Pojikar, Pavel January 2011 (has links) The Thesis with title " Armament production for Whermacht and the Army of Aliance in Protectorate of Bohemia and Moravia (1939 - 1945) is interested in detailed description of armament production within quality and quantity armoured of vehicles and infantry weapons made in war years 1939 - 1945 in Czech munition factories. Foreword part deals with Czech production efore Munich agrément,suitable conditions for militarization and empowerment German Army nor the use in industry either for strategy location. In following chapters the work describes main munition factories (Škoda Plzeň - Skoda Werke, ČKD Praha - BMM, Munition faktory Brno)and due to occupation our country,Czechoslovakia,maximal use of technical and human potenciál in Protectorate.The same it documents sale of spare weapons (cannons and munition) and presents German production,too. In other chapters it directs to confrontal of weapons,thein improvement,following development,army tanks, (mainly tank ŠKODA vz. 35, tank ŠKODA vz. 35,light tank LT vz. 38 and later fighter tank and offensive cannons from útočná ČKD Prague , Marder III, Hetzer, Grille), infantry weapons made in Brnopěchotní (Carabine Mauser K98 and gunmachine MG34, MG42, MG131).

112	The forgotten Air Force : the establishment and employment of Australian air power in the North-Western area, 1941-1945 Helson, Peter, History, Australian Defence Force Academy, UNSW January 1997 (has links) The air campaign conducted by the RAAF in the North-Western Area during the Second World War has been largely ignored by historians yet it contributed significantly to the outcome of the Pacific war. This thesis sets out to discuss the campaign by considering various factors that impacted on the RAAF in the lead up to and during the course of the Pacific war and their relevance to the campaign. It looks at the way air operations were conducted in the North-Western Area between 1942 and 1945 and describes the role played by the flying squadrons based in the area. Using primary sources such as operational record books, documents and files at archives and libraries and interviews with veterans and experts the thesis found that the campaign was conducted in several phases. It started with the defence of Darwin. In keeping with overall allied strategy the RAAF then went on an offensive into what was then the Netherlands East Indies (NEI) using medium and heavy bombers and mine laying sea planes flying from bases in Australia???s north west. The NEI was vital to the Japanese war effort as a source of essential raw materials such as oil, timber, and rubber. To defend this part of their new empire the Japanese had amassed large military garrisons on the islands. The vessels used to transport troops and materials became the most important targets for the RAAF???s bomber squadrons. As General MacArthur???s forces advanced along the north coast of New Guinea the North-Western Area based units conducted raids into the NEI to deceive the Japanese into thinking an invasion would be launched from Darwin. As the New Guinea campaign gained momentum the RAAF???s task was to protect its western flank, to prevent the Japanese from moving troops and aircraft east to the Philippines. The thesis concludes the campaign was successful because Darwin was defended, it denied the Japanese vital materials for the conduct of the war and it kept hundreds of aircraft and tens of thousands of troops away from the allied advance.

114	Exploring feasibility of reinforcement learning flight route planning / Undersökning av använding av förstärkningsinlärning för flyruttsplannering Wickman, Axel January 2021 (has links) This thesis explores and compares traditional and reinforcement learning (RL) methods of performing 2D flight path planning in 3D space. A wide overview of natural, classic, and learning approaches to planning s done in conjunction with a review of some general recurring problems and tradeoffs that appear within planning. This general background then serves as a basis for motivating different possible solutions for this specific problem. These solutions are implemented, together with a testbed inform of a parallelizable simulation environment. This environment makes use of random world generation and physics combined with an aerodynamical model. An A* planner, a local RL planner, and a global RL planner are developed and compared against each other in terms of performance, speed, and general behavior. An autopilot model is also trained and used both to measure flight feasibility and to constrain the planners to followable paths. All planners were partially successful, with the global planner exhibiting the highest overall performance. The RL planners were also found to be more reliable in terms of both speed and followability because of their ability to leave difficult decisions to the autopilot. From this it is concluded that machine learning in general, and reinforcement learning in particular, is a promising future avenue for solving the problem of flight route planning in dangerous environments.

116	Conceptual Design of an Air-Launched Three-Staged Orbital Launch Vehicle / Konceptuell Design av en Luftlanserad Trestegsraket Rasmussen, Måns January 2021 (has links) The objective of this study was to design a launch vehicle capable of deploying a nanosatellite into a Sun-synchronous orbit at 500 km orbital altitude from the JAS 39E/F Gripen fighter aircraft. This was achieved by first performing theoretical calculations for the required nozzles and solid propellant grain configurations for the first two solid stages, followed by the necessary liquid propellant configuration for the third stage. Lastly, two methods were investigated in solving the trajectory ascent problem for the launch vehicle design. First, by stating the trajectory problem as an initial value problem while guessing a Sigmoidal steering law. Secondly, by stating the trajectory problem as a boundary value problem. The latter was solved by transcribing the trajectory problem into a nonlinear program where a parametric steering law was derived using a Sequential quadratic programming algorithm.Ultimately, resulting in a launch vehicle design with a gross lift-off mass of 1,289 kg, capable of launching an 8.4 kg payload into the targeted orbit, with suggested modifications to increase the possible payload mass to 12.9 kg. / Målet med den här studien var att designa en luftlanserad trestegsraket kapabel till att transportera en nanosatellit upp till en solsynkron omloppsbana på 500 km altitud från ett JAS 39E/F Gripen jaktflygplan. Det gjordes genom att först beräkna de nödvändiga dysorna och krutladdningsformerna för de två första stegen tillsammans med en flytande bränsledesign för det tredje steget. Två metoder undersöktes för bananalysen. Först genom att anta en Sigmoidal styrningsfunktion för pitchen, sedan genom att transkribera problemet till ett icke-linjärt program där en parametrisk styrlag togs fram genom att använda en Sequential quadratic programming algoritm. Slutligen presenterades en raketdesign med en total vikt på 1 289 kg, kapabel till att skjuta upp en nyttolast på 8,4 kg till den önskade omloppsbanan tillsammans med förslag som kan öka den möjliga nyttolasten till 12,9 kg.
