Pilot-ejection apparatus incorporating a stabilising drogue parachute as described in the parent Specification embodies a modified drogue release mechanism, shown assembled in Fig. 10, comprising two torque shafts 2, 9, one within the other and free to turn independently thereof, the shaft 2 having a member 3 holding the drogue shackle 15 in a portion 13 of the seat frame, locking means 7 alongside the member 3 for retaining it in operative position, the other shaft 9 having means 8 for retaining the locking means 7 in operative position. Members 5, 6 capable of limited angular movement relative to the shaft 2 are connected by rods 5a, 6a to the pilot's harness lock mechanism, and the ejection gun firing cable 17a is attached to a link 17 engaging the sear 19 of the ejection gun 19a, Fig. 7. In normal operation the cable 17a and link 17 are withdrawn to initiate firing of the gun 19a, and after the predetermined period the plunger of the time-delay mechanism 22 engages the lever 10 to rotate the inner shaft 9 and disengage the hooks 8 from the arms 7a of the locking members 7, thus allowing withdrawal of the drogue shackle 15. During such withdrawal, Fig. 12, the shackle rotates the holding member 3, such rotation being communicated by the shaft 2 to the members 5, 6 to operate the pilot's harness lock mechanism, thus releasing the seat and initiating opening of the pilot's main parachute. In the case of operation by the manual override mechanism, Fig. 13, the push rod 20 engages the lever 10 and rotates the holding member 3 to lift the drogue shackle 15 and thus disengage the firing link 17 from the sear 19. The members 5, 6 are also rotated to operate the rods 5a, 6a, and a lever 11 raises a spring housing 12 to release the drogue line 12b from the drogue gun piston 12a. In the event of consecutive failure of the drogue gun, time-delay device and manual over-ride, a spring-loaded plunger 33, Fig. 14 (not shown), may be released by the withdrawal of a locking pin 34 connected to the rip cord, and engage the lever 11 to operate the mechanism. Fig. 6 shows a modified time-delay mechanism and plunger rod, the static line 24 operating a sear rod 25 and catch 26 by which the escapement is released. At the end of the delay period a rack 28 is disengaged from a pinion 30 and the spring 27 forces the plunger 31 upwardly against the lever 10. The member 20b is connected to the manual over-ride control lever. Specifications 583,257, 630,748, [Group XXVIII], and 640,520 are referred to in the Provisional Specification.
