The developers of the Ukrainian An-178 made a mistake with the alignment of the plane
During the first flight tests of the first built Antonov prototype of a new transport aircraft An-178 has detected an important problem with the alignment machine, because of significant miscalculations In the design.
"in the end, to ensure proper alignment the Aircraft has to perform all the long test and ferry flights with additional ballast weight 1, 32 tons in the form of a package of fifteen steel plates weighing 85-90 kg each, laid just behind the cockpit ", ? inform the blog bmpd.
An error with calculating the alignment of the An-178 was found on the first prototype aircraft with the serial number 001 and registration UR-EXP. As specialists say, with this ballast a prototype of An-178 was flown to the air show in Le Bourget, and now in Dubai, besides after landing the ballast is discharged quickly to hide the fact of his presence on the plane. Thus continuous availability of the ballast degrades the parameters of the aircraft, and without, apparently, hardly appropriate advertising data, the proposed GP " Antonov ". According to one version, the cause of incorrect alignment machine was adopted at the design stage in 2012, the decision to increase the wingspan of the An-178 on 2 meters, as well as the area of the wing with 88, 5 98, 6 square meters, While maintaining unchanged the fuselage is already designed. It is planned that this decision was due to apparent design failure takeoff and landing characteristics compared to the claimed. According to experts, the defect is "organic" and are difficult structurally. It is suggested that a means of defect correction of alignment may be to increase the length of the fuselage in the area of the wing and the bow, However, this will require serious redesign of the structure of the new experimental flight model, and, really, a new program testing redesigned the plane. In September Ukraine has presented the An-178 at the Dubai Airshow-2015 in UAE. However, As said Deputy Minister of economic development and trade of Ukraine An-178 was not able to participate in demo flights, As it was " not ready ", RIA " Novosti-Ukraine ". Remember the long promised and many times postponed the presentation of the new aircraft marks of the Academy of Sciences in April, held in Kiev. The an-178, As stated, shall be the replacement of the old Soviet model of An-12. The aircraft was shown with great fanfare, But there are doubts whether it the market. In June of the current year Ukraine told about the intention to produce the aircraft, as well as among them the An-178, together with Poland. The state enterprise "Antonov" (Kiev) has announced plans to offer the market advanced transport Aircraft An-178, built on the location of the passenger An-158. Dostoinstvom An-178 General designer of SE "Antonov" Dmitry Kiva called the ability to move the sea containers and certain types of military equipment.
