The main objective of the proposed research project is the development of the FDM and flight simulation forx000D
Airvinci's rotorcraft. It consists of the three main components: The first component is the development of FDMx000D
for rotor motions. Wind tunnel and flight tests are beyond the scope of this project. For this reason, this projectx000D
will employ the numerical methods such as the blade-element formulation, Pitt-Peters dynamics inflow model,x000D
and powertrain model. These methods are generally utilized to develop the rotorcraft FDM. The blade-elementx000D
formulation subdivides each rotor into segments, and the local airspeed and angle of attack are determined forx000D
each element. Then these results are used to determine the aerodynamic forces of the main rotor. Thex000D
Pitt-Peters dynamic inflow model will determine the total airflow of the rotorcraft and the powertrain modelx000D
with engine dynamics model will determine the rotor rotational speed. The second component is thex000D
development of FDM for the fuselage and control surfaces. The rigid-body 6 Degree-of-Freedom (DOF)x000D
equations and aerodynamics models will be employed to develop the dynamic model of the fuselage andx000D
control surfaces. The Center of Gravity (CG) location will be derived from the geometry and materials.x000D
Aerodynamics forces and moments for the fuselage and control surfaces will be determined from numericalx000D
equations. The third component is the implementation of mathematical models of the rotorcraft into JSBSim.x000D
The FDM is then combined with FlightGear to develop the dedicated simulation of the Airvinci's rotorcraft andx000D
its performance over a range of environments. The development of visual simulation entails 3D models of thex000D
rotorcraft to be used with Blender (www.blender.org) which is an open source 3D modeling software. Blenderx000D
is compatible with FlightGear and it can import and export various types of 3D models. The developed FDMx000D
will be updated from the feedback of the flight test on the developed simulation.
