Engine

FIELD: devices for creation of aero- or hydrodynamic forces for transport facilities with the aid of rotating members.

SUBSTANCE: proposed engine has housing and two cones with surfaces rotating in opposite directions. Rotating surfaces are provided with cells in form of tooth spaces and teeth. Teeth on surface of front cone are bent in way of flow around the cell and teeth on surface of rear cone are bent towards incoming flow which is circular in shape and is caused by rotation of surfaces of cones. Surface of each tooth space has form of question-mark in section. As a result, reduced pressure is built-up in cells of rotating surface of front cone and increased pressure is built-up in cells of rotating surface of rear cone, thus creating the thrust along axis of rotation of cones.

EFFECT: extended field of application of thrust creating devices for various vehicles running in air and water media.

The present invention relates to engines that can operate in air and water environments.

Currently known screw and jet engines, air and water vehicles. The closest analogue of the invention is an aircraft engine, comprising a housing and cones with rotating surfaces - patent SU 4458 A1; 31.01.1928. However, the scheme of this engine is complex, but are created by the cones additional aerodynamic forces are relatively small.

The proposed engine includes a housing with front and rear cones, and the front surface of the cone is made of rotating in one direction, and back to the opposite direction.

On the front surface of the cone caused the cells depicted in figure 1, representing the alternating depressions and curved teeth, and the ends of the prongs are curved in the direction of the ambient flow cell and the inner surface of the cavity is similar in cross section to the question mark. The thread is basically circular, passing along such a cell, it creates a vacuum.

On the rear surface of the cone caused the same cell, only the teeth have curved towards their flowing stream. Flow, mainly circular, passing along such a cell, it creates increased pressure.

In the drawings shown:

Figure 1 - ball is s, in which an underpressure is created from flowing;

Figure 2 - cell, which creates increased pressure from flowing;

Figure 3 - an underwater vehicle with two cones;

Figure 4 - aerial, vertical flying machine with rotating cones (upper and lower);

Figure 5 is a plane with rotating cones;

Figure 6 - a heavy, large-capacity aircraft with rotating cones (front and rear).

The aircraft (figures 5 and 6) additionally, in case there is one, and the other two sets of rotating cones with vertical axis of rotation, which create vertical lift force (they are shown in section). As a consequence, they do not need wings and chassis, they have only the tail stabilizer. Optionally, the same cell to be mounted on the upper and lower surfaces of the body which will create lift during horizontal flight.

Theoretically you can imagine and space vehicles with similar engines, which can be used for vertical lifting to a certain limit for their height and horizontal acceleration within the boundaries of the atmosphere, and then can be included jet engines. This may reduce the launch weight of the spacecraft during launch into space, and the weakening of the C the dependence on the starting point.

The proposed engine allows the apparatus to move also on the water surface and under water, and then fly up in the air.

It can be expected that at a certain choice of the parameters cell size cones and speed of their rotation before one of the cones (e.g., the front) there is sufficient negative pressure, as in a whirlwind, as the thread will be tied, in particular, the friction on the surface of the cone.

Engine, comprising a housing and two cone with rotating surfaces, characterized in that the rotating in opposite directions, the surfaces of the cones marked cells representing the alternating depressions and teeth, bent on the front surface of the cone in the direction of the ambient flow, and on the rear surface of the cone in the direction towards the flowing stream, the surface of each depression in cross section similar to a question mark, so that in cells of a rotating surface of the front cone creates a reduced pressure, and the cells rotating surface of the rear cone is under high pressure.

SUBSTANCE: invention relates to flight and water vehicles, particularly to changing their aerodynamic characteristics to create lifting and pushing forces. The proposed device incorporates a fixed and movable disks fitted in parallel, the latter coupled with the engine and furnished with radial vanes. The free ribs of the vanes face the said fixed disk and are mounted with a gap relative to the said disk, its size being notably smaller than the vane height.
