Abstract

Purpose

To provide an effective design methodology focused on loading structure of unmanned aerial vehicles with a special emphasis on MALE class platform.

Design/methodology/approach

Selected design methods and numerical calculations used during the development of two different class (MALE PW‐103 and HALE PW‐114) unmanned aerial vehicles have been described and discussed. The initial loading structure was set‐up coming from a steady state level flight condition.

Findings

Aeroelastic analysis showed that the wing torsional rigidity is not sufficient. To increase the critical flutter speed the wing sandwich skin has been reinforced adding extra layers of carbon fibres. This procedure is iterative by nature, because adding the new layers changes the weight and stiffness of aircraft and the critical flutter speed has to be computed again.

Research limitations/implications

Analysis and design methodology is limited to surveillance and monitoring platforms, where the design objectives are long endurance, high reliability and cost effectiveness of the platform.

Practical implications

A very useful source of design information and patterns to follow, especially for engineering students and engineers dealing with unmanned aviation.

Originality/value

This paper offers practical help for designers planning an unmanned platform to be well adjusted to the assumed mission, giving a lot of practical information about attachments and fittings, on‐board systems integrated with loading structure and integration of composites with metal parts in modern flying platforms.

Abstract

Purpose

To provide an effective numerical method for analysis and design of aerodynamic characteristics of unmanned aerial vehicles basing on commercial package VSAERO.

Design/methodology/approach

Calculation was made by VSAERO package, which is based on a classical panel method enhanced on boundary layer method. Paper explains how to use efficiently VSAERO package, which utilizes advanced CAD techniques, in modern designing of unmanned aircraft.

Findings

During aerodynamic analysis of unmanned aircraft the computing cycle is repeated many times until the required accuracy is obtained and when the best performance of an aircraft is achieved. Design process depends on the number of iterations. If the preliminary configuration (the so‐called starting design point) is well selected and the aerodynamic analysis is completed in a relatively short time, then the overall design time will be shortened.

Research limitations/implications

The panel method is very useful tool in spite of different limitations. For example, the Reynolds number has to be sufficiently high, angles of attack and sideslip have to be small enough. Computational process is relatively fast and the accuracy depends on the geometry representation. The boundary layer included into the computational model improves the accuracy of aerodynamic calculations. This methodology is limited to subsonic and low transonic speeds.

Practical implications

A very useful source of computational information and patterns to follow, especially for engineering students and engineers dealing with aerodynamic of unmanned aviation. Surface panel geometry can be transferred from UNIGRAPHICS via IGES files or can be generated from scratch using SPING or PEP software.

Originality/value

This paper offers a practical help for designers planning to develop a new unmanned platform. VSAERO package appeared to be a very useful tool for aerodynamic calculation in the full cycle design activity. This software utilizes the panel method enhanced on a boundary layer model for determination of the fundamental aerodynamic characteristic of an arbitrary aircraft. Presented paper shows a very efficient way how to compute the aerodynamics necessary for design of a new MALE class UAV.

Abstract

Purpose

The purpose of this paper is to consider the existing literature surrounding the use of technology in today’s society to inform future developments across emergency services. Reference to the Police Service in particular will have a resonance for many other public agencies who are utilising more and more technology.

Design/methodology/approach

Literature from a policing background will be reviewed to discover the positive impacts and benefits attached to its use, the potential obstacles to its implantation, and how lessons from one agency may be of benefit to others.

Findings

The findings suggest that there appears to be attention required in the application of technology by public agencies, namely, workforce culture, training and budgets, and legislation which need to be addressed if the use of technology by public agencies is to be successful.

Originality/value

This paper seeks to learn lessons for the implementation technology by a public agency, namely, the police, in an attempt to inform other public bodies. By doing so, it is believed the lessons learned will make the application of such technologies more effective.

Abstract

Purpose

The authors present a low-cost unmanned aerial vehicle (UAV) for autonomous flight and navigation in GPS-denied environments using an off-the-shelf smartphone as its core on-board processing unit. Thereby, the approach is independent from additional ground hardware and the UAV core unit can be easily replaced with more powerful hardware that simplifies setup updates as well as maintenance. The paper aims to discuss these issues.

Design/methodology/approach

The UAV is able to map, locate and navigate in an unknown indoor environment fusing vision-based tracking with inertial and attitude measurements. The authors choose an algorithmic approach for mapping and localization that does not require GPS coverage of the target area; therefore autonomous indoor navigation is made possible.

Findings

The authors demonstrate the UAVs capabilities of mapping, localization and navigation in an unknown 2D marker environment. The promising results enable future research on 3D self-localization and dense mapping using mobile hardware as the only on-board processing unit.

