Definition. Wind shear refers to the variation of wind over either horizontal or vertical distances. Airplane pilots generally regard significant wind shear to be a horizontal change in airspeed of 30 knots (15 m/s) for light aircraft, and near 45 knots (23 m/s) for airliners at flight altitude. Vertical speed changes greater than knots ( m/s) also qualify as significant wind shear for. Experimental and analytical study of the longitudinal aerodynamic characteristics of analytically and empirically designed Strake-wing configurations at subcritical speeds . A fixed-base simulation study has been made to evaluate the use of decoupled longitudinal controls during the approach and landing of a typical twin-engine jet transport in the presence of wind shear. employed all six rigid-body degrees of freedan.

analytical models. An analytical model should be capable of closely describing both the hysteretic behavior of each structural member and the interaction of connected members. Nevertheless, the analytical model should be relatively simple so that the analysis can be performed with reasonable computational effort. This last requirement is. ANALYSIS AND PREDICTION OF LONGITUDINAL STABILITY OF AIRPLANES By R. R. GILRUTHand M. D. WHITE SUMMARY An analysis has been made of the longitudinal stability characteristics of 15 airplanes as determined in flight. In the correlation oJ satisfactory and unsatisJactory char-acteristies with determined values, the derivative dSJdaCited by: 6. The differential element in Fig. 2 shows the in-plane shear stresses acting on the masonry (τ xy m) and FRP (τ xy f) as well as the two components of the epoxy shear stress (τ zx e, τ zy e).The model assumes that: (1) forces are transferred from masonry wall to FRP through shear only; (2) epoxy carry out only surface stresses; (3) both masonry and FRP layer carry only in-plane Cited by: The in-plane and out-of-plane responses of a curved floating bridge that is vertically supported by pontoons and laterally held by shore abutments at two ends are studied analytically. The in-plane solution is derived based on strain compatibility. An Euler curved beam model is used to develop the solution to the out-of-plane response of the Author: B. K. Lim, J. Dai, K. K. Ang, G.
