Research Institution
The Expeditionary Fighting Vehicle (EFV) has two external fuel tanks that have a total capacity of 238 gallons, and weigh nearly 500 lbs each. The US Marines seek to reduce the weight of each external tank by 40% to 310 lbs, while not compromising survivability or capacity. Self-sealing coating technologies such as polyurea are desired; however, the added weight of this feature may present an integration challenge. The competing requirements of ballistic protection, fuel containment, and vehicle weight present a significant engineering challenge in this application. Innovative solutions that balance these performance traits are required, particularly strategies to achieve compact, low surface area fuel tanks that enable the full thickness of a polyurea coating necessary for self-sealing.
