Unit Maintenance Aerial Recovery Kit (UMARK).
Abstract
This report describes the activities performed under Contracts DAAJ02-92-C-0048 and DAAJ02-97-M-0004, to produce prototype UMARK kits. The objective of the program was to develop a means of aerial recovery of inoperative and lightly and heavily damaged helicopters using medium-lift and heavy-lift helicopters as the recovery vehicles. The UNMARK is the result of this work. UMARK can recover the following helicopters (and can easily accommodate others): AH-64, AH-64 Longbow, CH-47, UH-60, AH-1 and UH-1 (all Army models), OH-58 (A/C and D), and RAH-66 Comanche. UMARK is lightweight, compact and can fit in a HMMWV, CUCV, van, pickup track, or helicopter. Three people can fully rig any helicopter in 15 minutes or less. It is adaptable to future requirements without extensive modifications or additions to the Kit. Kit complexity is minimized to reduce training, reduce rigging time, and heighten safety. UMARK is a major improvement over previous methods of aerial recovery. This report discusses all tasks performed under these contracts, including: Design and analysis, prototype fabrication, limit and ultimate strength testing, ground testing to develop and verify rigging procedures, and flight testing to fine-tune rigging procedures and verify Kit effectiveness.
