Detailed Description
As shown in fig. 1 to 6, a nose cone mooring structure of an airship without a rigid skeleton comprises a base 2, a bottom ring 3, a straight stringer 5 and a circular arc stringer 6.
The base 2 is provided with a plurality of straight stringers 5, and one end of each straight stringer 5 far away from the base 2 is connected with the corresponding circular arc stringers 6 through the four-way structural member 4. The circular arc stringer 6 is provided with a through groove 6-1 matched with a fixing tab 9 on the airship capsule body 8. The bottom ring 3 is arranged between the four-way structural members 4.
The base 2 is hinged with the anchoring seat 1 through the high-strength bolt 7, so that the airship is converted into rotation around the high-strength bolt 7 in the vertical direction, and vibration of the airship in the vertical direction after mooring is completed is greatly reduced. The bottom of the anchoring seat 1 is fixedly arranged on the ground.
The fixing tab 9 is sewn on the outer surface of the front end of the airship capsule body 8.
The four-way structural member 4 is connected with the outer surface of the airship capsule body 8 through a fixing tab 9.
The longitudinal direction of the four-way structural member 4 is respectively connected with a straight stringer 5 and an arc stringer 6, and the transverse direction of the four-way structural member 4 is connected with the bottom ring 3.
The arc stringer 6 is uniformly provided with 4 through grooves 6-1.
One end of the base 2 far away from the anchoring seat 1 is connected with the straight stringers 5 through a disc, and a plurality of straight stringers 5 are uniformly arranged on the disc of the base 2. The number of the straight stringers 5 is 12, and the adjacent straight stringers 5 are spaced at 30 degrees to balance the tensile load.
The assembly process of the invention is as follows:
firstly, by analyzing the section of the head of the airship capsule body 8, a section closest to the circular arc is selected, so that the stringer of the nose cone consists of two sections, one section is the circular arc stringer 6 connected with the airship capsule body 8, and the other section is the straight stringer 5 connected with the base 2 and simplifying the force transmission route. The straight stringers 5 are connected to the circular-arc stringers 6 by means of a four-way structural member 4, the connection being as shown in fig. 2.
Four through grooves 6-1 are formed in the arc-shaped stringer 6, the fixing tabs 9 penetrate through the through grooves and are connected with the airship capsule body 8, and the four fixing tabs 9 disperse and transmit tensile force generated by the arc-shaped stringer 6 to four stress points on the airship capsule body 8, so that the condition that stress is concentrated at a certain position of the airship capsule body 8 is reduced.
12 four-way structural members 4 are sleeved on the complete bottom ring 3, and the four-way structural members 4 are connected with the airship capsule body 8 through fixing tabs 9. The terminal ends of the straight stringers 5 are connected to the base 2, and the head of the entire airship capsule 8 is centred on the horizontal axis, and a set of four-way structural members 4 and stringers are arranged on the bottom ring 3 every 30 ° to balance the tensile load.
The whole structure is mainly made of aluminum alloy, the process is simple, the assembly is rapid, and the cost is low; the airship without the rigid framework has lighter weight, and the weight of the nose cone is increased less than that of the rigid framework, so that the whole airship can carry more load due to the reduction of the weight; the nose cone structure arranged on the outer surface of the capsule body can provide a shape-preserving function on one hand, and the original air tightness of the capsule body structure can not be damaged on the other hand.
The above embodiments are only illustrative of the preferred embodiments of the present invention and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art to the technical solutions of the present invention should fall within the protection scope defined by the claims of the present invention without departing from the design spirit of the present invention.
