Tie-Down Trials Involving a Sikorsky S-70B-2 Helicopter,

Abstract

Two tie-down trials involving a Sikorsky S-70B-2 helicopter are outlined. The first was land-based and utilized a hydraulic tilt table. The second took place on board an FFG-7 frigate. The trials are part of a DSTO investigation aimed at improving the tiedown procedures of S-70B-2 helicopters when operating from ships. A preliminary analysis of the data is presented and indicates that the type of lashing used to secure the helicopter can have a significant effect on the loads transmitted to the fuselage as well as affecting the relative motion of the aircraft. The effect of aircraft brakes on or off was examined and found to result in noticeable differences to the aircraft behaviour. During the ship trial, one type of tie-down lashing was observed to suffer from significant slippage through its locking mechanism.
