Evaluation of Low-Modulus Nylon and Energy-Absorbing Stainless-Steel Deck Pendants Used with the E-28 Arresting-Gear System

Abstract

Stainless steel-nylon deck pendants as a means of reducing the dynamic arresting-hook loads which occur during arrestments of lightweight fighter aircraft are evaluated. In addition to pendant performance, simulated aircraft main-wheel-rim rollovers of the pendants were conducted to determine the extent of pendant damage incurred and various types of pendant-to-purchase- tape connecting hardware were evaluated. One hundred sixty-three arrestments were conducted ON-CENTER and 35 feet OFF-CENTER TO PORT AT ENGAGING SPEEDS RANGING FROM 114 TO 233 KNOTS. Twelve rollovers were conducted at a speed of approximately 100 knots. The arresting-hook loads obtained when using low- modulus nylon and energy- absorbing stainless-steel pendants were 35 and 25 percent lower, respectively, than those obtained when using the standard steel pendant. Based on these results, it is possible to increase the engaging-speed limit of lightweight fighter aircraft to 230 knots.
