Studies of Store-Induced Limit-Cycle Oscillations Using a Model with Full System Nonlinearities

Effect of thrust on the aeroelastic instability of a composite swept wing with two engines in subsonic compressible flow

“…To this aim, a reference wing is considered as defined in Table 3, where the structural and geometrical properties of the wing are set to those of the heavy Goland wing (Beran et al, 2004). Then the variations of the aeroelastic instability speed and critical thrust versus a specified parameter of the wing are investigated while the other Table 1 Flutter analysis results of four wings from Barmby et al (1951 parameters are fixed.…”

Normal form representation of the aeroelastic response of the Goland wing

“…1. The geometric and physical properties of the aeroelastic system are similar to the ones considered by Beran et al [3] and are provided in Table 1. The wing is assumed to undergo bending around the x axis and twisting around the y axis.…”

“…In the subcritical type, a sudden jump to a large-amplitude LCO takes place at or below the flutter speed, depending on the initial conditions. Beran et al [3] examined the effect of aerodynamic, structural, and store model nonlinearities on LCOs for the Goland wing/store configuration. Vibration modes of a cantilever beam were employed and the Galerkin approach was used to discretize the coupled bendingtorsion system.…”

Aeroelastic energy harvesting: A review

“…Because of the presence of high angles of attack, they modeled the aerodynamic loads by using a quasi-steady approximation with a stall effect (Beran, Strganac, Kim, & Nichkawde, 2004;Gilliatt, Strganac, & Kurdila, 1998;Gilliatt, Strganac, & Kurdila, 2003), which are given by:…”
