Project 2500
“2500” – amphibious aircraft, which had a central plane – flying wing the size of a football field and a mass of 2500 tons. The upper surface of the aircraft could well serve as a flying aircraft carrier deck. The ends of the center-ended fyuzelyazheobraznymi bortotsekami, below which is mounted retractable in-flight elastic floats tsilendricheskoy form, and on the aft keels and floats stabilizers. Engines that provide translational velocity, located in front of the center-mounted on pylons, and were thus protected from dust, water and other things.

Block turbojet engines was put forward on the pylon in order to exhaust gases came under the wing and its ash. The gap between the trailing edge of the wing and the water was regulated rotation flap-flap. When starting guard was completely rejected. In this case, the gas flow was hindered, the rate fell, pressure grew. Was formed dynamic air cushion that supports the device from the moment of launch before entering the flight regime of the water.

At the same time to present issues of energy such an apparatus, which must make long trips to the extreme conditions of the oceans, the Arctic and Antarctic. Since the use of chemical fuel limits the range and duration of the flight winged, then studied the possibility of using Yasu. Such a device would be used at cruising flight in a long time. At the start, before entering the display mode of flight, scheduled intermittent use of boost with the filing of chemical fuel into the combustion chamber of engines.

The crew of passengers, cargo and equipment – all housed in the center section and bortotsekah. Genius Bartini made central plane – flying wing stable and in normal flight, and flying a dynamic air cushion using on-screen effect. For the most part this was achieved by setting the plane of the two wings of consoles in the rear.

Airplane “2500” was provided with a hoisting engine installed in the center-mines from opening scoop on the top surface. Management system vertical takeoff and landing included gas-stream management and traction lift engine. Elastic floats for an emergency landing on water or land had skuloobrazovateli, Reda, as well as runners with a compressed air through the perforation partitions between the two longitudinal inflatable stringers.
