The lift slope for low aspect ratio straight wings in compressible flow, often denoted as , is a parameter that characterizes the rate of change of the lift coefficient () with respect to the angle of attack () under compressible flow conditions. It quantifies how the lift generated by the wing changes as the angle of attack is varied while accounting for compressibility effects. The specific formula for for low aspect ratio wings in compressible flow can be more complex and dependent on the wing’s geometry, airfoil shape, and other factors. It may not have a simple analytical expression like the one for high aspect ratio wings.
