Abstract

The invention is in the field of aircrafts. The technical proposal allows the increase of passenger aircraft with six or more rotors a loading capacity and to improve their manageability. By using different rotors for draws up and perform maneuvers the effect is ensured. During the flight the average rotor speed, providing the agility, not decreasing. To reduce the inertia rotor diameter to ensure maneuverability and weight are limited. The invention can be used for passenger aircraft, which is economically feasible for use with fixed rotor blade angle of attack. Invention is required for the realization of such a flying machine frame, which can be installed separately shunting and flight rotors as well as microprocessor based controller which controls the rotor according to the described algorithm.

Description

Išradimas yra susijęs su sraigtasparniais - skraidymo aparatais su keliais keliančiais rotoriais.The invention relates to helicopters - aircraft with several lifting rotors.

Patente GB2455374 yra aprašytas skraidantis aparatas su keliais keliančiais rotoriais. Aparate yra įmontuoti rotoriai su fiksuotu menčių atakos kampu. Aparatas yra valdomas, keičiant rotorių sukimosi greitį. Rotoriai turi būti lengvi ir mažo skersmens, idant būtų galima greitai padidinti arba sumažinti jų sukimosi greitį. Šis reikalavimas apriboja aparato keliamąją galią. Kitas tokių aparatų trūkumas - jų valdomumas leidžiantis yra daug prastesnis nei kylant. Tai yra sąlygojama rotorių sukimosi greičio sumažėjimu leidžiantis aparatui.GB2455374 describes a flying machine with several lifting rotors. The machine has built-in rotors with a fixed blade angle of attack. The machine is controlled by changing the rotational speed of the rotors. The rotors must be lightweight and small in diameter so that their speed can be increased or decreased quickly. This requirement limits the carrying capacity of the machine. Another disadvantage of such apparatus is that its handling ability is much poorer than when rising. This is due to a reduction in the rotational speed of the rotors as the machine runs.

Išradimo tikslas - padidinti lengvųjų skraidymo aparatų su keliais keliančiais rotoriais keliamąją galią, taip pat patobulinti jų valdomumą leidžiantis.The object of the invention is to increase the carrying capacity of light aircraft with several lifting rotors and to improve their maneuverability by lowering.

Nustatytas uždavinys yra sprendžiamas, palikus didelį dalies rotorių sukimosi greitį visuose skrydžio režimuose. Toliau šie rotoriai yra vadinami „manevriniais“. Inertiškumui sumažinti manevriniai rotoriai yra nedidelio skersmens ir nedidelio svorio. Tai leidžia greitai keisti jų sukimosi greitį manevrui atlikti. Bendra manevrinių rotorių trauka yra nepakankama aparato laikymuisi ore. Papildomi rotoriai yra skirti bendrai traukai padidinti. Toliau šie rotoriai yra vadinami „traukos“ rotoriais. Traukos rotoriai gali būti didesnio skersmens ir svorio nei manevriniai. Yra geriau, kai traukos rotoriai yra sumontuoti arčiau aparato centro, o manevriniai - palei perimetrą. Prieš skrydį pirmiausia yra įvaromi manevriniai rotoriai, o po to traukai padidinti yra įvaromi traukos rotoriai. Didžiausia trauka yra užtikrinama, kuomet visi rotoriai dirba maksimaliu sukimosi greičiu.The identified task is solved by maintaining a high rotation speed of some rotors in all flight modes. Hereinafter, these rotors are called "maneuvers". To reduce inertia, maneuver rotors are small in diameter and light in weight. This allows them to quickly change their rotational speed to perform the maneuver. The overall thrust of the maneuvering rotors is insufficient to hold the machine in the air. Additional rotors are designed to increase overall thrust. Hereinafter, these rotors are called "thrust" rotors. Thrust rotors can be larger in diameter and weight than maneuvers. It is preferable to have thrust rotors mounted closer to the center of the machine and maneuvers along the perimeter. Before the flight, the maneuvering rotors are first thrust and then the thrust rotors are thrust to increase thrust. Maximum thrust is achieved when all rotors are running at maximum speed.

Fig. 1 yra parodytas skraidantis aparatas su šešiais rotoriais. Pažymėtos pozicijos: 1 - skraidančio aparato korpusas; 2, 3, - traukos rotoriai; 4, 5, 6, 7 - manevriniai rotoriai.FIG. 1 shows a flying machine with six rotors. Marked positions: 1 - airframe; 2, 3, - thrust rotors; 4, 5, 6, 7 - Maneuver rotors.

Išradimas yra taikytinas lengviesiems skraidymo aparatams, kuriuose ekonomiškai tikslinga naudoti rotorius su fiksuotu menčių atakos kampu.The invention is applicable to light aircraft, in which it is economically feasible to use rotors with a fixed angle of attack of the blades.

Išradimo realizavimui yra reikalingas skraidymo aparatas su tokiu rėmu, kuriame galima atskirai sumontuoti manevrinius ir traukos rotorius, taip pat mikroprocesorinis valdiklis, valdantis rotorius pagal aprašytą algoritmą.An embodiment of the invention requires an aircraft with a frame in which maneuver and thrust rotors can be mounted separately, as well as a microprocessor controller controlling the rotors according to the algorithm described.
