Boeing 727
Illustrative image; it may differ from the actual aircraft.The Boeing 727 is an American narrow-body trijet that was developed and produced by Boeing Commercial Airplanes. After the heavier 707 quadjet was introduced in 1958, Boeing addressed the demand for shorter flight lengths from smaller airports. On December 5, 1960, the 727 was launched with 40 orders each from United Airlines and Eastern Air Lines. The first 727-100 rolled out on November 27, 1962, first flew on February 9, 1963, and entered service with Eastern on February 1, 1964. The only trijet aircraft to be produced by Boeing, the 727 is powered by three Pratt & Whitney JT8D low-bypass turbofans below a T-tail, one on each side of the rear fuselage and a center one fed through an S-duct below the tail. It shares its six-abreast upper fuselage cross-section and cockpit with the 707 that was also later used on the 737.

The story of the type
Development
The Boeing 727 design was a compromise among United Airlines, American Airlines, and Eastern Air Lines; each of the three had developed requirements for a jet airliner to serve smaller cities with shorter runways and fewer passengers. United Airlines requested a four-engine aircraft for its flights to high-altitude airports, especially its hub at Stapleton International Airport in Denver, Colorado. American Airlines, which was operating the four-engined Boeing 707 and Boeing 720, requested a twin-engined aircraft for efficiency. Eastern Airlines wanted a third engine for its overwater flights to the Caribbean, since at that time twin-engine commercial flights were limited by regulations to routes with 60-minute maximum flying time to an airport (see ETOPS). Eventually, the three airlines agreed on a trijet design for the new aircraft.
In 1959, Lord Douglas, chairman of British European Airways (BEA), suggested that Boeing and de Havilland Aircraft Company (later Hawker Siddeley) work together on their trijet designs, the 727 and D.H.121 Trident, respectively. The two designs had a similar layout, the 727 being slightly larger. At that time Boeing intended to use three Allison AR963 turbofan engines, license-built versions of the Rolls-Royce RB163 Spey used by the Trident. Boeing and de Havilland each sent engineers to the other company's locations to evaluate each other's designs, but Boeing eventually decided against the joint venture. De Havilland had wanted Boeing to license-build the D.H.121, while Boeing felt that the aircraft needed to be designed for the American market, with six-abreast seating and the ability to use runways as short as 4,500 feet (1,400 m).
In 1960, Pratt & Whitney was looking for a customer for its new JT8D turbofan design study, based on its J52 (JT8A) turbojet, while United and Eastern were interested in a Pratt & Whitney alternative to the RB163 Spey. Once Pratt & Whitney agreed to go ahead with development of the JT8D, Eddie Rickenbacker, chairman of the board of Eastern, told Boeing that the airline preferred the JT8D for its 727s. Boeing had not offered the JT8D, as it was about 1,000 lb (450 kg) heavier than the RB163, though slightly more powerful; the RB163 was also further along in development than the JT8D. Boeing reluctantly agreed to offer the JT8D as an option on the 727, and it later became the sole powerplant.
With high-lift devices on its wing, the 727 could use shorter runways than most earlier jets (e.g. the 4,800 ft (1,500 m) runway at Key West International Airport).
A later 727 model, the 727-200, was stretched by 20 feet (6.10 metres) to carry 58 more passengers and replaced earlier jet airliners on short- and medium-haul routes such as the Boeing 707 and Douglas DC-8, as well as aging propeller airliners such as the DC-4, DC-6, DC-7, and the Lockheed Constellations.
For over a decade, more 727s were built per year than any other jet airliner; in 1984, production ended with 1,832 built and 1,831 delivered, the highest total for any jet airliner until the 737 surpassed it in the early 1990s.
Design
The airliner's middle engine (engine 2) at the very rear of the fuselage gets air from an inlet ahead of the vertical fin through an S-shaped duct. This S-duct proved to be troublesome in that flow distortion in the duct induced a surge in the centerline engine on the take-off of the first flight of the 727-100. This was fixed by the addition of several large vortex generators in the inside of the first bend of the duct.
