Abstract

Jet propulsion nozzle comprises a pair of mutually confronting side walls 11, a pair of mutually confronting first panels 14 extending transversely between the walls and being supported thereon for pivotal movement about a first axis 18. A pair of mutually confronting second panels 20 situated downstream of the first panels are pivotally supported on the respective first panels by pivots 21. Actuators 19,24 are adapted to pivot the panels 14,20 so that the panels can be moved between a convergent position (as shown) and a convergent-divergent position. Further, the second panels can be pivoted into a position in which they divert the flow obliquely away from the normal flow axis 15 of the nozzle, and the first panels can be pivoted into a position in which they reverse the flow through openings 34 normally closed by these panels.
