Aeroelastic tailoring of oscillating supersonic wing with external stores

This paper presents aeroelastic tailoring optimization of a swept back supersonic wing with external stores using composite structure material for the wing skin. The analysis has been conducted to calculate the flutter speeds at several altitudes ranging from a negative altitude of -7,943 ft until...
