NICETRIP - Novel Innovative Competitive Effective Tilt Rotor Integrated Project

2006-2010

Contract Number 030944

6th FP European Research Project.

The research contribution from “Dipartimento di Scienze e Tecnologie Aerospaziali” (at that time Dipartimento di Ingegneria Aerospaziale) of “Politecnico di Milano” spans the entire project, from numerical analysis of aerodynamics, flight mechanics, aeroelasticity, structural dynamics, to wind-tunnel testing. MBDyn is used in the aeroservoelastic and structural dynamics analysis of up to the full-span tiltrotor.

POLIMI’s tasks involve:

• investigation of model nonlinearity issues in whirl-flutter stability and limit-cycle oscillations (LCO);
• aeroelastic stability of the rotor;
• preliminary aeroelastic sizing of the tail;
• overall aircraft aeroservoelasticity and structural dynamics.

The sizing of the tail is performed by Luca Cavagna and Giuseppe Quaranta using NeoCASS, a tool developed by POLIMI within the SimSAC project. Professor Sergio Ricci is POLIMI’s coordinator of SimSAC.

Points of contact were Professor Marco Borri (POLIMI coordinator); Dr. Pierangelo Masarati (responsible for dynamics related tasks) and Dr. Giuseppe Quaranta, for aeroservoelasticity and structural dynamics.
