BAK-14 Retractable Hook-Cable Support System Cold-Weather Tests at Galena, Alaska
Abstract
The BAK-14 retractable hook-cable support system was designed for use with aircraft arresting systems on Air Force/Civil joint-use airfields. In the raised position, the BAK-14 supports the aircraft arresting-hook cable above the runway surface for engagement of arresting-hook-equipped aircraft; in the lowered position, the runway surface is clear and the BAK-14 offers no interference to the operation of lightweight civil aircraft. These tests were conducted to determine the effects of natural low-temperature conditions on the functional and dynamic operation of the BAK-14. The areas of special interest were the ability of the support block to withstand aircraft main-gear trample and arresting-hook impact, and the ability of the system to cycle 100 times. The system sustained negligible damage from F-4E aircraft tramples, but was inoperable as a result of the cumulative damage caused by six arrestments. Under low ambient temperatures (-15 F to -24 F), the supports were not pliable. All 14 blocks of the system were partially to fully separated from their bases. Support-block latch mechanisms were damaged. During the 100-cycle test, completed under -33 F to -36 F ambient temperatures, several support latch mechanisms malfunctioned and required adjustment. Test results indicated that the BAK-14 is not suitable for operation at low ambient temperatures.
