Definitions

  • the disclosure of this invention pertains to a jet nozzle for jet propulsion engines, the nozzle having a centre body provided with aps movable to ⁇ divert the tlow of the gases.
  • Each tlap is supported on the centre body by a first and a second link, the irst link engaging the ap at 3 Claims stream ends thereof and being adapted to move the np away from a stowed position on the body, the second link being adapted to pivot the flap about said point into an obliquely rearward position for thrust-spoiling or an obliquely forward position for thrust-reversing.
  • a jet nozzle comprising a centre body and flow-diverting tiaps pivoted thereto, characterthe ap into an obliquely rearward or thrust-spoiling posithrust-reversing the large range of pivotal movement which is required if the flap is pivoted about one or other of its ends.
  • a jet nozzle comprising a centre body and flow-diverting tiaps pivoted thereto, characterthe ap into an obliquely rearward or thrust-spoiling posithrust-reversing the large range of pivotal movement which is required if the flap is pivoted about one or other of its ends.
  • FIGS. 1, 2 and 3 are sectional elevations of the nozzle and show the nozzle in first, second and third operational positions, respectively.
  • FIG. 4 is a perspective view of the nozzle.
  • connection between the flap and the pivot 30 is the ilap in a. position parallel to thelink 36 as if the flap were a part of that link.
  • the links 36, 26 cooperate to retain the pivot 27 in the FIG. 2 position while the motor 33 causes the movement of the ap between the second and third positions and retains lthe ap in either of those positions.
