Available in PDF, EPUB and Kindle. Book excerpt: It is well known that wings with supercritical airfoils generally have lower transonic flutter speeds than similar wings with conventional airfoils and that small increases in angle of attack from zero and the accompanying static aeroelastic deformations have further detrimental effects on transonic flutter. This paper presents results of an effort to calculate the effects of angle of attack and the associated aeroelastic deformation on the flutter of a highly swept supercritical wing (TF-8A) by use of modified strip analysis. The spanwise distributions of steady-state section life-curve slope and aerodynamic calculations for as input for these calculations were obtained from static aeroelastic calculations for the wing by use of hte FL022 transonic code and an assumed dynamic pressure. The process is iterative so that flutter can be obtained at the same dynamic pressure as that used to calculate the statically deformed shape and loading about which the flutter oscillation occurs (matched conditions). Investigation results show that the unconventional backward turn of the transonic dip in the experimental flutter boundary for angles of attack greater than zero is caused by variations in mass ratio and not by static aeroelastic deformation, although inclusion of the latter appears to be required for quantitative accuracy in the calculations. For the very high subsonic Mach numbers of this investigation, quantitative accuracy will also require inclusion of viscous effects on shock strength and location.

This book was released on 1987 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern high performance aircraft designs tend to employ very thin airfoils having a degree and a distribution of stiffness far from the ideal; in consequence, there is a loss of control effectiveness and maneuverability. Moreover, the introduction of the highly forward-swept-wing planform poses a static aeroelastic effect of fundamental importance; these effects are felt at model as well as at full scale. This meeting was organized not only to review instances of these problems but to see how successfully modern tools for structural and aeroelastic analysis can be applied. The individual papers of the meeting cover many aspects of static aeroelasticity not only for military aircraft but also for modern transport aircraft. The various papers also address problems and recent progress in wind tunnel model testing, in particular measurement of static deformations on wind tunnel models.

Book Synopsis Supercritical Wing Flutter by : J. A. McGrew

Book excerpt: Transonic methods for correcting subsonic oscillatory aerodynamic influence coefficients (AIC's) based on the Doublet Lattice Method for use in flutter and dynamic response analyses of supercritical wings are developed and applied to a TF-8A flutter model and the YC-15II prototype aircraft. The effects of static aeroelasticity are included and evaluated. Reynolds number effects on test results are discussed. Correlation of improved methods showed good agreement with test results. For the two applications included, the steady corrections dominated the unsteady corrections. In the process of developing transonic corrections a new transonic lifting surface theory (currently two-dimensional) is presented, explored and correlated using the NLR 7301 airfoil. The effects of shock wave motion are included in the theory. (Author).
