Design and development of the aircraft McDonnell Douglas DC-8 50 began in the mid-years of the last century, at the same time, the aircraft meets all modern requirements, providing a safe and comfortable air travel for passengers.

The first flight airliner McDonnell Douglas DC-8 was committed 30 May 1958 years, and, beginning in the design has been admitted a few nuances that during the year were corrected, and in September 1959 years airliner was officially presented to the public, and on par with those launched in mass production.

Airliner McDonnell Douglas DC-8 was equipped with modern avionics means that the flights made as convenient as possible for the crew, and at the same time providing the aircraft to the appropriate security conditions. Among other things, developed the design according to many experts has been very successful, and then it is on the basis of the fuselage of the aircraft created such world-famous aircraft as the McDonnell Douglas DC-10, Boeing 747, Lockheed L-1011 TriStar and others.

Powerplant airliner McDonnell Douglas DC-8 represented by four turbofan aircraft engines, allowing to develop the capacity of 84,5 kN each (depending on the release of the series). Cruising speed passenger airliner McDonnell Douglas DC-8 was about 950 km \ h (depending on version), and the flight distance can vary from 9518 12139 kilometers to kilometers.

Depending on the interior and modification of passenger aircraft, could accommodate up to 269 people on board the vessel, thereby providing a very efficient transport of passengers on most routes, which is observed at present.

 

Modifications McDonnell Douglas DC-8

 

Models McDonnell Douglas DC-8 Series 10 possessed power plant consisting of four turbojet aircraft engines Pratt & Whitney JT3C-6 60,5 developing capacity in kN each. Models of the current series have been designed exclusively for the operation on the territory of the United States of America, and all built 29 aircraft were distributed between the two national carriers - United Airlines (22 aircraft) and Delta Air Lines (9 aircraft). Current series has not been worthy of attention on the part of airlines, which is why the release of the aircraft was rather short-lived.

Aircraft McDonnell Douglas DC-8 Series 20 got better turbojets Pratt & Whitney JT4A-3 have general thrust of 283,2 kN (70,8 kN each), as well as increased passenger cabin, allowing to take on board more passengers on 12. There were no significant changes in this version of the model is not received, at the same time, production of aircraft belonging to this version was completed after 15 aircraft was built.

Planes Series McDonnell Douglas DC-8 Series 30 exploited to carry out intercontinental air travel, while American engineers have increased the fuselage of the aircraft, increased capacity of fuel tanks, and vastly improved interior cabin, allowing to place on board to passengers 176. Among other things, aircraft manufacturers have increased the angle of action of the flaps, making handling and maneuverability of the aircraft increased slightly.

Series models McDonnell Douglas DC-8 Series 40, any significant changes compared with the aircraft Series 30 not received - except just become a new, more sophisticated turbojets Rolls-Royce Conway 509, effective in operation, more reliable and produce less noise.

Models related to a series of aircraft McDonnell Douglas DC-8 Series 50, as major changes have received a new thrust turbojet engines increased, and additional passenger seats in the cabin (on board could accommodate up to 179 passengers depending on cabin configuration). Planes of this series is well proven, and for all the time of release 88 aircraft was built.

Series aircraft McDonnell Douglas DC-8 Series 60 was well-designed, and taking into account the requirements of the majority of potential customers, the aircraft fuselage length has been increased by almost 12 meters (57,1 meters), which in turn allowed to place on the board to 269 passengers. Changes were also made to the powerplant, avionics, etc., so that the series has become the most popular among the air carriers around the world, and particularly the US airlines,

Series McDonnell Douglas DC-8 Super Seventies appeared in 80-ies, already immediately after the release of the passenger aircraft of this type. However, aircraft manufacturers have presented three basic models that were much more powerful than preceding them, and allowed to be placed on board to passengers 269 performing flights over distances up to 11278 kilometers. The models have been converted from aircraft 60-Series, and in the period up to 1988 years 110 descended from the conveyor planes, some of which are still used by a number of airlines.
