This thesis addresses the driving forces behind the Swedish state?s procurement of Helicopters 14 and 16 and the decommissioning of Helicopter 4. These actions have significantly affected the Swedish Armed Forces, especially the Helicopter Wing, in carrying out their operational tasks. On numerous occasions the Helicopter Wing has been unable to perform its tasks. For instance, the Nordic Battle Group 08 had no helicopters to exercise with and, until recently, Sweden had completely lacked the ability to hunt submarines with helicopters for almost ten years.This thesis also aims to compare the decisions in 1999-2000 regarding Helicopter 14 with the decisions in 2010-2011 regarding the acquisition of Helicopter 16, to find if there is a general trend and how much the Armed Forces were able to influence decisions.

This study examines how the local rescue services relate to the brand of the rescue service and the concept of brand management. To understand the attitudes against the brand and brand management, empirical data, theoretical modelling of brand and current laws have been discussed together in a try to get an overview how the rescue services practically works with the brand. The study results are based on a questionnaire survey and qualitative semi-structured interviews. The survey was sent to employees working with the communication of the rescue service. The interviews were held with two employees working with the communication of the rescue service and two fire chiefs.

When a helicopter is flying, the dynamics vary depending on, for example, speed and position. Hence, a time-invariant linear model cannot describe its properties under all flight conditions. It is therefore desirable to update the linear helicopter model continuously during the flight. In this thesis, two different recursive estimation methods are presented, LMS (Least Mean Square) and adaptation with a Kalman filter. The main purpose of the system estimation is to get a model which can be used for feedback control.

AbstractThis report is about the creation of a test system for development of a control system for a off the shelf RC-helicopter, which can be bought for about two thousand SEK. The test system consists of both electronics for controlling the helicopter and mechanical constrainer. The constrainer is used for mounting the helicopter so that it won´t crash.A circuit board including processor and sensors was manufactured. This was used for doing test of the different control algorithms. In this way were we able to analyze the quality of the sensors chosen, and what other sensors that could contribute to the control of the system.Basic helicopter control have been studied and presented in the report.

The purpose of this legal dogmatic Bachelor Thesis is to define the legal definition of ?a rescue service? and illustrate the division of responsibilities between national authorities and the municipalities with regards to the execution of emergency response operations.?A rescue service? means the emergency response actions that national and municipal authorities are legally obliged to provide to prevent or minimise injury to people and damage to property or the environment when emergencies occur or seem imminent. In the following cases a national authority is responsible for providing the requisite rescue service:1. Search and rescue (air) ? the Swedish Civil Aviation Authority is the responsible authority;2.

Vid större olyckor och kriser kan Försvarsmaktens helikoptrar nyttjas för bland annat sjukvårds-, transport-,släck-, flygräddnings- och sjöräddningsuppdrag. Sedan 2010 är Rakel det kommunikationssystem som används av de så kallade blåljusorganisationerna (Polis, Räddningstjänst, Ambulans, etc) samt vid krisledning i Sverige. I och med införandet av Rakel tappade Försvarsmaktens helikoptrar förmågan att kunna kommunicera och samverka effektivt vid olyckor och kriser med blåljusorganisationerna. Rakel är operativt i Försvarsmakten och Helikopterflottiljen men systemet finns inte att tillgå i helikoptrarna där behovet är störst.Målet med detta examensarbete var att ta fram ett tekniskt och taktiskt underlag för att undersöka om det är möjligt att installera Rakelsystemet i Försvarsmaktens helikoptrar och undersöka behovsbilden av Rakel vid insatser av civil karaktär..

At the department of Electronic Warfare Assessments at the Swedish Defence Research Agency in Linköping one of the activities is modelling and simulation of the duel between a robot and a target. The aim with this Master's thesis is to develop a simulation model of an hovering helicopter. First a theoretical description of the forces and moments acting on an helicopter is given. Then the equations of motion are derived. These equations are simplified to be valid only for a hovering helicopter and the result is a mathematical model.

