Description

In the proposed high-altitude automatic corrector of the mixture of aircraft engines, depending on the flight altitude, the change in the position of the mixture regulator is caused by a sectioned solenoid connected to intermediate relays connected to the contact altimeter circuit.

The drawing shows a diagram of the high-altitude automatic corrector mixture.

An altimeter is installed on the plane (or rather, just a barometer), the arrow 3 of which is connected to the membrane through round 2. At the end of the arrow there is a sliding Contact 4, which, when the membrane position changes, slides across sectors 5, 6, 7, 8, etc. Consequently, contact of contact 4 with one or the other sector is connected with a certain flight height, since the membrane changes its position in relation to the atmospheric pressure. Then, several nro.intermediate relays of 9, 16, 18, 19, etc., are installed on the aircraft (their number depends on the number of control levels, for example, adjustment 1000, 500 m, etc.) . Each relay has a ser / dec, winding 10, measles 12,

contact plate. reinforced on the bark, and two pairs of contacts — 14 and 15 (except for the first relay, where there is only a pair of contacts 13}. The relay is the simplest electromagnet and can be made in any form (P-shaped and M-shaped and t p.) and their weight can be very insignificant, as well as the size. In addition, a solenoid 33 is installed on the plane, having sections 25, 26, 27, 28, etc. (according to the number of relays). Inside the solenoid there is a core 24, which can be moved along a guide rod 23 made of a non-magnetic material. The rod 23 is mounted on a stand 20 and 29 and has a groove in which the rod 30, which is connected to the core 24, and passes through the hole in the rack 29, moves. When the rod 30 moves, the yoke 31 moves, connected to the axis of the HIGH adjuster 32. under the action of the spring 21 is in the left end of the solenoid (in the left on the drawing).

When the plane flies at a low altitude (suppose that the altitude is less than 3000 m), arrow 3 has a non-.ibDJoe deviation, and the clock 4 is not

comes to the first working sector 5. If the flight height now increases, suppose up to 3500 m, and if, say, it is necessary to adjust the gas at this height, the position of the arrow 3 will be such that switch 4 will be on sector 5. Then the circuit closes supply relay 9 (the circuit is visible in the drawing from the set and the aircraft generator, through the arrow and (contact, on sector 5, into the coil: relay 9 and through the closed contacts 15 into the network). Anchor 12 pull, and 11 l contact plate contact 13 to thereby closes the target of section 25 of the solenoid 33. Included and the 25 W section has no core 24, and the latter moves into the | Nutri solenoid. This movement of the core to the “initial position through the rod 30 will cause the position of the plug 31 to change, and therefore, the axis of the height regulator 1g of the torus 32 will also turn by some angle, which will cause a corresponding change in the mode of the mixture. Suppose that it is desirable that the gas is adjusted every 500 m. Sectors 5, 6, etc., and the distances between them are located with this calculation. As you climb, arrow 3 will move to the right. At 4000 m, it will be in sector 6. Thus, the coil circuit of relay 16 is closed. The anchor of relay 16 is turned on, and the contact bar closes contacts 14 and the circuit of section 26 of solenoid 33 is turned on. Connect with relay bark 16, contact bar moves away from contacts 15, and the cegp, the casting coil 9, opens, and the core 24, under the action of the magnetic field of section 26, shifts to the right, in the middle of section 26. This again will cause some rotation of the axis of the regulator 32, and consequently ,; gno, and the corresponding change in the mode of the mixture. To eliminate the core oscillation at the moment of transition from sector to sector, the contacts on the relay are arranged so that when the core is attracted to the contact bar, the contacts are first closed and then the upper ones open, i.e. the working section of the solenoid is turned off only after the next section is turned on . The same, caiMoe, Go is reversed in the reverse order when the height is lost. Ksx can be seen from the description, the device is easy to manufacture and set up. Its dimensions (when mounting the relay and the solenoid in one casing) are approximately 250X200X100 mm to adjust the mixture every 500 m in the range of 4,000 to 10,000 m. The power consumption of the device feed power is approximately 150-200 watt. The use of intermediate relays makes it possible to very easily slip KOIItalka 4 across sectors and a slight burning of sectors, which is very important for devices with a contact arrow. The spring 21 serves to hold the core 24 in the initial position during a high-altitude flight. A sufficiently intense magnetic field will allow the core 24 to remain in place even in the case of centrifugal and centripetal forces at different maneuvers of the aircraft.