The 727 was designed for smaller airports, so independence from ground facilities was an important requirement. This led to one of the 727's most distinctive features: the built-in airstair that opens from the rear underbelly of the fuselage, which initially could be opened in flight. Hijacker D. B. Cooper used this hatch when he parachuted from the back of a 727, as it was flying over the Pacific Northwest. Boeing subsequently modified the design with the Cooper vane so that the airstair could not be lowered in flight. The design included an auxiliary power unit (APU), which allowed electrical and air-conditioning systems to run independently of a ground-based power supply, and without having to start one of the main engines. An unusual design feature is that the APU is mounted in a hole in the keel beam web, in the main landing gear bay. The 727 is equipped with a retractable tailskid that is designed to protect the aircraft in the event of an over-rotation on takeoff. The 727's fuselage has an outer diameter of 148 inches (3.8 m). This allows six-abreast seating (three per side) and a single aisle when 18-inch (46 cm) wide coach-class seats are installed.
Variants
Data from: Boeing Aircraft since 1916.
The two series of 727 are the initial -100 (originally only two figures as in -30), which was launched in 1960 and entered service in February 1964, and the -200 series, which was launched in 1965 and entered service in December 1967.
The first 727-100 (N7001U) flew on February 9, 1963. FAA type approval was awarded on December 24 of that year, with initial delivery to United Airlines on October 29, 1963, to allow pilot training to commence. The first 727 passenger service was flown by Eastern Air Lines on February 1, 1964, between Miami, Washington, DC, and Philadelphia.
A total of 571 Boeing 727-00/100 series aircraft were delivered (407 -100s, 53 -100Cs, and 111 -100QCs), the last in October 1972. One 727-100 was retained by Boeing, bringing total production to 572.
The -100 designation was assigned retroactively to distinguish the original short-body version. Prior to the introduction of the 727-200, all short-body aircraft followed a "727-00" pattern. Aircraft were delivered for United Airlines as 727-22, for American Airlines as 727-23 and these designations were retained even after the advent of the 727-200. However, short-body aircraft ordered after the introduction of the 727-200 followed the new "727-100" pattern (i.e. 727-123 for American Airlines).
Convertible passenger cargo version, additional freight door and strengthened floor and floor beams, three alternative fits:
94 mixed-class passengers
52 mixed-class passengers and four cargo pallets (22,700 lb or 10,300 kg)
Eight cargo pallets (38,000 lb or 17,000 kg)
QC stands for Quick Change. This is similar to the convertible version with a roller-bearing floor for palletised galley and seating and cargo to allow a much faster changeover time of 30 minutes.
QF stands for Quiet Freighter. A cargo conversion for United Parcel Service, these were re-engined with Stage 3-compliant Rolls-Royce Tay turbofans.
A single 727-30 acquired from the Federal Aviation Administration, this aircraft was originally delivered to Lufthansa. It served mostly with United States Southern Command flying from Panama City / Howard Air Force Base.
Four 727-35 aircraft were acquired from National Airlines by the United States Air Force for transporting Air National Guard and National Guard personnel.
A stretched version of the 727-100, the -200 is 20 feet (6.1 m) longer (153 feet 2 inches or 46.69 metres) than the -100 (133 feet 2 inches or 40.59 metres). A 10 ft (3.0 m) fuselage section ("plug") was added in front of the wings and another 10 ft fuselage section was added behind them. The wing span and height remain the same on both the -100 and -200 (108 and 34 feet (33 and 10 m), respectively). The original 727-200 had the same maximum gross weight as the 727-100; however, as the aircraft evolved, a series of higher gross weights and more powerful engines were introduced along with other improvements, and from line number 881, 727-200s are dubbed -200 Advanced. The aircraft gross weight eventually increased from 169,000 to 209,500 pounds (76,700 to 95,000 kg) for the latest versions. The dorsal intake of the number-two engine was also redesigned to be round in shape, rather than oval as it was on the -100 series.
The first 727-200 flew on July 27, 1967, and received FAA certification on November 30, 1967. The first delivery was made on December 14, 1967, to Northeast Airlines. A total of 310 727-200s were delivered before the -200 was replaced on the production line by the 727-200 Advanced in 1972.
A convertible passenger cargo version; only one was built.
727-200 Advanced
The Advanced version of the 727-200 was introduced in 1970. It featured powerful engines, fuel capacity and MTOW (185,800–210,000 lb or 84.3–95.3 t) increased the range from 1,930 to 2,550 nmi (3,570 to 4,720 km; 2,220 to 2,930 mi) or by 32%. After the first delivery in mid-1972, Boeing eventually raised production to more than a hundred per year to meet demand by the late 1970s.
