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.

The power plant of the McDonnell Douglas DC-8 passenger aircraft is represented by four turbofan aircraft engines, which can develop a power of 84,5 kN each (depending on the production series). The cruising speed of the McDonnell Douglas DC-8 passenger airliner was about 950 km / h (depending on the modification), and the flight range could vary from 9518 kilometers to 12139 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

 

McDonnell Douglas DC-8 Series 10 models had a power plant consisting of four Pratt & Whitney JT3C-6 turbojet aircraft engines developing 60,5 kN each. Models of the current series were designed exclusively for operation in the United States of America, and all 29 aircraft built were distributed between two national air 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.

The McDonnell Douglas DC-8 Series 20 aircraft received more advanced Pratt & Whitney JT4A-3 turbojet engines with a total thrust of 283,2 kN (70,8 kN each), as well as an increased passenger compartment, allowing to take on board 12 more passengers. The models of this version did not receive any significant changes, while the production of aircraft related to this version was completed after 15 aircraft were 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.

Models of the McDonnell Douglas DC-8 Series 40 series did not receive any significant changes in comparison with the Series 30 aircraft - the only exception was the new, more advanced Rolls-Royce Conway 509 turbojet engines, which are efficient 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.
