5.2The NVS 6 design employs a binocular pattern, i.e. it consists of two identical optoelectronic channels (of monocular type) which afford stereoscopic vision to create comfortable conditions for napping off the earth, thus enabling the pilot to evaluate the space depth and ensure higher night flight safety.
5.3The general view of the NVS 6 is illustrated in Fig. 5.1.
5.3.1Lenses (1) may be focused either relative to distant objects located in the space outside the cockpit, or relative to the objects located close to the helicopter. The focus is adjusted by rotating the lenses.
5.3.2The dioptric focusing of eyepieces (2) is carried out individually for each sight channel of the unit by rotating eyepieces with the aid of focusing rings (3).
5.3.3The independent power source (IPS) is arranged inside guide (4), which is closed with
5.3.4The NVS 6 is installed onto the pilot’s helmet by attachment of fixing assembly (6) of the unit to mount (7), which is then secured to helmet casing (8).
The fixing assembly makes it possible to perform individual adjustment, so as to provide the most comfortable position of the goggles mounted on the helmet relative to the pilot’s eyes. This feature enables the pilot to move the goggles away from the eyes, tilt the optical axes of monocular pair and displace them upwards and downwards.
