Technology needs for high speed rotorcraft (3) [PDF]

The spectrum of vertical takeoff and landing (VTOL) type aircraft is examined to determine which aircraft are most likely to achieve high subsonic cruise speeds and have hover qualities similar to a helicopter.

Virtual Full Scale Static Test of a Civil Tilt Rotor Composite Wing in Non-Linear Regime

Aerospace
This study addresses the crucial role of post-buckling behavior analysis in the structural design of composite aeronautical structures. Traditional engineering practices tend to result in oversized composite components, increasing structural weight. EASA

Detailed analysis and test correlation of a stiffened composite wing panel [PDF]

Nonlinear finite element analysis techniques are evaluated by applying them to a realistic aircraft structural component. A wing panel from the V-22 tiltrotor aircraft is chosen because it is a typical modern aircraft structural component for which there

Integration of Rotor Aerodynamic Optimization with the Conceptual Design of a Large Civil Tiltrotor [PDF]

, 2010
Coupling of aeromechanics analysis with vehicle sizing is demonstrated with the CAMRAD II aeromechanics code and NDARC sizing code. The example is optimization of cruise tip speed with rotor/wing interference for the Large Civil Tiltrotor (LCTR2) concept
