“…Such aeroelastic tailoring of the structure has been practiced for several years for static aeroelastic loads and is an established capability of several structural optimization codes such as NASTRAN 4 and the CASSIDIAN in-house code LAGRANGE. 5 With the finely adjustable stiffness properties of composite materials, the potential for performance improvements through aeroelastic tailoring are increased even further.…”

Airframe design as an essential part of aircraft design is inherently multidisciplinary. The complexity of the structural design task stems not only from the challenges in each of the involved disciplines -loads, aerodynamics, stress, dynamics, mass, aeroelastics, design and manufacturing but also from the complex and mutual influence of these disciplines. This paper describes a multidisciplinary airframe design process, particularly regarding automating sizing and loads loops. On the one hand the huge complexity, the scientific challenges and, on the other hand, the benefits expected are discussed.

“…Some optimisation methods have an excellent convergence for a single discipline but the ability becomes limited if more disciplines are involved. The optimisation software LAGRANGE, see [5], considers for each element and load case automatically one stress-or strain constraint. This is reasonable because all load carrying structure elements have to be verified for strength.…”

“…The aeroelastic input for optimisation software LAGRANGE [5,6] requires aileron and roll damping efficiency factor constraints based on the selected design roll rate. First we have to examine the rigid roll rates of the different wing aspect ratios.…”
