Platform Stabilization and Capture Systems

We produce advanced structural components for international navies and aircraft carriers that enable the safe landing and stabilization of aircraft in heavy sea conditions.

Our Related Defense Solutions

Aircraft Fixing Sockets (Aircraft Tie-Down Points)

These are the deck fixings we produced for the UK Navy's massive Queen Elizabeth Class Aircraft Carriers, as part of the partnership between BAE Systems, Curtiss-Wright and Indal Technologies. In this context, we successfully completed and shipped high-precision machining, hardness tests and special navy coatings of approximately 9000 critical structural fixing sockets over 18 months.

Solved Problems and Challenges

The tie-down points, which prevent airplanes and helicopters standing on the flight deck from sliding on the deck during a storm, are exposed to enormous tensile and shear stresses created by wave swaying. The material is intended to have impact strength at military standards, to withstand storms without breaking or dislodging, and to have high resistance to extreme marine corrosion.

Theoretical Background and Study

The design of our lashing sockets involves modeling the dynamic forces that aircraft lashing chains will apply to the socket star locks during a storm. With the help of Finite Element Analysis (FEA), the yield limit and fatigue life of the material are simulated and wall thicknesses and alloy ratios are optimized at the highest stress points. In manufacturing, forged steel raw material is used to ensure that there are no micropores in the internal structure of the material and it is verified by non-destructive tests. Additionally, by using Zinc-Nickel (Zn-Ni) alloy coating techniques, the salt spray test resistance of the parts is increased to over 1000 hours.

ASIST Helicopter Capture System Tension Control & Gripper Set

It is the sub-product group we developed for the ASIST (Aircraft Ship Integrated Secure and Traverse) system, which allows helicopters in the inventory of various international navies to be safely connected to the ship. We produce mechanical gripper equipment that grips the skids of the helicopter at the time of landing, and Tension Controller Unit parts that automatically compensate the chain tension according to the cradle movement created by the waves.

Solved Problems and Challenges

Helicopters landing on a ship in stormy weather (Sea State 5 and 6) must be instantly and securely locked to the deck immediately after landing. In order to prevent the helicopter from sliding, injuring deck personnel, or colliding with other equipment, the catching claw moving on the rail mechanism on the deck momentarily grasps the helicopter skids and fixes the vehicle to the deck by tension control.

Theoretical Background and Study

In order to compensate for dynamic stresses caused by ship rolling, closed-loop load cell feedback active tension compensation and quick locking nail mechanisms are used. In this way, helicopter rope tension is kept under constant control.
