Description

FIELD OF THE INVENTION This invention relates to aeronautical engineering, in particular to multi-body aircraft with propellers.

The purpose of the invention is to increase reliability.

Figure 1 shows a General view of the aircraft; Fig. 2 is a side view of the pivoting mechanism for creating a vertical link with a screw; in Fig.Z - the same, longitudinal section.

The airplane contains three fuselles. 1, the middle of which is intended for the carriage of goods, and the last two are for the carriage of passengers, the power plant 2 with power drives 3 and traction arms 4. mounted on the wings x 5 connecting the fuselage 1. Power drives 3 connected to the shafts 6 of the screws 4 using rotation mechanisms 7, each of which contains a housing 8 with a spike 9 and a hole 10 in which the drive shaft 3 of the power plant is installed with a clearance

a bevel gear 11 fixed thereon, a rotary bracket 12 with an aperture in which a shaft 13 of a lifting screw 4 is mounted with a bevel gear 4 fixed thereon, interacting with a bevel gear 11 of a power plant 3, a worm to 15 with a power drive 16 moreover, the swivel bracket is pivotally mounted on the housing 8 and interacts with the spike 9, at the end of the swivel bracket 12 there is a worm sector 17 interacting with the worm 15,

The device operates as follows.

Powertrain torque

is transmitted to the screws 4 by means of a shaft 3 s, gear 11 and shaft 13 with gear 14.

To change the direction of the thrust vector of the screw 4, the actuator 16 moves

the worm to 15 and rotates the bracket 12 together with the screw 4.

Claims (2)
