Development of an aeroelastic stability boundary for a rotor in autorotation [PDF]

, 2008
<p>For the present study, a mathematical model AMRA was created to simulate the aeroelastic behaviour of a rotor during autorotation. Our model: Aeroelastic Model of a Rotor in Autorotation (AMRA) captures transverse bending and teeter ...

Numerical Simulation of Folding Tail Aeroelasticity Based on the CFD/CSD Coupling Method

Vibration
This paper presents a CFD/CSD coupling method for aeroelastic simulation of folding tail morphing aircraft. The unsteady aerodynamic analysis is based on an in-house computational fluid dynamics (CFD) solver for the Euler equations, and emphasis is made ...

Effects of nonlinear aerodynamics and static aeroelasticity on mission performance calculations for a fighter aircraft [PDF]

During conceptual design studies of advanced aircraft, the usual practice is to use linear theory to calculate the aerodynamic characteristics of candidate rigid (nonflexible) geometric external shapes.

Assessment of the Fatigue Behavior of Wings with Distributed Propulsion

Engineering Proceedings
The integration of distributed electric propulsion into a wing significantly alters the dynamic behavior of the wing. Consequently, the loads on the wing structure in service, in particular upon transient gust and landing impact loads, change ...
