c. Release. Cargo Parachute. M-1. The M-1 cargo parachute release consists of a arming wire lanyard (1), arming wire (2), parachute connectors (3), upper load suspension link (4), a timer delay assembly contained within the release body (5), and lower suspension links (6). A cargo parachute release separates medium (64-foot diam G-12D) or large (100-foot diam G-11A) cargo parachutes from an air dropped load upon ground contact. This prevents the dragging or overturning of the load by winds. The Release, Cargo Parachute, M-1 is designed for use in the airdrop of loads weighing from 200 to 15,000 pounds (90 to 6,800 kg). The M-1 release is capable of accommodating four G-11A or three G-12D cargo parachutes. The two lower suspension links connect to four airdrop platform suspension slings. Cargo parachutes are joined to the M-1 release by connectors that are held in place by a toggle mechanism. The parachutes separate when the release body tilts at a critical angle as the suspended load contacts the ground. The mechanical delay release timer prevents early separation. The timer is activated when the load parachute(s) begin to deploy, pulling on a nylon webbing lanyard (2) that is attached to an arming wire (4) installed in the release timer.

NOTE

The delay release timer, parachute release connector, arming wire, and arming wire lanyard are interchangeable for use between the M-1 and M-2 airdrop cargo parachute releases.

d. Release Cargo Parachute, M-2. The M-2 cargo parachute release is similar to the M-1 described in paragraph c., above. It also consists of a arming wire lanyard (1), arming wire (2), parachute connectors (3), upper load suspension link (4), a timer delay assembly contained within the release body (5), and lower suspension links (6). It is designed for use in the airdrop of loads ranging in weight from 6,000 to 35,000 pounds (2,700 to 15,900 kg), using G-11A cargo parachutes. Because it handles heavier loads, the M-2 release can accommodate three to eight G-11A cargo parachutes. The lower suspension links (4) are connected to four airdrop platform suspension slings.
