Erfarenheter från en studie av införandet av ombordbaserad helikopter på korvett av Visbyklass
… 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. Three different types of requirements were studied …
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 …
… 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 …
… 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 …
A helicopter based system equipped with a millimetre-wave fire control radar is studied for improvement of the detection probability for moving ground targets. The system is a pulse doppler radar that sends out the electromagnetic wave in repetitive pulses. The frequency in …

… with varying expected growth responses. Both ash spreading with tractor and helicopter were investigated. The NPV was calculated with and without law restrictions (3 tons of ash/ha during the whole rotation period and 5 tons of ash/ha every 30 years, respectively). These two …
Ett instrument för manöverkrigföring?
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 …
… Jonnie Friberg, the planning started to try inventory in pictures taken from a helicopter. The pictures was at last taken from a digtal camera and the vegetationheight was mesured with a laser. The gear was supplied from Kallax Flyg AB, Luleå. In the trial 15 stands was selected …
… the Swedish Air Force rescue services against crashed military aeroplanes and helicopters. The aim of the report is to study and analyze the tactics used by the different Air Force bases, standards, regulations and equipment. The report also discusses the different work …
en konceptuell fallstudie av Saabs UAV-system Skeldar M
Den senaste trenden inom flygvapenindustrin är utveckling av obemannade farkoster. 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 …
… was also investigated.Laser data and aerial photographs were collected from a helicopter operating at an approximate height of 100 meters. In total, data were collected for 48 of Holmen Skog’s young stands in Västerbotten and 21 of these were selected for the study (including …
Modern krigföring genomförs till stor del i form av gemensamma operationer. Helikoptern är en relativt ny tillgång i modern krigföring men används i stor utsträckning för olika uppgifter. Helikopterns förmåga att flyga men ändå bibehålla en nära kontakt med markstyrkorna har …
