1. Aerodynamic studies of the flutter behavior of a compressor jet engine : Establishment of 1D criteria for the appearance of flutter within low pressure compressors
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Turbojet compressors are subject to numerous vibration phenomena that limit their good operability. Among these different phenomena, flutter is a major concern during the study and design phase. This aeroelastic instability can have an impact on the correct operation of the compressor. LÄS MER
2. New Measurement Methods For Ground Vibration Test
Master-uppsats, KTH/FlygdynamikSammanfattning : Flight-testing represents an important step of an airplane development. Every new or modified aircraft configuration is tested. Through set of tests, the quality and reliability of aircrafts are guaranteed. At Dassault Aviation, the flight test Directorate responsible for carrying out flight tests is located at Istres, in South of France. LÄS MER
3. Numerical analysis of aerodynamic damping in a transonic compressor
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Aeromechanics is one of the main limitations for more efficient, lighter, cheaper and reliable turbomachines, such as steam or gas turbines, as well as compressors and fans. In fact, aircraft engines designed in the last few years feature more slender, thinner and more highly loaded blades, but this trend gives rise to increased sensitivity for vibrations induced by the fluid and result in increasing challenges regarding structural integrity of the engine.

4. Produktionsoptimering av Fladder-avgradningssystem : Framtagning av layout för materialhanteringen runt Fladder-avgradningssystem
Kandidat-uppsats, Mittuniversitetet/Avdelningen för kvalitets- och maskinteknikSammanfattning : Detta examensarbete genomfördes för att undersöka hur materialhanteringen runt avgradningssystemet Fladder kan utvecklas och automatiseras. Behovet uppkom av dagens manuella hantering som är ineffektiv och tidskrävande och behöver därmed optimeras. LÄS MER
5. Transonic Flutter for aGeneric Fighter Configuration
Master-uppsats, KTH/FlygdynamikSammanfattning : A hazardous and not fully understood aeroelastic phenomenon is the transonic dip,the decrease in flutter dynamic pressure that occurs for most aircraft configurationsin transonic flows. The difficulty of predicting this phenomenon forces aircraft manufacturersto run long and costly flight test campaigns to demonstrate flutter-free behaviourof their aircraft at transonic Mach numbers.