Research limitations/implications

The proposed autonomous flight processing pipeline robustly tracks and maps planar markers that need to be distributed throughout the tracking volume.

Practical implications

Due to the cost-effective platform and the flexibility of the software architecture, the approach can play an important role in areas with poor infrastructure (e.g. developing countries) to autonomously perform tasks for search and rescue, inspection and measurements.

Originality/value

The authors provide a low-cost off-the-shelf flight platform that only requires a commercially available mobile device as core processing unit for autonomous flight in GPS-denied areas.

Abstract

Purpose

There has been a lack of meaningful information systems architecture, which comprehensively conceptualise the essential components and functionality of an information system for fire emergency response addressing needs of different job roles. The purpose of this paper is to propose a comprehensive information systems architecture which would best support four of the key firefighter job roles.

Design/methodology/approach

The study has built on the outcomes of two previous preliminary studies on information and human-computer interaction needs of core firefighter job roles. Scenario-based action research was conducted with firefighters in a range of roles, to evaluate human-computer interaction needs while using various technology platforms.

Findings

Several key themes were identified and led us to propose several layers of an integrated architecture, their composition and interactions.

Research limitations/implications

The selected fire scenarios may not represent every type of fire expected in high-risk built environments.

Practical implications

The current paper represents a shared discussion between end users, system architects and designers, to understand and improve essential components. It therefore provides a reference point for the development of information system architecture for fire emergency response.

Originality/value

The proposed information system architecture is novel because it outlines specific architectural elements required to meet the specific situation awareness needs of different firefighters job roles.

Abstract

Purpose

construction industry in the Gulf Cooperation Council (GCC) member countries is at the peak as the region is in the stage of developing its infrastructures. Apart from some positive sign of this boost, several other issues have also been developed in the region. One of such issues is the safety of workers at the construction sites. This article, based on a variety of applications of drones in other industrial sectors, considers the use of drones for construction safety improvement in the GCC countries. This article aimed to investigate the safety-related applications of drones considering technical features and barriers and enablers for safety-related tasks.

Design/methodology/approach

A mixed research approach using both qualitative and quantitative methods was adopted to achieve the aims and objectives of this research. Data were collected through a systematic literature review, semistructured interviews and using a structured questionnaire. A total of 37 relevant research items and 10 interviews were held with construction safety professionals, and 92 responses collected from the safety managers through a structured questionnaire was used to derive the conclusion of this research. The collected data were processed and analyzed using the Statistical Product and Service Solutions (SPSS) program. Descriptive analyses were carried out in which means and importance factors were calculated.

Findings

25.92% of participants confirmed that they or their company had used the drone in different activates. The most common application of drones reported by the respondents was photography for marketing purposes followed by surveying application and quality inspections. The camera movability was the top-rated technical feature required for safety-related inspections. Similarly, “Working near the corner or edge of unprotected opening” was the top-rated application of drone for safety-related tasks. The safety concerns of using drones at job sites were rated as the most important barrier by the participants. Technical challenges associated with the use of drones for safety improvement was rated as the second most important barrier by the participants.

Research limitations/implications

Although, the research presented in this article is based on the GCC construction industry, however, since the data collected through systematic review and semistructured interviews are not a regional base, therefore the finding of this research could also be useful in other regions. Further research however, needs to be conducted to reduce the implications of the barriers identified in this paper so that the drone can be effectively used for safety improvement in construction not only in the GCC region but also in other countries.

Practical implications

Once the GCC construction industry will be able to overcome the challenges associated with the application of drones in safety improvement, the safety managers will be able to monitor the site more effectively which could be helpful to improve the safety performance of the construction organization.

Social implications

Improved safety performance in not only in the greater interest of the construction organizations as they can reduce the costs associated with poor safety but can also avoid the delay caused by construction accidents. Similarly, improved safety performance reduces the accidents at construction sites, and thus reduces injuries and disabilities caused by such accidents, making the construction workers a useful part of the society. The application of drones in safety-related tasks is one of the key solutions that can lead us to improved safety performance.

Originality/value

Although, the use of drone technology has revolutionized a number of industrial sectors due to its variety of applications, the application in construction particularly in the GCC region is still very limited. As noted in the results of this research, only 21 participants (25.92%) expressed that they or their company had used the drone in different activates. This means that the industry is not getting the full advantage of the available drone technology. The results of this research will enable construction industry stakeholders to know the challenges associated with the application of drones for safety improvement and to develop strategies to overcome these challenges.
