Description

Technical Field

[0001] The invention relates to the field of stratospheric airship structures, in particular to a partially rigid stratospheric airship. Background Art

[0002] Stratospheric airships have a wide range of military and civilian applications, such as missile defense, communications, remote sensing, space observation, and atmospheric measurement. Airships are a type of aerostat, which is an aircraft that uses lighter-than-air gases to provide lift. The lift obtained by airships mainly comes from the lighter-than-air gases inside them, such as hydrogen and helium.

[0003] Generally speaking, conformal airships can be divided into three types from a structural point of view: soft airships, semi-rigid airships and rigid airships.

[0004] Conventional airships are composed of main and auxiliary airbags. The main airbag stores helium to generate buoyancy; the auxiliary airbag stores air, and adjusts the pressure difference between the inside and outside of the hull through fan control, using its air elastic stiffness to maintain the shape of the airship. At night, the temperature inside the hull drops sharply, and the helium airbag will shrink when it is cold. At this time, air is injected through the fan to generate a pressure difference between the inside and outside of the hull to keep the shape of the airship. In order to maintain the shape of the hull, the airship must maintain a basic pressure difference to generate gas elastic stiffness; if the pressure difference inside the hull is too low, deformation will occur, which can easily cause structural instability. The propulsion systems on both sides of the airship are affected by gravity and thrust to form a force couple, which can easily cause deformation of the airship hull shape, which is not conducive to wind-resistant flight. In addition, local stress concentration is easily caused when loading loads.

[0005] Rigid airships can solve the above problems, but the structural weight accounts for a large proportion of the overall weight of the airship.

[0006] Therefore, it is urgent to develop a partially rigid stratospheric airship, in which a rigid structure is locally added to the load-bearing part of the airship to evenly distribute the force on the airship and reduce stress concentration.

In the following description, many specific details are provided to provide a full understanding of the embodiments of the present invention. However, those skilled in the art will appreciate that the technical solution of the present invention may be practiced while omitting one or more of the specific details, or other methods, components, steps, etc. may be adopted. In other cases, known structures, methods, implementations or operations are not shown or described in detail to avoid obscuring various aspects of the present invention.

[0063] As a first embodiment of the present invention, the present invention aims to disclose a partially rigid stratospheric airship, such as Figure 1 and Figure 2 As shown, it includes: a soft airship, multiple reinforcement rings 3, multiple reinforcement rings 1, multiple first bow ties 14, multiple binding ropes 15, multiple second bow ties 17, multiple side thrust bracket tensioning ropes 11, multiple reinforcement ring support rods 13 and multiple side thrust bracket support rods 12.

