Description
Technical Field
The invention relates to the technical field of rapid course alignment guarantee of carrier-based aircrafts, in particular to a lower support block of a compatible mobile course measuring device.
Background
The shipborne helicopters on the amphibious attacking ship mainly comprise straight-18 and straight-9D helicopters and other two types of helicopters, and the mechanical interfaces of the aircraft hangers for carrying out course alignment on the two types of helicopters are not consistent: the straight-18 shipborne helicopter in the upward navigation direction is aligned to the aircraft hanger by adopting a double-wedge-shaped lower support block structure, while the straight-9D shipborne helicopter in the upward navigation direction is aligned to the aircraft hanger by adopting a single-wedge-shaped lower support block structure, so that the same type of mobile course measuring device cannot be simultaneously and compatibly installed on the two shipborne helicopters with different lower support block structures.
Aiming at the problem that the interfaces of the upper support block and the lower support block of the upper aviation direction alignment flight frame hanging rack of the two types of ship-based helicopters are not consistent, the mobile course measuring device developed by the inventor needs to be attached with the following two different support block structures (as shown in figures 1 and 2), and thus the two types of mobile course measuring devices with different lower support block structures are formed. In order to guarantee the course alignment of two different shipboard aircrafts, namely straight-18 and straight-9D, by adopting a single type of mobile course measuring device, a composite lower support block structure which is compatible with the two types of aircraft course alignment hangers needs to be developed.

The integrated composite lower supporting block structure is designed by combining two different lower supporting block structures butted on an original straight-18 airplane and a straight-9D airplane. The composite lower supporting block structure is a composite superposition improvement design on the original double-wedge lower supporting block structure (as shown in figure 1), and a single-wedge surface (as shown in figure 3) is cut on the double-wedge lower supporting block structure leftwards according to a sketch on the right side of figure 3, so that the lower supporting block structure can not only keep a part of the double-wedge surface to be aligned with the course of a straight-18 ship-borne helicopter, but also can adopt a newly cut single-wedge surface to be aligned with the course of a straight-9D ship-borne helicopter.

Detailed Description
The following detailed description of the embodiments of the present invention is provided in conjunction with the accompanying drawings, which are intended to be illustrative, not limiting, and not limiting.
A lower support block of a compatible movable course measuring device comprises a lower support block structure main body, three mounting holes (namely a middle mounting hole 5, a left end mounting hole 1 and a right end mounting hole 7) are uniformly distributed on the lower support block structure main body, and a groove surface 4 is formed on the outer side of the middle mounting hole. An inclined mounting surface 3 is obliquely cut in the middle of the upper surface of the lower supporting block structure main body, and the inclined mounting surface cuts through the whole middle mounting hole, cuts through part of the left and right mounting holes and symmetrically cuts through the left and right mounting holes.
The inclined mounting surface is consistent with the mounting inclined surface on the original single-wedge type supporting block structure and is used for ensuring that the movable course measuring device is in butt joint with a single-wedge type lower supporting block on a straight-9D type ship-borne helicopter; and simultaneously, a double-wedge-shaped triangular mounting surface 2 and a double-wedge-shaped triangular mounting surface 6 are respectively reserved at the left end and the right end of the upper surface of the lower supporting block structure main body, and the two double-wedge-shaped mounting surfaces are used for butt joint with a double-wedge-shaped lower supporting block on a straight-18 ship-borne helicopter.
In order to verify the influence of the newly designed composite lower supporting block structure on the course alignment precision, the course alignment precision test is carried out by comparing the composite lower supporting block structure with a single-wedge lower supporting block structure and a double-wedge lower supporting block structure, and the test results are as follows:
TABLE 1 course alignment test results of single wedge lower shoe on straight-9D mechanical interface
TABLE 2 course alignment test results of composite lower carrier on straight-9D mechanical interface
The mean value processing of the course alignment measurement results of the composite lower support block on the straight-9D mechanical interface is as follows:
1) heading alignment angle α 299 ° 53' 23.2 ″
2) Fore-aft horizontal alignment angle β 1 ═ 45', 41.8 ″
3) Left-right horizontal alignment angle β 2 ═ 2' 37.4 ″
The difference between the heading alignment measurement results of the composite lower support block and the single-wedge lower support block on the straight-9D mechanical interface is as follows:
1) heading alignment angle deviation delta alpha is 2.7 ″)
2) The deviation delta beta 1 of the horizontal alignment angle of the fore-aft direction is 8.2 ″)
3) The left-right horizontal alignment angle deviation Δ β 2 is 12.6 ".
