Simulation of the Horizontal Tail Plane Stall of a Transport Aircraft

The present study aims at assessing the influence of the interference effects caused by the horizontal tail plane (HTP) and vertical tail plane (VTP) on the aerodynamic behaviour of a transport aircraft in high-lift configuration. This aspect is of particular interest close to aircraft stalling conditions. The present study therefore assesses the effects caused by the tail plane during onflow conditions that represent stall manoeuvres. In this regard numerical simulations at extreme points of flight envelopes are analysed, by considering effects of discretization, physical turbulence models and incidence stall settings
