Abstract

FIELD: aircraft engineering.

SUBSTANCE: proposed aircraft consists of airframe comprising cockpit, engine compartment and wings module. Wings module comprises one bearing multi-line circular wing with blades distributed in both circumference and height (modular propeller). Circular tube comprises two blade pumps forcing fluid in direction opposite that of modular propeller rotation to compensate for reactive moment of the wing. Turn of the wings module is driven by two pair of opposed aerodynamic control surfaces and shifting weights along wings module outer outline towards its inclination. Power is transmitted from engines by two hollow shafts arranged on both side of airframe and gears fitted on shat extensions, said gears being in mesh with rack arranged along the modular propeller rim.

EFFECT: reduced load on transmission, improved controllability and efficiency of modular propeller.

Description

1. The technical field

The present invention relates to the technical fields of aircraft and air transport.

2. The level of technology

In the prior art, the described aircraft has an analogue (prototype) aircraft “Turbolet” and “Turbolet-M”, represented by patents RU 2268845 C2, 04/12/2004 and RU 2307768 C1, 02/14/2006, respectively.

3. The invention

Aircraft "Turbolet-M2" (hereinafter referred to as "turbolet") consists of a hull (Fig. 1, p. 1), combining the cockpit and the technical compartment with engines, fuel reserves, landing system and other systems important for the functioning of the turbolet, and a wing module that can rotate, similarly to Turbolet-M, around two cantilever beams fixed on the sides of the hull along its transverse axis and passing inside the drive hollow drive shafts.

In this invention, unlike prototypes, only one annular wing, located below the cantilever beams, creates lift. The reduction of two annular wings, as in the prototypes, into one improves the aerodynamic characteristics of the blades. In addition, this annular wing is such that its height (thickness) significantly exceeds the profile height of a single blade, which allows you to distribute the blades not only around the circumference, but also in height to exclude their mutual influence. Such an annular wing, in fact, is a package of 4 blade propellers, in this case, placed one above the other with an offset, which allows us to call this design a “batch propeller”.

To compensate for the reactive moment from the batch propeller over the cantilever beams, a “liquid” flywheel (reactor) is mounted on the wing module, an annular tube with two built-in pumps (from the condition of symmetry) pumping the fluid in the direction opposite to the rotation of the batch propeller.

Rotations of the wing module around the cantilever beams are carried out not only due to the efforts of the aerodynamic rudders operating in the air stream of the propeller, as in the prototypes, but also under the influence of loads displaced in the plane of the wing module in the direction of rotation along its outer contour. Four independent weights along the outer contour of the wing module complement and duplicate the work of the aerodynamic rudders, increasing the control efficiency of the device, and, in addition, they can successfully solve the problem of centering the wing module relative to the axis of rotation when it rotates around cantilever beams.

To create a lifting force, the power from the engines from the engine compartment of the turbo-turbine body is transmitted to the batch propeller through two hollow shafts on the sides of the apparatus and gears fixed to their outer ends, which are in gearing with the rack along the rim of the batch propeller.

The presence of a single batch propeller allowed the gear to be moved close to the casing, which led to a decrease in the rotational speeds of both the gear and the high-altitude ring wing, reducing the load on the transmission.

4. Brief Description of the Drawings

The layout of the turbo is presented in two forms: a rear view (figure 1) and a top view (figure 2).

Figure 1 shows the housing (1) with the cockpit and the engine compartment, a wing module, consisting of a supporting frame of a truss (2) with shells fixed on it, between which one batch propeller (3) rotates with 32 blades distributed over circles into 4 groups, and in height - into 8 groups. The wing module is connected to the hull by two cantilever beams (4), around which it can rotate through angles of ± 90 °, providing translational movement of the aircraft. The impulses for turns to the wing module are given by the aerodynamic rudders (5), as well as the loads moving inside the pipeline (6).

The drive to the batch propeller consists of engines (7), gearboxes (8), hollow shafts (9), coaxial with the support cantilever beams and gears at their ends (10), which are rack and pinion with the rim of the batch propeller.

Compensation of the reactive moment from the batch propeller is carried out by a “liquid” flywheel (reactor), which is an annular tube (11) with two built-in vane pumps (12), pumping liquid in the direction opposite to the rotation of the batch propeller. The pumps are driven through the transmission (13) from the pinion gear (10).

Figure 2 explains the relative position of structural elements.

5. The implementation of the invention

The proposed design has fewer constituent elements, is better organized, easier to manufacture, and therefore at the current level of technology seems to be achievable.