TABLE 3 course alignment test results of double wedge lower carrier on straight-18 mechanical interface
TABLE 4 course alignment test results of composite lower carrier on straight-18 mechanical interface
The mean value processing of the course alignment measurement results of the composite lower support block on the straight-18 mechanical interface is as follows:
4) heading alignment angle α 299 ° 38' 19.8 ″
5) Fore-aft horizontal alignment angle β 1 ═ 59', 40.3 ″
6) Left-right horizontal alignment angle β 2 ═ 3' 6.7 ″
The difference between the heading alignment measurement results of the composite type lower supporting block and the double-wedge type lower supporting block on the straight-18 mechanical interface is as follows:
4) heading alignment angle deviation delta alpha is 3.8 ″)
5) The deviation delta beta 1 ═ 1' 10.3 ″, of the horizontal alignment angle of the fore-aft direction
6) The left-right horizontal alignment angle deviation Δ β 2 is 15.3 ".
By comparing the newly designed composite lower supporting block structure with the original single-wedge and double-wedge lower supporting block structures for course alignment, it can be seen that:
a) the composite lower supporting block replaces the original two lower supporting block structures, so that the deviation on the course alignment angle is small, the deviation is basically controlled within the range of 5 ″, and the course alignment requirement can be met;
b) in the aspect of horizontal alignment angle, the deviation of the horizontal alignment angle generated when the single-wedge-shaped lower support block is replaced is small, and the fore-aft direction and the left-right direction are basically in the range of 15'; the horizontal alignment angle generated when the double-wedge type lower support block is replaced has larger deviation, wherein the deviation of the fore-aft horizontal alignment angle is 1 ' 10.3 ' and the deviation of the left-right horizontal alignment angle is 15.3 '.
It is understood that single and double wedge under-tray structures are inherently prone to variations in horizontal alignment angle upon repeated alignment, wherein single wedge horizontal alignment angle variations are small, substantially controlled to within 15 ", while double wedge under-tray structures are prone to large horizontal alignment angle variations, up to 3' at most. Therefore, the composite bottom bracket structure can be considered to be horizontally equivalent to the original single-wedge bottom bracket and double-wedge bottom bracket structures in terms of horizontal alignment angle. The horizontal alignment deviation can be compensated by software, so that the overall course alignment precision of the mobile course measuring device is not influenced.
The comparison of the above composite lower supporting block structure with the course alignment test of the original single-wedge lower supporting block and double-wedge lower supporting block structures can confirm that the newly designed composite lower supporting block structure can be compatible with the course alignment design requirements of straight-9D, straight-18 and other two types of ship-borne helicopters, and can be popularized and applied to aircraft carriers and drive and protect ships to be compatible with different ship-borne aircrafts with single-wedge and double-wedge lower supporting block structures for course alignment.
The invention solves the problem that the upper and lower support block structures of the aircraft hanger are incompatible when the mobile course measuring device aligns the courses of the straight-18 and straight-9D shipborne helicopters on the amphibious attacking ship, the designed composite lower support block structure can be compatible with the double-wedge type and single-wedge type lower support block structures on the two aircraft hangers at the same time, the problem that the traditional mobile course measuring device is incompatible on the single-wedge type and double-wedge type lower support block flying rack is solved, and meanwhile, the composite lower support block structure can be popularized to the shipborne aircrafts, such as an aircraft carrier, a driving and protecting ship and the like, which respectively have the single-wedge type and double-wedge type lower support block structures for course aligning application, and has important practical significance.
