This disclosure relates generally to aircraft and, more particularly, to adapter assemblies for aircraft and launchers for deploying aircraft.
Some aircraft, such as unmanned aerial vehicles (UAVs), are deployed with a launcher. The launcher accelerates the UAV to a relatively high speed within a short distance. This eliminates the need for a runway to deploy the UAV.
An example adapter assembly for an unmanned aerial vehicle (UAV) is disclosed herein. The adapter assembly includes a first adapter to be removeably coupled to a first side of a fuselage of the UAV. The first adapter includes first and second posts to interface with a carriage of a launcher. The adapter assembly also includes a second adapter to be removeably coupled to a second side of the fuselage of the UAV. The second adapter includes third and fourth posts to interface with the carriage of the launcher.
An example system disclosed herein includes a launcher to deploy an unmanned aerial vehicle (UAV). The launcher includes a moveable carriage. The system also includes a first adapter to be removeably coupled to a first side of a fuselage of the UAV. The first adapter includes a first post to interface with the carriage. The system further includes a second adapter to be removeably coupled to a second side of the fuselage opposite the first side. The second adapter includes a second post to interface with the carriage.
An example method disclosed herein includes removeably coupling a first adapter to a first side of a fuselage of an aircraft. The first adapter includes first and second posts. The method also includes removeably coupling a second adapter to a second side of the fuselage of the aircraft opposite the first side. The second adapter includes third and fourth posts. The method further includes setting the aircraft on a carriage of a launcher and launching the aircraft with the launcher.
The figures are not to scale. Instead, the thickness of the layers or regions may be enlarged in the drawings. In general, the same reference numbers will be used throughout the drawing(s) and accompanying written description to refer to the same or like parts.
Unless specifically stated otherwise, descriptors such as “first,” “second,” “third,” etc. are used herein without imputing or otherwise indicating any meaning of priority, physical order, arrangement in a list, and/or ordering in any way, but are merely used as labels and/or arbitrary names to distinguish elements for ease of understanding the disclosed examples. In some examples, the descriptor “first” may be used to refer to an element in the detailed description, while the same element may be referred to in a claim with a different descriptor such as “second” or “third.” In such instances, it should be understood that such descriptors are used merely for identifying those elements distinctly that might, for example, otherwise share a same name.
A fixed wing aircraft, such as a fixed wing unmanned aerial vehicle (UAV) (e.g., a drone), is typically deployed from a runway or airstrip, similar to a commercial aircraft. However, this method of deploying a fixed wing UAV requires a relatively large amount of space to accommodate a runway. In other words, a relatively flat and open space is needed to launch the UAV. In many instances, such as in reconnaissance missions, runways are not readily available. Further, launching a UAV from an airstrip may result in the UAV and/or a remote operation station being exposed.
Some examples systems (e.g., an unmanned aerial system (UAS)) include a launcher to deploy a UAV. The launcher includes a carriage that is moveable along a track, which is relatively short compared to a runway. The UAV is set on or attached to the carriage, and the carriage accelerates rapidly along the track to propel the UAV into the air. Known launcher manufacturers provide specific UAVs with integrated structures or points for interfacing with their carriages. Therefore, only the manufacturer's UAVs can be launched from the launcher. However, other UAV manufacturers or UAV operators desire to utilize various launchers with their UAVs.
Disclosed herein are example adapter assemblies (which may also be referred to as adapters, brackets, or interfaces) that be used on various aircraft, such as a UAVs, to enable the UAVs to be deployed with a launcher. The example adapter assemblies can be removeably coupled to a UAV and interface with the specific structures on the carriage of the launcher. This enables UAVs that are not specifically designed or built for a specific launcher to be launched or deployed on the launcher. Further, various adapter assemblies can be constructed so that the same UAV can be launched with various types or styles of launchers. Further, the example adapter assemblies are removeably coupled to the UAV, such that the adapter assembly can be removed after use. This reduces the footprint and allows flexibility for on-site selection of a launcher and adapter.
The system 100 includes a launcher 104 to launch or deploy the UAV 102. In the illustrated example, the launcher 104 includes a track 106 and a carriage 108 that is moveable along the track 106. In some examples, the launcher 104 is pneumatically powered by a control module 110. When activated, the control module 110 supplies high pressure fluid (e.g., to a piston inside of the track 106) to rapidly accelerate the carriage 108 along the track 106. In the illustrated example, the carriage includes a first set of arms 112a, 112b and a second set of arms 114a, 114b (labeled in
As an example use application, the UAV 102 is set on the carriage 108. For example, as shown in
In some examples, the first and second posts 304a, 304b have the same cross-sectional shape and size. However, in other examples, such as shown in
In the illustrated example, the adapter assembly 116 includes a second adapter 306 that is substantially the same as the first adapter 300 (except the arrangement of the posts is mirrored). Thus, any of the example structural and/or functional features disclosed in connection with the first adapter 300 can likewise apply to the second adapter 306. The second adapter 306 includes a second plate 308 and third and fourth posts 310a, 310b (the third post 310a is shown in
In some examples, instead of the posts 304a, 304b, 310a, 310b interfacing (e.g., contacting) the interface points of the carriage 108, the adapter assembly 116 includes one or more bolts (e.g., shoulder bolts) that can interface with the interface points on the carriage 108. For example, as shown in
In some examples, the first and second adapters 300, 306 are constructed of aluminum. In other examples the first and/or second adapters 300, 306 are constructed of one or more materials, such as titanium or a composite (e.g., carbon fiber).