This report consists of a discussion about suitable methods for studying complex sociotechnical systems that are still being developed. There are large economical advantages with studying new systems before they are completely developed since problems can be discovered early and thereby avoided. It is, however, difficult to study developing systems, there are methodological limitations. These limitations are discussed and recommendations for studying non-existing complex sociotechnical systems are presented.The report is based on experiences from a study of the introduction of a shipboard helicopter on the corvettes that the Swedish Armed Forces are developing. A shipboard helicopter implies high requirements on the hosting ship.

This report describes the construction work of a radar antenna for the radar systemCARABAS. CARABAS is a long wave airborne ground radar that has been developed bySAAB Microwave Systems and will now be mounted on a small helicopter, Schweizer 300.The antenna should be able to fold up and down. When the radar is in use the antenna islowered and under transport, start and landing the antenna is folded up. An emergency dropfunction should also be included in the design of CARABAS III.The extent of this report includes construction of the antenna, frame structure attached to thehelicopter, mechanism for folding the antenna up and down and mechanism for emergencydrop function. The mechanical design of the antenna and frame structure is based on modaland stress analysis, vibration measurement of Schweizer 300 and frequency analysis, andcalculations regarding aerodynamic drag and mechanics.The exciting frequencies of the helicopter and accelerations at those frequencies weredetermined by vibration measurement and frequency analysis.

This report is a part of the process of enhanced cooperation between fire rescue services in the region of North West Scania. The aim of the report is to study and analyze how the fire rescue service should be structured, in terms of rescue units and personnel, if no account is to be taking to the current organization. Two types of accident are considered in the report, traffic accidents and building fires. These are more affected by decreased response time than other accidents. Several suggested organizations are presented and they are evaluated with the computer program REP.

The purpose of this report is to study the relationship between the rescue service fire prevention activities and the number of arson fires in schools. An objective of the project is also to investi-gate the need of developing national methods for fire prevention. The results are based on a questionnaire study among 35 fire departments and further interviews with five of them. The results indicate that there is a relationship between the rescue service fire prevention activities and the number of arson fires in schools. The relationship is positive in the sense that arson fires in schools decrease with increasing prevention activities.

This study was carried out as a commission from Holmen Skog, district ?Egen skog? in Norrköping. During October 2006 several stands were inventoried by aerial photos from helicopter. The stands were those for which the next action proposed was plant inventory or plant check. The photos were interpreted and the number of stems was calculated.

This thesis deals with the documentation of non-prioritised material during archaeological fieldwork. The main questions are whether there is a difference in the documentation of the non- prioritised material, between rescue archaeology and research archaeology and what the reasons for such a difference may be related to. Furthermore, the thesis deals with what arch-aeologists write say and do about the subject. To answer these questions, I analyse three different projects; Two research projects, Zvejnieki (Latvia) and Monte da Igreja (Portugal), and one rescue archaeological project, Gyllins Trädgård (Sweden).The most important result is that there is as great a difference between the two research projects as there is between the research projects and the rescue archaeological project. Many similarities can be seen in the projects conducted at Monte da Igreja and Gyllins Trädgård.

Mellan år 1987 och 2000 fanns ett beväpnat helikopterförband inom arméflyget. Dessa två pansarvärnshelikopterkompanier användes för att bekämpa stridsfordon. Efter nedläggningen har Sverige inte haft en helikopter med beväpning för annat än egenskydd.Uppsatsen syftar till att utifrån William S. Linds teori om manöverkrigföring utvärdera om pansarvärnshelikopterkompanierna framgångsrikt bidrog till att besegra motståndaren.Det framkommer att pansarvärnshelikopterkompaniernas taktik väl stämmer överrens med Linds teori vilket pekar på att bestyckade helikoptrar är ett mycket användbart instrument inom manöverkrigföringen.  .

In order to reduce the number of casualties and injured from accidents the rescue service must become more efficient and flexible. It is noted that far more people is injured and killed in traffic accidents than from fires. During the daytime the number of accidents in about three times higher than during the night, even so today the number of fire fighters on duty is the same day and night.Two computer models for simulation of different locations of the rescue services are used to determine the best options for placement of the rescue services. A cost-benefit analysis is also used to determine if today's fire stations are efficient for the society from an economical point of view.The results of the different models are that the fire station in Lund is misplaced. The number of ladders in Malmö can be reduced.
