, the lifting of 2 support rods 5 of the lifting rope 4 and support jacking system 8 of hangar system 3
Movement mechanism synchronization lifting makes aircraft 1 be raised to test height or be down on large-scale heavy duty turntable table top.
When aircraft 1 does pitching movement, because hangar system 3 lifting rope 4 always with the centre of gyration weight of large-scale heavy duty turntable 7
It closes, when aircraft 1 does pitching movement, the spacing needs of suspension centre and fulcrum change, therefore complete the tune of pitch angle in aircraft 1
When whole, the lifting rope 4 of hangar system 3 and the parallel moving mechanism 6 of 2 support rods 5 of support jacking system 8 is needed to do cooperative motion.
When aircraft 1 completes the pitching motion posture of some angle, large-scale heavy duty turntable 7 carries out 360 ° of rotary motion,
So that the state of aircraft 1 in this case is shown completely, is tested convenient for the RCS of aircraft, in this way, complete multiple pitch angles
The test of degree can cover the entire shape of aircraft 1 comprehensively.
It should be noted that above-mentioned flow operations can carry out different degrees of combined application, for simplicity, repeating no more
The sequence of above-mentioned operating procedure can be carried out spirit according to actual needs by various combined implementations, those skilled in the art
Adjustment living, or above-mentioned steps are subjected to the operation such as flexible combination.
Fig. 7 is the target transport vehicle structural schematic diagram of one embodiment of the invention.
As shown in fig. 7, target transport vehicle 15 may include bracket 13 and micromatic setting 14.

Setting element centered on cylinder roller bearing enables turntable to do high-precision rotary around center；Devise 8 groups of edge drivings
The extremely slow movement of large-scale heavy duty turntable can be converted into high speed by support and driving unit of the wheel group as large-scale heavy duty turntable
The high-speed motion of edge driving motor avoids creeping for turntable conducive to the motion control accuracy of large-scale heavy duty turntable.Support rises
Drop system, it is characterized in that being respectively provided with 2 sets of support rods in load-bearing frame two sides, the straight line by being arranged in load frame two sides is led
Rail guidance system and gear-rack drive system make 2 sets of support rods can either self-movement, be also able to carry out and move synchronously, meet
The elevating function for docking and supporting aircraft of supporting bar top and " push rod enters position " of aircraft fulcrum；It is set in the lower end of support rod
Parallel moving mechanism is set, support rod can be made to obtain translation function, meet the functional requirement that aircraft does pitch attitude.Hangar system,
It is characterized in that using hoist engine structure, the lifting rope being fixed on reel by one end is connected with aircraft suspension centre, controls the rotation of reel
Precision implements the lifting of aircraft suspension centre.Target transport vehicle, it is characterized in that can be by itself elevating function and fine adjustment function
Aircraft is transferred on target transport vehicle under jack holding state, and is transported on large-scale heavy duty turntable.
2. aircraft is docked with " two one are hung " device, moved by the independent-lifting of 1 support rod micro- with transport vehicle
Power Regulation is able to achieve supporting bar top with " push rod enters position " of aircraft fulcrum to connection function.
3. hangar system can pull aircraft suspension centre, support 2 support rods of jacking system that can support aircraft fulcrum, this
Test height is docked and risen to set system synchronization lifting, realization with aircraft.
4. hangar system lifting rope is overlapped with large-scale heavy duty turntable center, turntable does 360 degree of revolutions and support rod is driven to make aircraft
It is rotated in test height around turntable center, realizes the RCS detection of airplane complete machine circumferential profile.
5. the co-operating of hangar system and 2 sets of support jacking system parallel moving mechanisms makes aircraft always around large-scale weight
In the case that idling platform center is constant, the pitching motion of multi-angle is carried out, realizes the RCS inspection of airplane complete machine or more shape
It surveys.
The invention has the benefit that using the test device of " two one are hung " using aircraft connecing in the fabrication process
Mouthful, the detection that aircraft entity carries out 360 ° of revolutions and the RCS under wide-angle pitch attitude under complete machine state is solved, it will not be to winged
