Description

The invention relates to the field of aircraft modeling and relates mainly to bench tests of aircraft with moving wings.

Known aircraft (aircraft) containing the fuselage with the supporting wings mounted across it, the engine, the cockpit, passenger and / or cargo compartments, tail, landing gear [1].

The objective of the invention is to increase the compactness of the aircraft in non-flying conditions.

The technical result is achieved in that in an aircraft containing a fuselage with load-bearing wings mounted across it, an engine, a cockpit, passenger and / or cargo compartments, a tail, a landing gear, wings are made to rotate and “fold” along the fuselage. The wings on the wide side have a flat gear sector with a hole for mounting on the shaft, with each gear sector mounted rotatably between the upper and lower common plates fixed motionless on the fuselage, while the teeth of the sectors are in contact.

Figure 1 presents a model of an aircraft with wings moving relative to the fuselage, front view (wings are "folded" along the fuselage); figure 2 shows a top view of figure 1 (dashed lines show the possible positions of the wings); figure 3 shows a view of figure 2 by A; figure 4 shows a fragment of a wing with a gear sector; figure 5 shows a possible diagram of the rotation rotation mechanism.

An aircraft, for example, an airplane model, contains a fuselage 1 with load-bearing wings 2, an engine 3, a crew cabin 4, a passenger and / or cargo compartment 5, a tail unit 6, a landing gear 7. The engine built into the fuselage can be a screw (Fig. 1-3 ), turboprop, jet. The wings are made with the possibility of rotation and "folding" along the fuselage in the direction of the tail. The wings in cross section have a flat lower and curved upper surface with lift when moving in air. Each wing on the wide side has a flat gear sector 8 with a central hole 9 for mounting on the shaft 10. Each gear sector is installed (without play) between the common upper and lower plates, respectively 11 and 12, fixed stationary on the fuselage. Between the tooth sectors and flat fixed plates, balls 13 can be placed to form a “ball bearing” (not shown). The teeth of 14 sectors are in contact with the formation of the "gear". At least one gear sector is connected by a shaft to a rotation rotation mechanism 15 located in the fuselage, for example, comprising a hydraulic cylinder 16, a gear rack 17, gears (gears) 18.

An airplane model is made comprising a fuselage 1 with an engine 3, a crew cabin 4, a passenger and / or cargo compartment 5, a tail unit 6, a landing gear 7. On the fuselage (above, above the center of gravity), plates 11 and 12 are fixed with and resting between them on balls 13 of "ball bearings" with gear sectors 8 rigidly connected to the wings 2. Gear sectors having teeth 14, holes 9 for the shaft 10 are connected to the rotation rotation mechanism 15 located in the fuselage. When creating the necessary pressure of the working medium (liquid) in the hydraulic cylinder 16, the gear rack 17 occupies a position (corresponding to the pressure of the medium), forcing the gears (gears) 18 to be rotated, rigidly connected by shafts to the gear sectors of the wings. By setting the required pressure of the working medium in the hydraulic cylinder, the wings can be “folded” along the fuselage or given a different angular position (possible positions of the wings are shown by dashed lines in Figs. 1-3).

This embodiment of the aircraft allows you to determine the best location of the wings relative to the fuselage during bench tests; to change the position of the wings at its launch, flight and landing, to sharply reduce the area it occupies when parking in hangars and at airfields.
