ImageToday’s service members rely heavily on air dropped military supplies. The Natick Soldier Research, Development and Engineering Center (NSRDEC) has developed the low cost ground release (LCGR) to address parachute payload delivery in military operations. The critical nature of air-dropped military supplies demands a high level of reliability because release failures can destroy or damage a payload, drag the payload to the wrong location, and lengthen the recovering ground personnel’s exposure to hostile combatant forces while freeing the cargo.

The LCGR can deliver payloads ranging from 150 – 2,200 pounds. The design is a load relaxation mechanism which relies on the drag of the parachute and weight of the load to maintain the connection between the payload and parachute. Upon impact with the ground, the suspension system is in a momentary “no load” condition, allowing the device to separate the connection between the payload and parachute. This device utilizes an assist spring to separate the two identical face plates, resulting in a separation of the parachute from the payload. The device is attached between the payload and parachute via soft loop connectors, and secured to the load via ¼” cotton webbing on the load side and either ¼” cotton webbing or ½” tubular nylon webbing tie on the parachute side, depending on the payload weight.

The LCGR may have broad ranging applications within allied military organizations, humanitarian relief efforts, and backcountry drops by organizations such as the US Forest Service or the Bureau of Land Management. Integration into commercially available payload parachutes may give the user more certainty of successful delivery over traditional payload parachutes.
