SURA-I HELMET-MOUNTED TARGET DESIGNATION AND INDICATION SYSTEM

The SURA-I Helmet-Mounted Target Designation and Indication System (HMTDIS) is the upgraded version of the production-run Sura HMTDS offering the new advantage: it displays aiming and flight information in the pilot's field of view.


The SURA-I Helmet-Mounted Target Designation and Indication System (HMTDIS) is the upgraded version of the production-run Sura HMTDS offering the new advantage: it displays aiming and flight information in the pilot's field of view.

The HMTDIS receives signals from the airborne system and generates the indicative marks (symbols, alphanumeric information) displayed in the pilot's field of view.

The type and volume of the displayed data will be specified with the Customer.

The data display field of view: 6x4°.The production-run Sura HMTDIS upgrade is fulfilled by changing a helmet unit and two boards in the electronic module.

The production-run helmet unit and the new one are identical by form, weight, dimensions, docking, mechanical and electric parameters.

The upgrade can be performed in the exploitation places directly.

The warranty lifetime of the HMTDS is extended due to upgrade.

 

Field of application

 

SURA Helmet-Mounted Target Designation System (HMTDS) can be used both in fixed-wind aircraft and helicopters for off-boresight aiming of guided weapon (IR missiles, turret gun) and viewing systems at visual targets.

 

Product status

 

Flight-tested, under production, adopted for Su-30 series aircrafts.

 

SURA and SURA-I HMTDS

COMPARATIVE CHARACTERISTIC

Helmet-mounted target designation system (HMTDS) with indication (SURA-I) was developed as a modernization and improvement project of SURA HMTDS in order to increase HMTDS application efficiency in close air combat modes.

During development the data exchange protocol between HMTDS and RIF complex of Su-30MKI aircraft, HMTDS airborne units connection circuits were kept. Also the SURA HMTDS combat application identity was provided so there is no need to change the flight personnel training program.

Modernization consists in:

- improvement of helmet unit (liquid crystal matrix is used as image forming element);

- replacement of CPU and electronic block check unit.

 

SURA-I HMTDS order code example: «СУРА АЖИЮ.201219.002-001»

SURA-I HMTDS is designed for:

1. Determination of angular coordinates (in azimuth (У) and elevation angle (Z)) of sighting

line of visually observed object.

2. Operational aiming of guided weapons (guided missiles, cannon turrets) and surveillance

systems to visible objects by turn of the pilot’s head without changing aircraft course in aircraft

coordinate system.

3. Forming and indication of single commands and flight & navigation indication in pilot’s FOV.

SURA-I HMTDS has 5-level noise immunity degree implemented, outer parameters failures are eliminated.