[0064] The soft airship includes a vector thrust system 2, a forward thrust system 4, a thrust bracket 6, a tail thrust bracket 5, a vector tail thrust system 8, an outer sac 7, a nose cone 9 and a tail cone 10. The thrust bracket 6 is a rod-shaped or truss structure, and can be a hollow tubular structure or a solid structure. The thrust bracket 6 is made of carbon fiber, steel, aluminum alloy and / or titanium alloy, preferably carbon fiber and / or aviation aluminum alloy. Carbon fiber and aviation aluminum alloy are light in weight and high in strength. The thrust bracket 6 is arranged horizontally or obliquely and is perpendicular to the longitudinal axis of the airship, and is used to connect the soft airship body and the thrust system (including the vector thrust system 2 and the forward thrust system 4). Figure 8 As shown, each side thrust bracket 6 is arranged on the outside of the outer sac 7, and each side thrust bracket 6 corresponds to a plurality of second bow ties 17 and a plurality of side thrust bracket tension ropes 11, and each second bow ties 17 corresponds to a side thrust bracket tension rope 11. The second bow ties 17 are fixed to the outer surface of the outer sac 7 near the side thrust bracket 6. One end of the side thrust bracket tension rope 11 is tied to the second bow ties 17, and the other end is tied to the side thrust bracket 6. The vector side thrust system 2 is fixed to both sides of the soft airship through the side thrust bracket 6, and the vector side thrust system 2 is arranged at the front of the soft airship away from the center of mass of the airship. As shown in FIG. Figure 3As shown, the vector thrust system 2 includes a thrust propeller, a thrust motor 22, a first vector rotary motor 23, a first worm 24, a first worm support 25, a first turbine 26, a first bearing, a vector thrust system mounting platform 27 and a first turbine shaft. The thrust propeller 21 is fixedly connected to the thrust motor 22, and the thrust motor 22 drives the thrust propeller 21 to rotate. The thrust motor 22 is fixedly connected to one side of the first turbine 26, and the center of the other side of the first turbine 26 is vertically fixedly connected to one end of the first turbine shaft 28. The other end of the first turbine shaft 28 is fixedly connected to the inner ring of the first bearing, and the outer ring of the first bearing is fixed on the vector thrust system mounting platform 27. The first turbine 26 and the first worm 24 match to form a turbine-worm pair, and the lower part of the first worm support 25 is fixedly connected to the vector thrust system mounting platform 27, and the upper part supports the first worm 24. The first vector rotary motor 23 is fixed on the vector thrust system mounting platform 27. One end of the first worm gear 24 is connected to the first vector rotating motor 23, and the first turbine 26 is driven by the first vector rotating motor 23 to rotate, thereby driving the thrust propulsion motor 22 to rotate around the axis of the first turbine shaft 28. The thrust bracket 6 is perpendicular to the plane where the first turbine 26 is located, so that when the first turbine 26 drives the thrust propulsion motor 22 and the thrust propeller 21 to rotate, the thrust propeller 21 rotates with the thrust bracket 6 as the axis. The thrust propeller 21 of the vector thrust system 2 can rotate with the thrust bracket 6 as the axis within a range of ±θ to adjust the pitch attitude of the airship, where θ is 90 degrees. When the vector thrust system 2 does not need to adjust the pitch attitude of the airship, the rotation angle of the vector thrust system 2 is 0 degrees, and the vector thrust system 2 provides the airship with power to fly forward. The forward thrust system 4 is fixed to both sides of the soft airship through the thrust bracket 6 to provide the airship with power to fly forward. In actual applications, multiple groups of forward thrust systems 4 can be set (one group is two forward thrust systems 4 symmetrically arranged on both sides of the airship). As shown in FIG. Figure 4 As shown, the forward thrust system includes a forward propeller 41, a forward propulsion motor 42 and a forward system mounting platform 43. The forward propeller 41 is fixedly connected to the forward propulsion motor 42, and the forward propulsion motor 42 drives the forward propeller 41 to rotate. The forward propulsion motor 42 is fixed on the forward system mounting platform 43, and the forward system mounting platform is fixedly connected to the thrust bracket 6. The plane formed by the rotation of the forward propeller 41 is parallel to the thrust bracket 6. Figure 1 and Figure 2 In the embodiment, the vector thrust system 2 is located at the front of the airship, and the forward thrust system 4 is located at the rear of the airship. In practical applications, the vector thrust system 2 can also be set at the rear of the airship, and the forward thrust system 4 can be set at the front of the airship. Figure 5As shown, the tail cone 10 is arranged at the tail of the blimp, corresponding to the nose cone 9. The tail cone 10 includes a hollow or solid rod-shaped structure and an aluminum alloy connector, and the tail cone 10 is tied to the outer surface of the outer capsule 7 by a bow tie and a lashing rope. The tail cone 10 is fixedly connected to the tail thrust bracket 5 through a tail cone support rod 16. The tail thrust bracket 5 is a rod-shaped structure or a truss structure, which can be a hollow tubular structure or a solid structure. The tail cone bracket 5 is made of carbon fiber, steel, aluminum alloy and / or titanium alloy, preferably carbon fiber and / or aviation aluminum alloy. The tail cone bracket 5 is parallel to the longitudinal axis of the blimp. The vector tail thrust system 8 is fixed to the tail cone 10 through the tail thrust bracket 5. As shown Figure 6 As shown, the vector tail thrust system 8 includes a tail thrust propeller 81, a tail thrust propulsion motor 82, a second vector rotary motor 83, a second worm 84, a second worm support 85, a second turbine 86, a vector tail cone system mounting platform 87, a second turbine shaft 88 and a second bearing. The tail thrust propeller 81 is fixedly connected to the tail thrust propulsion motor 82, and the tail thrust propulsion motor 82 drives the tail thrust propeller 81 to rotate. The tail thrust propulsion motor 82 is fixedly connected to one side of the second turbine 86, and the center of the other side of the second turbine 86 is vertically fixedly connected to one end of the second turbine shaft 88. The other end of the second turbine shaft 88 is fixedly connected to the inner ring of the second bearing, and the outer ring of the second bearing is fixed on the vector tail thrust system mounting platform 87. The second turbine 86 and the second worm 84 match to form a turbine-worm pair, and the lower part of the second worm support 85 is fixedly connected to the vector tail thrust system mounting platform 87, and the upper part supports the second worm 84. One end of the second worm 84 is connected to the second vector rotary motor 83, and the second vector rotary motor 83 is fixedly connected to the vector tail thrust system mounting platform 87. Driven by the second vector rotary motor 83, the second turbine 86 is rotated, thereby driving the tail thrust propulsion motor 82 to rotate around the axis of the second turbine shaft 88. The tail thrust bracket 5 is parallel to the plane where the second turbine 86 is located, so that when the second turbine 86 drives the tail thrust propulsion motor 82 and the tail thrust propeller 81 to rotate, the tail thrust propeller 81 rotates with the axis of the side thrust bracket 5 on the vertical plane as the axis. The tail cone propeller 81 of the vector tail thrust system 8 can rotate with the vertical line of the tail thrust bracket 5 on the vertical plane as the axis within a range of ±β to adjust the yaw direction of the airship, β is 90 degrees. The nose cone 9 is arranged on the outer capsule 7 at the front of the soft airship.

