1. 1. Electrical Propulsion System Design of a Blended Wing Body UAV

   Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

   Författare :Kevin Azad; Felix Fungula; [2022]
   Nyckelord :Aerospace; Aviation; Blended Wing Body; Electrical; Green Raven; Propeller; Propulsion; UAV;

   Sammanfattning : The conventional tube-and-wing aircraft has been around since the 1950s, with little to no innovative progress being made towards redesigning the conventional aircraft. The blended wing body (BWB) shape fuses the wing of the aircraft with the fuselage increasing structural strength while also increasing potential surface area to create lift, making it more efficient than conventional wing shapes.

3. 2. Development of a System Identification Tool for Subscale Flight Testing

   Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

   Författare :Adrian Arustei; [2019]
   Nyckelord :GFF; Generic Future Fighter; system identification; orthogonal function modeling; equation error method; output error method; aerodynamic derivatives; flight dynamics; flight testing;

   Sammanfattning : Aircraft system identification has been widely used to this day in applications like control law design, building simulators or extending flight envelopes. It can also be utilized for determining flight-mechanical characteristics in the preliminary design phase of a flight vehicle. LÄS MER

4. 3. Design and manufacturing of a thrust measurement system for a micro jet engine : Enabling in-flight drag estimation for subscale aircraft testing

   Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

   Författare :Anna Martinez; [2018]
   Nyckelord :thrust measurement; drag estimation; subscale aircraft; in-flight measurements;

   Sammanfattning : Good estimation of aerodynamic coefficients is of fundamental importance in the design and development process of an aircraft. Generally, these parameters are obtained using analytical, numerical and experimental methods, which are sometimes either inaccurate or very expensive. LÄS MER

5. 4. Simulation Model Development of a Subscale Fighter Demonstrator : Aerodynamic Database Generation and Propulsion Modeling

   Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

   Författare :Carry Prameswari; [2017]
   Nyckelord :;

   Sammanfattning : The main objective of this thesis was to improve the simulation model of a subscale fighter demonstratorthat had been developed previously. In order to give a reliable result, the simulation model should be modeled correctly and employ accurate input. LÄS MER

7. 5. Design and Testing of a Flight Control System for Unstable Subscale Aircraft

   Master-uppsats, Linköpings universitet/Fluida och mekatroniska system; Linköpings universitet/Tekniska fakulteten

   Författare :Alejandro Sobron; [2015]
   Nyckelord :aircraft design; systems integration; subscale flight testing; avionics; flight control system; remotely piloted aircraft;

   Sammanfattning : The primary objective of this thesis was to study, implement, and test low-cost electronic flight control systems (FCS) in remotely piloted subscale research aircraft with relaxed static longitudinal stability. Even though this implementation was carried out in small, simplified test-bed aircraft, it was designed with the aim of being installed later in more complex demonstrator aircraft such as the Generic Future Fighter concept demonstrator project.
