Technical Field

The invention relates to the field of stratospheric airship structures, in particular to a local hard stratospheric airship.

Background

The stratospheric airship has very wide military and civil values, and has great application values in aspects such as missile defense, anti-terrorism, communication, remote sensing, space observation, atmospheric measurement and the like. An airship, one type of aerostat, is an aircraft that uses a lighter-than-air gas to provide lift. The lift obtained by the airship mainly comes from lighter-than-air gas filled inside the airship, such as hydrogen, helium and the like.

Generally, from a structural point of view, conformal airships can be divided into three types: blimps, semi-rigid airships and rigid airships.

The conventional blimp is composed of a main airbag and an auxiliary airbag. The main air bag stores helium to generate buoyancy; the auxiliary air bag stores air, the pressure difference between the inside and the outside of the airship body is controlled and adjusted through the fan, and the shape of the airship is kept by the elastic rigidity of the air. The helium gas bag in the airship can shrink when meeting cold at night, and the blower is used for injecting air to generate pressure difference between the inside and the outside of the airship so as to keep the shape of the airship. In order to maintain the shape of the airship body, the soft airship needs to maintain the basic pressure difference to generate the gas elastic rigidity; if the pressure difference in the airship is too low, deformation is generated, so that the structure is easy to be unstable, the propulsion systems on the two sides of the soft airship are influenced by gravity and thrust to form a couple, deformation is easily generated on the shape of the airship capsule, and wind-resistant flight is not facilitated. Furthermore, local stress concentrations are liable to arise when loading is carried out.

The hard airship can solve the problems, but the proportion of the structural weight in the overall weight of the airship is large.

Therefore, it is highly desirable to develop a local hard type stratospheric airship, in which a hard type structure is locally added to a stressed portion of the airship bearing load, so that the stress of the airship is uniformly distributed and the stress concentration is reduced.

The above information disclosed in this background section is only for enhancement of understanding of the background of the invention and therefore it may contain information that does not constitute prior art that is already known to a person of ordinary skill in the art.

Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The drawings are merely schematic illustrations of the invention and are not necessarily drawn to scale.

Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to provide a thorough understanding of embodiments of the invention. One skilled in the relevant art will recognize, however, that the invention may be practiced without one or more of the specific details, or with other methods, components, steps, and so forth. In other instances, well-known structures, methods, implementations, or operations are not shown or described in detail to avoid obscuring aspects of the invention.

As a first embodiment of the present invention, an object of the present invention is to disclose a partially hard stratospheric airship including, as shown in fig. 1 and 2: a blimp, a plurality of strengthening rings 3 and a plurality of strengthening rings 1.

The blimp comprises a vector lateral thrust system 2, an advancing lateral thrust system 4, a lateral thrust bracket 6, a tail thrust bracket 5, a vector tail thrust system 8, an outer capsule 7, a nose cone 9 and a tail cone 10. The side-push bracket 6 is of a rod-shaped or truss structure, is horizontally arranged and is vertical to the longitudinal axis of the airship, and is used for connecting the hull of the blimp and a side-push system (comprising a vector side-push system 2 and an advancing side-push system 4). The vector lateral thrust system 2 is fixed on two sides of the blimp through the lateral thrust support 6, and the vector lateral thrust system 2 is arranged at the front part of the blimp, which is far away from the center of mass of the blimp. The vector lateral thrust system 2 can adjust the pitching attitude of the airship within a rotation range of +/-theta by taking the lateral thrust support 6 as an axis, wherein theta is 90 degrees. When the vector lateral thrust system 2 does not need to adjust the pitching attitude of the airship, the rotating angle of the vector lateral thrust system 2 is 0 degree, and the vector lateral thrust system 2 provides forward flying power for the airship. The advancing side-push systems 4 are fixed on two sides of the blimp through side-push brackets 6 to provide forward flight power for the blimp, and multiple groups of advancing side-push systems 4 (one group is two advancing side-push systems 4 symmetrically arranged on two sides of the blimp) can be arranged in practical application. In fig. 1 and 2, the vector lateral thrust system 2 is located at the front of the airship and the forward lateral thrust system 4 is located at the rear of the airship, but in practical application, the vector lateral thrust system 2 may be arranged at the rear of the airship and the forward lateral thrust system 4 may be arranged at the front of the airship. The tail cone 10 is arranged at the tail part of the blimp and corresponds to the nose cone 9. The tail cone 10 is fixedly connected with the tail push bracket 5. The tail pushing support 5 is of a rod-shaped structure or a truss structure and is parallel to the longitudinal axis of the blimp. The vector tail pushing system 8 is fixed on a tail cone 10 through a tail pushing support 5. The vector tail-pushing system 8 can adjust the yaw direction of the airship by taking a vertical line of the tail-pushing support 5 as an axis within a rotation range of +/-beta, wherein the beta is 90 degrees. The nose cone 9 is arranged on the outer bladder 7 at the foremost part of the blimp.

A plurality of reinforcing rings 3 are fixed in parallel to the outer bladder 7, each reinforcing ring 3 having a centre located on the longitudinal axis of the blimp. In fig. 1 and 2, 2 reinforcing rings 3 are arranged, each reinforcing ring 3 is fixedly connected with a pair of side-push brackets 6, each pair of side-push brackets 6 comprises two side-push brackets 6, and the two side-push brackets 6 are respectively arranged on two sides of the airship. In practical application, several reinforcing rings 3 can be arranged near the side-push bracket 6 and fixedly connected with the side-push bracket 6, or the reinforcing rings 3 which are not connected with the side-push bracket 6 can be arranged at other places to keep the boat shape. A plurality of side-push brackets 6 can be fixedly connected to each reinforcing ring, so that the airship is stressed more uniformly.

The reinforcing ring 1 is arranged on the outer bag body 7 and is positioned at the joint of the reinforcing ring 3 and the side-push bracket 6. A plurality of reinforcing rings 3 can be connected to one reinforcing ring 1, and a plurality of reinforcing rings 1 can be arranged at the joint of the reinforcing rings 3 and the side pushing bracket 6, so that the rigidity and the stability of the joint can be improved, but the weight can be increased.

The outer bag body of the soft airship is provided with a plurality of reinforcing rings 3 to form a local frame, so that the shape of the airship can be kept under the condition of lower air pressure difference, and the airship can resist wind and fly at night; because the structure of the reinforcing ring 3 is adopted, the complex hard frame structure of the hard airship is abandoned, the weight is saved, and the saved weight can be used for reinforcing the weight of the capsule material of the strength of the outer capsule. Meanwhile, the reinforcing ring 3 is connected with the side-push bracket 6, the reinforcing ring 1 is arranged at the joint, and the local rigidity of the joint of the outer bag body 7 and the side-push bracket 6 is increased, so that the damage effect of the bending moment generated by the bracket of the side-push system on the shape of the airship under the condition of lower pressure difference between the inside and the outside of the airship of the stratosphere airship is reduced.