[0065] A plurality of reinforcing rings 3 are fixed in parallel on the outer capsule 7. Each reinforcing ring 3 is in the shape of a ring, and its center is located on the longitudinal axis of the soft airship. Figure 7 As shown, the reinforcement ring 3 is a hollow or solid structure. Figure 7The reinforcement ring 3 is a hollow tubular structure. The reinforcement ring 3 is made of carbon fiber, steel, aluminum alloy and / or titanium alloy, preferably carbon fiber and / or aviation aluminum alloy. Each first bow-knot 14 corresponds to a lashing rope 15, and every two first bow-knots 14 are respectively arranged on both sides of the reinforcement ring 3 and fixed to the outer surface of the outer capsule 7. One end of the lashing rope 15 is tied to one first bow-knot 14, and the other end is tied to another lashing rope 15, thereby fixing the reinforcement ring 3 to the outer surface of the outer capsule 7. Figure 1 and Figure 2 Two reinforcement rings 3 are provided, each reinforcement ring 3 is fixedly connected to a pair of side thrust brackets 6, each pair of side thrust brackets 6 includes two side thrust brackets 6, and the two side thrust brackets 6 are respectively provided on both sides of the airship. In practical applications, several reinforcement rings 3 can be provided near the side thrust brackets 6 and fixedly connected to the side thrust brackets 6, or reinforcement rings 3 not connected to the side thrust brackets 6 can be provided in other places to maintain the boat shape. Multiple side thrust brackets 6 can also be fixedly connected on each reinforcement ring to make the force on the airship more uniform.

