Description

The invention relates to aircraft and is intended for use in organizing training for pilots and consolidating aerobatic skills.

Known aircraft containing the fuselage, a propeller mounted in the nose of the fuselage, a power unit for driving a screw, a trapezoidal wing, the chords of which are located in the same plane with the construction horizontal of the fuselage and the axis of the screw, ailerons located on the wing, the ailerons control device, horizontal and vertical plumage (SU 764275 A, B 64 C 1/26, 12/10/1980).

A disadvantage of the known aircraft is associated with a narrow field of practical use, determined mainly by the sports orientation with limited capabilities when performing aerobatics.

Closest to the proposed is a training aircraft Yak-52, containing the fuselage with the front cockpit of the trainee and the rear cockpit of the instructor, a propeller mounted in the nose of the fuselage with the location of the axis of the screw and the horizontal construction of the fuselage in one plane, a power plant for driving the screw, trapezoidal wing, consisting of half wings with ailerons and brake flaps, horizontal and vertical plumage, retractable landing gear complex of avionics with aerobatic navigation display system information and technological information (Jane′s. All the word′s Aircraft. 1994-95, p. 281). The specified aircraft has the following disadvantages:

restrictions when performing reverse aerobatics;

insufficient flight range;

the student’s cabin is not equipped with means for training in instrument flight;

instrumentation does not provide night flights in simple weather conditions;

the possibility of safe pitch stall is not provided;

there is no rescue system to safely leave the aircraft in flight.

The objective of the invention is the creation of a training aircraft with high aerobatic and maneuverability characteristics in all flight modes when performing complex complexes of aerobatics.

The problem is solved in that in the training aircraft containing the fuselage with the front cockpit of the trainee and the rear cockpit of the instructor, a propeller mounted in the nose of the fuselage with the axis of the screw and the horizontal construction of the fuselage in one plane, the power unit for driving the screw, trapezoid wing, consisting of half wings with ailerons and brake flaps, horizontal and vertical plumage, retractable landing gear, a complex of avionics with a flight-navigation indication system and technological information — vortex generators are installed along the leading edge and on the upper surface of each wing with the possibility of redistributing the aerodynamic load, a blind flight curtain with the ability to control from the instructor’s cabin is placed in the student’s cabin, the power plant consists of a four-stroke air-cooled engine and a three-bladed propeller , caissons were made in the root of each wing console, forced security rescue systems were installed in the seats of both cabs the meat leaving the aircraft in flight, set of on-board equipment is equipped with a secure storage of the flight information.

It should be noted that vortex generators are already used on aircraft (RU 2001110058 A, B 63 C 1/00, 05.20.2003). However, in known technical solutions, these generators are installed in the area of the trailing edge of each wing and reduce the vortices arising behind the aircraft, i.e. have a different purpose than the proposed aircraft.

Figure 1 presents a side view of the proposed aircraft, and figure 2 is a front view. Figure 3 shows the image of the wing of the aircraft with additional vortex generators.

The Yak-52 M training aircraft contains a fuselage 1, a propeller 2, a power unit (not shown) for propeller 2, a trapezoidal wing 3 consisting of half wings 4 and 5 with ailerons 6 and brake shields (not shown), horizontal trapezoidal tail 7 and vertical tail 8, tricycle landing gear 9 retractable with hollow springs, vortex generators 10 and 11, 12 and 13 installed with the possibility of redistribution of aerodynamic load, blind blind 14 placed in the student’s cabin 15 with the possibility of control from booths 16 instructors.

The construction horizontal 17 of the fuselage 1 and the axis of the propeller 2 are located in the same plane. The power plant consists of a four-stroke air-cooled engine and a three-bladed propeller. In the root part of each wing console, caissons (not shown) are made. In the seats of both cabins 15 and 16, rescue systems for compulsory safe leaving the aircraft in flight (not shown) were installed. The on-board equipment complex (not shown) with the flight-navigation and technological information display system is equipped with a secure flight information storage device (not shown).

During the operation of the aircraft, the necessary thrust is created using the propeller 2 and the power plant, and the aerodynamic lift force is achieved through the half-wings 4 and 5. The ailerons 6 control the aircraft by roll and pitch (while simultaneously deflecting the left and right ailerons in

opposite sides), and the brake flaps are braked.

When using this aircraft are provided:

Instrument flight training under curtain 14 during approach using the landing system;

training to fly day and night in simple weather conditions;

safe pitch stall;

performing a corkscrew with improved characteristics;

aerobatics training;

learning how to get out of a corkscrew;

training in actions with the system of forced departure from the aircraft in flight.

Thus, the proposed aircraft is characterized by high aerobatic and maneuverability characteristics in all flight modes
