Unit Cost Development: $237 million (2007) Features:
The C-17 incorporates many of the military jet transport standards — a high-set wing (swept 25 degrees), T-tail, rear cargo-loading assembly and heavy-duty retractable landing gear with fuselage blister fairings. The aircraft also features a state-of-the-art "glass cockpit" (with four multi-function displays and a HUD for each pilot), a GEC fly-by-wire control system (featuring a stick rather than the conventional yoke
), four high-performance turbofan engines, an advanced supercritical wing section, winglets, and a "blown-flap" system. The aircraft is operated by a crew of three (pilot, co-pilot and loadmaster).
With a payload of 160,000 pounds, the C-17 can take off from a 7,600-foot airfield, fly 2,400 nautical miles, land on a small austere airfield in 3,000 feet or less. It can be refueled in flight
.* Cargo Compartment - Capacity:
18 fully-loaded 463L-type cargo pallets (88" x 108" @ 10,000 pound (4,536kg) capacity); up to 40 containers for Container Delivery System (CDS) airdrops; 102 troops; 48 litter and 54 ambulatory patients and attendants; three AH-64A Apache helicopters; one main battle tank; three Bradley armored vehicles.
Able to accommodate nearly 100 percent more cargo volume than the C-141B Starlifter, the C-17 can carry virtually all of the Army's air-transportable, outsized combat equipment. It is also able to airdrop paratroopers and cargo. All cargo is loaded through a large ramp/door assembly in the rear of the aircraft.* Engines:
The C-17 is powered by four fully-reversible Pratt & Whitney PW2040 series turbofans, designated as F117-PW-100 by the Air Force. Each engine is rated at 40,440 pounds (180kN) of thrust and employ thrust reversers that direct the flow of air upward and forward to avoid ingestion of dust and debris.* Supercritical Wing:
Like other military transports, the C-17 uses a "supercritical" wing. These are advanced airfoil designs that enhance the range, cruising speed, and fuel efficiency of jet aircraft by producing weaker shock waves that create less drag and permit high efficiency.* Winglets:
In the mid-1970s, the NASA-Langley Research Center developed the winglet concept through wind tunnel research. Winglets are small, wing-like vertical surfaces at each wingtip of an aircraft that enable the airplane to fly with greater efficiency. They curve flow at the wingtip to produce a forward force on the airplane, similar to the sail on a sail boat. Each C-17 winglet spans 9 feet, 4 inches.* Powered Lift & STOL Capability:
A key element of the C-17 is the special flap system, first developed by a team of researchers at NASA-Langley in the mid-1950s and later demonstrated on the YC-15 prototype. The externally "blown-flap" or "powered-lift" system enables the aircraft to make slow, steep approaches with heavy cargo loads. With this powered-lift system, the engine exhaust flow is directed below and through slotted flaps to produce additional lifting force and allow steeper landing descents.
Short TakeOff and Landing (STOL) capability is achieved when the trailing-edge flaps are extended into the exhaust flow from the engines during takeoffs and landings. The engine exhaust is deflected downward by the slotted-flaps to augment the wing lift. This allows aircraft with "blown flaps" to operate at roughly twice the lift coefficient of that of conventional jet transport aircraft.
The C-17 can operate on small, austere airfields with runways as short as 3,000 feet (914m) and as narrow as 90 feet (27.4m) wide, and can complete a 180-degree three-point "star" turn within 80 feet (24.4m). Also, when fully loaded, the aircraft is capable of backing up a 2 percent gradient slope using the directed flow thrust reversers.* Composite Materials:
Sixteen-thousand pounds of composite materials have been applied to the C-17. Several of the major control surface and secondary structu