[0066] The reinforcing ring 1 is arranged on the outer bladder 7 and is located at the connection between the reinforcing ring 3 and the side thrust bracket 6. The reinforcing ring 1 is fixed to the outer surface of the outer bladder 7 in the same manner as the reinforcing ring 3, and the reinforcing ring 1 is fixed by a bow tie and a lashing rope. Figure 8 As shown, the reinforcing ring 1 is circular, elliptical or rectangular with rounded corners, and the middle of the above shape is hollow, which is conducive to reducing weight. The connection between the reinforcing ring 3 and the side thrust bracket 6 is located in the reinforcing ring 1, preferably in the center. The reinforcing ring 1 is a hollow or solid rod-shaped structure, made of carbon fiber, steel, aluminum alloy and / or titanium alloy, preferably carbon fiber and / or aviation aluminum alloy. The reinforcing ring 1 is made of the same material as the reinforcing ring 3. The reinforcing ring support rod 13 is also located in the reinforcing ring 1, and the reinforcing ring support rod 13 is a hollow or solid rod-shaped structure, made of carbon fiber, steel, aluminum alloy and / or titanium alloy, preferably carbon fiber and / or aviation aluminum alloy. The way in which the reinforcing ring support rod 13 is fixed to the outer surface of the outer capsule 7 refers to the way in which the reinforcing ring 3 is fixed, and the reinforcing ring support rod 13 is fixed by a bow tie and a tying rope. One end of the reinforcing ring support rod 13 is fixedly connected to the reinforcing ring 1, and the other end is fixed to the connection between the reinforcing ring 3 and the side thrust bracket 6. One end of the side thrust bracket support rod 12 is fixedly connected to the reinforcing ring 1, and the other end is fixedly connected to the side thrust bracket 6. The side thrust bracket support rod 12 is a hollow or solid rod-shaped structure, made of carbon fiber, steel, aluminum alloy and / or titanium alloy, preferably carbon fiber and / or aviation aluminum alloy. Fig. 9The left, middle and right are respectively a four-way adapter, a five-way adapter and a six-way adapter. The four-way adapter, the five-way adapter and the six-way adapter are all made of aviation aluminum alloy. A four-way adapter, a five-way adapter or a six-way adapter is used to fix the reinforcing ring 1 and the reinforcement ring 3, between the reinforcement ring 3 and the side thrust bracket 6, between the reinforcing ring 1 and the reinforcement ring support rod 13, between the reinforcing ring 1 and the side thrust bracket support rod 12, and between the reinforcing ring support rod 13 and the reinforcing ring 3 and the side thrust bracket 6. One reinforcing ring 1 can be connected to multiple reinforcing rings 3, and multiple reinforcing rings 1 can also be set at the connection between the reinforcing ring 3 and the side thrust bracket 6, which is beneficial to improve the rigidity and stability of the place, but the weight will increase. Multiple reinforcing rings 1 can be fixed with reinforcing rings 1 of different diameters, referring to the fixing method of one reinforcing ring 1.

[0067] like Fig.10 As shown, the left side is an airship with a reinforcement ring 3 and a reinforcing ring 1, and the right side is an airship without a reinforcement ring 3 and a reinforcing ring 1. When the pressure difference between the inside and outside of the outer bladder 7 is small, the airship with the reinforcement ring 3 and the reinforcing ring 1 maintains the shape of the airship well, while the airship without the reinforcement ring 3 and the reinforcing ring 1 is deformed by the pressure, and the propeller of the airship interferes with the outer bladder 7 of the airship, which easily damages the outer bladder 7. It can be seen that a plurality of reinforcement rings 3 are arranged on the outer bladder of the soft airship to form a local frame, which can maintain the shape of the airship under the condition of a relatively low pressure difference, and is conducive to the wind-resistant flight of the airship at night; because the structure of the reinforcement ring 3 is adopted, the complex rigid frame structure of the rigid airship is abandoned, and weight is saved, and the saved weight can be used for the weight of the bladder material to strengthen the strength of the outer bladder. At the same time, the reinforcement ring 3 is connected to the side thrust bracket 6, and a reinforcement ring 1 is provided at the connection to increase the local stiffness of the joint between the outer bladder 7 and the side thrust bracket 6, so as to reduce the destructive effect of the bending moment generated by the bracket of the side thrust system on the shape of the stratospheric airship under the condition of a lower pressure difference between the inside and outside of the airship.
