Definitions

  • the drogue parachute 47 when it deploys acts upon the carrier tether 48 to remove the main parachute carrier 50, which contains the main parachute 51 (inside), from within the payload apparatus 43.
  • the carrier 50 and main parachute are attached by a tether arrangement 49 to the parachute delay device 44 retained within the apparatus 43.
  • the drogue parachute 47 acts upon the carrier tether 48, which in turn acts upon the main carrier 50, via the attachment means 58 and concomitantly applies tension to the activator tether 56.
  • the activator tether 56 in this arrangement is already under tension compared to the carrier tether 48, such that upon a selected force being applied the activator tether acts upon the activator 53 causing deactivation of the engagement device 60, thereby releasing the carrier tether from the delay device 44.
  • the carrier tether remains operably linked by attachment means 58 to the main parachute carrier 58, and as the drogue parachute 47 applies further tension it removes the carrier 50 from around the main parachute 51 encased therein.
  • the main parachute 51 remains tethered by payload tether 57 to the delay device 44.
  • Figure 7 shows the controlled descent 70 of the illumination payload apparatus 71, under the control of the main parachute 74.
  • the device during its descent illuminates 72 the target area of interest, whilst ensuring that the payload apparatus 71 remains intact and under the control of the main parachute, such that it mitigates against collateral damage.
