Description

The invention relates to training devices, in particular for ground training of hang gliders, and can be used by pilots to process flight skills of operating light gliders.

A device for ground training of glider pilots is known, comprising a boom pivotally connected to a stand. At one end of the boom there is a permanent counterweight, and at the other is a frame to which training glider 1 is attached.

Known aviation simulator, containing the base, to which is attached a frame with counterweights. A boom is fixed on the frame, at one end of which the object of research is placed, on the second there are mounted movable weights that are moved to the position specified by the control panel along the guide beam by an electric motor 2.

The disadvantage of the simulator is that the center of gravity of the weights of the counterweights moves only along the axis of the boom, which creates a uniform change in the torque of the boom when it is rotated.

The aim of the invention is to expand the didactic capabilities of the simulator by creating a diverse pattern of changes in boom torque.

The goal is achieved by the fact that a glider connected to a vertical mast and a training object, successively connected to an actuator control panel and the first engine, kinematically connected through a lead screw with a guide beam, are inserted into the glider simulator, which contains a boom boom, and a first engine motor and screw bracing, as well as outrigger and safety spreader, with one ends connected with screw diagonal and the other ends rigidly connected with the corresponding sections of the boom S, hingedly connected to the guide beam, the input of the second electric motor is connected to the second output of the drive control panel.

FIG. 1 shows a functional diagram of the simulator; in fig. 2 - kinematic scheme; in fig. 3 shows the characteristics of the torques acting on the lifting boom.

The glider simulator contains (Fig. 1) a vertical mast 1, a lifting boom 2, a guiding beam 3, a counterweight 4 fixed movably on the guiding beam 3, an outrigger 5 rigidly connected to the lifting boom 2 at its base, a screw diagonal 6 with an electric motor 7, forming a kinematic block, one end pivotally attached to the end of the guide beam 3, and the other to the top of the outrigger- 5, safety rope stretch 8, retracted to the end part of the lifting boom 2, electric motor 9 with lead screw 10 for moving the counter Chapter 4, individual hinges with one, two, and three degrees of freedom, respectively, 11- ", remote control 14 for controlling the electric screw brace and counterweight, training object 15.

Glider simulator works as follows.

A training object 15 is attached to the triaxial joint 13, for example a hang glider with a pilot. From the remote control 14, the position of the counterweight 4 is set in which the boom 2 with the guide beam 3 would be in a balanced state. The angular and linear positions of the counterweight 4 determine the desired character of the resultant torsion boom 2 of the moment. The kinematic diagram of the simulator (Fig. 2) shows the acting forces on the boom 2 and the beam 3. These forces create torques of different signs. The total torque of 0 is given by

M Rlo (co5 "(- Rdr 1 cos (L-i-y), where M is the total torsion boom 2);

Rd - weight of the glider and pilot; L - shoulder arrows 2; Rlr weight counterweight 4; I - counterweight shoulder; If is the angle between the horizontal of the boom and the line passing through the axis of rotation of the boom and the center t of the rigidity A of the counterweight 4.

We divide both sides of equation (1) by the value of Pd L and denote

   Mi COS (fl (+ t)

FIG. Figure 3 shows the graphs of the total torque M / Mo versus the angle cx of the position of the boom at certain characteristic values of Mo and angles; curve 16 - Mo 0.5 and U 0; curve 17 - Mo 1; Y 30 °; curve 18 - Mo 1; T -30 °; curve 19 - ms, 0.5,. 30 °; curve 20 - Mo 0.5, T -30 °; curve 21 - 5 Mo 1.5, 5G 30 °; curve 22 - Mi 1,5, f -30 °.

As can be seen from the graphs, with K. O (curve 10 total moment represents a cosine curve, where the maximum is reached only at l O and the minimum at L 90 °. At different positions of the counterweight, the cosinusoids differ only in amplitude and sign. Raising or lowering the center of gravity of the counterweight above or below the axis boom, the nature of the total torque relative to the torque at Y 0 varies significantly; 5 the maximum torque value can be achieved at a given angle (curve 19),

or balance the system at a given angle L (curve 18, 20, 21 at the points of intersection of the axis l), or specify the desired change in the total torque.

Practically, the screw brace 6 should allow the bending angle to be changed within (-30) ° - (+30) °. With a wing span of about 10 m, the length of the lifting boom is 8 m, and the guide beam is 2-2.5 m.

Compared with the basic simulator, which has a stable position of the center of gravity of the counterweight relative to the lifting boom, the proposed simulator has the ability during the workout to change the position of the counterweight in the direction of the boom

and in the vertical plane. This allows the trainer to set the desired torque pattern of the boom (Fig. 3) and most effectively simulate actual flight conditions, i.e. air dynamics and various piloting techniques on a particular hang glider.

The deviation of the center of gravity of the counterweight from the axis of the boom in the vertical plane according to the calculations carried out and the data of experimental verification allows creating a wide range of training modes. In addition, on the proposed simulator, it is possible to test hang gliders of any class, determine their aerodynamic parameters, ensuring complete safety.
