Close-up super-transport aircraft C-17 Globemaster III carrying President Trump's Marine One helicopter

Close-up super-transport aircraft C-17 Globemaster III carrying President Trump's Marine One helicopter
In order to serve US President Donald Trump during the APEC Summit in 2017, C-17 Globemaster III transport planes are still busy transporting tons of specialized goods, security equipment such as armored vehicles. Cadillac One and the Marine One helicopter are ready for the activities of the White House boss in Da Nang in the coming days. I had the opportunity to climb, photograph, play with the C-17 Globemaster III at the Singapore Air Show more than 3 years ago and invite you to view more details about this super transport plane.

C-17 is a large military transport aircraft developed for the United States Air Force. It was developed from the 1980s to the early 1990s by McDonnell Douglas. The name C-17 was inherited from two versions of Douglas C-74 Globemaster and Douglas C-124 Globemaster II. In the early 1990s, McDonnell Douglas merged with Boeing and continued to develop and produce the C-17 Globemaster III.

The C-17 Globemaster III has four turbofan turbojet engines that can transport large quantities of cargo and fly across the continent without refueling. The aircraft was developed to provide combat equipment and forces directly to the battlefield. The aircraft can unload at landing or in the air (drop the motor vehicle from the air that you see in the film?), And can perform tasks such as medical evacuation and missions. especially. With a cargo width of 5.5 m and a maximum height of 4.6 m, Globemaster III can accommodate 1 M1 tank or 3 IAV Strykers armored vehicles or 6 ASV M1117 vehicles.

C-17 Globemaster III has a body length of 53 m, a wingspan of 51.75 m. The wing of the aircraft is supercritical design with winglet wing tips that help reduce traction, increase fuel efficiency and flight range, external rear wing system, the back wings direct control of lift and the system. The high impact landing gear makes it possible for the aircraft to operate on standard or self-made runways. Each C-17 engine is also equipped with a forward / reverse thrust reversing system to help the aircraft stop faster when landing and reduce the impact of dust, debris and noise on operational personnel. on the ground.

The cargo compartment door, cargo step design and internal anchoring system can be operated with only one handling specialist and allow the equipment to be dismantled immediately without the need for specialized equipment. .

The cockpit of the C-17 is also upgraded with CRT monitors to increase reliability and reduce complexity. The built-in Test Status Diagnostics System (BIT) also helps reduce error checking and maintenance time.

The C-17 Globemaster III is powered by four Pratt & Whitney F117-PW-100 engines, the commercial version PW2040 of this type of engine is currently used on the Boeing 757. Each engine produces 180 kN of thrust equivalent. 18.3 tons of force. The engines are suspended at the front mount and below the leading edge of the wing. As mentioned above, all engines have thrust reverser or thrust reverser built into the engine casing and can be activated on the fly. When thrust reverser is activated, the blades and throat are all redirected. Thrust is forward and backward through shutters to maximize reversal thrust. On the ground, a fully loaded C-17 can run back up a slope of 2% thanks to repulsive thrust. Thrust reverser will direct airflow from the engine to the front or back to avoid dusting or surrounding debris. Combined with the principle of lift, the reverse thrust allows the aircraft to land on short runways.

The lift system of C-17 Globemaster III is very unique, exploiting airflow from the engine to increase the lift. By directing airflow from the engine into the outer flaps behind the wing to increase lift, the C-17 can approach the runway at a very slow landing speed. Specifically, the aircraft can land with a total cargo of up to 72 tons on a runway of only 914 m long.

C-17 Globemaster III is operated with a crew of 3 including a captain, an assistant and a specialist in charge of cargo and load (loadmaster - she is right in the picture). C-17 Globemaster III performance parameters:

The C-17 Globemaster III is currently worth about $ 218 million in the US. By 2012, there were 250 C-17 Globemaster III shipped and is on the payroll of many countries such as the United States, Canada, India, Great Britain, UAE, Qatar and NATO.

Some pictures of C-17 Globemaster III:

This C-17 Globemaster III is nicknamed .... The spirit of Kamehameha, and not the ultimate of Songoku in the seven dragon balls, Kamehameha (Kalani Paiʻea Wohi o Kaleikini Kealiʻikui Kamehameha o ʻIolani i Kaiwikapu kauʻi Ka Liholiho Kūnuiākea) was the name of the first king of Hawaii 😁.

The cockpit is full of buttons, joysticks and screens.

With such a sophisticated control system, the C-17 Globemaster III does not need engineers like a three-man crew on many other large aircraft, only the captain and co-pilot are enough.

Inside the cargo area overlooking, the ceiling was nearly 5 m high.

Looking at the ceiling of the cargo compartment with dozens of cords and hydraulic hoses, it caters for fly-by-wire control and cargo handling systems.
