Boeing CH-47 Chinook

History of the Boeing CH-47 Chinook

The Boeing Chinook family of mid-lift tandem rotor transport helicopters has been the mainstay support system of the U.S. Army (and other forces) for decades since its introduction in 1962. When hauling mid-range loads on the battlefield, rotor approach provides the necessary buoyancy characteristics - the ability to transport weapons, supplies, full combat readiness and other useful components to and from the point of operation.

Despite its origins in the 1960s, the CH-47 is still in service around the world and should continue to be one of the most versatile transport helicopters ever built - it's significant that the series won't be retired until 2060 at the earliest, while they will The be is said to be the U.S. military's first "100-year-old" aircraft.

The history of the CH-47 began in the mid-1950s, when the U.S. Army was trying to replace its inventory of Sikorsky CH-37 Mojave transport helicopters. Production of the system - which was unsuccessful due to operating costs, size and reliance on piston-driven engines - was limited to 154 units.

Service began in July 1956 and ended relatively quickly in the late 1960s. Turbine engines were soon introduced and replaced piston engines in helicopters with successful products such as the Bell UH-1 "Huey" medium lift transport helicopter, so a completely new medium lift system based on a more powerful and more powerful propulsion was not expected.

A small number of Chinooks were converted from existing C-type inventory to D-standard as "MH-47D" for special forces. The MH-47E is another special forces version - it is based on the E-type prototype released in the early 1990s and has a larger fuel reserve.

Production of this model reached 26 units. The later standard for special operations models became the MH-47G, following the form and function of the E model, but with state-of-the-art systems, including a full "glass" cockpit.

The Dutch government purchased ex-Canadian CH-147s and used them under the guise of an improved D-Standard. This gave Canadians the freedom to buy the D model in 2008. The Japanese joined foreign operators with locally licensed "CH-47J" Chinooks.

The J model is equipped with different avionics and engines than the US-born model. The successor model is CH-47JA. Both are built under the Kawasaki brand label.

Many export versions are based on the structure of the CH-47D model.

The CH-47F is the latest Chinook product, first flying in 2001. The offering includes newer upgraded engines, each rated at 4,868 hp for improved field performance, and the hull is based on milled construction for improved robustness. The cockpit fully supports the modern digital avionics suite.

Delivery of this variant started in 2006.

As the first export user, the U.S. Army signed a contract with the Netherlands for 191 F-Types and ordered 6 of them. Other operators have become Australia and the UK. Despite its novelty, the CH-47F has been designated for upgrades through the "Block 2" program and the "Block 3" proposal, aimed at making this powerful system a viable battlefield component by the mid-2000s. The Block 2 upgrade will restore the F-model's transport capabilities to A-model levels, while the Block 3 is a redesign in line with the Army's Future Affordable Turbine Engine (FATE) program, which is in line with other helicopter products in inventory, including Boeing AH-64 "Apache" attack helicopter).

The U.S. Army has been working on a program to replace its D-model lineup with an updated F-model, and the transition is expected to be completed in 2019.

Following certification for civil airspace operations, the Chinook appeared in a number of civilian market products - through the Type 234 and Type 414 variants.

Sixteen countries have participated in the history of CH-47, with more than 1,200 built since 1962. Some of the Chinook's most recent combat operations have focused on coalition interventions in Afghanistan and Iraq, resulting in some airframe losses and one fatality.

Due to the Chinook's ability to carry a large number of people, the aircraft can cause a large number of casualties when it is shot down or crashes due to an accident/human error. In an incident near Kabul, Afghanistan, in 2005, a special forces unit aboard a Chinook aircraft was shot down by enemy forces, killing all on board.
