CLEARING EQUIPMENT IS PREVIOUS (REALLY BETWEEN THE AIRCRAFT

The proposed utility model relates to the lighting equipment of mainly aircraft, for example, helicopters, and is used to ensure the possibility of flying at night, allowing you to use: Night vision devices, such as night vision goggles, eliminating the influence of light sources on them, such as inside the cockpit both inside and outside of it.

The search revealed a utility model for the interior of the lighting equipment certificate No. 6383 of 08/26/97. ShK 6 B64D 47/02, which is selected by the authors as the closest analogue to the claimed utility model.

Known in-cab lighting equipment of a predominantly aircraft apparatus for night operation includes general and local floodlights located near devices, panels and control panels, and is equipped with light filters, installations on the inner surface of the optically transparent lamp element, and made in the form of a polyamide film with an international | coating and coe $ .ii: transmittance 20 - 60.

However, this technical solution has several disadvantages: low film transmission coefficient (not exceeding 60), low durability associated with intensive aging of the film and its destruction due to the influence of thermal and light radiation and vibration of the aircraft.

The proposed utility model allows you to adapt lighting equipment to night-vision devices, for example, to night-vision goggles, thus ensuring the possibility of flying at night, by eliminating the influence of lighting, both inside the cabin and outside it, on night-vision devices, due to the use of filters, however, in order to eliminate the above drawbacks, namely, in order to: 1 increase the coefficient of allowance and increase the accuracy and durability of light filters they are made of glass with a multilayer inter Feetzmonnigl coated

($ ig. 1 - comparative spectral characteristics)

- 2 pieces, can be accessed through the use of color filters made of colored glass with tuye., I.e. providing the cutoff of radiation in the sensitivity range of CIRCUITS of night vision, spectral characteristics (Fig. 2 or by the use of light filters in the form of a packet of 2-3 glasses with different spectral characteristics, but such a DRY spectral characteristic that is required to eliminate the effect of radiation of light sources on night-time devices Vision ($ ig.Z. So, lighting equipment of a predominantly flying vehicle has been proposed for work with night vision devices, in particular with night vision cameras, sensitive in the F-region of the spectrum to the visible range border, containing light sources equipped with light (| filters, cut off radiation in the sensitivity range of night-vision devices, different from TRM, that the filters are made of :) glass with a multilayer interference coating, 2) from colored glass with the required spectral characteristic, H) in the form of a package of glasses with the required total spectral characteristic.

The implementation of the filters in this way will allow, in addition to achieving the main task - adapting lighting equipment to work with night vision devices, to eliminate a number of prototype deficiencies, namely: to increase the transmittance of the filters and increase their strength characteristics, by eliminating the polyamity film,

On the appendix: x drawings it is shown:

Fig. 4, Fig. 5, Fig. 6 - sketches of light filters with inter, irrelevant coating times;

The positive effect of the proposed solution contributed to the achievement of the main goal - ensuring night flights is also to increase the transmittance of filters to 80-90 (with polyamide squash no more -, and to the tach to increase the strength characteristics of the filter (vibration affects the polyamide film,

temperature change, etc.) while the interference coating is much more durable.
