초록
▼

An aircraft (10), in particular a trainer aircraft with improved aerodynamic performance, having a configuration able to keep a directional stability and a very good aerodynamic behaviour even at very high angles of attack, where, traditional configurations prove themselves inefficient. In particular, this configuration foresees a forebody (52) with variable section, optimised for high angle of attack flights, a LEX vortex control device (72) at least one diverterless air intake (46), and a wing profile (18, 20) optimised in order to reduce the buffet ef...

The invention claimed is: 1. Configuration of an aircraft (10) with improved aerodynamic performance, so as to maintain direction stability at mid/high angles of attack, said aircraft (10) having a fuselage (12) fitted with wings (18, 20) and leading edge extensions each leading edge extension ("LEX") having an area at least one air intake (46) and a fuselage forebody (52) with a tapering section, said aircraft (10) including a LEX vortex control device (72) shaped such as to make symmetrical the bursting of the vortex generated by a said LEX at mid/hig...
