What happens when a helicopter 'wants to fly but does not fly'?

Destructive testing is a very important step in the development of an aircraft, similar to a car crash test. The objective of the demolition test is to determine the durability of the airframe in all operating conditions. As in the video below, we can see the Chinook CH-47 transport helicopter destroying itself in the harshest test:

The CH-47 Chinook is tied to the ground while both routers are running at full power. After all, the airframe was torn apart by the unbearable force of two forces, including the rotor's lifting force and the fixed force of the fixed system.

NASA has also experimented with the fallen Chinook from decades ago. In this test, the figures are also used to assess injury and survival if crew or soldiers on a Chinook encounter the same situation.

Throughout the tests, Chinook remained the most useful, mobile and reliable transport helicopter in more than 50 years. In fact, Chinook is still being manufactured and upgraded by the United States military and the aircraft will still serve in the military for many decades to come. By 2060, Chinook will be 100 years old.

Chinook or CH-47 Chinook is a Boeing product. This two rotor transport helicopter was developed in the late 1950s and made its first flight in September 1961. Chinook's main role was to transport troops, artillery and cargo. on the battlefield.

Chinook is one of the strongest shipping helicopters ever built.

Chinook is one of the strongest shipping helicopters ever built. With two 4757-horsepower Lycoming T55-GA-714A turbine engines, Chinook can reach speeds of up to 170 knots (315km / h). This engine also allows Chinook to carry many cargo and troops in up to 12 tons.

Currently, Chinook is being manufactured by Boeing Rotorcraft Systems with many military variants such as CH-47A / B / C / D / E / F / J, ACH-47A, MH-47D / E / G, HH-47. and civil versions used for commercial, multi-purpose and rescue purposes.
