To verify the structural strength of the CH-53K heavy-lift
helicopter, Sikorsky Aircraft Corporation, a subsidiary of
United Technologies Corp
), has completed a series of initial tests required by the Naval
Air Systems Command.
As a part of a three-year program, Sikorsky has built a static
test airframe, which is used to determine the capacity of the
helicopter to handle the structural loads that will be imposed on
it in flight and its structural integrity to operate safely over
its entire flight envelope. The Static Test Article is housed in
a test facility at Sikorsky's manufacturing plant in Stratford.
It enables Sikorsky to replicate the stresses, strains and
aerodynamic forces that the CH-53K helicopter will likely
experience during its flight. With this test, Sikorsky can
measure the airworthiness and crash worthiness while verifying
safety margins for all expected operational conditions.
Till date, Sikorsky has completed a total of six test conditions
on the Static Test Article. Sikorsky will continue to test the
structural integrity of the CH-53K Static Test Article for
another two years. The effective testing and validation is a
highly collaborative process to asses a helicopter's performance
and ensure that it meets the highest quality and safety
standards. These evaluations include additional checks to see how
an aircraft behaves with normal and exceptional loads.