In some examples, to removeably couple the first and second adapters 300, 306 to the fuselage 118 (
In some examples, the adapter assembly 116 includes a first spacer 314 and a second spacer 316 to be disposed around the top and bottom sides of the fuselage 118 (
In the illustrated example, the first spacer 314 is disposed on a top side of the fuselage 118 between the fuselage 118 and the clamp 312. Further, the second spacer 316 is disposed on a bottom side of the fuselage 118 between the fuselage 118 and the clamp 312. As disclosed above, the first and second spacers 314, 316 fill any gap or space between the clamp 312 and the fuselage 118. The clamp 312 encircles the fuselage 118 and is tightened to clamp the first and second adapters 300, 306 to the sides of the fuselage 118, thereby removeably coupling the first and second adapters 300, 306 to the fuselage 118 for the UAV 102. In some examples, the clamp 312 is positioned between the posts of the first and second adapters 300, 306. In other examples, the clamp 312 can be positioned outside of the posts (e.g., closer to one end of the first and second adapters 300, 306). In some examples, multiple clamps can be used (e.g., two or three clamps can be used). In some examples, in addition to or as an alternative to the clamp 312, one or more threaded fasteners (e.g., bolts) can be threaded through the first and second adapters 300, 306 and into the sides of the fuselage 118 to removeably coupled the first and second adapters 300, 306 to the UAV 102.
In some examples, various adapter assemblies can be designed for different launchers that have different interface points. Depending on the type of launcher being used, the corresponding adapter assembly can be coupled to the UAV 102. For example, a first type of adapter assembly can be removeably coupled to the UAV 102 and used when launching the UAV 102 with a first type of launcher. Then, the first type of adapter assembly can be removed and a second type of adapter assembly can be removeably coupled to the UAV 102 and used when launching the UAV 102 with a second type of launcher. As a result, the UAV 102 can be used with any type or style of launcher. Further, an adapter assembly can be removed from the UAV 102 and coupled to another UAV 102. Thus, the adapter assemblies disclosed herein are easily transferable.
Also, because the adapter assembly 116 is not permanently coupled to the UAV 102, the adapter assembly 116 can be removed when not being used with the launcher 104. For example, if the UAV 102 is being deployed via a regular runway, the adapter assembly 116 can be removed, which reduces weight and drag of the UAV 102.
An adapter assembly, such as the adapter assembly 116, can be selected on site or off site for compatibility with a particular launcher. At block 702, the first adapter 300 is removeably coupled to a first side of the fuselage 118 of the UAV 102. At block 704, the second adapter 306 is removeably coupled to a second side of the fuselage 118 of the UAV 102. In some examples, the first and second adapters 300, 306 are removeably coupled to the fuselage 118 of the UAV 102 using the clamp 312. For example, the first adapter 300 can be held (e.g., via a user or a temporary fixing mechanism) on the first side of the fuselage 118, and the second adapter 306 can be held on the second side of the fuselage 118. Then, the clamp 312 is placed around the fuselage 118 and the first and second adapters 300, 306. The clamp 312 is tightened, thereby coupling the first and second adapters 300, 306 to the UAV 102. In some examples, prior to tightening the clamp 312, the first and second spacers 314, 316 are placed around the top and bottom sides of the fuselage 118.
At block 706, the UAV 102 is set on the carriage 108 of the launcher 104. For example, the first and second posts 304a, 304b of the first adapter 300 are set in the interface points (e.g., notches) of the first set of arms 112a, 112b, and the third and fourth posts 310a, 310b of the second adapter 306 are set in the interface points (e.g., notches) of the second set of arms 114a, 114b. Thus, the first and second adapters 300, 306 enable the UAV 102 to interface with the carriage 108 and support the UAV 102 on the carriage.
At block 708, the launcher 104 is activated (e.g., via the control module 110) to launch the UAV 102. After the UAV 102 lands and the flight is over, at block 710, the first and second adapters 300, 306 can be removed from the UAV 102. For example, the clamp 312 can be loosened, and the first and second adapters 300, 306 can be taken off of the sides of the fuselage 118. The adapter assembly 116 can be used again with the UAV 102 or with another UAV. Further, another adapter assembly can be removeably coupled to the UAV 102 and used to launch the UAV 102 from another type of launcher.
“Including” and “comprising” (and all forms and tenses thereof) are used herein to be open ended terms. Thus, whenever a claim employs any form of “include” or “comprise” (e.g., comprises, includes, comprising, including, having, etc.) as a preamble or within a claim recitation of any kind, it is to be understood that additional elements, terms, etc. may be present without falling outside the scope of the corresponding claim or recitation.
