Abstract

FIELD: aviation.

SUBSTANCE: invention relates to aircraft and air transport. Manned two-seat vertical take-off-landing aircraft is driven by an electric motor in the form of an adapted motor-wheel with a rotor mounted on a power shell of the turbine, and stator is mounted on frame pylons, with rail-type annular wing with centrally located on its transverse axis hull with cockpit fixed in space. Annular wing can turn about transverse axis under influence of moments from aerodynamic rudders installed in main planes of vehicle, redistributing thrust between lift and pushing force in direction of motion course. On top of annular wing frame there is a liquid compensator of reactive aerodynamic force of annular wing turbine, in particular, a reactor which generates a torque of the opposite sign on the wing due to the fluid moving in the direction opposite to the turbine rotation and pumped by the electric screw turbine along the annular tube of the reactor.

Description

1. Technical field

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

2. State of the art

According to the level of technology, the described aircraft has an analogue (prototype) of aircraft represented by patents RU 2268845 C2 dated 04/12/2004, RU 2307768 C1 dated 02/14/2006, RU 2380287 dated 04/02/2008 and RU 2483980 dated 11/11/2011 .

3. Essence of the invention

This manned vertical take-off and landing aircraft has the dimensions of a passenger car and is built on the principle of a rotating annular rail-type wing used in the projects described in the patents above, namely, to create control torques when transferring the aircraft from hovering mode to forward motion mode or For movement in the lateral direction, four aerodynamic rudders are used, mounted on the frame of the annular wing along its outer contour on the main axes of the device and pushed into the air flow thrown by the turbine. In the case of flight in a forward direction, the annular wing rotates relative to the main transverse axis of the vehicle at an angle within ±90° (Fig. 3), converting excess lift into thrust. In this case, the body of the apparatus, located in the center of the annular wing, maintains its position in space, since it is hingedly suspended on the consoles of the annular wing, coaxial with the transverse axis of the apparatus.

What is new in this project is the use of an adapted electric wheel motor as a motor, the rotor of which (solenoids) is mounted on the external power shell of the annular wing turbine, and the stator with its magnetic circuit is mounted on the external pylons of the frame. This design solution provides the device with high torque.

Also new in the project is a method of combating the reactive aerodynamic moment that occurs during rotation of the annular wing turbine. It is a liquid compensator (reactor) located at the top of the annular wing frame in the form of an annular pipe filled with liquid pumped by an electric screw turbine in the direction of reverse rotation of the annular wing turbine.

4. Brief description of the drawing

The layout of this aircraft is presented in three views: right view (Fig. 1), top view (Fig. 2) and in-flight view (Fig. 3).

The right view (Fig. 1) shows the body (1) with the cockpit (2), the annular wing (3), consisting of a truss frame (4) with pylons (5) and (6), on which the turbine (7) is suspended ), fixed between two double shells and creating a traction force during rotation. Each pair of shells consists of a power shell (with a power set) and an assembly shell (for mounting turbine blades). The annular wing is hinged on bearings and connected to the body by two consoles (8) and can be rotated at significant angles within ±90°, ensuring energetic movement of the aircraft in the forward direction. Impulses for turning the annular wing are given by four aerodynamic rudders (9).

The annular wing turbine is driven by an electric motor, which is an adapted wheel motor mounted on the external power shell and external pylons. The motor-wheel rotor, consisting of dual solenoids (10), is mounted on the power shell of the turbine, and the stator (11) with its magnetic core is mounted on the outer pylons of the annular wing (6). In view of the unpretentiousness of power sources in terms of volume and location, as well as means of delivering electricity to the executive bodies of the engine, their design, allowing placement both on the turbine and in the body of the apparatus, will be decided on the basis of feasibility.

The reaction torque from the rotation of the annular wing turbine is counteracted by a liquid compensator (reactor), which is an annular pipe (12), through which an electric screw turbine (13) pumps liquid in the direction opposite to the rotation of the annular wing turbine.

The rotation of the annular wing relative to the transverse axis of the aircraft is carried out by four aerodynamic rudders, pushed into the air flow thrown by the turbine of the annular wing.

The top view drawing of the aircraft (Fig. 2) explains the relative position of the structural elements.

5. Carrying out the invention

The proposed design has a minimum of optimally interconnected components, does not have mechanical gearboxes and transmissions, is easier to manufacture, and therefore at the current level of technology seems quite feasible.
