The subject of the present thesis is the numerical evaluation of take-off performance of an innovative aircraft configuration in the framework of the PARSIFAL project.
Specifically, the main objectives are the determination of the required take-off distance for a 300 seat Prandtlplane civil transport aircraft and the evaluation of its tail-clearance requirements.
In order to achieve the aforementioned objectives, a series of numerical simulations have been carried out in
MATLAB, based on a non linear dynamic model which describes in detail each segment of the take-off phase.
The aerodynamic effects due to the close proximity of the aircraft to the ground during take-off have been kept into account, and their influence on take-off performance is thoroughly discussed.
Subsequently, a method for the design of the rear fuselage in compliance of the tail-clearance requirements is presented, based on the data related to the aircraft dynamics obtained in the aforementioned take-off numerical simulations.
Finally, in order to highlight the advantages offered by a Prandtlplane configuration during take-off, a comparison is performed with the performance and tail-clearance requirements displayed by a reference conventional aircraft.
