The Beriev Be-2500 Neptun (Бериев Бе-2500 Нептун) is a project of a super-heavy amphibious transport aircraft . The maximum take-off mass is estimated at 2500 tons.

construction

The development of the Be-2500 aims on the one hand to complete transcontinental flights at cruising altitude of jet aircraft with a lower payload, as well as to fly intercontinental at a ground-effect cruising altitude of ekranoplanes close to the surface of the water, this with the entire payload. The concept comes from the earlier WWA-14 . The aircraft is therefore predestined for intercontinental routes and for operations from seaports, where only relatively minor adjustments are necessary. According to the manufacturer, the machine would also be the ideal device to bring spaceships close to the equator and then into a starting position in the upper atmosphere.

There are two versions, which differ in the arrangement of the gears and in the geometric design of the structure. Initially, plans were made with the NK-116 engine from the Kuznetsov design office in Samara , which had been conceptualized until 1994 . However, foreign engines were also considered, including the Rolls-Royce Trent 800 , which only delivers half of the desired output.

If it were to go into service, the Be-2500 would become the largest aircraft in the world.

Stage of development

Concepts of such aircraft were developed in the 1980s by the Beriev design office in collaboration with ZAGI and ZIAM . One concept was called Be-5000. Saving the landing gear on super-heavy aircraft could increase efficiency, while at the same time the seaworthiness of a large machine allows it to operate at greater wave heights, thus reducing weather-related operating shutdowns.

To achieve this, Beriev planned to work with foreign partners on the development of the aircraft, including financing issues. It was estimated by 2008 that the cost of the development program would reach $ 10-15 billion. The project was presented in September 2000 at the Hydro Aviation Show 2000 in Gelendzhik . Models could be seen in the following years in Farnborough in 2004 and in Paris in 2007. The project did not appear to be part of the Ministry of Industry’s government’s Aviation Industry Development 2013–2025 program.
