Abstract

A recovery device for use from the cargo door of a helicopter hovering over vehicle to be recovered and including a telescoping pole with an upper end secured to the helicopter floor and a lower end defining a hoop which can be manipulated around the weapon or target into a first position for securing a first noose to a first portion of the vehicle to be recovered. The snare pole is then shifted to a second position where a second noose is tightened around a second portion of the vehicle. After the nooses have been positioned about the vehicle, the crewman aboard the helicopter pulls the retainer lanyard joined to the retaining pins. This operation releases the snare pole from the helicopter. The inner pole telescopes within the outer pole, and the vehicle is held directly beneath the helicopter by the cargo hook. The pilot can then fly the helicopter upwardly to carry the vehicle clear of the water.

Dependent claims

A vehicle recovery device for use by a crewman in a hovering helicopter equipped with a cargo hook, said device comprising:

an elongated pole, said pole having a hoop mounted at one end, and having an opposite end adapted to be manipulated from the helicopter so that the hoop can be moved over one end of the vehicle;
a first line having a noose releasably retained in said hoop and also adapted for manipulation from the helicopter to tighten the noose around a first portion of the vehicle;
and
a second line having a second noose also releasably retained on said hoop, said second line being supported by said pole independently of said first line whereby the pole can be relocated from a first position with said first noose tightened around a first portion of the weapon into a second position spaced from the first position so that the first and second nooses can be successively tightened around spaced first and second portions of the vehicle to facilitate raising the vehicle weapon from the sea in a controlled orientation determined by differential manipulation of said first and second lines from the helicopter.
