Turbulent Wind and Its Effect on Flight

Abstract

= components of (W— WA) in FB or FA = components of Wm FE = velocity of airplane mass centre relative toFA = reference steady value of V = local velocity of the air relative to the Earth = mean value of W, velocity of frame FA = state vector = dX/du, etc., classical stability derivatives = wavelength, 27T/Q, = rms value of stochastic variable indicated by subscript = vector separating two points in FA = angular velocity of airplane relative to FE = local angular velocity of air relative to E = wave number vector in FA = matrix of three-dimensional spectrum functions = matrix of two-dimensional spectrum functions = matrix of one-dimensional spectrum functions = Laplace transform = transpose of matrix = ensemble average = complex conjugate Reference Frames FE:(xE,yE,zE)
