Blast disruption using 3D grids/perforated plates for vehicle protection

In this work, blast disruption and mitigation using 3D grids/perforated plates were tested for underbelly and side protection of vehicles. Two vehicle simulants were used: a small-scale one for side vehicle protection assessment and a true-to-scale simulant for underbelly protection testing. The deformation of target plates was assessed. These were either unprotected or protected by three different types of disruptors. The first disruptor was made of a sandwich structure of two perforated plates...

The interaction between a shaped charge jet and a single moving plate

Reactive armour is a very efficient add-on armour against shaped charge threats. Explosive reactive armour consists of one or several plates that are accelerated by an explosive. Similar but less violent acceleration of plates can also be achieved in a completely inert reactive armour. To be efficient against elongated jets, the motion of the plates needs to be inclined against the jet such that a sliding contact between the jet and the plates is established. This sliding contact causes a deflec...     

Real-time localization for underwater equipment using an extremely low frequency electric field

A new real-time underwater equipment location method adopting an electric field induced by a standard current source is proposed. Our goals were real-time tracking and location of stationary or moving underwater equipment both in shallow and deep seas, under noisy conditions. The main features of this method are as follows:(1) a standard current source on the water surface, which can be towed by a vehicle, consisting of two electrodes, a signal generator, and a GPS unit;(2) measurement of the ex...     

Air combat target maneuver trajectory prediction based on robust regularized Volterra series and adaptive ensemble online transfer learning

Target maneuver trajectory prediction is an important prerequisite for air combat situation awareness and maneuver decision-making. However, how to use a large amount of trajectory data generated by air combat confrontation training to achieve real-time and accurate prediction of target maneuver trajectory is an urgent problem to be solved. To solve this problem, in this paper, a hybrid algorithm based on transfer learning, online learning, ensemble learning, regularization technology, target ma...     

Nacre-inspired interface structure design of polymer bonded explosives toward significantly enhanced mechanical performance

Realizing effective enhancement to the structure of interface region between explosive crystals and polymer binder plays a key role in improving the mechanical properties of the current polymer bonded explosives(PBXs). Herein, inspired by the structure of natural nacre which possesses outstanding mechanical performance, a kind of nacre-like structural layer is constructed in the interface region of PBXs composites, making use of two-dimensional graphene sheets and one-dimensional bio-macromolecu...     

Analysis of echo signal modulation characteristic parameters on aerial and space targets

Based on the scattering characteristic, the comparison of RCS(radar cross-section) at different positions of a target in the same direction of incidence can be obtained first by extruding or deleting part of the entity. A simulation method of aerial&space targets echo characteristics(A&STEC) is proposed that is universal to aerial and space targets. We utilize a fixed-wing UAV(unmanned aerial vehicle) and typical missiles in simulation. The echo signal modulation characteristic parameter...     

The Two Techniques of O. Henry''''s

O.Henry is the founder of American modern short story, What makes his stories enjoy most popularity is his own styles——(1)Reasonable artistic exaggreration. (2)Unexpected ending. In this article I emphatically comment its value in the two stories: The Romance of a Busy Broker and The Last Leaf. Up to Now there is still much in Henry's method that we can make use of beneficially.     

Cooperative UAV search strategy based on DMPC-AACO algorithm in restricted communication scenarios

Improvement of integrated battlefield situational awareness in complex environments involving dynamic factors such as restricted communications and electromagnetic interference(EMI) has become a contentious research problem. In certain mission environments, due to the impact of many interference sources on real-time communication or mission requirements such as the need to implement communication regulations, the mission stages are represented as a dynamic combination of several communication-av...

access to classified information - Theability and opportunity to obtain knowledge of classified information. Persons have access to classified information if they are permitted to gain knowledge of the information or if they are in a place where they would be expected to gain such knowledge. Persons do not have access to classified information by being in a place where classified information is kept if security measures prevent them from gaining knowledge of the information.     

Drop weight impact analysis of GFRP tubes with hollow glass particle-filled matrix

Protecting occupants or payloads in crashes and blasts is of utmost importance in both moving and immobile structures. One way of achieving this is by using a sacrificial energy absorber. Composite tubes have been studied as potential energy absorbers due to their ability to fail progressively under axial compression. In this study, the energy absorption capability of these tubes is enhanced by adding hollow glass particles to the matrix. Drop-weight tests are performed on composite tubes, and a...

Microwave absorption properties of carbonyl iron-based paint coatings for military applications

The paper explores the possibilities of using carbonyl iron in the form of a powder for the manufacture of radar-absorbing paints-reducing the radar signature of the objects that they cover. The attenuation values in the range of 4-18 GHz for various coating thicknesses, ranging from 0.5 to 2.00 mm with 0.5 mm increment, and for different absorber content-75% and 80%, as well as the use of two different binders in the form of epoxy resins with hardeners, were investigated. For the frequency of 1...     

Deep hybrid: Multi-graph neural network collaboration for hyperspectral image classification

With limited number of labeled samples, hyperspectral image(HSI) classification is a difficult Problem in current research. The graph neural network(GNN) has emerged as an approach to semi-supervised classification, and the application of GNN to hyperspectral images has attracted much attention. However, in the existing GNN-based methods a single graph neural network or graph filter is mainly used to extract HSI features, which does not take full advantage of various graph neural networks(graph ...
