ABSTRACT (maximum 200 words) The goal of this research is to perform a cost-effectiveness analysis of selected aerial platforms and suitable communication payloads for use as communication relays in support of distributed military operations. Aerial platforms, for the purpose of this study, include UAVs, towers and aerostats. A multi-objective analysis is utilized to compare dissimilar attributes together among the alternatives. Cost data for each system considered is presented. To analyze the cost-effectiveness of alternatives for different mission sets, three hypothetical scenarios are used including disaster relief, long-range relay, and the tactical user. This research identifies the most cost-effective aerial platforms and communication payloads for each scenario based on the authors’ preferences. Future decision makers can utilize this study as a decision tool to match their own preferences. 14. SUBJECT TERMS Unmanned Aerial Vehicle, UAV, Unmanned Aerial System, UAS, 15.

  • An Unmanned Aircraft System for Maritime Search and Rescue
    An Unmanned Aircraft System for Maritime Search and Rescue by Andre Paul Meredith Thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Engineering at Stellenbosch University Supervisor: Prof Thomas Jones Department of Electrical and Electronic Engineering March 2011 Declaration By submitting this thesis electronically, I declare that the entirety of the work contained therein is my own, original work, that I am the sole author thereof (save to the extent explicitly otherwise stated), that reproduction and publication thereof by Stellenbosch University will not infringe any third party rights and that I have not previously in its entirety or in part submitted it for obtaining any qualification. Date: March 2011 Copyright © 2011 Stellenbosch University All rights reserved i Abstract Search and Rescue is an essential service provided by States and Militaries to search for, locate and rescue survivors of accidents and incidents. Civil Search and Rescue utilizes a system of well-trained professionals or volunteers, an effective Search and Rescue organization, supported by industry and other providers of infrastructure and assets. The service is rendered to save the lives of civilian individuals in imminent danger of losing their lives. Military (Combat) Search and Rescue is provided by militaries to save the lives of military practitioners in a similar predicament. In addition, Search and Rescue is performed over land and over the sea. All forms of Search and Rescue rely on capable, specialized assets for efficiency en affectivity. Assets are specified and chosen on the grounds of various factors, amongst others operating environment, operational profile, performance and special abilities.

Den svenska vapenindustrikoncernen Saab AB följer denna trend i och med den stundande introduktionen av företagets obemannade helikopter Skeldar V-150. Som ett led i vidareutvecklingen av detta system finns planer på att även lansera en marin variant, kallad Skeldar M. Tanken med denna marina variant är att möjliggöra fullständigt autonoma starter och landningar från fartyg. För att kunna genomföra detta på ett tryggt sätt även i hårt väder krävs att helikoptern hålls säkrad på fartygsdäcket såväl innan start som efter landning.

Niiden avulla pystytään vähentämään operaatioissa ihmisohjaajaan kohdistuvia riskejä, mikä on tärkeää erityisesti nykyaikaisissa matalan intensiteettitason konflikteissa. Kiinteäsiipiset UAV:t ovat jo vakiinnuttaneet asemansa taistelukentällä, mutta miehittämät- tömät helikopterit ovat vasta viime vuosikymmenellä kehittyneet tasolle, joka mahdollistaa niiden operatiivisen käytön. Tutkielmassa tarkastellaan miehittämättömien helikoptereiden kehitystä ja vastataan pääkysymykseen: Miten miehittämättömien helikoptereiden suoritus- kyky on kehittynyt valittuna ajanjaksona? Lisäksi selvitetään kahden alakysymyksen avul- la, mihin suorituskyvyn kehittyminen pohjautuu ja mistä suorituskyvyn eri osa-alueiden kehitystarve johtuu. Tutkimusmenetelmänä tutkielmassa käytetään laadullista kirjallisuustutkimusta ja laadullis- ta sisällönanalyysiä.
