1. 1. Computational Analysis of Spray Deflector Designs

   University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Author : Osman Gyokhan Ali; [2023]
   Keywords : Planing Hulls; Spray Deflector; Hull Modification; Computational fluid dynamics CFD ; resistance; trim angle; heave; CD-adapco Star CCM ; Numerical Ventilation; Phase Replacement; Modified HRIC Scheme; Volume Fraction Source Term; Reynolds averaged Navier-Stokes RANS ; Volume of Fluid VOF ; SST K-Omega Turbulence Modelling; Höghastighetshantverk; modelldesign; spraydeflektor;

   Abstract : Planing hull is a common hull design concept which decreases the resistance while speed is increasing for a specific speed range. It is also suitable for hull modifications to achieve higher efficiency. Spray deflector is a promising hull modification which offers extra resistance decreasing and less vertical acceleration for planing hulls. READ MORE

3. 2. Model Design for Further Spray Deflector investigation

   University essay from KTH/Marina system

   Author : Xinguo Wang; [2021]
   Keywords : High-Speed Craft; Model Design; Spray Deflector; Höghastighetshantverk; modelldesign; spraydeflektor;

   Abstract : Planing hull is one solution to break the speed barrier of conventional hull, but as the boat reaches a high speed, massive whisker spray will be developed and attached to the hull, which causes a notable resistance increase. A Swedish company Peterstep invented an innovative spray deflector that can deflect the spray backwards and harvest kinetic energy from the spray. READ MORE

4. 3. Investigating the aerodynamic performance of an UAV

   University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

   Author : Bala Murali Krishna Gummadi; Rahul Rajan Sourirajan; [2021]
   Keywords : Computational Fluid Dynamics; Aerodynamics; Flight Stability;

   Abstract : The aerodynamic performance of any airborne vehicle is an important characteristic to be considered during the concept development process. Lift and drag forces are the two most important aspects of aerodynamics that dictates vehicle efficiency. READ MORE

5. 4. Experimental study on stepped spray deflectors for planning hull

   University essay from KTH/Marina system

   Author : Luca Castaldi; [2020]
   Keywords : ;

   Abstract : Planning vessels can reach high operational speeds thanks to their hull design. Some hull forms will develop large volumes of spray attached to the hull surface. The whisker spray is a thin layer consisting in droplets of water which can ac-count for a large proportion of the total resistance. READ MORE

6. 5. Design of a drone system for maritime search and rescue missions

   University essay from KTH/Flygdynamik

   Author : Emil Pettersson; [2020]
   Keywords : Sea Rescue; Drone; Flying Wing; Blended Wing Body; SAR; Tailless; BWB; XFLR5; Search and Rescue; Drönare; Flygande Vinge; Sjöräddning; Eftersök; XFLR5;

   Abstract : The work summarized in this report aims to investigate how a drone airplane design can be optimized to create a safer and more efficient sea rescue by providing staff with an early picture, performing search missions and aiding communication through visual contact. A flying wing is in theory one of the most efficient designs for a fixed wing aircraft, at the same time as it also offers high structural efficiency for its given size. READ MORE
